In my house the ground floor (not basement) heater zone is freezing and pipes are breaking. Apparently this is because we run the wood-stove, and it keeps the thermal sensor high so the boiler won't run. As a result it's freezing the pipes. I am probably never going to do this (or be allowed to), but would it ever be possible to splice in a timer circuit, to active the boiler every now and again to stop the freezing? What is the typical electrical layout of this system? (all out of curiousity)
PS: It's controlled via thermostat
