Central Boiler Classic Wood Furnaces

Central Boiler Classic Wood Furnace Overview

The Central Boiler Classic is a wood furnace available in four models, with a tank capacity ranging from 140 gallons to 764 gallons. It features a ripple top design for increased heat transfer area and a vent cap designed to eliminate evaporation. The unit's large, insulated cast iron door is designed for easy loading and maximum efficiency, with a powder coating for increased paint durability. A water-filled HeatLock baffle will not warp or burn out, and sprayed-on urethane foam insulation forms an airtight seal around the water jacket. Due to the EPA's New Source Performance Standards, new Classic models will only be available until the end of 2015. Base models of the Classic start at $5,490, though prices can vary depending on shipping and options.

I called Central Boiler and of course they don't give you the time of day and tell you to call the dealer..BS The dealer only response was it would be cheaper to hire a welder than send the stove to there main office to get repaired.. The 25 year warranty is no good….

"No idea how much this furnace has save me"

5.0 rating
Very Satisfied

I started working for Central Boiler in 1991. At that time I was burning a wood stove indoors. So that fall I installed a cl 17. In 27 years I think I have replace the solenoid twice, other than that the furnace hasn't been touched, It is working flawless for me. I'm heating my home, detached garage and my hot water. I go through approximately 8 cord of wood a winter depending on the winter in northern Minnesota. When it comes to maintenance I make sure my water treatment is at the proper level and I clean my ashes completely out monthly. As a rule I fire twice a day, it makes it easier to stir the ashes. Can't get much easier than that. All those years ago when I purchase this furnace I never would have guessed it would have saved me this much money. Looking at the condition of the Firebox I see no reason why it won't last many more years.

"5 years now with a 5036"

5.0 rating
Very Satisfied

I've had my cb 5036 for 5 winters now, heating 4800 sq ft. I use mainly radiant with the optional heat exchanger for really cold nights. I've been absolutely amazed to find that I consistently burn only 6-7 cords per year, honestly. Regarding the stove, well I've done nothing to it other than maintain it…..water changes, water tests, burn offs and cleaning at end of burning season. I will add that i only fill the stove with soft water and recommended additive.

"Stay away from Central Boiler"

1.0 rating
Very Unsatisfied

Stay away from Central Boiler. Look into your purchase very carefully before putting significant dollars into one of these. Lots and lots of maintenance. The sales rep I have only makes sales. Not an installer; refers you to someone else. We had a stove rot out in less than 6 years. They want you to frequently check the nitrate levels of your water. I have no less than 3 neighbors who have these…they put in their original corrosion inhibitor and never checked their water. No problems. Their stoves are older than ours. Ours rusted through the water jacket. Think about boilers over the years (schools, hospitals, churches, etc) that never had any corrosion inhibitor–they lasted longer than 6 years with straight water in them. Considered strongly filing complaint in mn but would have to travel there to make case. This company is located very close to Canada border. Finally, worked out a "deal" where we paid for half of a new furnace (this is after less than 6 years), cost us $3900, we had to pay the shipping and go get the furnace from rep. The damper door constantly sticks and blows fuses–this is a brand new stove. We're told to adjust the damper throw (wouldn't you think this is handled at factory?); no one comes out to fix the brand new stove unless you pay someone–and, they're not even a rep of the company, these are independent guys. The warranty the push is worth very little–read what you must do. And, again, there are no service guys for this company; you have to ship your stove back if you have problems. Seek another company.

Other Classic Reviews

A homeowner on hearth.com was trying to choose between the Classic and a Heatmaster unit which was $2000 less. A couple of people said to get the Heatmaster because the price is so much lower, but a slight majority preferred the Classic because Central Boiler is a bigger company with more support. A homeowner on forestryforum.com deciding between the Classic and the E-Classic was told by most responders that the Classic is time-tested and that most customers have been satisfied with it.
