Multifuel Furnace is rated 4.0 out of 5 by 3.
Rated 5 out of 5 by from exactly what we needed Purchased this last year, wish I had done so years sooner. We have an all electric house with no access to natural gas, after incurring a $1200.00 electric bill in december of last year I purchased and installed this model. Seen mixed reviews on it but made the leap. This has been the best purchase I have made for my home. The following electric bill after having this in for the entire month was back down to the $275 range. I live in central Ohio and last year was a bad winter. We did burn a lot of pellets, approx $360 worth for the month so we still seen a big savings, over$500 for the month. The only draw back that I know of on this unit is getting the burn rate down. It is set high from the factory and at the lowest setting our house still sits at around 82 degrees. You have to call USSC to have them walk you through getting it set. We had did this last year but it still needs reduced. My house is approx 2800sf and three levels including the basement where the unit is placed. Walk out Basement gets VERY warm! Would purchase again. Have seen reviews about being noisy? May be if it were in the same room but as far as I am concerned it isn't bad at all. I tied into my existing return duct work for my furnace so my whole house fan will pull in the heat and push through the house since my fan is much larger that the fan this unit is equipped with. My existing unit is a five ton heat pump to give you an idea. Hope this helps and good luck beating old man winter!

Rated 3 out of 5 by from MultiFuel Furnace does the minimum 2nd year with the furnace. Hopper is very poorly designed and will not feed all 240# pellets. No Igniter, no external thermostat support. Agree with other reviewer, burns too much fuel. Noisy! lots of heat radiated from unit sides. needs bigger chimney than 3".for efficiency. No point having a 240# hopper if you cannot burn all 240# because all the fuel wont feed without user intervention. How can you produce a furnace without an igniter or remote thermostat? This thing costs an arm and a leg, though it burns fairly efficiently, all the efficiency is lost because of the reasons mentioned above. This product is likely best used in a shop or large garage for these reasons, and not someones home. It would be too loud for that, so it may be better to build this unit to be installed outdoors and designed to have air plumbed into the structure. This unit lacks in many areas and the poor description fails to warn the user of these pitfalls.

Rated 4 out of 5 by from like but part have to replace every yr. we bought the 8500 two yrs ago and like it but have had to replace the cast agitator 3x's now I'm ordering again and another $100.00 plus bill. we keep the dial on one and only once did we go to two. It heats nice and sometimes too much. we used wood stoves in the past and this is so much easier than cutting wood.. but need to get better cast or steel part. any ideas get a person that can do cast weld???
