About this deal

It is easily attached on the chimney pipe without the need of extra connectors, and the unique design increases the heat exchanging area without. Air from outside of the stove pipe is forced through the heated tubes where it is warmed and then forced out into the room, literally reclaiming heat that otherwise would be lost out the chimney. These two books are the perfect starting place to help you get to grips with one of the most vitally important aspects of our society - our homes and living environment.

If you're not at close to 400° at chimney top, there isn't much more you can get without gumming up your flue in no time flat. I started a fire in my outdoor fire pit, poked some holes in the bottom of the bucket, and placed the bucket upside down on the fire.

The heat exchanger could connect into the existing CH system via a three port valve and pump controlled by a thermostat on the flue pipe (when hot, valve opens to allow log burner water to circulate around CH instead of combi boiler). It's old and was there when I bought the house so I have no idea how it was initially set up, my guess is not very well since there's no cap or anything on the end of the flue, the pipe just goes out through the wall and ends, also there is no filter on the oil feed.

I'm not sure from your description if your saying that your boiler vents directly out the side wall or vents into a chimney outside the wall. I can make a passably strong weld in dissimilar thicknesses, using the techniques you mentioned, but not a perfectly watertight one. I've been looking at stove paints etc and there are paints/coatings that are spec'd for direct flame applications. Remember that you really don't need (or want) to pull all that much additional heat out of your exhaust, so you don't need all that much surface area to do it.Read more about the condition New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging is applicable). Hilcoil sells stainless steel coils, not cheap however they might be a good idea if one was going to do a watertube heat exchanger that would last. Many boiler stoves available are still only rated for use on open vented systems, however a lot of heating systems are sealed or pressurised so you cannot simply join the pipes up. It's clean inside, I managed to get pretty much all the soot out of it as my first effort to get it wasting less heat, no idea how much better I made things since it being an old design, it's never going to be great (rated at .

Or will carbon steels that aren't low-hydrogen (let alone the weld metal), regardless of the coating, have accelerated rot due to the high temperatures? It's wise pre-planning to keep a big bucket of sand nearby to dump onto the fire in the fireplace/woodstove to smother it and prevent smoke from filling your house when you close the flue. Daily cleaning involves using the Soot Scraper knob to scrape the soot off the heat exchanger tubes several times during the day, In addition to scraping the tubes, burn paper or cardboard every other day to assisting with cleaning the tubes. These stainless steel coils are certainly a good option, but I am not sure how many I'd need to transfer a reasonable amount of heat, and that system might get expensive fast.half lives meaning they would start going off at random (often waking me up thinking there was a fire) and always when trying food. The main concern is the pipes hold together and are sealed so I'm not getting smoke blown in the room. Air pressure test at a low pressure - say 10 PSI - so I don't blow the thing to smithereens before it is finished, and use soapy water to find pinholes. If the fan is powerful enough you could do without the diverter flap, this would give a fail-safe feature too. 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.
