How to Connect a Chappee Coal Boiler as add on

PostBy: BWood On: Thu Oct 04, 2012 6:24 pm

Hello guys,
I just wrestled a Chappee Boiler 100,000 Btu boiler into the basement. I am going to add photos of my furnace and the new boiler. I can plumb just about anything with copper, but never touched a boiler. Any chances some one has photos of how they tied in their add on boiler?

I want the oil to step right in when I go deer hunting and the coal burns out.

I know how and would love to tell you but I am not a plumbing expert as you will find in here. But I will tell you that my old business partner in maine has on like that and it is fabulous at burning coal. Just wait and someone will come in and tell what you need to know. Welcome to the forum and enjoy that boiler.

BWood,It is time to get going on that Chappee.I don't think it is adequate for me to try to say in a few sentences how to do the boiler loops.There are different ways to do what you are asking.Your situation will determine the best practice.There are many pictures of well crafted piping configurations on this website to study.My advice is for you to get a book that describes the piping and wiring plus since there are safety issues the reason for doing it a certain way. In addition,nobody in this round world wants to do a piping job over again due to design faults when Jack Frost is at the window.Just my $.02 Mike

Here is one way: Plumb in a T in the return and supply header on your oil boiler, then connect those to the Chappee with a circulator. Return to return, supply to supply. The circulator will "grap" the cool water returning from the radiators, pass it through the coal boiler, and then back to the radiation. There will be some circulation through the oil boiler as well. You can simply turn down the aquastat on the oil boiler so it doesn't fire while the coal boiler is at operating temperature.

That's how I rigged it, I brought in an expert plumber who connects wood add on boilers. He recommended a three speed circulator, isolator valves for easy replacement and a cast iron radiator as a dump zone for power loss or run away heat.

I am still waiting to dewater and prepare final connect.
Thanks for all your help.

Hello All,
As always, i learned a lot here but nothing beats a pro. I found a great HVAC guy, he helped me set up the new coal boiler with a 3 speed circulator into the return line from the oil boiler, pumping towards the Chappee boiler, with isolator flanges for easy replacement. The supply runs out to the existing zone valves with a 1"T into the oil boiler supply. The caloristat controls the circulator on the coal boiler creating a thermal loop that keeps the oil boiler hot. When the thermostat calls for heat upstairs, the zone valves open and the heat runs upstairs. He placed a clamp on aquistat on the return to trigger a power closed special order zone valve located in a bypass loop that jumps the supply around the zone valves. In the event the coal boiler goes over 200 degrees, it opens the bypass loop which dumps the heat into the entire house. The valve also fails open in the event of a power loss, allowing the entire house to be heated in a power loss from the analog caloristat on the coal boiler.

Thanks for your help!

You better not lose that guy's phone number...his solution to your coal boiler is considerably more innovative than average.

How does the boiler run?

You need to gather just a little more knowledge before you are find yourself on the correct path -- and not mislead by misunderstood advice

Start here

Tell me what to know when designing a pipe system???
