yes I use it. I have an aqua stat that will turn off and on the draft blowers. Works like a champ.
If I had an indoor furnace it too, would have a controlled draft.
I have a new fire chief indoor wood/coal furnace with a forced draft fan...It only works upon start up of new fire or when fire dies down and thermostate kicks it back on, Which is very rare due to the temp staying up in home...maybe as i run the furnace more i will get more use to it..Thanx, DW
