I have a mid efficency furnace that is mainly backup but whatever...here is my question.
does fan speed reduce stack tempatures on a regular gas furnace and if so would you get more out of your furnace if you ran a higher fan speed??
I know that you take more heat out of the water when you run a faster fan speed on a hydronic system so does this effect a gas fired furnace as well????
6 local shops have no idea what I mean and they say no .
I also think that a gas furnace should have a very low stack temp as there is nothing in gas exaust that would plug an exchanger like cresote would so you should be exchanging till there is not heat left I would think??
