"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

"Extremely friendly service. Prompt and professional. It was a little more expensive than I thought it would be to swap out a light/exhaust fan, but the work was excellent and I would hire again in the future."

Customers say: Quality work

"First of all I requested quotes from 3 different plumbers to replace a water heater and install a pressure reducing valve. Todd was very professional, honest and very reasonable priced. He did an excellent job and went above and beyond my expectations. He will be my go to from now on. I HIGHLY recommend him to anybody looking for quality work at a great price."

"On a Monday holiday I turned on my air conditioner and it refused to work. I went to HomeAdvisor and left my name and phone number but called a company that has worked for me before where I got a recorded message. In the meantime Burke plumbing and heating called and left me a message to call them. I called them and they said that they would send someone out that very afternoon. I needed a complete new furnace and compressor. The next day he ordered everything he needed and it arrived to be stored in my garage overnight. The next day he and another workman arrived at 8 AM removed the old system and installed the new. They were finished by 1:30 PM, cleaned up and everything worked like a charm, I would definitely recommend Burke plumbing and heating to anyone needing their service."

Install Boiler FAQs, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.
