The majority of heating systems have at least two controls,a time clock or programmer and a room thermostat. In fact this is the minimum level of electrical controls specified by the Building regulations.
Time Clock or Programmer
This operates the heating system to turn on for set periods. This can either be mounted in the boiler or positioned elsewhere in the property. It will take at least 30 minutes for your home to reach the desired temperature, all depending on insulation levels and outside temperature.
This controls the air temperature which will switch the boiler off. The object is to switch the boiler off as quick and as long as possible and this will not happen unless you have a room thermostat. Wireless types are available thus saving running any cables or causing disruption.
Wireless Programmable Room Thermostats
This system allows you to programme the temperature levels to alter according to different times of the day and works on radio frequency so it can be positioned any where in the property up to 30 metres from the boiler.
Thermostatic Radiator Valves (TRV’S)
These allow you to control the temperature of each room individually be sensing the air temperature in that room.
