Home Made / Re: Damper in flu pipe

« on: July 28, 2010, 08:36:24 PM »

I was just thinking when the boiler is cycling with the blower on there could be too much flow out of the stack. By putting a damper in the flu stack and a manometer just below the damper i would know what the flow rate thru the stack is .Therefore I could adjust the damper to get a flow rate just a hare on the positive side. I would adjust the damper so that there would not be too high of a flow rate which would waist heat. Just wondering if some of you guys do this.

Home Made / Damper in flu pipe

Hello everyone . I am new to the site and I am in the process of building my own boiler. I am wondering if any one has put a damper in the flu pipe . I will have a electric blower on the door. My design is very similar to the Hawken . Just curious if it makes a difference. Thanks
