Should have mentioned that. I do; it is a dually - detects propane as well. My sape is well enough insulated that I can turn it off once everything is warmed up and leave a small thermostatically controlled electric heater cycling. I don't know if it's imporatant but I avoid generating wood dust while the propane heater is lit; it is just for a quick startup heat boost. The propane heater is far too powerful to leave on for long - the place gets to sauna temperature PDQ!
