16 KW Chinese diesel water heater

So here's my current setup utilizing a 16 kw Chinese diesel engine block preheater. This whole idea came about after the -14 degrees lows we were having last winter and the smaller 5kw heater not being able to warm the cabin up fast enough after work. this system is able to warm the place up much faster and is far more convenient with the addition of a smart thermostat which i can switch on an hour before returning home. the fuel usage isnt that much either.
