A plate heat exchanger provides a means to pass heat from one system to the other without having to actually join the two systems.

Since the tubes won't hold any pressure or load of any measure, other than their own weight and what ever low fan pressure to move the air, I am thinking 6010 or 6011 as they are fast freeze, 7014 would have a cleaner bead appearance.It is easily attached on the chimney pipe without the need of extra connectors, and the unique design increases the heat exchanging area without. We promote the EFFICIENT, RESPONSIBLE, CLEAN and SAFE use of all fuels, whether renewable or fossil. I have been pondering the idea of adding one of these HX's to my homemade boiler that I have been using for 3 years now. Or is there a chance with this design that I can actually extract more heat from the wood than a proper wood stove? Once the core is secured in place, I applied a bead high temperature fireplace mortar to all of the welded seams.

I got a pretty good sized fire going, nice and hot, to "cure" all of the fireplace mortar and stove paint. Ive spent some ammount of time looking for some kind of 'retro-fit' exchanger to fit on a flue, but havent found anything yet. i was going to fit one on those back boilers to my garden heater but it will boil the water unless there are sufficient radiators to heat soak!

I am not sure if there is a coating I can put on the pipes to prevent that, but I am not sure if it is worth it. Hello, I have heard of heating systems that recover some of the heat from the chimney of your woodburner and duct it around the house. Tapering down the exhaust ports through the heat exchanger to a single port that meshes with the flue would be a ton easier.

The down side to the multiple exhaust ports tapering to 1 is the possibility of turbulence restricting draw. I was able to measure up from the table to the brackets to verify that both sides were equal distance.If I make it easy to do then it shouldn't ever get built up bad enough to become difficult to scrape. Made 60 gallons of hot water in 20 minutes, enough for a few guys to take tub baths and do load of dishes with some to spare. But as the others have said, unless you want your chimney to rain, knock off the MacGyver routine and invest in a new system.

When I am up north I've gone through 3 chains on a trip, all skip chains for a 24" bar, but I have 5 and another regular chain set for a 20" bar.If you pull all the heat out of the waste gas, then you need some other method of getting moving the air through the system. Again I fastened the core into place with a series of tack welds, trying my best not to burn through the thin metal on the bucket. I used tin snips to cut out the opening, trimming carefully to try and make to hole just large enough to allow the union to fit as tight as possible. It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". I have no illusions that this will be a long-lasting stove, or high efficiency, however it is certainly fun to build and so far cheap.
