Thermostat Regulating
The principles of thermostat regulation of a floor heating system
|
|
| 1 |
The outer temperature gives a signal to the outdoor thermostat. |
| 2 |
This thermostat regulates the outgoing water temperature. |
| 3 |
The temperature in each room gives a signal to the room thermostat. |
| 4 |
The water circulation of each room is regulated separately through a solenoid valve, one for each circuit. Normally at least the bedrooms and living rooms are provided with a room thermostat | |
| Regulation values |
Approximate values for regulation are:
- With an outdoor temperature of 0°C, the outgoing water temperature is 26°C returning at approximately 24°C. The floor temperature is then approximately 23°C, which emits 22 W/m² into the room if the TAir is 21°C.
- With an outdoor temperature of -20°C, the outgoing water temperature is 32°C returning at approximately 26°C. The floor temperature is then approximately 28°C, which emits 77 W/m² into the room if the TAir is 21°C.
All values given above are unique for each building and subject to thorough assessment by the heating engineer. Big windows, high ceilings, windy sites, poor thermal insulation etc. will increase the heating capacity needs. The preset thermostat regulating the settings usually require altering once or twice the first time the heating is used. |
