"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."

"I had what I felt was an emergency situation. An outside water faucet was not closing and shutting off properly. Spewing water onto my patio area. Nick was here within an hour and not only fixed the problem but installed a new plumbing fixture that is amazing., I can work it without any discomfort with my old lady hands. There is also extra protection from freezing in the cold winter months. I will call him again and refer his company to all my friends."

"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"

Install Boiler questions, answered by experts

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

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.
