I use the mr buddy heater off my regular propane sysem, quick conect hose to a fitting added under the stove top. Works great, ecconomical, have used it in a sob in wyoming at 10*. uses up oxigen so need to crack a vent. there is a vent sq. foot recomendation in the instructions. Dosn't work well above 6000' as the low oxigen senser cuts it off.
