Heating Advice
Is it more efficient to keep the central heating on 24 hours a day?
We are frequently asked this question and unfortunately cannot give a definitive answer as it depends on factors such as the age and construction of your house (older houses have poorer insulation and draughts, newer houses are generally quicker to warm up from cold), the design and efficiency of your heating system and the “comfort level” you and your family require.
In very general terms an older house with thicker walls but poorer insulation is slow to warm and may be best heated by constant use of the system at lower thermostat settings. A newer house, if it is quick to warm, may be OK with a timed heating approach as you suggest.
You already have two heating zones – and can therefore vary temperatures around the house. In addition you have thermostatic radiator valve and can change the settings on these to vary room temperatures as you wish, maintaining a lower temperature in rooms not being used. Assuming that you use these controls correctly then you are using your heating system very efficiently already!
