US Stove MH6 Miracle Heat 6-Inch Heat Reclaimer

So if you're like me, you've done research on this thing and you're probably going to get mostly negative feedback from woodburning enthusiests. Despite that, I decided I'd give it a try since I figured it would be an easy install and really not that expensive of a unit.I installed my first one about 8 years ago. The install took about an hour for my specific setup (see picture 1). Just cut the pipe and put it in. The difference was noticed on the first use. That thing really kicks out the heat and the only one more thrilled than me was my wife. I've had 2 now and they are super quiet. Not sure what may have been off on other reviews but under normal conditions the fan and motor are very quiet. Nothing more than your refrigerator compressor.Contrary to the instructions I put the damper BEFORE the exchanger because I'd rather have the buildup before the exchanger. My first unit ran for 8 years and I never removed it to clean it (I know... gasp!). I do clean the chimney annually and never got around to disassemling the setup. I also burn seasoned wood and rarily have any sort of creosote buildup at all except the top 12" of the chimney.A couple months ago, we lost power and in an attempt to keep the house warm, I overheated the exchanger and it messed up the bearings in the fan. Still worked great but was very loud during operation. So I bought a new one (definitely got my moneys worth for 8 years). When I removed the old unit (again after 8 years of not cleaning), it had minimal building up creosote (see pictures 2 & 3). I think the combination of burning seasoned wood keeping the exchanger close to the stove with the damper before, all factor into this. Don't get me wrong! I do recommend cleaning the exchanger and all pipes annually but wanted to share that this thing is not the "death trap" that the "experts" claim. If this is how it looks after 8 years of daily seasonal use, then I think it would take seconds to brush out each year.Second one was installed and is working just as the first did. Extremely happy with it and will never own a wood stove without one. If fact I'm going to install the old "loud motor" one in my rarely used garage wood stove.If you're hesitant to try... don't be. You will NOT regret it!

I like the look overall of this unit compared as it looks more modern than another brand I've been using for approximately 12 years. After about 2 weeks of use, the US Stove MH6 started making a slight noise that isn't real loud or annoying, but I'll have to wait and see if this problem gets worse over time.I had hoped to purchase the identical product I've had for the 12 years mentioned, but it seems they have nearly tripled in price so I opted for the US Stove MH6 for the price alone. For the most part it seems like a well built unit that turns on when the stove temperature reaches a certain point, and then off when the stove cools down a little.It has been my goal to have a "stacked" heat reclaiming system for some time since we experience very cold winters with periods of well below 0 temperatures for days in a row. I installed the US Stove MH6 on top of my existing heat reclaimer and this aspect works great. Between the 2 units working in tandem, it doesn't take long to heat our 2,500+ square foot home. Even going as far as having to open a window or two to balance the temperature better. We never had to do that with just one unit.As far as being easy to install, installing anything to do with stove pipe is never easy, but the process was pretty straightforward for me and I had our wood stove up and running within an hour. Just make sure you orient all the stove pipe in the correct direction for easiest fit. Fluted edge of stove pipe down, which matches the orientation on the US Stove MH6.I would highly recommend the US Stove MH6 for now and hopefully it will have the same lifespan our other heat reclaiming unit has. If you burn wood, this is a must have for better efficiency. 4 stars for the noise factor after a short two weeks of use.

The main thing I want to say about this heat exchanger is its longevity. I have had bad luck with cheap fan motors. I figured this item might last a season or two. It's been far better than that. The fan and thermostat are as reliable and trouble-free now as they were the day the unit arrived.

When we got this we thought wow this will really heat up nicely. We got new pipes and set it up in October. We had problems getting the fire going. We've burnt wood all our lives. It shouldn't be so difficult. The last few times the house filled with smoke. We took it off to see what was up. These photos are after just four months of it maybe going on for 20 total minutes the entire time. I'm so glad the fire never got because it would have burnt my home down. The last photo is the wood stove. We changed pipes again and left it off. The wood stove is burning like a champ now. Please do not buy these. They're so dangerous. I can still taste soot from the smoke filled house on Friday. We switched the pipe and took this out on Saturday. I'm finally getting over the headache from the smoke. Please don't get this. Maybe try the fans that go on top. But stay away from this to save your sanity and possibly life. We thought it was the woodstove. I will never use one of these again. Nor do I recommend them. My old wood stove lasted decades and the pipes were cleaned every few years. This is 4 months of use! Four MONTHS!!!!!

It works well glad we bought it. It really does work and it saves you with the amount of of wood you use is way less then before we installed it...

As others noted, it gets noisy but it works as described.

Works well

Hooked it up, moves heat but fan is loud, tried to get the fan quieter but seemed cheaply made then I was smelling burning plastic and I see something melting inside the unit. Never exceeded safe operating temp. Wouldn’t advise purchase
