Burnham has been manufacturing boilers in the United States for over 150 years and remains one of the most recognized names in residential heating. Now part of U.S. Boiler Company, the Burnham lineup covers everything from high-efficiency condensing boilers to cast iron steam units and oil-fired systems. We install and service the full range across Nassau and Suffolk County.
Burnham boilers have a long history on Long Island. Many homes across Nassau and Suffolk County still have Burnham cast iron units in their basements that have been running reliably for 20 to 30 years. That kind of durability has earned the brand a loyal following among both homeowners and contractors in our area.
Today, Burnham operates under U.S. Boiler Company and continues to manufacture a wide range of residential boilers. The Alpine condensing series delivers 95% AFUE with modulating fire and outdoor temperature reset, making it one of the best options for homeowners looking to upgrade to high efficiency while keeping a floor-standing format. For homes with steam radiator systems, the Independence remains one of the most popular dedicated steam boilers on the market. And for oil-heated homes, the MPO-IQ offers 87% AFUE with an advanced IQ Control System.
We have been installing Burnham boilers since 1979 and are experienced with every model in their current lineup, as well as dozens of discontinued models that we regularly replace. Whether you need a simple like-for-like swap of a Series 2 cast iron unit or a full upgrade from oil to a high-efficiency Alpine, we can walk you through the options and help you choose the right fit. See our full brand comparison to explore all 11 manufacturers we carry.
Burnham boilers are manufactured in Lancaster, Pennsylvania. Domestic production means strong parts availability and responsive technical support when you need it.
One of the few brands with a current model for virtually every fuel type and distribution system. Gas, oil, steam, and hot water all covered.
The Alpine condensing series offers modulating fire, Sage 2.3 controls, and outdoor reset. ENERGY STAR certified and eligible for rebates.
The Series 2 and Independence use proven cast iron heat exchangers backed by a limited lifetime warranty. Built for Long Island conditions.
Available on the ESC and MPO-IQ series. Optional touchscreen display, low water cutoff, and outdoor reset for smarter operation and lower fuel consumption.
Industry-standard tapping locations on the Series 2 make it a direct drop-in replacement for many existing boilers. Minimal piping modification needed.
The average Burnham boiler installation on Long Island falls between $8,000 and $10,000 for a typical residential replacement. Cast iron models like the Series 2 and Independence tend to land on the lower end, while the Alpine condensing series may cost more due to the additional PVC venting and condensate drainage required.
Oil-fired MPO-IQ installations can vary depending on the condition of your existing oil supply line, tank, and chimney. If you are converting from oil to gas at the same time, that adds the cost of a gas line but eliminates ongoing oil delivery and tank maintenance expenses.
The Alpine condensing series (95% AFUE) qualifies for National Grid rebates and federal tax credits of up to $600, which can reduce your effective cost. We also offer flexible financing through Wisetack. For a full breakdown by system type, visit our cost guide.
If you open up the mechanical room in a 1970s or 1980s Long Island home, there is a good chance you will find a Burnham boiler in there. The brand has been a staple on the island for decades, and that long track record is why it remains one of our most frequently installed manufacturers. Parts are available at virtually every supply house in Nassau and Suffolk County, which matters when service is needed.
Burnham is not flashy. They do not make wall-hung units or Wi-Fi-connected combi boilers like Navien. What they do make are solid, well-engineered, American-made boilers that hold up year after year. The Alpine is their answer to the high-efficiency market, and it competes well against the Weil-McLain Evergreen and Buderus SSB in terms of performance and warranty coverage.
For homeowners who are converting from oil to gas, Burnham offers a particularly smooth transition. Many of our oil-to-gas conversion customers go from a Burnham MPO oil boiler to a Burnham Alpine or Series 2 gas unit, keeping the brand they already know while gaining significant efficiency improvements.
From the first phone call to your first warm morning, here is what to expect when you replace your boiler with a Burnham.
We evaluate your current system, calculate your heating load, and recommend the right Burnham model. We explain all rebates and financing options. No cost, no obligation.
Once you approve the estimate, we schedule at a time that works for you. We stock popular Burnham models and can typically schedule within days. Emergency service is also available.
Our crew removes your old boiler, installs the new Burnham unit, connects all piping and venting, and tests the system. Most residential installations are completed in one day. We clean up and haul away old equipment.
We register your warranty, submit rebate paperwork, walk you through the system, and provide tax credit documentation. We are here for any questions after the job.

Long Island homeowners share their experience with Burnham boiler installations by our team.
"Our old Burnham was 32 years old and still technically running, but the gas bills were brutal. Domino's replaced it with a Burnham Alpine and we saw the difference on the very first bill. They sized it correctly and the Sage control makes it run so efficiently. Great experience."
"We have a 1928 house with one-pipe steam and needed a new boiler. Domino's recommended the Burnham Independence and took extra care to size it for our radiator system. They even adjusted the near-boiler piping to improve steam distribution. No more banging pipes and the house heats evenly now."
"Converted from our old Burnham oil boiler to a gas Series 2. The whole process took about two weeks from estimate to final inspection, including the gas line work. Our heating costs dropped and we got rid of the oil tank. Domino's coordinated everything and kept us informed the entire time."
