Here is a demonstration of the PT-70SS Diesel Radiant Heater from the Lavorwash Diesel Heater Range. This carry model has a heat output of 70,000 BTU (21Kw) which allows it to heat 175sqm. It has a tank capacity of 12 litres with a fuel usage rate of 2.0 l/h allowing a runtime of 6 hours on a full tank.
Being a Radiant heater, it is a lot more quieter than other fan-forced models. To see this model and more in greater detail, visit http://www.lavorwash.com.au/categories/diesel-heaters---space-heaters.html
