Normally if I was on holiday for 2 weeks at Christmas I would switch
the heating off and turn the water off just in case.
With very cold weather predicted I just wonder if it would be advisable
to leave the heating on the programmer but turn the thermostat down a
bit. As I see it if it still freezes I am stuffed so I might aswell
switch the heating and water off.
What do other people do?
