Boiler Question

We need to replace a boiler and have space and design limitations too detailed for this message. We've looked around and came across something called "boiler in a box" that is built to the specifications of the homeowner. If you guys don't know anything about it, its an idea that we'll toss in the pile of non options. I appreciate your response.

    boiler in a box`

    If your talking about what I think you are, the "boiler in a box" term refers to pre-packaged boilers and add on parts and controls that are pre-package to just "bolt" on and go. Viessmann does this with their mixing valves for radiant heat that come all assembled and ready to mount on the boiler and pre-wired to just plug into the control and away you go....Hope this helps.

    I think I'd stay away from the Dunkirk Q series boilers. I was kinda leary of a aluminum heat exchanger because all I could think about was Chevy Vega's. Besides a lot of ignitor problems, plastic induced blowers that went bad after a year, we removed about a half pound of aluminum chips from inside one unit that was having intermittant lockout problems. It was clogging condensate lines and closing the press. switch. Was told from the factory that this is typical of a 20 year boiler. Could this be the next Glow Core?
