I just wonder with all these boilers out there and the ones people build why dont more use outside air for combustion?
The high efficency oil boilers use outside air.
I built a wood boiler 2 years ago used outside air wworks good[not gasifier] The one I built this year is Gasifier and I pre heat the air before it goes in combustion it seems to work very good. I know you cannot send cold air in chamber and try to keep Temp. up, But it seems a waist to be buring warm inside air up from house.
The outside boilers use the cold air to rum why not in the house?
Is there something I am missing???
