"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"The Fellowship Team recently installed a new boiler system for me and the experience was flawless from start to finish. Replacing a primary heating system is a major investment, but this team made the entire process stress-free. The installation was incredibly clean. The technicians routed the new piping with surgical precision, ensuring everything was tidy, secure, and easy to access for future maintenance. Since the install, my home reaches the target temperature much faster than before, and the unit runs so quietly I barely notice it?s on. I?m already seeing the benefits in my lower monthly energy bills. The crew arrived on schedule, was sure to not damage anything, and clearly explained how to use the new digital thermostat before they left. They treated my home with genuine respect. It is rare to see this level of dedication to quality. If you need a reliable, high-performing heating system installed by pros who actually care about the details, look no further. Highly recommended"

"The whole process from the beginning to end was well organized, clean, efficient and overall a pleasure. The contractor communicated Via email with step by step instructions on how to get 0% financing through National Grid, arranged for RISE to come in after the boiler was set, and applied for a gas rebate before I asked about it! Highly recommended and will do business with Driver again."

"Removed and disposed of old cast iron baseboard in kitchen (to make way for sliding patio doors) then supplied and installed copper piping & fittings to re-connect remaining baseboard. Chris and team always do a good clean job and I like the ease of doing business."

"we had many problems with a burnham high efficiency system installed in 2009. We called NEBWs and Steve came down. He is very informative, courteous and attentive to our concerns. Within a week we had a new SlantFinn boiler installed and the installation was immaculate. Very neat and organized presentation. Experts in their fields, true professionals and reasonably priced. High recommend"

"Paul provided estimates for the 2 types of tanks I was interested in. Once tank type was decided on, a date for work was set. Paul and his team showed up on time and the job was completed in a timely manner. The quality of work and product are excellent. Work area was left completely clean. I am very pleased with the job done and would highly recommend New England Tank Service. Thanks again Paul!"

Install Boiler questions, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
