I have a 600 sf basement and have had 2 frozen pipe problems over the past several years.. I intend to make this a heated basement.. and want a heating solution that can both heat the space as a living space and provide a minimum amount of heat when I'm not there to prevent freezing pipes... Can anyone recommend a heating source that is safe, economical and can be used with a thermostat that has a low set point for when I'm not there. I current have a 220 line available and propane nearby already supplying an upstairs heater.. Cost (of the actual heater and fuel consumption) is my most important consideration for the basement heating solution.

Thanks,

HR

current have a 220 line available

Baseboard electric heat will work well and cheap to install.
