Preventing heating pipes from freezing when using woodstove
I have a hot water heating pipe that runs through my garage against the ceiling. It has insulation on it and I never had a freezing problem. But this year with the new woodstove, I am concerned about it freezing due to not using the Oil boiler as much. Does anyone know if heat tapes could be used on a heating pipe, or just for water supply. Is there a pipe thermostat that I could put on the pipe to kick the heat on if the pipe reaches 35 deg?
