How we tested
Each heater was positioned at the same point on the floor. The floor was marked at 12 inch intervals up to 12 feet. This should provide enough distance to replicate use in most home garages and small workshops. Each unit was then switched on and left to reach maximum operating output in accordance with instructions. Using a piece of cardboard as a heat absorbing barrier, and an infra-red temperature gun, readings were taken after 15 seconds of continuous exposure. This was done at each 12 inch interval to loosely monitor the effectiveness of the fanned heat output. On the day of the test the outside temperature was 8 C, and the ambient workshop temperature was 14 C.
