"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"Plumber came out within hours of calling and offered to install the faucet the same day. Install only took a few hours and he was wrapped up by early afternoon. Fast, efficient and friendly. Just what we needed after waiting over 2 weeks for the other guy to even call us back!"

"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+++"

Customers say: Super punctual

"As part of a second floor renovation, I needed some new baseboard heaters installed in two bedroom, a pipe connecting them relocated/replaced, and some leaky valves replaced on my boiler. Milltown was one of the only plumbing companies that actually returned my calls, and they were able to come out right away, which was great because it was almost October and was starting to get cold. They did an excellent job with all of the work, and I think the price was reasonable for what they did. They were punctual, clean, and professional. No complaints."

"Atlantic Heating & Air Conditioning responded professionally and quickly to my call. A service technician diagnosed the problem and ordered the a new gas valve and two sensors. A second technician, replaced the defective parts and serviced the boiler. Both technicians performed their work in a very professional manner, identified the source of the problem and clearly explained what was needed. I was impressed with their work and would definitely hire them again."

"Have used Scott a few times already. Great service. Needed a shower valve replaced. Used him to install a new under the cabinet kick plate heater. Also needed some old cast iron radiators disconnected and the feeds and returns disconnected when we switched over to a new system. Highly recommend"

"I am totally pleased with the work ethic and quality of Mike's work. This project took several weeks, and he met all his committed dates. The care and quality of his work on my full boiler and indirect tank replacement was excellent, including piping, fitting and pump placement. He then took a lot of time describing how the system works, and I couldn't be happier."

Install Boiler FAQs, answered by experts

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
