I have gas central heating and a battery powered wall timer/thermostat. I'm not sure how to set the timings on the thermostat - it's basically set so that the heating is on 24 hours according to that, but we just turn our radiators on or off at the valve as needed.
Would this effect our heating bills, or is the heating/boiler only in use when we have the radiator valves open and in use?
