Not sure it’s sustaining itself at present, just allowing for bigger toys (don’t tell my wife!!) At the moment with 125mm heatproof flex pipe Brett for trial only but next week (or the week after) it will be flued properly up through the roof. And commissioned by a suitably qualified gas fitter. The shed it’s in has fully insulated walls and roof and is 6x4 Metres purpose built for roasting in (wish it was three times the size!) It has aircon to control the temp and a couple of exhaust fans for safety sake too. Sent from my iPhone using Tapatalk
