"My boiler in Wolfeboro NH failed suddenly. It was old and needed to be replaced anyway but I was hoping to get another season out of it. I called quite a few boiler companies and had difficulty even getting someone to answer the phone. Then I lucked out. I called Ed Grant and he answered his phone. It was November and getting cold. He came out to the house promptly and very professionally installed my new boiler. Not only is this guy honest, straight forward but he is such a hard worker. He worked diligently until the job was up and done. Absolutely no headaches, no bullshit, and not a salesman whatsoever. Ed Grant is the REAL deal if you need a new heating system. I would hire him again in an instant without a worry. A+. Thanks, Ed Brian Whitehouse"

"It went great, Tyler noted that I was handicapped and made sure that my new toilet was ADA approved. I felt it was a nice detail that many would have overlooked. Tyler paid great attention to detail, my bathroom was as clean after the new toilet was installed as it was before and even having to drag the old one through the house my hard wood floors never got a drop of water on them. He was friendly and very polite. I would definitely call him for our plumbing needs again!"

"Work with Tylor. His quality and customer responsiveness is top notch. I had him install 3 mini splits in our home. I originally wanted Mr Cool.. He coached me into upgrading to Mitsubishi for our area due to it’s significant quality increases vs Mr Cool and he was able to purchase and install faster and significantly cheaper than the “Home Depot” “Mr Cool” 3rd party install pricing company Highly recommend Tylor and his work"

"Once again, NE Renovations did themselves proud! We had a problematic boiler system that was giving us fits for years, but were reluctant to pull the trigger for a new one. Richard and the team found the right boiler for our home's layout and our needs. They installed the boiler, took the other one away, and we barely knew they were there! To top it all off, they even took care of the rebate from National Grid and just took that amount straight off the already very reasonable bottom line! What other firm would do that? These guys are great and I will continue to use them for all kinds of work around our home! Professional service, great quality, reasonable prices, and honesty to the point where I am completely comfortable leaving them in my hone alone! Service as it used to be and as it should be!"

Install Boiler FAQs, answered by experts

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.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

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.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
