Hello everyone
I installed the 200 mm exhaust pipe over the weekend and fired it up.
The draw was instant. The paper I put in to light the fire was drawing towards the riser. I lit it for an hour and in that hour the water temperature went from 35 C to 55 C. I filled up the feeder 4 times with roughly 2 cm X 3 cm sticks. Not densely, I could have fit more.
The only problem I had was that I measured 200 C at the top inside of the exhaust pipe. This seems like a lot of heat energy to be losing out on. I'm thinking of blocking off the exhaust pipe inside the barrel at the top to prevent the heat from shortcutting from the riser, but I'm not sure. What do you think?
Other than that the 4 cm rockwool is doing a great job. I stopped the fire at 1430 yesterday and this morning it was 50 C ambient temperature is around 18 C .
Next I will connect it to my underfloor heating.
