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 Katanani
