The diesel heater exhaust pipe is inserted to 1 inch copper tube (28 mm plumbing copper tube) and extend about 5 meters, Pipe heat up and add heat to the cabin, making it more efficient. The pipe in the ceiling is angle downward so water from condensation will flow out to the end by gravity.
I have used the diesel heater as it consume 30 watt of electricity during runtime, so will not add load to the house electric supply. Ordinary electric heater will consume around 2500 watts, 10 amps and as not good as the diesel heater. Cabin size is 32x10 ft, insulated. Simple solution to recover the heat from the exhaust
