Burnham Commercial Boilers FAQ: Service, Installation, Hot Water Heaters and Ice Maker Cleaning

What This FAQ Covers

I’m a procurement manager for a 40-person mechanical company. I manage roughly $180,000 a year in HVAC and plumbing budgets, and I’ve spent about 8 years comparing equipment quotes, service contracts, and installation bids from 20+ vendors for Burnham commercial boilers. This is the FAQ I wish someone handed me before I made my first boiler purchase. It covers Burnham commercial boilers, service, installation, hot water heater integration, and why I also track ice maker cleaning in the same maintenance budget.

• Are Burnham commercial boilers worth the upfront price?
• What should a Burnham boiler service contract include?
• What does a Burnham boiler installation actually cost?
• Can a Burnham boiler supply a hot water heater?
• How long do Burnham boilers last?
• How to Clean Ice Maker Machine (and why it shows up in a boiler article)
• What is the biggest hidden cost in commercial boiler ownership?

1. Are Burnham commercial boilers worth the upfront price?

That depends on what you mean by price. The unit price is only the first line. Total cost of ownership (i.e., the boiler, delivery, startup, annual service, repairs, and lost heat if it fails) is the number that matters.

In 2023, I compared five quotes for a 2,000,000 BTU commercial boiler. Burnham was not the cheapest on paper. It was maybe $4,000 more than the lowest quote. But the low quote did not include startup supervision. It also had slower parts delivery. After I added two emergency service calls and a blower replacement, the low quote became the higher number. Burnham also gave us a warranty registration process that didn't require me to chase down a human being. The Burnham boiler was the cheaper decision, even though the invoice said otherwise.

My sample is about 30 commercial boiler purchases over 8 years, mostly for apartment buildings and small office complexes in the Northeast. If you are in a different climate or have very different water chemistry, your experience may differ.

2. What should a Burnham boiler service contract include?

You need more than a tag that says annual tune-up. For a commercial boiler, I expect the service contract to include combustion analysis, heat exchanger inspection, burner cleaning, safety control testing per ASME CSD-1, and a written report. If the contractor says they only inspect and clean, ask which parts are excluded.

In 2024, I got two quotes for the same Burnham boiler service. One was $1,800 and included igniter, gaskets, and a condensate neutralizer check. The other was $1,200 and excluded all parts and the neutralizer. Guess what happened after the first call? The $800 difference disappeared. Now I require an itemized service scope before signing. Look, I’m not trying to scare you. I just want you to compare the same service, not two different services that happen to use the same name.

Also ask whether the contractor tests the low water cutoff. Some annual contracts skip it, and that safety device is not optional in commercial buildings.

3. What does a Burnham boiler installation actually cost?

For a commercial replacement, I usually budget $15,000 to $40,000 for the full job, but the range is too wide to be useful without context. A small 500,000 BTU wall-hung condensing boiler is different from a large floor-standing cast iron boiler.

Why does this matter? Because I have seen a $27,000 quote turn into a $42,000 project. The base bid excluded the new flue liner, code upgrades, water treatment, and permitting. The $38,000 quote that included those items was actually the better deal. Here’s the thing: the lowest installation bid is only valid if it includes the same scope. I ask every contractor for a line item list and a list of assumptions. If anything says optional or not included, I add it to the comparison.

So glad I started using a TCO spreadsheet before signing installation contracts. Almost went with the low bid on a 2022 apartment boiler replacement, which would have required a $3,500 coring charge later. That saved us the difference.

4. Can a Burnham boiler supply a hot water heater?

Yes, if you mean an indirect hot water heater. A Burnham boiler can heat domestic water through a separate indirect storage tank. That setup is common in hotels, gyms, and restaurants, and it often beats a standalone hot water heater on operating cost.

In 2022, I helped spec a Burnham boiler with an indirect hot water heater for a 12-room inn. The tank added maybe $3,200 to the upfront project. The gas utility savings covered that premium in about three years, based on that building’s usage. Honestly, I’m not sure the payback will be the same in your area because utility rates change. But if you are already installing or servicing a boiler, an indirect hot water heater often makes more sense than adding a separate appliance with its own burner.

One maintenance point: the indirect tank still needs periodic flushing to remove sediment. It is not zero maintenance, but it is less equipment to maintain than a separate water heater.

5. How long do Burnham boilers last?

With regular burnham boiler service, a cast iron commercial Burnham boiler can run 20 to 25 years. A condensing stainless steel unit may be closer to 15 to 20 years, depending on water chemistry and cycling. But I don’t buy equipment based only on expected life. I track the annual repair cost for each boiler in my fleet.

Once annual repairs hit 15 percent of the cost to replace the boiler, and that happens two years in a row, it is time to budget a replacement. That rule isn’t in the Burnham manual. It’s just a finance rule that keeps me from spending the value of a new boiler on a dying one. (This was true as of 2024, at least. I update the threshold every couple of years.)

The surprise wasn’t that some old Burnham boilers are still running. It was how many facilities skip water treatment and then blame the boiler. Scale and sludge kill heat exchangers faster than age. A heat exchanger leak is a red line. I don’t pay to weld a leaking section; I replace the boiler.

6. How to Clean Ice Maker Machine (and Why It Shows Up in a Boiler Article)

This question seems out of place, but stick with me. In commercial buildings, the ice maker and the boiler often share the same incoming water supply and the same maintenance budget. Hard water affects both.

Quick answer to how to clean ice maker machine: unplug it, remove the ice, clean the bin with warm water and an approved sanitizer, run a descaling solution through the water line, rinse thoroughly, wipe the condenser coils, and replace the water filter. Twice a year is a good starting point, but follow the manufacturer instructions.

Here is the cost connection: I once saw a facility spend $800 a year on ice maker service calls and $1,400 a year on boiler scale-related repairs. We installed a water softener, and both costs dropped. I expected the boiler service cost to stay the same. That surprise is why I now include ice maker cleaning in the same procurement review as boiler maintenance. It is all just total cost of ownership.

Ice maker cleaning is not glamorous, but it is part of the water chemistry story. Scale in the ice maker means scale in the boiler.

7. What is the biggest hidden cost in commercial boiler ownership?

Downtime, not the equipment. If a commercial boiler goes down in January, a small apartment building can lose rent, produce expensive pipe freeze damage, and push you into emergency labor rates. Emergency repairs usually cost double a scheduled service call.

A boiler downtime event in one of my buildings cost $14,000 in hotel rooms for displaced tenants while we waited for a replacement control board. That was one incident. It would have paid for a decade of annual service on that unit.

That’s why I prioritize a supplier that can get parts quickly and answer technical questions without a fight. With Burnham, I have found parts availability and support to be good. But even more important is the startup and water chemistry plan. Get an experienced technician to commission the boiler, test the safety controls, and log the water conditions. (Note to self: I still need to digitize last winter’s water treatment logs before the next audit.)

The question isn’t only what you pay for a boiler. It’s what it costs when the boiler isn’t running. That single sentence has saved my organization more than any line item negotiation ever did.
