Although it sounds counter intuitive, heating and boiler experts at Heatable are warning people not to turn off unused radiators to save money this winter as it may potentially drive-up heating bills.
Ben Price, founder of Heatable, explained: “Turning off your heating in unused rooms by turning the radiator’s thermostatic radiator valve to zero or off can save you energy, but it could also cost you more money because ultimately they’re always directly related. However, this largely depends on the age of your current boiler.
If your boiler is an old G-rated and non-condensing boiler (typically sold before 2005) you will likely save money by turning off unused radiators. But, if you have a modern condensing boiler - if you had your boiler installed after 2005 - they operate more efficiently at lower flow temperatures.
