Magic Heat Reclaimer?

Anyone have one of these in their single wall pipe? If it works, I think it'd be worth it. My shop stove has something similar and it works great.

According to your link it indicates it is for gas only, though the reviews have people using it on wood stoves. Should work, as long as there is enough draft for the byproducts of combustion (smoke and particulate) to keep flowing out. I would think the particulate from a wood stove might eventually be a problem...

The ones I've seen have a knob in the center that pulls a scraper plate over the heat exchange to clean off any junk that might build up.

I replaced a boiler where the owner had wrapped the chimney pipe with about 35 ft of 1/2" copper pipe as a preheater for his water heater. It was done so well I didn't have the heart to cut it out and left it on the new boiler.

Yes, I posted the first one I saw. They have models designated for wood stoves. That was my concern, when sweeping the chimney, wouldn't most of the creosote get caught between the tubes, thus plugging it up?

That would be a pretty neat feature. I'll look. Thanks!

Had one of those in the garage when I was growing up. They work great.

The gap between the pipes is huge so no real worry about it plugging up. Run the scraper more if you are burning the sappy wood.

yes, that's why they don't work on woodstoves. Even the ones supposedly designed for woodstoves will clog with creosote and cause dangerous chimney fires. If that happens and starts a fire, you can kiss your insurance goodbye.

They've been around for a long time, and if they were any good and not dangerous they would be built into every woodstove sold, but they're not for obvious reasons.

How much creasote are you talking about John? There is at least 1" between the heat exchanger pipes. There is a built in scraper to clean the heat exchanger pipes.

I would think a single wall tube pot belly stove would void the insurance.

Creosote in a chimney is normal, the longer the chimney, the more you get. It greatly depends on what wood you burn.

I've noticed that the only real buildup is near the very top of the doublewall pipe and on the cap. That's really about it. When I lift the pipe at the stove to vacuum out the scrapings, it's all really fine powder. I probably do this twice a year. Once before cold weather and once mid-winter (if possible). I'll check on the built in scraper, but that seems like it should work. Plus, only being 18-24" above the stove, it should be plenty hot right there.


John, it goes in the pipe above the woodstove, it isn't part of the woodstove.
