"Goes Days Without Refilling!"
We've been running our m175 for six years and have only good things to say. Other reviewers here may be confusing the category they're posting in so it's important to note this is a wood pellet furnace. The m175 (and newer m255 models) have a huge hopper on top that holds about 500 pounds of pellets at a time. When we start it in November and the temps are above 0, we only go through about one 40-lb bag of pellets a day. I make it part of my routine to go check it once a day which means lifting the hopper lid and maybe moving the pellets around with my hand (if the hopper if low, the pellets will naturally fall into the auger but they can bridge because the pellets tend to stay on the outside edges...gravity, go figure). If full, it can go several days without needing to add any more pellets. We have a 120-year old farm house and an attached 2-car garage and it never has a problem heating it all, plus we turn off our hot water heater and never run out of hot water (be sure to install a side arm heat exchanger on your water heater if you have an outdoor furnace!). I think it's important to burn only high-quality, premium pellets because the cheap ones do produce more ash. With good pellets, I take about a 5-gallon bucket of ash once every 2 weeks or so, meaning it burns extremely clean. Overall I'd highly recommend a Maxim!

"Popular for a reason"
I was a bit skeptical at first about the sorts of claims they make with regards to how well these units can heat your home, and how much money they'll save you overall, especially given their upfront cost and the alternative way of needing to fuel them. However, I've found that, over time, the heat provided by this furnace has been far better than any I've gotten from more traditional central heating elements and radiators. When properly fueled, it heats your house up incredibly quickly and seems to keep it warm without needing to refill it constantly, for a cost that ends up being far less than if you were relying on more traditional heating elements to do the job for you. Overall, I've been very satisfied with this unit, and would recommend it to anyone looking into making the swap to a more renewable energy source for their home, as well as an efficient heater in general.

I've had trouble since day one. The aerator burns off regularly and regularly plugs between the top screw and the feed screw. I wired in a switch to isolate them, but it shuts down regularly. Restart it and it will run all day just fine and will go out over night ( the furnace is off site from my home). Service is difficult to arrange; I have been told 3 weeks for a technician. I am an electrician so we get by. We are in the third year of operation and cant wait to replace it.

"Maxim Wood Boiler Review"
This wood burner was part of the house when we moved in. Overall, we are pretty satisfied with it. The burner keeps the home nice and toasty during the winter, which is when it gets used the most. Cleaning it is fairly simple, and so far we have had no problems with it. I would recommend the Maxim M175 to a homeowner who was looking for a new heater for their home. Purchasing wood pellets has turned out to be a cheaper means of heating our home than using a gas or electric heater. These savings are sure to satisfy anyone who might be interested in purchasing a wood burner.

"Working Warm During the Cold Midwestern Winter"
I have a big shed in my backyard that I do a lot of wood working out of. It started as a hobby and turned into a mini business. It's not lucrative, but I enjoy it. I used to do woodwork out of the big shed all year long, but the Midwestern winters are too nefarious sometimes. I gave up doing any work in the winters because of how uncomfortable and cold the barn can be. I decided to finance a Maxim outdoor furnace and use it to allow me an opportunity to work year round. The furnace is very efficient and heats the entire space. If anything, it sometimes gets too warm and toasty. I've never had any issues with the unit. It's still only a year and a half old, so I'm about to enter my second winter with it, but I don't foresee any issues with it. If anything, my only gripe is the price of the unit. The shed I use is quite large, so I needed a furnace that could handle its demands, but the unit did not come cheap. I'm unsure if it was worth the lofty price tag. I would definately reccomend the brand, but I might encourage someone to look for a better bargain.

"Outdoor Wood Furnace"
I bought my wood furnace over 5 years ago.comfortable heat. Since installing it I have not used any gas and the house is 72 degrees Wood is the most economical choice. The wood mode allows the user to operate the furnace burning only wood. Wood is a totally renewable resource that is beneficial for the environment because burning wood is natural. When burned, results in no net increases in carbon dioxide. On the other hand, fossil fuels when burned, release carbon dioxide which would otherwise be trapped in the earth. The burning of fossil fuels causes a net increase in carbon dioxide which is believed to be responsible for the heat trapping greenhouse effect. United States and Canada. Making this purchase was one of the best ones I have made and I would suggest it to anyone.
