What Gas Boilers Are Manufactured In The U.S.A.?

So, what gas boilers are actually manufactured in the United States? (And as an aside, do you prefer a certain manufacturer?)
Thanks all.

Are you talking cast-iron or mod-con? Except for Buderus, Vie$$mann and the various Biasi-based ones, most cast-iron ones I know of are made here.
Mod-cons are a different story. Now that Slant/Fin is gone, it's hard to tell what's made where- even with storied American brands like Weil-McLain or Burnham. You'll need to do some digging.All Steamed Up, Inc.

Thanks Steamhead. I was thinking of both cast-iron and mod-con actually. I want to keep my options open. Stinks to her that with mod-cons...it isn't often straight-forward as to where the boiler itself is manufactured.0

The only modcon boiler that I can think of that is fully manufactured in the US is Energy Kinetics Accel. Plus they have the best customer service along with the best tech support.9

If you don't see the American flag being proudly displayed, it's not American made.
It can be assembled in USA with foreign components at best without the flag. But it does create jobs.
If you went out of your way to be able to say Made in USA, making the sacrifices to be able to do so, you would be displaying the flag.

I doubt there is any boiler that is 100% made in the US.
Electronics, transformers, switches, relays, brass trim, gas valves even the wiring itself could be sourced off shore.
I think many of the casts iron blocks are still cast here for Weil McLain, US Boiler/ Burnham, Dunkirk, Utica, maybe Crown/ Velocity.Bob "hot rod" Rohr

The thing about mod/cons and the HX made by a big HX manufacturer is that the HX manufacturer has hundreds of thousands of HXs across the world in many boilers. That almost says more than one which is made in-house. It has it advantages as well as disadvantages.
When I worked in the automotive industry, outsourcing was sometimes a positive thing. Like when a manufacturer really couldn't make a decent automatic transmission..... then they would use a global source for their automatics and would be much better. Aisin, and ZF come to mind.
That said, I've used Weil McLain mod/cons as well as NTI which both use the popular AIC (Poland) made firetube HX. Very well made.Serving Northern Maine HVAC & Controls. I burn wood, it smells good!2 -
Triangle Tube is an American Co. in NJ that if famous for making heat exchangers. They were making mod/con boilers for quite a while. I think they still are but there is a line of theirs now named "Ideal" that are made in the UK. So...its a bit confusing. Here is another factoid: Viessmann is the largest boiler manufacturer in the world. I think they make very, very good equipment. Buderus is out of biz. Rolled into Bosch. I believe.0

I love this topic and of course I am a huge fan of American made.The heart of Energy Kinetics combination heat and hot water boilers, the pressure vessels, have always been manufactured in New Jersey from domestic steel and stainless steel from local mills. We design and build our steel spiral boilers (System 2000, Ascent Combi, Resolute) and unique stainless steel fire tube boilers (Accel CS) for a combination of the best performance, longevity, and field serviceability. We don’t over emphasize design for manufacturing, which makes others’ designs smaller and cheaper, but usually means much tighter flue passes and/or water passes which we feel reduces long-term dependability in American homes.Our Energy Manager controls are also made in the USA, which for some reason really surprises many people.
Overall, we always make our boilers from USA materials and components wherever possible, although going the extra mile takes more time and effort and can add to costs. We think it’s well worth the effort.Best,RogerPresident

Energy Kinetics might do good since they won't have a tariff fee.

True for many of their offerings, but there are some overseas models in every one of their lineups. The Cast Iron bread an butter boilers may be the Made in America products, but any of those ModCon boilers that they offer ans some of the DHW tanks were from Europe and Asia for years. I wish @Roger would chime in about the EK products. I kind of remember the Columbia Boilers have the Made in America label also

After you make that expensive repair and you still have the same problem, What will you check next?

Thank you all for your kind words about Energy Kinetics! I'm glad this topic came back around to Made in USA…
All of our boilers are Made in USA with steel and stainless steel from local mills. This includes our gas mod con lineup - I wasn't happy (understatement) with the Euro and Asian models that are heavily designed for manufacturing with tiny water passes and tiny flue passes that can foul and fail. Instead of building a boiler around a foreign pressure vessel, we invested heavily in R&D, development, automation, and robotics to design and manufacture our own pressure vessels in Lebanon, NJ. Has all that hard work payed off? The Accel CS has been on the market since 2013 and we have not had a single pressure vessel failure. They cost more, but are well worth it with long life, quiet operation, and extraordinary efficiency built on high performance, serviceable pressure vessels plus thermal purge for both heat and hot water. Our Sealix "non stick" coated plate heat exchangers are designed to make hot water while driving boiler return temperatures down between 80°F to 110°F, so condensate rains out in a heavy flow and keeps the fire tubes clean. Our Smart Boost means temperature reset can be set very aggressively and the supply temperature will automatically increase if a specific zone is on long enough to require some higher temperature help, techs don't need an engineering degree to set it for best performance and efficiency.
Of course our spiral pressure vessels used in the System 2000 Frontier/Resolute/Ascent models are also made from specially formulated steel from local mills as well. These are built for ease of service, and although we call them 30 year boilers, we have boilers still running from 46 years ago when the company was founded. We also go the extra mile with Made in USA components down to parts like Ward fittings cast in Pennsylvania, our Energy Manager (built to Mil Spec standards in the USA), insulation and refractory, powder coated sheet metal jackets, and more. We offer American Made burners, circulators, and safety controls as standard as well (some of these have a few sub components are sourced elsewhere).
We continue to innovate and build on our model of high efficiency, serviceable boilers that are made in USA. Working direct with installing contractors means we have faster feedback and clear intelligence on where we can improve over issues found with non-Energy Kinetics models, and I have to thank our network of high quality contractors, territory managers, and techs that help keep us more than one step ahead.
Best,
Roger

Did they see Dyatlov in there?

As to the proud label of products "Made in USA" is concerned, that ship sailed decades ago. I just read the making of the Ford F150 today relies on parts from 24 ( twenty four) different countries, for example. In recent posts about whether Maid-o-Mist and Hoffman vents where all made in USA , it only generated speculation, and Not a single post from a representative from these manufactures to confirm one way or the other. People raved about the low prices at Harbor Freight, and after going in and seeing everything was made outside the USA, I choose Not to buy a single thing and walked out - never to return.
I favor steam heat but keep reading on this site about new boilers failing with a fraction of the life span of older cast iron boilers. Just sayin
All the Best,

You must be an individual who has chosen to walk around naked…………to the rather unpleasant situation that you have placed all your neighbors. 😁

I emailed Jacobus and they responded that the Maid O Mist vents are indeed made in america

When you picture intelligent life on another planet (as far fetched as it seems), do you picture them working as a cohesive whole, or like us?

it’s not far-fetched, it’s practically a certainty. From ants to fish, to birds, to prairie dogs, to chimpanzees, to us, and certainly to beings in other solar systems there is certainly cooperation. And individuals.

Maid O Mist was acquired DiversiTech While not explicitly stated in all results, DiversiTech Corporation is widely known to have acquired Maid-O'-Mist. DiversiTech has manufacturing and distribution facilities in the U.S.
The "All" Factor: Companies often source components globally, and product lines can change, especially after acquisitions (Maid-O'-Mist is now owned by DiversiTech, which has global operations). There isn't readily available public information from Maid-O'-Mist or DiversiTech guaranteeing that 100% of every item carrying the Maid-O'-Mist name is exclusively manufactured in the USA.
Now in 2017 Permira, the global private equity firm, announced today that a company backed by the Permira funds has successfully completed the acquisition of DiversiTech,
November 17, 2021 – Permira, the global private equity firm, today announced that the Permira funds have agreed to sell DiversiTech, a market leading supplier of critical Heating, Ventilation, Air Conditioning/Refrigeration “HVAC/R” Parts, Supplies and Accessories, to Partners Group, a leading global private markets firm, for an enterprise value of $2.2 billion. Partners Group and management will be the largest investors going forward, with the Permira funds maintaining an ownership stake.
So When did you email them 🤣oh and where are they based ? Or is your Crystal Ball still out for repair 🔮🤭
And it's NOT Illinois 😚

Please excuse my skepticism:
I appreciate poster Pauls re-post of communication. However, I would prefer to see posted an actual signed, dated, address, and phone number email from Brian Salem confirming that "ALL components" involved in the manufacture and assembling of Maid-o-Mist / Jacobus are Made in USA. What I see posted is a cut & paste' In fact, ad a Notary Stamp to the document as well

This may be one case where Made in the USA doesn't hold water, if they truly are made here. "In ceteris parabus" (Latin: All other things being equal), they can't hold a candle to Gortons & Hoffmans.
Gorton & Hoffman's are working professionals choice. They are expensive, Made in USA and the best I have found. They perform & hold up the longest. We are all free to make our purchase choices.
Germany and Italy also make super high qaulity products too that I use. Mad Dog

haha made in USA is always better except for this one company. You guys really crack me up sometimes

I have no idea which one is better quality. I'd have to see real data to know and that data doesn't exist. You like yours and I like mine and he likes his it's all fine. I'm just not quite able to understand how everything from China is junk and everything from US and European countries can be good. It's almost like there is something different between them…I can't quite figure it out.
