My thermostat is in the hall and that's the coldest place in the house so I pay no mind to it. The heating is off now as I'm in debt to the fuel company and not wanting to use the heating unless absolutely necessary. We are using hot water bottles at night, minimising using the oven, the hot water is only on for an hour a day, I've got thermal curtains over the draughty front door and patio door and when the heating was being used I had half the radiators switched off.
I've ordered some room thermometers to see just how cold the main rooms are when we are complaining it's cold. If you have them, what is the temperature in your living room and bedrooms?
