Heating Control Systems

You may currently only have one switch to turn on the power to your boiler and the pump, however, with the evolution of the modern heating systems there are now a range of heating controls to make your central heating system more efficient.

It is now a requirement of the current Building Regulations that on all new and replacement heating systems using gas and oil as the fuel to have a minimum of the following five controls:

  • Full Programmer for heating and hot water – This allows the water to come on at specific times set by they building occupant. It allows the occupant to control the domestic hot water circuit and heating circuits independently.
  • Room Thermostats – This heats up as the rooms temperature increases and once it has reached the set temperature, an electrical contact in the thermostat is broken and the electrical supply to the pump is switched off. A thermostats is usually placed in a living room at a height of 1.5 metres avoiding draughts and direct sunlight, and where there is not additional heaters in the room such as an electric or gas fire. It is also essential that the thermostat is not placed in a room which has a TRV fitted to the radiator.
  • Cylinder Thermostat – This device is fitted to the side of the hot water cylinder, and is set by the installer to operate when the top of the cylinder reaches 60ºC and then the electrical contact is broken, which in turn switches off the electrical supply.
  • TRVs on all radiators – A thermostatic Radiator Valve is a self regulating valve fitted to radiators, and it controls the temperature of a room by regulating the flow of hot water to a radiator. A TRV should be fitted on every radiator except for the ones in a room with a room thermostat in.
  • Automatic bypass valve – This device is a valve fitted within the pipeline and which automatically opens to allow water to pass.
