Heating Controls for Boilers and Hot Water Cylinders
Using the heating controls correctly will improve the energy efficiency and reduce your running costs without affecting comfort. Central heating systems are fitted with a timer, room thermostat, and thermostatic radiator valves (TRVs) on each radiator.
Where the system has a hot water storage cylinder (not a combi) a cylinder thermostat will also be installed together with a motorised valve so that the boiler heats the cylinder only when required.
Combi heating controls are easier to set up and very often do not require wiring in as the programmable room stat connects directly to the boiler via a bluetooth connection.
