We have a house in France but currently live in Australia. Having heating full stop is a new experience for us. When we were looking for a house in France it was after one of their coldest winters and a lot of expats who do not live in France permanently came back to burst pipes which worried me a lot when our house went through the first Winter.
I think some of the expats left water through their pipes - we drain ours.
We have noticed that it is costing 500 euro a year for 500 litres of fuel for the radiators and apparently it is suppose to just be on "defrost" however when we were there in Dec/Jan last/this year we noticed it kept kicking in even though it was 12 degrees or so outside.
We have a neighbour come and turn it on at the start of winter when it gets cold and then turns it off when the risk is gone.
If we just drained the pipes and did not have the heating turned on would we be ok? Would the radiators be ok? The guys across the road don't keep their heating on over winter they just drain the pipes but they do not have old fashion heaters either.
I am not sure if the radiators would freeze - would they if we did not turn the heating on?
We are just trying to suss out if we drain the pipes can we save money on heating or is it too much of a risk. Our house is in the Dordogne near Belves so it gets a bit cold but not -19 degree temperatures. I think the coldest I seen (monitoring it on my iphone) is about -4 degrees.
Any advice would be appreciated.
