Corporate History

Columbia Boiler Co. was founded in 1936, when it designed and manufactured its first steam boiler, the Columbia Residential Steel Boiler. Since then, with the exception of a few wartime years when the company produced steel holding tanks and heat exchangers, the company has specialized in manufacturing quality and serviceable boilers for every possible application.

Product Lines


Many of Columbia’s products are specially designed for small installation spaces, and the company promotes the fact that it has boilers available to meet nearly every need. The company markets residential boilers under several series. The Emerald Series is a combination of hydronic and hot water heating, available in 11 models for various installation needs. The WB Wet Base is the company’s top-tier line, featuring a 3-pass horizontal tube design. The LV Low Mass series operates with a low volume, low standby loss scotch marine heat exchanger. The Casco Bay CBX is able to reach up to 87 percent thermal efficiency in part by recirculating the flue gasses through the boiler three times. The company also makes a cast iron boiler line, some of which reach up to 95 percent thermal efficiency.


Columbia Boiler Co. provides a limited lifetime warranty on all of its residential boilers.

"Leaking Junk"

1.0 rating
Very Unsatisfied

I'm a homeowner and rely on my tradesmen to supply a good product. Well, this product was a fail. In November of 2012 I decided to replace my 1943 oil-fired hot water boiler with a gas-fired. The old unit worked fine but fuel oil was almost $5 at the time with no sign of going down in cost (boy did I bet wrong!). About a month ago – late January 2015 – I noticed a puddle under the boiler. I called the plumber who put it in and it was determined that the block was leaking at a factory-sealed seam between two of the three cast-iron heat exchanger sections. Columbia won't cover the labor cost to repair or replace the defective boiler. So I'm stuck for another $1,500 after the $3,000 I paid in 2012. Moral of the story: make sure your service professional provides the warranty information prior to purchase and read the fine print.

"Colombia waste oil boiler tech service is worthless"

1.0 rating
Very Unsatisfied

I recently purchased a Colombia Waste Oil Boiler. From the first start up the stack temperature has exceeded 1000 degrees. I have provided the local representative and Colombia technical service all the readings they asked for. They are now asking for more readings and will not return my calls. They have no explanation for the high stack temperature. I also didn't mention the boiler cannot reach temperature, even with a bypass fully open. I would not recommend anyone buying anything from this company. It seems they don't back up their product.



"Columbia Boiler"

5.0 rating
Very Satisfied

We recently replaced an old Columbia L-Series boiler (which still worked wonderfully, it just wasn't up to safety standards, and was 41 years old), with a brand-new Columbia WL-Series boiler in our commercial building. It is now just over a year old, and we are extremely pleased with it. No problems to report so far. Overall, a solid, built-to-last boiler.
