We have never had our heating on at night - it always went off around 9. DH decided to 're-program' the thermostat yesterday and set it to come on if the temperature drops below 17 during the night, with the result that the heating was on ALL night. It was far too hot for me so I opened the window, which he hates me doing as all the heat goes out of the window (I do agree with this, but it was so stuffy!). Also the pipes were creaking and making a noise all night and earplugs didn't help.
He has 'amended' it this morning, so we will see what happens tonight, but it set me thinking, do many of you have the heating on all night? It's something I have never done, except on the coldest of cold nights. I think it is an awful waste of money.
