Away during cold spell - frostfree setting on boiler??

[Gentleness]

Dh looked at the manual and decided to set the boiler on the frostfree setting while we are away for a week. I left it to him and now am freaking a bit - we don't have room thermostats - just individual ones on the radiators, so how on earth does it know when to come on! Family in the same area (Birmingham suburbs) have had a burst pipe, but they left the boiler completely off.

Can anyone reassure me or am I facing disaster when we get back - on a flippin' saturday - typical!

Not too sure but it sounds as if you are talking about a froststat setting? This is there to protect the actual boiler not pipes/radiators around the house. To protect from burst pipes leave the heating on low. I could be wrong, have not heard of a frostfree setting myself so hopefully it is a constant low temp across the whole house.

Lesson from this - double check dh's ideas! I so hope we do not got back to a mess...
