"Mike was great. He took his time to explain what he was doing. I had a sediment filter installed and he replaced the pressure tank. He showed me how to check/replace filter as needed. He came by and diagnosed my problem without charging a service fee. He was very thorough and was not in a rush. His price was fair. He gave his professional opinion and did not try to "sell" me products that were not needed when I inquired about a water softener for my house. Great guys both him and his partner. I highly recommend giving them a call for your next plumbing job!"

"Andrew knocked this install out of the park! He replaced an incredibly inefficient hot water heater with a hybrid hot water heater, ran the condensate line through pipe straps screwed into drop in anchors along our basement wall with the cleanest looking final result that surpassed every expectation I had. He was very communicative well within the budget and will be our go to for any future work we need as long as we live in this area!"

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

"TCC is as good as it gets. After several issues with our GC and the plumber he used, I insisted that we use ours to fix everything that was messed up and/or flat-out wrong in our house. He agreed and I immediately called TCC. First, Joe is the best when it comes to boilers and plumbing issues. He is extremely knowledgeable and very patient when someone like myself, who knows absolutely nothing about boilers, ask a LOT of dumb questions. He fixed an issue that we've been having since we moved into the house last summer - one that our GC's plumber has been to the house on three different occasions to fix and only made worse. I've recommended TCC to clients who needed boiler repairs, plumbing updates and such in their homes and all have been equally as pleased. Are they cheapest around? No. But I've found that, when it comes to contractors, you get what you pay for and if paying a little more means I'll have good service and it'll be done right the first time, then I'll pay it every time. TCC rocks!"

"Bill was willing to install a heat pump system that I purchased, even though his default was Bosch. His son and helper did the install over two days. It was getting late when they finished and the unit worked, although it whistled. I let Bill McGinley know but couldn't get them to come out to resolve the problem for over a week. Bill figured out that air was being sucked in between the top bottom front panels on the ACIQ central unit and did a workaround -- taping over it. The manufacturer ACIQ was no help in acknowledging that there was a problem with their product. I made a mistake paying on the basis of the quote rather then requiring an invoice. When I tried to apply for the NHSaves rebate, they wanted an invoice. Bill was not very responsive in sending me the invoice. He did when I told him NHSaves would be contacting him. But he was very accommodating in doing the work i wanted done instead of doing what he was used to doing."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Devin answered my distress call to a leaking boiler and Jake came out to fix the problem. It is my first boiler system so poor Jake got a lot of questions. He was FANTASTIC!! So professional and kind. Fixed the problem and answered all of my questions. He did not try to over sell me. I felt very comfortable with Jake's work! I am so pleased with the company all around that I signed up for the Care program and look forward to see them for annual maintenance. Thank you from the bottom of my heart Devin and Jake!

Install Boiler FAQs, answered by experts

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

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.
