I will be heating with a pellet stove for the first time this winter. I have three zones of heat in my house. One for the finished basement and One for each floor above. I placed the stove on the main floor to heat the top two floors. I used to just keep the boiler room door open in my basement and that would usually heat the basement to about 65 degrees without the zone ever coming on unless I raise the therm to 68. Since I will not be using my furnace for anything but hot water, what do you guys consider to be an appropriate temperature to keep the basement so I don't have to worry about the pipes freezing. The basement is about 1100 sqft of which 800 sqft is finished. Thanks for your help
