I agree, unhook the hoses and I use a Thermo-cube from Tractor supply and plug in a "My heat" from Walmart. The cube plugs into a 110 outlet and cuts on at 35* and off at 45*, the heater is 200 watts Ceramic and is safe. I have a thermometer sensor in my wet bay that can be read from inside the MH. Couple days ago it was 27* outside and 45* inside the bay. Works great.
