Moved into our new home on Monday (its not a new house, 1970s built) but its quite cold. The previous owners moved out middle of last week so switched heating off. Friend of the wife said if we left central heating on all day at a medium temperature we would warm the bricks up and would mean the house will be warmer in the future, even after a day of not having heating on during the day.
Is that possible? How long do bricks and blocks retain heat for?
