Excessive heating is just like setting fire to five pound notes. Who wouldn't want to avoid that if they had the choice ?
For me there are balance points between switching the heating on fully and having it off.
It has got colder in the last few days so now using the gas fire and heated throw on the bed. Much cheaper than whole house central heating, which I only really use when it gets very cold, mainly in Dec, Jan and Feb to mostly stop the pipes freezing.
