Recently read advice from an insurance company that to prevent pipes bursting the central heating should be kept on all night. Is this really necessary? Our house is heated up to 10.30 at night and starts again at 06.30 in the morning and is occupied all winter. What are the changes of pipes bursting in such a situation?
Any advice appreciated
Who's to say in a particular house whether the night time temperature will go low enough for pipes to burst.
My Dad advised me to leave the attic hatch open about 10cm so heat from the house would rise into the attic and stop the temperature up there dropping low enough to freeze the pipes. The attic insulation is on the floor of the attic, so unless the hatch is ajar heat from the house wouldn't penetrate into the roof cavity where the pipes are. My house is very well insulatedso I only have the heat on for about 4 hours in the evenings and so far no frozen pipes. Touch wood!
If you leave the hatch open, all the warm air will condense in the loft, a lot of people last year including myself had the attic dripping with condension. Far better to put a heater up there, but this does contradict the fact that we are insulating to save energy.
Very little point in opening the hatch to the attic to allow heat in if the house isn't actually heated, as is clearly stated in the first post.

Actually the first post is about leaving the heating on all night as opposed to on in the evening and then again in the morning, so clearly house is heated.
