I've never seen a stove turned into a boiler before.. Wow :D

Honestly I would have never guessed that the flue temp is less with coal than wood...with coal giving off more Btu's than wood...and I was very concerned with going inside the stove period...esp with copper...and I know stainless doesn't have near the heat transfer as copper....and steam explosion was a big concern also...so I will carry on and see how it does and maybe do more if I'm not satisfied with this change :-)

I definitely appreciate everyones input and suggestions !!!!

You would use one of those inline thingies (pressure release valve), as lightning says...it would at that point be a mini boiler for short $$$. with coal your stove pipe is going to decrease by at LEAST 50% (where as over the firebed you would notice magic happen and an INCREASE of at least 50% over your wood burning flu pipe!) and it would be maintained, steady, easy long term heat (not a "rush by" of hot air out the chimney but rather an enveloping/encapsulating steady heat around the coil itself) :clap:

With wood, a bigger portion of the heat generated goes up the chimney.. With coal, the heat stays in the stove longer so it has more opportunity to become usable extracted heat into the home, or in your case stove-boiler :D

I hope you have emergency pressure relievers somewhere on the system :shock:

Please be careful.....

And, tee-ing in an expansion tank would help with the pressure swings in the pipes. The tanks are small and not expensive.

DITTO what lightning said....pressure relief valves are a MUST !

....if you lost power (or your pump failed)...you risk overheating the water in your system!
...great project..!

I fixed my post above :lol: I was impressed to see this per WIKI :

Copper has a thermal conductivity of 231 Btu/(hr-ft-F). This is higher than all other metals except silver, a precious metal. Copper has a 60% better thermal conductivity rating than aluminium and a 3,000% better rating than stainless steel.[12]

Thermal conductivity (Btu/(hr-ft-F)
Silver 247.87
Copper 231
Gold 183
Aluminium 136
Yellow brass 69.33
Cast iron 46.33
Stainless steel 8.1

Does this mean that Copper will heat water 30 times faster than Stainless Steel in a hot water coil application?? Uh, I'm having trouble with that hahaha.. Engineers please advise..

AND WHY wouldn't boilers be made of alloys of these other metals... :|

I never tried this but watched a lot of youtube videos on copper coils being put around and inside flue pipes. Keep the arrangement with the water heater and place a coil of copper tubing around the flue pipe. That will increase the surface area for heating the water and you don't have to be concerned about the coil catching any creosote when you burn wood or fly ash when you burn coal. Check out the link below.

I didn't get A great pic but you can kinda see the blow off valve in the pic labeled "outlet" I posted this morn...nd I forgot bout posting the other pic of pump and all so here it is...boiler expansion tank, auto air bleeder, backflow prevented, pressure reducer/ quick fill, and valves

I applaud your efforts but,........ The baseboard radiation will not work in reverse as your attempting. you would be better served to put as many rows of pipe under the vessel and use it for dwh preheat. If your just tinkering ,great ,but if you want to get serious about heating your house with coal ;get a coal boiler (preferably a stoker) and use your fin tube baseboards or a coil in your ac ducts. I dont mean to be critical ,just trying to illuminate reality :surrender: :D

It does preheat my domestic hot water 2 via this indirect fired hot water to the left of my electric hot water heater...and I am mostly screwing around but also trying to heat the house...in a diff way...its more of a learning project and an experiment to see if I can make it work

Yeah man, a lot can be learned from a little self indulgence in experimentation 8-)

Hmmm, where did that water electrolysis separator go? Those hydrogen flashes were cool :lol:
