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.

    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.

Dennis at Heritage Home Service diagnosed my problem with my boiler within 20 minutes! It took an hour or so for him to address three issues with the system and it’s purring like a kitten now. He gave me an estimate for a new water tank, which was already slated for replacement this winter; very reasonable. So informed and helpful!

    A standard boiler installation typically takes 1 to 2 days, depending on whether it is a straightforward replacement or requires modifications to existing piping, venting, or fuel lines. Heritage handles every aspect of the installation so your home is back to full heat as quickly as possible.

  • How do I know what size boiler I need for my New Hampshire home?

    The right boiler size depends on your home’s square footage, insulation levels, number of heating zones, and climate demands. Heritage performs a detailed heat load calculation to recommend a boiler that is properly sized, ensuring efficient operation without wasting energy.
