New Hampshire Boiler Installation | JustCallHeritage.com

Boilers, also known as “forced hot water” systems, are one of the most common types of systems here in New Hampshire. Whether fueled by gas or oil, they can work reliably for you each winter and effectively heat your home even on the coldest days, and not only that but they can even be set up to handle your hot water needs as well.

All this use, however, adds wear and tear to your system, and eventually, you may be faced with the situation of replacement. Replacing your boiler may seem like a daunting task, but at Heritage, we’re here to guide you through the process of making a smart investment.

FAQs

    How to Choose a Boiler For Your Home

    Choosing the right boiler for your home takes some careful consideration. Our heating experts can help you navigate this process. Here are a few considerations to make when deciding on the best boiler to install in your home.

      1. Determine Your Boiler’s Size: Do you have a larger home? Are there many members in your household? You’ll want to install a boiler that will be able to sufficiently warm your home and keep you comfortable. However, if you install a boiler that’s too large, you may experience higher heating costs. Our technicians will carefully determine the perfect boiler size for your home.
      2. Consider Your Efficiency Needs: Do you want to heat your home as efficiently as possible? Efficiency ratings vary between systems, so it can be helpful to compare them side by side to determine which boiler replacement will be most beneficial and cost-effective in the long run.
      3. Connect With a Professional Company: Scheduling a professional boiler replacement is essential to ensure you adhere to local building regulations. When you work with our experienced Heritage team, you can also rest easy knowing that your installation is backed by our workmanship and is completed correctly.
  • How Do Boilers Work?

    A common misconception is that boilers “boil” the water. In most cases, modern boilers don’t heat water to the boiling point, which would be typically found in the steam boilers we may be familiar with. Instead, they heat the water and circulate it through baseboards or radiators that can be controlled through zones, which are adjusted by a thermostat. The more zones you have, the more control you have over how you manage your heat.

  • How Long Do Boilers Last?

    Newer boilers are often classified as “high efficiency.” They use modern materials and construction to achieve top-tier performance, but they typically trade lifespan for efficiency as they experience more wear and tear over their life. You can expect a modern boiler to last ten to 15 years on average. Traditional cast iron boilers are not nearly as efficient but tend to be more affordable and the durability of their construction means they can last upwards of 25 years or more with proper maintenance.

  • Can You Perform Boiler Maintenance Yourself?

    A license must be maintained to work safely with fuels like oil and gas, and it is not recommended to perform maintenance without the proper experience. Bringing in trained experts like our team is the best way to ensure your boiler is working properly and to catch any issues before they become bigger problems. When boilers aren’t maintained properly over the years, this leads to more wear and tear than necessary, making them less efficient and more likely to be replaced sooner than they should.

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!
