"Polar G3"

5.0 rating
Very Satisfied

Very well built, easy to clean and maintain. I like the fact that the combustion chamber is under vacuum when burning, this prevents the door gasket from being filled with creosote, there is no smoke when I fill the unit. Prior to the g3 I was burning about 10 – 12 cords of wood to heat my 3500 square foot house, cellar and garage in Western ma. With the g3 I burn about 8 cords for the entire heating season from October through May. I clean out the ash about every 2 weeks and check the water chemistry twice per season. I top up the water at the start of the season but don't usually have to add any in between. This is a great unit!

"Fire box is way to small"

This wood furnace has positive things to it. Love the fan for the quick refire. However, the downside, and it's a big one is that you have to refill it way too often. It's tiring to have to fill it late at night then get up to refill every night. It heats our house fine and our hot water. But, it is tiring and frustrating. Especially when our old one would last for close to a day even in minus 40 temperatures.



"Great boiler!"

5.0 rating
Very Satisfied

I have had my g2 for four years and it works great. Very efficient and saves us about 3k in propane bills We use about 6-7 cords to heat 2300 sq ft early 19th century house in the mid-Atlantic region. I liked that the controls are simple and easy to adjust – no electronics to mess with. Very adjustable unit. I could not be more pleased!

What a great unit! Live in Yukon Territory, canada and already at -25 C. Polar Furnace delivers with ease on 2700sq/ft. Indoor boiler. Very efficient and easy to clean. I went with Polar because local dealer has one for himself. Good for installer = good for me! Smart. The craftsmanship of unit speaks to the overall quality. Dealer is known for high quality work as well so no surprise he sells this unit. I wonder if the poor reviews below are fake from a competitor with an Axe to grind because a better product I'd finally on the market. Seems odd given how well made these are. Anyway, 2 thumbs up from Northern Canada.

"Terrible unit / Terrible service"

1.0 rating
Very Unsatisfied

Please take my word and don't buy a Polar Furnace. It's a waste of money, time and energy. As mentioned in the other reviews the company "doesn't have any control of the vendors " so they basically don't get involved once you've paid for the unit. Vendors..we've been trying to get our vendor to come for the last six months and we still haven't seen him. Our unit is 4 years old and it has a water leak that is not reparable. Unlike what the company "guarantees " they don't come and repair if your unit has a leak. We hired our own mobile welder to soon find out that our unit is very cheaply made and that it's not reparable. On the company's website they recommend Polar Furnace for farm, business and etc… Well I certainly don't recommend it because it's not made to last and using it to heat large places will require more wear and tear and it doesn't last to the "guaranteed " quality – Im only using it to heat a single home and it's already broken after four years.
