Wood stove heat exchanger idea - question on finned tubing

[Scott_NH]

Hi All -

I searched the forums for any info on finding a manufacturer of small finned tubing (like the copper / aluminum element used in hot water baseboard but smaller). I'm looking for element that is roughly 1 1/2" x 1 1/2".

Any chance anyone has seen this used or know of a source to get it?

I've been working on a plan to extract heat from my wood stove and transfer it to other areas of the house. If there is interest - I can reply to this post with a full break-down of the plan.....you guys could probably give me some pointers based on your experience.

Thanks,

Scott

What's to be the working fluid going through your tubes...air, water, other? Rick

I think John Gulland has a section for DHW on woodheat.org. It's probably worth a read.

I hear wheels turning

My Mom had a coal stove here in the house in the 70's. It was a big porcelin covered, cast iron beast. Firebox to the left, oven in the middle bread warmer to the right. 6 grids for cooking. AND it had a hook up on the side to heat hot water, if needed. I don't know how much it could heat, but I figure it was alot, because that stove kept 1500 sq of this house warm all winter, from November - April. I'm talking tank tops & shorts.

And would probably bake biscuits that were to die for. %-P

Yes, Sir, it absolutely did Strawberry jam (home made) is still my favorite !

It was great for bread, and roasts, too !

Plus laundry drying (rotating line hung up over the walls, which were 12', still are). Hang it up at night, dry by the morning.

I dont think you could heat enough water to heat a room or space .You would be better off blowing hot air.There is a heat sink on ebay that looks cool .I think it would be good to heat hot water for the sink or shower. I was thinking about hooking my stove to my hot water heater. I just run a fan in he room with the wood stove ant it moves the heat real good.

If there will be direct contact with flue gas I highly recommend a bare tube design instead of a finned tube.
