RADIANT HEATING

The warmth and comfort during the winter days are vitally important for every home, office, store, and that can be achieved easily with the radiant heating Therma-Ray. The technology was developed in Canada and is suitable for the harsh climate in the country. It utilizes conductors that carry a small current and create a magnetic field with a wavelength of 560 nanometers. This wavelength is characteristic for the sun rays when reaching earth's surface. Based on this phenomenon, only hard objects get heated, not the air.

With standard heating solutions, air forms a temperature gradient, where the most heated part climbs towards the ceiling, while the coolest goes down to the floor. With radiant technologies the heat is distributed uniformly creating more comfort in the room than with a standard heating solution - the temperature difference between the floor and the ceiling is only 1 degree centigrade.

The radiant heating Therma-Ray avoids the build up of dust because there is a low circulation of air. It works equally well when fitted in the ceiling or the floor.

The desired temperature is selected with a thermostat, which contains a piezo crystal that measures the temperature with accuracy within 1 degree centigrade. The temperature range is from 4 to 29 degrees centigrade. When used optimally, Therma-Ray uses twice less energy than standard home heating systems.

The heat radiated from the panels "automatically" goes where most needed and helps achieve a pleasant temperature.

The usage of electricity for heating with Therma-Ray is easily calculated the following way. For an example room of 4 by 5 meters, with a heat loss of 60 W per square meter, which is achieved with a 25 cm concrete wall thickness with 6 cm of thermo insulator Fibran:

4 m x 5 m x 0.06 KW/sq. m. = 1.2 KW
1.2 KW x 24 hours x 30 days x 6 months x 0.47 x price of electricity

where,
1.2 KW - the maximum heat supply - in the room
24 hours - for a day-night
30 days - the days in a month
6 months - the length of the season when heating is needed
0.47 - the coefficient of concurrency, which for Sofia is calculated the following way:


   Δt0         =     20° -  /+3°/     =    17°  =  0.472 
Δtmax              20° - /-16°/            36°  


in that formula:
20° - the temperature for comfort in the room
3° - the average temperate outside for the heating season in Sofia
- 16° - the lowest registered temperature in Sofia.

The average financial load for the 2004/2005 heating season with the current price of electricity is 1.435 BGN/month for a square meter.

The price of the installation fitted in that room is around 400 euro.

The heating system is embedded in gypsum panels. The panels vary in sizes and power, which allows for optimum solutions for every room. They are completely silent, harmless, don't dry the air, cannot cause fire and do not require special service.

The interior of the room is freed from the standard radiator - when furnishing you no longer have to take that into account.

Therma-Ray allows easy maintenance of cleanness and there is no danger of getting burnt. The low amount of dust and a hygiene environment are result of the minimum air circulation. The heating panels can be fitted under different types of flooring, with the exception of carpet and wooden parquet.

Fitted on the ceiling as a decorative panel, Therma-Ray can be an accent that completes the interior.

The fitting of the panels is quick and effective. The radiant heating THERMA-RAY is suitable for stores, restaurants, offices and dwellings.

Therma-Ray provides not only warmth, but also an always dry and clean floor during the winter. Any wet areas dry quickly and there are no hidden corners to build up dust and microorganisms.

The warranty of 40 years for the elements and 5 years for the thermo regulators provides confidence about the warmth and comfort in every house, office or store.
