I need your help with this one. I have built my first RMH using Ernie and Erica's 6" plans.
My heater works fine when it comes to lighting it, its draft if pretty amazing. The problem is that I don't get efficiencies nowhere near what many of you have reported. I burn more or less the same amount of wood to heat the room than I did before with the normal store-bought stove.
-I see smoke coming out of the chimney even after the system has been running for several hours.
-Outside barrel temperature rarely exceeds 350-400F when I use extremely thin pieces of wood and constantly play with it. Normal temperatures are more around 300F.
-The RMH fails to heat even a relatively small lounge (13' x 15') in a mild Welsh winter (Outside temperatures around 40-50F (5-10C).
I have included a link to video of the first lighting as well as photos showing the building progress.
I have used new refractory bricks, refractory cement, insulated everything with a clay-perline mix. Also used new stainless pipes for the exhaust. The heat riser is a piece of T304 stainless steel surrounded with a clay-perlite mix.

Looking forward to hearing your thoughts on this. I wish to be able to fix what's wrong with my RMH and start using it again.
