We will be out of country for almost whole winter. I know we got to leave the furnace ON while we're away.
But what is the best temperature we should set on the control? We're in mid-west Canada. In winter, temperature could be below -30C (-22F). We have a gas furnace in basement where the water main comes in., all utilities are in the basement including water heater and softener.
Thanks,
John
I would shut off the water and drain it down no matter what you set the furnace at. Too much possibility for something to go wrong. Don't forget to turn off the hot water heater.

One insurance company I spoke to INSISTED the water system be drained if the house was vacant over the Winter. Mine doesn't, but I do it anwway ..its often -20 here during Dec/Jan. We set ours at 55oF as thats the lowest setting on our thermostat (heat pump VS gas furnace) and my heat (electric) bills only run about $ 60/mo. All our Ngas: water heater, cooktop and Gas F/P is shut off.
It would be cheaper to leave the furnace off and winterize your house plumbing.
Why do you have to leave the furnace on, I dont and it gets to -15f, I drain everything and winterize the traps, My setup with ball valves takes me 5 minutes and its all done. I also turn the water off at the street. Even leaving furnace on you need everything done, furnaces break and there are power outages, unless someone will visit every day you are at risk. A furnace is forced air, not radiators. If its left on a freeze alarm that calls you is a good idea. Why pay to heat when you are not there, plus you kill termites and other bugs.
