Heating Controls

The heating and hot system controls are quite basic in most older houses, leading to huge inefficiencies in their use.

Controls include:

• Room thermostats in the house
• TRVs (Thermostatic Radiator Valves)
• Cylinder Thermostat (the hot water cylinder will turn off when it reaches a certain temperature)
• Boiler Interlock (the boiler turns off when the house reaches a set temperature)
• Programmer (to heat the house and hot water at specific times during the day)
• Zone control (where there are separate zoned areas which can be controlled independently)

In older houses improvements can be made by installing a room thermostat, boiler interlock and some TRVs on radiators. A cylinder thermostat and programmer can also be installed.

Using the boiler exclusively as the means to produce hot water for the house also reduces the energy used significantly.

Newer houses should have time and temperature zone control which requires plumbing different areas of the house on different loops, enabling thes areas to be controlled independently.
