Looking for a heater to keep my utility room pipes from freezing, either
electric or propane. It would be ideal to have a thermostat that went down
to around 35 or 40 degrees F. Other than that, I'll use a temperature
control to turn on power to an electric heater or a propane heater with
continuous electric start pilot light substitute.

Heat tapes would do the trick for the pipes but I don't want residual water
freezing in the washing machine pump. This doesn't freeze when it's 20
degrees F outside, but we had a pipe bust when it got to -9 degrees F.
We've had pipe freeze problems twice in the 10 years I've lived here so I'm
thinking it wouldn't take much heat to keep the room above freezing.

Anyone know of an electric or propane shop heaters that have a thermostat
that goes close to freezing temperature?
