Very nice unit - Easy to use, and easy to install. Some of the bits and pieces provided with the unit, is a bit in the cheap end. Example the tightening bands for exhaust etc. But anyway, this is a fantastic purchase, for a price, almost unreal.
The heater is doing a sublime job, heating my 30 m3, partially insolated, workshop to 25 degrees, also on the coldest days. The unit have the best economy, when it runs continuously, not having to warm up the workshop, every time it's turned on. When left running, it can sustain the room temp, with a ridiculously low daily diesel consumption. I have had this unit running on a liter of diesel for seven days. Of course, it depends on the outside temperature. I have purchased a power supply for the heater, strong enough to supply two of these heaters in case, and it just work perfect.
