I bought this radiant heat 10,000 BTU model over the convection heat 23,000 BTU model for several reasons. The main one being smaller profile and cabinet style. This allows you to put it back towards a wall with the front facing outward rather than the center of a room. Setting up out the box is super easy and takes about 5 minutes. No adjustments were needed and it worked flawlessly out of the box. It came with batteries for the electric start and a siphon for adding fuel. I love the fact that the fuel storage container comes out of the heater, this allows refueling without taking the whole heater outside (#1 feature). I run it in a 20ftx20ft garage and that appears to be the max size i would use it for considering its 10,000 BTU's. It burns perfectly with no fumes and a clean blue flame (I use clear 1K kerosene). The price of this unit is excellent and I would recommend to anyone as an excellent purchase.
