"I reduced my wood consumption by 55% when I switched (from a round barrel stove) to a Central Boiler Classic" - Jimmy F.










Advantages of a Central Boiler:

  • Proudly made in the USA in Greenbush, MN since 1986.  No social security # required
  • Burn up to 70% less wood!
  • Smoke less and are low maintenance
  • Able to economically heat multiple buildings, hot water, and pools with just one unit
  • Largest outdoor wood manufacturer in North America and #1 selling
  • There are Central Boilers in Wisconsin that are over 23 years old still going strong
  • No tubes to clean weekly for very low maintenance
  • Carbon steel firebox expands and contracts less than stainless steel prolonging firebox life by greatly reducing stress cracking of steel and welds
  • Stainless steel breaks down and cracks under heat stress
  • Carbon steel firebox transfers heat 50% more efficiently than stainless steel
  • High performance sprayed on urethane foam insulation outlasts and outperforms fiberglass batts
  • No matter how seasoned your wood is there is still a lot of moisture in it making the main firebox a wet environment, you want a flat easy to clean surface to prevent corrosion. 
  • There is no firebrick lining in the main firebox area, this improves heat transfer into the water and prevents moisture from getting trapped behind the bricks and rusting out the firebox.  Since you cannot see behind them you won’t know it’s rusting until it’s too late.
  • E-Classic models are able to achieve efficiencies up to 97% and do not smoke once started
  • Average outdoor wood furnace is only 30% efficient
  • Rear mounted chimney keeps hot gases from rising out the top like most of the competition
  • Chimney is out the rear instead of the top, simple physics dictates that hot air rises so putting a hole in the top of your firebox makes no sense whatsoever. 
  • Burning wood results in no net increase in CO2 helping to prevent global warming

Testimonials

“We love our outdoor wood burner!" Rated us 10 out of 10

- K&S Auto

“I think my Central Boiler is great! I only have to remove the ash a few times a winter. I was told that you burn a lot more wood when you go from an indoor to an outdoor, but when we put one in my son’s house he said he actually went through less wood with his Classic than with the indoor and it heated the house a lot more evenly.”

- Tim E. Bonduel, WI Owner of a Central Boiler for over 3 years that is still going strong.

My wife and I were excited we were building our first home and decided to put in an outdoor wood stove.  We had decided the Portage & Maine ML30 with a cost of $11,489.25.  Once the system was installed we had several problems, starting with the Portage & Maine fire went out constantly.  The dealer would not service it or come out and diagnose it.  The factory rep said it was a design flaw and a plate needed to be added to the bottom of the firebox but they wouldn’t cover the cost of it. This was only the first year of operation of the stove and we ended up burning close to 10 pulp cords of wood heating only 3,000 square feet for the season.
We had no other option than to replace it!

After doing research we had decided to go with the Central Boiler CL5036 with a cost of $6910.25.  The fire has never gone out, installation was professional and they cleaned up afterwards.  Any questions we have had Schulz’s have been right to help. The CL5036 burnt a lot less wood I would estimate we burnt 30% less wood with the Central Boiler the next year. I have not only recommended Central Boiler to several of my friends but also Schulz Heating & Cooling.  I’ll be a customer for life.

- Mike P. Gleason, WI

"The Central Boiler is the BEST furnace on the market as far as I am concerned, it burns complete. My brother Paul has one and he loves his too!"
Jimmy originally had a competitor's boiler and was trying to heat his shop with it, the competitor's boiler could not keep it at 60°F degrees when it was cold so he sent it back to the factory after weeks of arguing with them. After waiting several weeks for his stove to get back he finally asked if he could borrow one of our Central Boilers as it was now fall and was starting to get cold out. We gave him our demonstration model and hooked it up. After having the Central Boiler for a few weeks he took the new competitor's boiler and sold it and purchased the Central Boiler from us.

He could not heat his shop to 60°F with the competitor's boiler, while the Central Boiler heated his shop to wherever he wanted. He was excited to tell me after the first year he went through only about 24 face cords of wood. I asked him if that was good and he replied “well I went through more than 55 face cords with the competitor's boiler.” The competitor's boiler went through more than double the wood and would not even keep his shop warm. He then added his house and domestic hot water onto the Central Boiler and still went through less wood than the competitor's boiler did just trying to heat the shop.

"I would never buy a competitor's boiler in my life again, the Central burns all the wood up and has less ash, also the ash stays in the firebox and gives off heat still after the fire is out. Whoever built the Central Boiler knew what he was doing because it is efficient. It is the best furnace made as far as I am concerned. I used to go through probably 10 face cords or more of wood a year with the competitor's boiler, even after I added my in-floor, furnace, and domestic hot water in the house to the heat load, while heating my 3600 square foot shop which the competitor's boiler wouldn't even heat, the Central Boiler did it all and heated the shop to where I wanted it between 60°F and 65°F degrees." - Jimmy F. Antigo, WI Owner of a Central Boiler for over 13 years that is still going strong.
