Earth Bear Cub Wood Furnace Reviews

"Works great for me"

5.0 rating
Very Satisfied

I have a 1,400 square foot log home and heat with the Bear Cub. The hydro-stat came set at 155 on and 160 off. Once I learned to load it properly, I can run for about 12 hours per fill. Once it gets down to 0 to 10 F, I fill 3 times. I spend about $1,200 per year for wood. When I heat with propane, it's over $2,500. I thought I had a leak once, but it turned out to be moisture from the wood when the temp is up enough that the damper is closed and the fan is off longer. This is about the 6th or 7th year. I have read the negative reviews and do not agree with them. Sounds like they don't know how to arrange their wood and embers, or use too large of wood pieces.

We used this unit one year. It constantly overheated or blew cold. We followed their instructions to but constantly had problems. The second year (last year) it began leaking it seems like a weld busted but the manufacturer said it was probably the overflow valve because they break all the time! Read the warranty carefully because if you have a serious issue the only way they repair it is if you return it to them🙄😮. What's wrong with sending a repairman…especially since it's under warranty. I would definitely not recommend them!

"Never buy an Earth. They blame the customer for problems."

1.0 rating
Very Unsatisfied

Two winters old and unusable. The fire chamber has a large crack in the inferior (yes, inferior) steel. Nathan Kelly told me it is my fault because I built the fire too hot. Really! Isn't hot the idea? Then he said I didn't maintain it well enough. Still my fault. They are not responsible for repair. This is a $4500.00 investment. I took very good care of it. I don't like being blamed for the lack of quality of their furnace. Their advertisement made promises they will not keep. Nothing's under warranty. Of course it's written to protect the manufacturing company. I would not recommend an Earth Furnace to an enemy. There is no honor in offering something and making promises that are not kept.

"Don't Buy an Earth Furnace"

1.0 rating
Very Unsatisfied

I have a 1000 square foot house and this furnace will not keep the house warmer then 60 degrees. I also have to fill it 4 times a day with seasoned oak firewood.The Earth salesman told me I would only have to fill it once a day. I also noticed the fire went out constantly when set at the factory at 180 degrees.

"Bear Cub 305 FA – Dependable and a Great Value"

5.0 rating
Very Satisfied

I've owned my Bear Cub model for almost a year now. It is the perfect size for my small Alaskan cabin. I can activate the burn from a control switch in my house, the little furnace can generate as much heat as I need from it at the push of a button. It is super insulated and very efficient. Also, my wife wanted something that would match the cabin so the sides of the furnace have the appearance of log cabin, just like our actual cabin! She thinks it looks cute, and I don't mind myself. The only problem I've found with this model is that it seems to take abnormally long to generate sufficient heat when we empty it out and start from scratch. We have had it for 10 months and we have never had it repaired or worked on. So far, dependable and easy to maintain. I would certainly buy the same brand again. Earth Wood Furnaces did a great job with this product. I actually did recommend Earth to my brother in law, who has a larger home so he bough a larger model, but he was just as satisfied with the product. Overal, it is a big upfront cost, but one that is certainly worth it over time.
