Central Boiler Classic Edge Wood Furnaces

Central Boiler Classic Edge Wood Furnace Overview

The Central Boiler Classic Edge is an outdoor wood gasification furnace available in three models with a water capacity ranging from 150 gallons to 330 gallons. The unit has a vertical heat exchanger, which provides optimal heat transfer and allows exhaust particles to drop to the bottom, reducing the need for maintenance. It also has an air charge tube, unique to Central Boiler, which improves efficiency and lowers emissions by controlling airflow while preventing coals from falling into the lower chamber. Air-tight, waterproof urethane spray foam insulation and an insulated chimney help lock in heat and reduce wood usage, and the FireStar II electronic controller automatically adjusts the primary and secondary air to optimize the gasification process.

The 2016 starting price of the Central Boiler Classic Edge is $6,490.

"Nothing but junk!"

1.0 rating
Very Unsatisfied

The local dealer swore up and down in 2015 that the edge classic 750 was top of the line. This thing has been nothing but trouble since we got it! Will never stay lit whatsoever. Even after cleaning it like it's supposed to be. Contacted dealer and he swears theres nothing wrong with it. It doesn't get enough air to it at all. We will never own another one ever!


"problems with cleaning and keeping air chambers open"

1.0 rating
Very Unsatisfied

the first ce550 models were updated the following year after I purchased mine.. the way it was originally constructed made it extremely difficult and time consuming to keep the ashes out of the air chamber. In the middle of winter i have to shut down the stove, let it cool down, and then take the floor out in order to remove the rear panels, allowing me to clean the air chambers. This is only done by climbing into the door opening. This takes me 5 to 6 hours to complete. The updated version has a rear door opening to clean the air chambers. CE calls my stove "low maintenance!" Why does central boiler refuse to provide a reasonable upgrade when their engineers made such a grievous mistake?

It is 0 degrees f at 9 pm on January 30, 2019. I have just come back inside from once again trying to remedy the fact that my new-in-October Classic Edge 550 $12000 (installed) wood boiler is once again not heating its water enough to keep my oil boiler from firing up. This unit, purported to be adequate to heat a much larger house, consistently fails to adequately burn wood that has been seasoned 2 years and kept in a dry shed. The dealer is apparently not competent to service it keeps offering possible reasons for the lack of functionality. After several air and timing adjustments, after keeping religiously to the cleaning requirements, and using wood as prescribed, there can be only one answer; this product is awful, and Central Boiler has no customer service, no quality concern, and a poor product. Keep your conventional furnace or boiler. This product is Garbage.

The central boiler should e ashamed of themselves for putting a product like my 750 edge classic.!! I am a disabled veteran with a limited income and have close to $13,000 invested in a stove and piping that was supposed to be able to heat my house and pole barn with plenty of BTU's to spare! not!!!! Works great when it is 50 degrees outside as soon as it gets cold I can't keep my water temperature up. I go through tons of wood (yes seasoned and dry). I have to shut it down to disassemble the firebox to clean where the worthless chains are supposed to keep clear (which I shake at least twice a day). I've called the company 3 times only to treated like an incompetent idiot and give their old faithful lack of insulation speech! Just man up and admit you have designed built and sold a piece of junk!!! Which is why you no longer sell this model!!!

"Very Efficient Furnace"

***Learning curve to this unit*** 750 is very efficient and easy to use. This is the first wood boiler that I've owned. That must be the reason I can effectively use it better than the guys with the older units. I can see where they would have trouble learning the gasser units. Its a little more than cutting a log and burning green or junk wood. The wood for this unit has to be seasoned for it to operate correctly, I cut my wood a year beforehand to start drying. Very minimal wood used compared to the older units I've seen. All the old timers need to find one of these units and watch someone operate before writing it off. These only smoke very little when loading wood. Once the reaction chamber gets hot it will burn the smoke completely. I keep a good coal bed, run the cleaning rod thru the bottom 5-6 times and never have any trouble with fire restarting during the night. If you read the instructions on these units, it will operate exactly how it needs to perform.

Other Classic Edge Reviews

A post on hearth.com from a homeowner asking for opinions about the Classic Edge found many replies from people with complaints about the unit, including how to clean it. Most of these people, however, have only seen it and do not own one. On arboristsite.com, a member who saw a display of the Classic Edge said it looked like a good unit. Replies included another member who'd seen a display at a fair and agreed that the unit seemed good, but again there were no comments from anyone who actually owned one.
