More and more people are interested in energy-saving heating systems. Ways to save energy are a significant nuance when choosing a heating system. The latest technology in this matter is infrared heating and induction boilers, solar heating and smart home systems.

The essence of energy saving

First, we want to reveal one little secret. You may be surprised, but any electric heaters are energy saving. After all, what does this term mean for a device that produces thermal energy? It means that the energy contained in fuel or electricity is converted by a boiler or heater into heat as efficiently as possible, and the degree of this efficiency is characterized by the efficiency of the unit.

So, all electrical appliances for heating rooms have an efficiency of 98-99%; not a single heat source that burns different types of fuel can boast of this indicator. Even in practice, so-called energy-saving electric heating systems emit 98-99 W of heat, consuming 100 W of electricity. We repeat, this statement is true for any electric heaters - from cheap fan heaters to the most expensive infrared systems and boilers.

Comparative example. On average, 1 kg of dry firewood emits 4.8 kW of heat during combustion, but in reality we can only get 3.6 kW, since the boiler efficiency is 75%. An electric heater is much more efficient, consuming 4.8 kW from the network and delivering 4.75 kW to the house.

A truly energy-efficient heating system is a heat pump or solar panel. But there are no miracles here either, these devices simply take energy from the environment and transfer it into the house, practically without consuming electricity from the network, for which you have to pay. Another thing is that such installations are very expensive, and our goal is, as an example, to consider available new market products that are declared as energy-saving. These include:

• infrared heating systems;
• induction energy-saving electric boilers for heating.

Types of devices

There are a wide variety of IR panels available today. Based on your needs, you can easily select the appropriate equipment.

According to such a parameter as the installation method, it is divided into two main types :

1. Mounted. These devices are distinguished by a colored body made of metal. It heats up thanks to the emitter installed in the structure. After installation using fasteners on the wall, the infrared panel is ready for use; you just need to plug it into a power outlet.
2. Built-in. Thermal infrared panels of this type have plasterboard as a base, on which two layers of emitter are placed, as well as insulation. An IR emitter is installed in the upper part - a carbon conductive thread. On top of it is a protective polymer coating. The devices are connected to a 220 V network.

There are also designer panels for placement on the wall ; they can have different sizes and colors. Panels in the form of plinths are also available in stores. Placed around the perimeter of the room, they replace the usual baseboard.

If you finish the walls using plasterboard, then you can use infrared wall heating as the main source of thermal energy. If the apartment has the usual cast iron radiators, such a device will be a good option for backup heating.

Ways to improve energy efficiency at home

You can reduce energy costs used for heating using different methods:

• increasing the energy efficiency of the building;
• the use of the Smart Home system, as well as other automation that allows minimizing costs;
• reducing electrical losses using radiators and other devices;
• increasing the efficiency of heating boilers or furnaces;
• using environmentally friendly types of energy (firewood, solar panels).

A combination of two or more options can be used to achieve better results.

Even the most reliable and high-quality heating system will not bring much benefit if large-scale heat loss occurs in the house, so measures should be taken to prevent heat energy from leaking through cracks and open vents.

It is important to take simple but effective steps by covering floors, walls, doors, ceilings, and window frames with thermal insulation material. In addition to insulation, additional insulation can be placed according to regulatory requirements. This will further reduce heat loss, thereby increasing the energy efficiency of the building.

To carry out high-quality thermal insulation, you can call a specialist energy auditor. He will carry out a thermal imaging survey of the house, which will reveal the places of the most intense heat loss, the insulation of which must be carried out first.

As a rule, the greatest heat loss occurs through the walls, the attic floor, and the floor along the joists. These areas require high-quality thermal insulation. To prevent heat loss through windows, you can use shutters that close at night.

Infrared heating systems

The operating principle of infrared heating devices of any design is to convert electricity into heat, releasing the latter in the form of infrared radiation. With the help of this radiation, the device heats all surfaces located in its area of ​​​​action, and then the air in the room warms up from them. Unlike convective heat, such heat does not affect a person’s well-being and in this regard is considered the best option.

For reference. Heat flow includes 2 components: radiant and convective. The first is infrared radiation coming from heated surfaces. The second is direct air heating. All infrared heating systems, made using energy-saving technology, transfer 90% of the heat by radiation and only 10% is spent on heating the air. At the same time, the efficiency of the heaters remains unchanged - 99%.

There are 2 types of infrared systems that are considered new on the modern market and are gaining increasing popularity:

• long-wave ceiling heaters;
• film floor systems.

Unlike the usual UFO type heaters, long-wave emitters do not glow, since their heating elements operate on a different principle. The aluminum plate is heated by a heating element attached to it to a temperature of no more than 600 ºС and produces a directed flow of infrared radiation with a wavelength of up to 100 microns. A device with plates is suspended from the ceiling and heats surfaces located in its area of ​​action.

In fact, such energy-saving electric heating systems will provide exactly as much heat to the room as the energy consumed from the network. They will just do it in a different way, through radiation. A person can feel the heat flow only when directly under the heater.

To raise the air temperature in a room, such systems, unlike convective systems, require a lot of time. This is not surprising, because heat transfer does not occur directly to the air, but through intermediaries - floors, walls and other surfaces.

Intermediaries also use PLEN underfloor heating systems. These are 2 layers of durable film with a carbon heating element between them, to reflect heat upward, the bottom layer is coated with silver paste. The film is laid on the screed or between the joists under the floor covering made of laminate or other materials. This coating serves as an intermediary; the system first heats the laminate, and from it the heat is transferred to the air in the room.

It turns out that the floor covering converts infrared heat into convective heat, which also takes time. The so-called energy-saving heating of the house using film heated floors still has the same efficiency - 99%. What then is the real advantage of such systems? It consists in uniform heating, while the equipment does not occupy the usable space of the room. And installation in this case cannot be compared in complexity with a water heated floor or radiator system.

Application of infrared panels

Heated thermal panels work well in a wide range of applications. Examples:

• heating of apartments, houses, holiday homes, winter gardens;
• heating of offices, conference rooms;
• heating of shops, service points, trading areas;
• heating of halls, warehouses, workshops, loading ramps;
• heating of exhibition and exhibition halls;
• communal heating;
• heating schools, kindergartens,
• heating of museums and galleries;
• heating of catering establishments;
• heating of hotels, sanatoriums, shelters;
• heating of hospitals and sanatoriums;
• heating of churches and places of worship;
• heating of sports halls, entertainment halls, sports halls;
• heating in zoological and botanical gardens;
• heating in livestock and crop production;
• heating in saunas, swimming pools and fitness clubs and much more.

Induction electric boilers

This new product appeared on the market relatively recently and aroused considerable interest, since it was advertised as another energy-saving installation. In reality, this water heater uses the law of electromagnetic induction, according to which a stationary steel rod placed inside a coil with current flowing through it will heat up. There are no tricks here, the so-called energy-saving boiler operates with an efficiency of about 98-99%, like its other electric “brothers”.

The clear advantage of the unit is that the coolant passing through it does not come into contact with important elements, but only with the metal rod. Therefore, the boiler can reliably serve for many years without any maintenance other than periodic flushing. Other advantages of the induction apparatus are:

• small dimensions and weight, which is very important when placing the heat generator in the combustion room;
• rapid heating of the coolant.

“Question-answer” section

On the topic of infrared panels, you can find a lot of identical questions on the Internet, which are the first thing that comes to a person who decides to install them at home. We have consolidated the most common of them and prepared a kind of TOP questionnaire with detailed answers.

— How long will IR panels last me?

— Their average service life is 25 years. Whether they will work for you more or less depends on the mode in which you operate them and whether you follow the care rules.

— What is sold complete with the IR panel? Are any other materials or components needed for its installation and operation?

— The standard configuration of the device includes the heater itself and a wire with a plug. For subsequent installation and connection, you also need electrical wires, a thermostat in the socket, if it is not structurally provided for, automatic switches, magnetic starters and possibly other automatic devices (depending on the characteristics of the heating system).

You will also need brackets, dowels, screws, and self-tapping screws for fastening, but in most cases they also come as a kit.

— Do panels from different manufacturers have different dimensions or are the standardized dimensions the same for all?

— The length may differ - 1 m and 1.5 m. The first is on models with a power of 0.6 kW, the second is for 1 and 1.3 kW. The width and thickness are the same for all devices - 16.5 cm and 4 cm, respectively.

— What acts as a heating element in the panel?

— It is a low-temperature heating element mounted in an aluminum plate, which acts as a radiator.

— How much does the ceiling IR panel weigh?

— It all depends on the power of the model. For configurations at 0.6 kW, the weight is 3.5 kg, for power 1 and 1.3 kW - 4.5 kg.

— My ceiling is covered with plastic. Will the panel light it up? Does it get very hot?

— Its body practically does not heat up, as it is thermally insulated. Therefore, installation is possible on surfaces made of any materials. You don't have to be afraid of fire.

Infrared heating devices can be mounted on any surface. They work well with any building and finishing materials without the risk of fire

— Is it possible to leave the plates turned on unattended?

— Yes, if they are equipped with a thermostat. If not, it is not recommended to leave it unattended for a long time to avoid overheating of the room.

— How many thermostats do you need?

— One thermostat per room.

— How much electricity is consumed with such heating? If a model with a power of 1 kW will it “wind up” 1 kW/hour?

— If you approach operation wisely, then, of course, no. The whole secret is that to maintain a comfortable temperature, it is enough for the panel to work for 20-30 minutes per hour.

It is not necessary to monitor the operation of an infrared heating panel equipped with a built-in thermostat or similar device in the outlet. It will turn off automatically when it reaches the temperature selected by the owner.

If you install a thermostat, the heater will not work constantly. It will turn on as needed. If the heating operates for 20-30 minutes per hour, electricity consumption will be from 1/3 to 1/2 of the device’s power.

Thermal panels – energy-saving heating

Among energy-saving heating systems, thermal panels are becoming especially popular. Their advantages are economical energy consumption, functionality, and ease of use. The heating element consumes 50 Watts of electricity to warm up per 1 m², while traditional electric heating systems consume at least 100 Watts per 1 m².

A special heat-accumulating coating is applied to the back side of the energy-saving panel, due to which the surface heats up to 90 degrees and actively releases heat. Heating of the room occurs due to convection. The panels are absolutely reliable and safe. They can be installed in children's rooms, playrooms, schools, hospitals, private homes, and offices. They are adapted to voltage fluctuations in the electrical network and are not afraid of water and dust.

An additional “bonus” is the stylish appearance. The devices fit into any design. Installation is not difficult; all necessary fasteners are supplied with the panels. From the first minutes of turning on the device, you can feel the warmth. In addition to the air, the walls warm up. The only negative is that using panels is unprofitable in the off-season, when you only need to slightly heat the room.

Information on infrared heating

Infrared thermal panels are direct heaters. The technology is based on the use of light waves from the region below the visible region of red light (long infrared waves IR-C*). This heat can be compared to the sun's rays. Infrared radiation is completely natural and safe. Moreover, it works well for consumers (used in maternity hospitals for many years). The most visible source of infrared heat wave is, of course, the Sun. Using room heating based on infrared heating panels, you bring a small solar home! The waves emitted by the panels reach the body without heating the air, creating a feeling of soothing warmth and comfort.

Infrared radiation waves are divided into three types: short wavelengths near visible light IR-A (>700°C), medium wavelengths IR-B (about 250–700°C) and long wavelengths IR-C (<250°C). A person is able to sense infrared heat waves when the temperature of a given object is above 22°C, but, of course, the higher the surface temperature, the greater the susceptibility of the heat wave.

Energy saving using monolithic quartz thermal electric heaters

You can save energy if, for example, you use quartz thermal electric heaters. Such efficient heating of a private home converts electrical energy into heat. The quartz sand contained in heating elements retains heat for a long time after the power supply is turned off.

What are the advantages of quartz panels:

1. Affordable price.
2. Quite a long service life.
3. High efficiency.
4. Relatively low energy consumption.
5. Convenience and ease of equipment installation.
6. No oxygen burnout in the building.
7. Fire and electrical safety.

Monolithic quartz thermal electric heater

Energy-saving heating panels are made using a solution made using quartz sand, which ensures good heat transfer and a long service life. Thanks to the presence of quartz sand, the heater retains heat well even when the power is turned off, and can heat up to 15 cubic meters of a building. The production of these panels began in 1997, and every year they become more and more popular due to their energy saving. Many buildings, including schools, are switching to this energy-saving heating system.

This heating system is made of modules connected in parallel, and how many there will be depends on the size of the room. Another plus is the possibility of automatic control.

Types of energy sources

Traditionally, several energy sources are used for heating:

Solid fuel – a tribute to traditions

For heating, wood, coal, peat briquettes, and pellets are used. Solid fuel boilers and stoves can hardly be called economical or environmentally friendly, but the use of new technologies can significantly reduce fuel consumption and, as a consequence, the amount of combustion products emitted into the atmosphere.

In recent years, the number of sales of gas-fired furnaces and boilers has been increasing. Their advantages are complete combustion of fuel and the use of pyrolysis gas as a heat source. Installing such a boiler saves energy resources. We recommend purchasing such solid fuel boilers from trusted retailers.

The operating principle of a pyrolysis (gas generator) boiler is based on the use of pyrolysis gas, which is used as fuel. The wood in such a boiler does not burn, but smolders, due to which a portion of the fuel burns much longer than usual and produces more heat.

Liquid fuel is expensive, but popular

These are liquefied gas, diesel fuel, used oil, etc. Heating a home always consumes a large amount of liquid fuel, and no methods have yet been invented to significantly reduce consumption. This heating equipment requires careful maintenance, regular cleaning of soot and soot.

Most types of liquid fuel have another drawback - high cost. And yet, despite the obvious shortcomings, liquid fuel boilers are in second place in popularity after gas ones.

Liquid fuel boilers are convenient in cases where there is no gas pipeline near the house and you need to install a completely independent heating system

Gas is available and cheap

In traditional gas boilers, fuel consumption is high, but condensing models have solved this problem. Their installation allows you to obtain maximum heat with minimal gas consumption. The efficiency of condensing boilers can reach more than 100%. Many models of well-known brands can be converted to run on liquefied gas. To do this you just need to change the nozzle. Another energy-saving option is infrared gas heating.

Condensing boilers are a new word in the production of gas heating equipment. They consume fuel economically, are highly efficient, and are ideal for heating and hot water supply in private homes.

Electricity is a convenient and safe source of heat

The only disadvantage of using electricity for heating is the high cost. However, this issue is being resolved: electric heating systems are constantly being developed that consume a relatively small amount of energy and provide efficient heating. Such systems include heated floors, film heaters, and infrared radiators.

Warm floors are most often used as an additional or alternative heating system for a home. The advantage of this type of heating is that the air is heated at the level of human height, i.e. the principle “feet warm, head cold” is implemented

Heat pumps – economical and environmentally friendly installations

The systems operate on the principle of converting the thermal energy of the earth or air. The first heat pumps began to be installed in private homes back in the 80s of the twentieth century, but at that time only very wealthy people could afford them.

Every year the cost of installations becomes lower and lower, and in many countries they have become very popular. Thus, in Sweden, heat pumps heat about 70% of all buildings. Some countries are even developing building codes obliging developers to install geothermal and air heating systems.

Heat pumps are installed by residents of the USA, Japan, Sweden and other European countries. Some craftsmen assemble them with their own hands. This is a great way to get energy to heat your home and save the environment

Solar systems are a promising source of energy

Solar thermal systems convert radiant solar energy for heating and hot water. Today, there are several types of systems that use solar panels and collectors. They differ in cost, production complexity, and ease of use.

Every year more and more new developments appear, the capabilities of solar systems are expanding, and prices for structures are falling. While it is unprofitable to install them for large industrial buildings, they are quite suitable for heating and hot water supply of a private home.

Solar thermal systems require only initial costs - purchase and installation. Once installed and configured, they work autonomously. Solar energy is used for heating

Use of solar energy

Solar heat is an environmentally friendly and quite effective source for a number of heating systems. Some modifications use electricity as additional power, others operate only from solar cells. In some cases, there is no need for additional equipment - sunlight is enough.

Air modular manifolds

Solar panels (collectors) are installed on the south side of the building at such an angle that their heating by the sun's rays is maximum. The system operates in automatic mode: when the air temperature drops below a set point, air is driven through the heating modules using fans. One air battery allows you to heat a room of up to 40 m², respectively, a set of collectors can serve the entire house.

For the southern regions, modular solar air collectors are quite effective and inexpensive equipment for creating a heating system.

Solar modules are environmentally friendly and cost-effective; they are convenient to use in conjunction with other heating systems as a backup energy source. The design of the devices is simple, so there are DIY plans for assembling solar panels. Ready-made collectors are also affordable and quickly pay for themselves. The only thing you need to do before purchasing them is to calculate the power of the equipment and the size of the modules.

In cottages and country houses, solar panels are installed for backup power supply of low-power DC Volts or 220 Volt AC loads

Air-water collectors

Hot water supply systems powered by solar energy are also suitable for any climate. The principle of operation of the system is simple: water heated in the collectors flows through pipes into a storage tank, and from it throughout the house. The liquid constantly circulates under the action of the pump, so the process is continuous. Several solar collectors and two large tanks can provide heat to a country house - of course, provided there is enough sun. High-temperature collectors allow you to install “warm floors”.

Solar hot water supply systems do not pollute the air at all and do not create noise, but their installation requires additional equipment: a pump, a pair of storage tanks, a boiler, a pipeline

The advantage of equipment operating on water collectors is environmental friendliness. Silence and clean air inside the house are no less important than heating and hot water. Before installing solar collectors, it is necessary to calculate how effective they will be in a particular case, because all the nuances are important for proper operation: from the installation location to the estimated power of the devices. One drawback should also be taken into account - in areas with a long summer period, excess heated water will appear, which will have to be drained into the ground.

Passive solar heating

Passive solar heating does not require any additional equipment. The main conditions are three factors:

• perfect tightness and thermal insulation of the house;
• sunny, cloudless weather;
• optimal location of the house in relation to the sun.

One of the options suitable for installing such a system is a frame house with large glass windows facing south. The sun heats the house both from the outside and from the inside, as its heat is absorbed by the walls and floors.

With the help of passive solar equipment, without the use of power and expensive pumps, you can save 60-80% of heating costs for a private home

Thanks to the passive system, savings on heating costs exceed 80% in sunny areas. In the northern regions, this heating method is not effective, so it is used as an additional one.

All energy-saving heating systems have advantages over conventional ones; the main thing is to choose the most optimal, possibly a combined option that combines operational efficiency and resource savings.

Arguments for and against IR panels

Those who plan to install infrared heating panels at home naturally want to know not only about their advantages, but also about the points that may cause inconvenience. Therefore, below is an objective assessment of both the positive aspects and disadvantages of this heating method.

The following arguments in favor can be given in favor of infrared panels:

1. Impact resistance and increased strength. IR panels are not afraid of even shocks and falls. And all thanks to its shockproof body and heavy-duty materials.
2. Easy installation and simple operation. You just need to fix the panel on the wall or ceiling and plug it into a power outlet. This does not require any special knowledge, a welding machine, etc.
3. Low energy consumption. Firstly, there are no energy losses for heating the air. Secondly, IR radiation reduces the overall temperature of the space by 3-5 ºС, which allows saving energy up to 25%. That is, the air temperature is felt on average 5 degrees higher than the one shown by the thermometer when measured. And all because not only the air that is being measured heats up, but also the objects in the room and even the person himself.
4. Quiet operation. Such heaters will not “crack” or “gurgle”, which means they will not interfere with sleep and other vital processes.
5. Independence from power surges. Even if the voltage changes, this will not affect the operation of the heater.
6. Maintaining normal air humidity. IR thermal panels do not dry out the air, like other electric convectors, which make breathing difficult and dry out the mucous membranes. They do not allow air mixing (cold/warm), so dust caused by heated air masses does not rise.
7. Compact dimensions and lack of associated equipment. There is no need to install bulky pipelines, radiators, boilers.

However, quite often on the Internet you can find information about the dangers of infrared radiation and the negative effects it has on the human body. Such myths have no scientific basis.

Radiant heating benefits from the fact that it evenly warms the room without creating zones of “stagnation” of warm masses

On the contrary, in this sense they are “more useful” than other common heating methods, because:

• do not dry out the air or burn out the air;
• do not raise dust, since there is no convection;
• keep the body in good shape due to the slight temperature contrast.

In addition, such heaters are even recommended for people suffering from joint diseases, since they warm up the human body well, as a result of which inflammation and pain soon go away.

When long-wave infrared rays hit the skin, its receptors are irritated, to which the hypothalamus reacts, the smooth muscles of the blood vessels relax, as a result of which they expand.

Thus, IR rays help stimulate and improve blood circulation. Please note that they are completely harmless to the skin, unlike UV rays, which can even cause pigmentation changes. If you approach the use of IR radiation rationally, it will be difficult to find shortcomings.

Infrared heating panels are not harmful to health. On the contrary, they help cure joint diseases, and it’s not for nothing that they are used in medicine

In cases of poor quality maintenance and negligent use of devices, the following not very pleasant consequences are possible:

1. If installed incorrectly, the space will warm up in a different area that would need to be treated first. Infrared radiation is characterized by a clearly limited segment of action.
2. An infrared heating system does not always fit harmoniously into the surrounding space.
3. Excessive radiation can negatively affect electronics (TV, computer and other electrical appliances). However, it all depends on whether operating standards are met and what dimensions the room has.

Infrared panels are a new generation heating system. It provides safe and efficient home heating with minimal financial costs. You will not encounter any significant drawbacks when installing or using the panels, since they simply do not exist.

Smart Home control system

Automatic devices of the Smart Home complex can make a huge contribution to saving energy resources used to generate heat.

The maximum level of efficiency can be achieved by choosing a system equipped with a number of additional functions, namely:

• weather-dependent control;
• temperature sensor installed indoors;
• the possibility of external control with the provided data exchange;
• contour priority.

Let's take a closer look at all of the above benefits.

Weather-dependent temperature control in the house involves adjusting the heating level of the coolant depending on the outside temperature. If it's frosty outside, the water in the radiator will be slightly hotter than usual. At the same time, with warming, heating will be less intense.

The absence of such a function often leads to an excessive increase in air temperature in the rooms. This not only leads to excessive energy consumption, but is also not very comfortable for the inhabitants of the house.

Touch control panels provide the ability to select an energy-saving mode option, which allows you to quickly and easily adjust the temperature in the house

Most of these devices have two modes: “summer” and “winter”. When using the first, all heating circuits are turned off, leaving only devices intended for year-round use, for example, heating a swimming pool, to function.

A room temperature sensor is needed not only to monitor the maintenance of an automatically set temperature. As a rule, this device is combined with a regulator, which allows you to increase or decrease the heating if necessary.

An external temperature sensor is an indispensable component of most Smart Home control units. Such devices must be installed indoors, and if heat is supplied floor by floor, then on each floor

The thermostat can be programmed to reduce the temperature in the rooms during certain hours, for example, when the occupants of the house go to work, which contributes to significant savings in heating costs.

Priority of heating circuits during simultaneous operation of various devices. So, when the boiler is turned on, the control unit disconnects auxiliary circuits and other devices from the heat supply.

Thanks to this, the power of the boiler room is reduced, which allows reducing fuel costs, as well as evenly distributing the load over a given period of time.

A climate control system that connects the control of air conditioning, heating, power supply, and ventilation into a single network not only increases comfort in the home and minimizes the risk of emergency situations, but also saves energy.

Climate control drives, which regulate all functions of maintaining temperature parameters in the room, are usually hidden from view, for example, placed in a manifold cabinet

External control - the ability to transfer data to smartphones allows owners to monitor the situation in order to quickly make adjustments if necessary. One such solution is a GSM module for a heating boiler.

PLEN is a worthy alternative

Film radiant electric heaters are one of the most interesting developments in the field of energy-saving heating technologies. PLEN systems are economical, efficient and quite capable of replacing traditional types of heating. The heaters are placed in a special heat-resistant film. PLEN is mounted on the ceiling.

The film radiant electric heater is a complete structure consisting of power cables, heaters, a foil screen and high-strength film

The principle of operation of such a system

Infrared radiation heats the floor and objects in the rooms, and they, in turn, give off heat to the air. Thus, the floor and furniture also play the role of additional heaters. Due to this, the heating system consumes less electricity and produces maximum results.

Automation is responsible for maintaining the desired temperature - temperature sensors and a thermostat. The systems are electrical and fireproof, do not dry out the indoor air, and operate silently. Since heating occurs primarily by radiation and to a lesser extent by convection, PLENs do not contribute to the spread of dust. The systems are very hygienic.

Another important advantage is the absence of the release of toxic combustion products. The systems do not require special care, are harmless to human health, and do not poison the environment. With ceiling infrared heating, the warmest zone is at the level of the legs and torso of a person, which allows you to achieve the most comfortable temperature regime. The service life of the system can be 50 years.

An infrared heater does approximately 10% of the work of heating a room. 90% comes from the floor and large furniture. They accumulate and release heat, thus becoming part of the heating system

What makes PLEN so profitable?

The buyer incurs the greatest expenses at the time of purchasing a film heater. The design is easy to install, and if desired, you can install it yourself. This allows you to save on workers. The system does not require maintenance. Its design is simple, therefore durable and reliable. It pays for itself in about 2 years and can serve for decades.

Its biggest advantage is significant savings on electricity. The heater quickly warms up the room and then simply maintains the set temperature. If necessary, it can be easily removed and mounted in another room, which is very convenient and beneficial in case of moving.

Infrared radiation has a positive effect on human health and activates the body's defenses. By installing PLEN, the owner of the house, in addition to heating, additionally receives a real physiotherapy room

Heat pumps of two types

These designs are very popular. The device is considered the most efficient heating option because it is environmentally friendly. There is a type of heat pump called “mini-split”. It has an outdoor unit and one or more indoor units that supply both hot and cold air. There are two types of models on sale:

1. Air source heat pumps. These are structures that have devices that, even at -20 degrees, take heat from external air masses and distribute it throughout the house through installed air ducts.
2. Geothermal heat pumps. Devices with which you can use the energy of the soil. In the ground they are laid horizontally in rings at a depth of 1.5 meters, no less (freezing of the soil should be taken into account). Pumps can be installed vertically. For this purpose, wells are drilled to a depth of 200 m.

Although they run on electricity, the devices are energy efficient. Considering the costs, their efficiency is very high (1:3 for air, 1:4 for geothermal structures).

In addition, the units are environmentally friendly and absolutely safe. Another advantage of heat pumps is that they operate in reverse mode. They not only heat, but also cool the air. A geothermal device can be combined with a water heater, which will supply water up to +60 degrees.

Wood heating

Wood has long been widely used for heating houses: it is a renewable resource available to the population. It is not necessary to use full-fledged trees; you can also heat the room with wood waste: brushwood, branches, shavings. For such fuel, there are wood-burning stoves - a prefabricated structure made of cast iron or a welded one made of steel. True, such devices have negative characteristics that prevent their widespread use:

1. The least environmentally friendly heaters. When fuel burns, toxic substances are released in large quantities.
2. Firewood preparation is required.
3. Burnt ash needs to be cleaned.
4. The most fire-hazardous heaters. If you do not know how to clean chimneys, a fire may occur.
5. The room in which the stove is installed is heated, and in other rooms the air remains cool for a long time.

When choosing a wood-burning stove, you should pay attention to an efficient modern model that is equipped with a device - a catalytic converter. It burns unburned liquids and gases, thereby increasing the efficiency of the unit and reducing the emission of harmful substances.

Selection rules

Using such devices is a more efficient way to heat your own home. But you need to know how to choose the right equipment. First of all, you need to decide for what purpose the device will be used.

If you need a model that will be the main source of heating, then first of all you should pay attention to power. It is desirable that the device have at least 100 W/sq.m. If in a city apartment the ceiling height is more than 3.5 m, then you need to focus on the norm of 120-130 W/sq. m.

You should approach the choice of panels more carefully, based on your needs

There are other factors that may influence the selection of an infrared heating device:

1. Walls in the room. Their type, as well as the presence of insulation structures on their surface.
2. Glazing quality. It matters here what type of windows are installed in the openings, how effectively the sashes are pressed against the frame, and whether the products contain energy-saving glass.
3. Ceiling characteristics. What is the condition of the ceiling, what is located on top - another apartment or a roof.

All these factors have a significant impact on heat loss in the room.

Heat recovery

Using heat recovery will be a step towards creating an energy-efficient private home, as well as a good way to save on utilities. Heat recovery is the return of warm air using a ventilation system. When ventilating, we not only let in cold air, but also let out warm air, thus discrediting the central heating system, and we throw money away.

During recovery, not only the temperature regime is maintained, but the air is also purified. Every modern “passive” private house has a heat recovery system. Organizing recovery is inexpensive, especially compared to the benefits it brings. Statistics show that about 40% of the heat goes outside during ventilation. But you have already paid for this warmth!

So, there are many different energy-saving heating systems and the main question is how to choose the most optimal one. To do this, you need to devote time and effort to its selection, purchase and installation.

Conclusion

A heating system based on infrared thermal panels is the optimal solution for all types of health centers. This is the additional value that can be offered to the customer, lower installation and heating costs, better and healthier well-being. Long infrared waves help improve the circulatory system, strengthen the immune system, have a positive effect on rheumatoid arthritis, increase the stretch of collagen tissue, reduce joint stiffness and reduce muscle spasms.
