Selection of Thermostats

Control and Regulation

Use a good quality room thermostat, preferably an electronic proportional thermostat with a integral timer to provide consistent temperatures and increased comfort.

For storage heating systems, more advanced control systems, which regulate the amount of energy stored by means of thermostats and/or outdoor thermostat sensors may be required.

Thermostat regulation: The thermostat will automatically control the comfort temperature, since the required heat is influenced by factors such as outdoor temperature and wind. The system will also utilize the so-called “free heating” from electrical appliances, lighting, the sun or persons. This “free heating” may make up to 10 - 20% of the heating required.

Selection of limitation sensor: For certain conditions, it may be necessary to use a thermostat that includes a limitation sensor for control of minimum or maximum temperature. > Consult Britech

Save up to 25% with setback temperature:

During weekdays, there may only be need for comfort heating during the morning and then again from the late afternoon to the end of the night. In office rooms, the comfort heating is normally needed during the day from Monday through Friday. Up to 15 - 25% of energy costs may be saved if the comfort temperature is lowered by approximately 5 C at night and during the day on weekends. The setback temperature has its greatest advantage in thin (10-20 mm) floor constructions and in wooden floors. Heavy constructions (40 - 60 mm) will have a higher heating capacity and therefore the time for lowering or rising of the temperature will be longer.

Installation of floor sensor: The correct installation of the sensors is required for the function of the thermostat and thereby for the comfort and energy consumption of the installation. The floor sensor must be installed in a section of the floor where there is a high probability that it will not be covered by heavy furniture. The sensor must not be placed close to the heating cable. If necessary the sensor cable can be extended up to 100 m with a standard installation cable.

Installation of thermostat with built-in room sensor: A thermostat with room sensor should be installed about 1.6 m above floor level. The sensor must NOT be installed on cold external walls, exposed to draught, direct sunlight or heat from various appliances. If a correct installation is impossible, a remote room sensor should be used. Then, a floor heating thermostat must be used, where the floor sensor is replaced by a remote room sensor.
