We went back to the UK for Christmas.
We drained the water completely and a neighbour came in every few days to check
all was ok. All pipes are very well lagged with fibreglass.
We only have wood burners, one upstairs and a wood burner/oven in the kitchen. No radiators with
them. When we bought the house there were electric radiators in every room, but they're very
expensive to run. Only if we run out of wood!
