The Hotpod stove went off valiantly to the test lab for some official testing. Everyone knew it was an efficient stove, but not that it's efficiency was more than a match for its looks. The Hotpod stove ran at 81.6% efficiency burning wood and had a very low particulate emissions figure. To be able to burn wood in a smoke control area in the UK a stove has to emit less than 6.9g/hr of particulates. The Hotpod got a figure of 0.7g/hr, almost 10 times less than the required fgure for a Defra Exempt stove!
