Install Thermostatic Radiator Valves to control the individual temperature of my rooms

If you're throwing off the covers in the bedroom, just to keep the lounge warm then you should get Thermostatic Radiator Valves (TRVs) fitted. TRVs let you control the temperature of individual rooms, so each room can be it's optimal temperature and no more. They are easy to fit and save money from your heating bill - and you can sleep easier at night knowing that none of the rooms will be too hot.
