[Equest-users] Boilers with/without Draft fans

[Omar Katanani]

Dear all,

I have a hot water boiler in my project. I tried simulating my project once with a draft fan for the boiler, and once without. 

I got a space heat. consumption of  814,600,000 for the case with a draft fan.
I got a space heat. consumption of 1082,000,000 for the case without a draft fan (natural draft).

Is it possible that the space heating consumption differs around 25% between both cases?!

Many thanks,
Omar
