When using thermal panels, hot air accumulates under the ceiling less intensively than when using convectors. Therefore, thermal walls are especially effective in heating the halls of cottages, the lower tiers of two-story apartments, as well as other rooms with high ceilings. Due to the low intensity of convective air currents- the main carriers of house dust- these devices can be used where allergy sufferers live.
Thermal panels allow, if necessary, to reduce the temperature in the room by 1–2
Thermal panel Fantazja (Instal Projekt) is perfect for high-tech interiors. Its front surface is decorated with a perforated steel screen. There are four steel towel holders. The device can heat various rooms and dry wet textiles
Electric thermal panels heat the room by converting electricity into heat. ATthey are most often used in a city apartment in addition to an existing central heating system. They provide a comfortable temperature in autumn and spring (when the supply of hot coolant to the batteries has not yet begun or has already been completed, while it is cool outside), as well as in winter, in severe frosts, if the power of central heating radiators is not enough. Appliances in a splash-proof housing allow you to quickly warm up the bathroom. Some models of electric thermal panels can be installed in children’s rooms, since their surface temperature does not exceed 40
FROMwith the help of thermal panels it is possible to provide the main heating of a country house. It is logical to do this where there are no interruptions in the supply of electricity (or they happen extremely rarely) and a sufficiently powerful cable is connected to the building. Most often, however, they are used to heat rarely used premises, to which it is economically or technically impractical to conduct pipes with coolant from the boiler room. The key to successful adaptation of electric thermal panels to a specific room- the presence of wiring in it, designed to connect powerful electrical appliances. No additional thermostatic devices most often need to be purchased- panels are sold with a built-in thermostat, which provides temperature control in the range of 5–30

European manufacturers produce electric thermal panels in the form of small rectangular plates mounted on walls. The case, which has a box-shaped design, is made of sheet steel, covered with white powder paint. Inside, a nichrome thread is laid on the heat insulator, which evenly warms up the front surface of the device. The power of domestic panels is 100–700Tue Dimensions- 500
Imported panels are often made of glass. So, perhaps the first thermal panels that appeared in EU,- products of the Safir series (Nobo, Norway). Their body consists of two glass plates connected to each other. Between them is a thin electrically conductive layer that generates heat when current passes through it. Safir panels are produced for horizontal and vertical installation. Instrument length- 1400mm, height- 400, 500 or 600mm, and power- 750, 900 and 1110W respectively. Price- 13–210 $. for 1 piece Appliances with a front glass surface for living rooms, bedrooms, kitchens and bathrooms are manufactured by Fondis (France, Solaris trademark). The capacity of Solaris products is 450‑1500Tue Height and width vary within 450‑1500mm. Models are available for vertical and horizontal installation. The cost of devices is approximately 35–600 $. for 1 piece
Cinier (France) electric thermal panels made of Olycale stone look impressive. Each panel is handcrafted at the firm’s factory and decorated with Egyptian, Greek or African sculptures. The customer can choose any of ten stone colors and eight tones of enamel coating for painting the panel surfaces. For decoration use ceramics, chrome-plated metal, colored glass. The devices are equipped with a double-insulated heating cable and a thermostat that receives signals from a sensor built into the panel and maintains the temperature of the stone at a safe level. The height of these products - 1200–2200mm, width- 400–800mm, body thickness- around 30mm. Thermal power of one of the models (2000
ATelectric thermal panels, which are a hybrid of a radiator and a convector, are also on sale. For example, electric heaters of the Verlys Evolution series (Noirot, France) are equipped with two heating elements that transfer heat into the room in the form of infrared radiation and through convection. Convective heat exchange takes place between the air entering the case and the RX Silence Plus mono-metal heating element, and the outer thermal panel emits IR radiation. An electronic thermostat controls the two heating elements. Thermal power of devices- 0.75–2 kW. Instrument length- 600, 800 and 1000mm, body thickness- 75mm, height- 480mm. Price- 12.5–18.90 $. for 1 piece
Finally, many heaters designed to work in water heating systems can also be turned into electric thermal panels. To do this, it is necessary to mount a special heating element (electric cartridge) into one of the panel collectors and fill it with propylene glycol or another non-freezing liquid so that the surface of the heater is evenly heated.
So, for example, Karowatt KW thermal panels (
Water thermal panels heat up due to contact with the heat carrier of the heating system or with hot water from the DHW system. It is expedient to use these devices for the main heating, and also as heated towel rails. ATIn the latter case, devices equipped with shelves, hooks for towels and textiles, etc. are chosen. Almost all commercially available models are equipped with thermostats. Water thermal panels are supplied (however, as well as electric ones) complete with fasteners- brackets, plugs andt.P.
ATautonomous heating systems of cottages water thermal panels are usually introduced without problems and “live” in them for a long time, regularly transferring the heat produced in the boiler room to the house. BUTtheir “symbiosis” with the heating and hot water systems of typical high-rise buildings, alas, too often turns out to be short-lived. Models made of thin-walled (thickness 1–1.5mm) pipes made of low-alloy steel and aluminum. Premature deterioration of the panels occurs due to corrosion caused by the contact of their internal surfaces with an oxygen-saturated coolant or hot water from the DHW system, as well as due to pressure surges. To increase the service life, thermal panels in such cases are connected through an “intermediary”- a two-circuit adapter (it is also called an intermediate heat exchanger). A device of this type has been developed and manufactured, for example, by the Time company (TBEK series) together with KZTO (both- Europe).
The domestic market for water thermal panels mainly offers products from foreign manufacturers that produce devices of various designs. The most widely represented in EU are thermal panels made of rectangular metal pipes installed close to each other and welded to the coolant collectors. Most of these devices are designed for operating pressures up to 4–5 atm, so you have to connect them to the heating system of a city apartment through an adapter. There may, however, be exceptions to this rule. For example, a company
The front surface of thermal panels of the Nova Mirror series (Zehnder, Germany) is also formed by flat pipes (section- 70
How does an intermediate heat exchanger work?
Hot water of the heating system or hot water circulates along the internal contour of the double-circuit adapter, and along the external one (in addition to the heat exchanger, it includes the piping and the thermal panel itself)- antifreeze or water. Naturally, water from the heating system or hot water supply and the coolant from the secondary circuit do not mix with each other, but only exchange heat. Circulation in the outer circuit of the adapter- gravity or pumping (the coolant “drives in a circle” the circulation pump built into the circuit). The adapter provides a fairly quick heating of the panel to operating temperature. The latter, however, due to heat losses will be 5–15
The intermediate heat exchanger is cut into the mains of the heating or hot water system or connected to it in parallel. In this case, you can not be afraid of high pressure testing, the presence of oxygen in the water, hydraulic shock andt.e. The inner circuit pipe is very durable and easy to descale or replace. It is permissible to use any pipes in the external circuit- plastic, metal-plastic, copper andetc. Even if the supply pipe of the thermal panel bursts, there will be no flood- the volume of the coolant in the external circuit of the system is only a few liters. This, of course, is not the cubic meters of hot water that are thrown into the apartment when a device built into the heating or hot water system is destroyed.
Some manufacturers decorate the surface of tubular thermal panels with metal sheets (most often- of stainless steel). This technical solution organically fits into high-tech interiors. For example, for Credo-Techno (Kermi, Germany) radiators, a flat front panel covers two rows of pipes and all connecting fittings. The perforated screen made of polished high-alloy steel is a design element and can also be used for hanging towels and other bath accessories in the bathroom and living areas. Height of thermal panels Credo-Techno- 1400–1800mm, width- 540–690mm, depth- 122 or 133mm. The cost of appliances- 44–700 $. for 1 piece
ATsale you can find very spectacular thermal panels made of stone (more precisely, stone chips, gypsum andt.etc.), inside which there is a copper or steel coil for the coolant. Due to their large mass and low surface temperature, these devices, like European stoves, fill the house with soft and comfortable warmth.

Cinier, in addition to the already mentioned electric thermal panels, also produces devices for water heating systems. Their heat exchanger, made of copper pipes, according to the manufacturers, has sufficiently high anti-corrosion and “anti-expansion” properties, which ensures high reliability and long service life of the heaters. Instrument working pressure- 5 atm. The cost of water thermal panels Cinier is 70–1300$. for 1 piece
