  • Water Heater Installation Services in NH

    New Hampshire Water Heater Services

    If you’re on the hunt for a new water heater, there are various options depending on what you’re looking for and how you use hot water in your home. When you work with Heritage, we’ll discuss how you currently use hot water and what you’re looking to get out of the new water heater. By working together to come up with the best option, we can make sure you find the right type of water heater to meet your energy needs and fit your budget, with upfront pricing and financing options.

  • Types of Water Heaters to Consider

    There are two main categories of water heaters: tank and tankless. A tank-based water heater uses a tank to store hot water all the time, whereas a tankless water heater heats hot water on-demand as you need it. For some, a tankless water heater is more than enough for their hot water needs, but for others, especially large families, a tank-based water heater is the way to go.

    Most homeowners choose to replace what they already have or go with a newer, more modern water heater. If you use electric, you’ll tend to stay with electric or go with an electric-hybrid. If you are currently using a gas water heater, you’d stay with a gas water heater. Heritage will consider the fuel source, how old your home is, and where your tank is located to give you all the options for your home’s new water heater.

    One of the final decisions you’ll make when choosing a new water heater is the size. Most homes use a 20 to an 80-gallon water tank, with the most common size being a 40-gallon tank.

Heritage Home Service is Your Water Heater Solution

When choosing a water heater for your home, we’ll work with you from start to finish to understand your needs and help you make the right choice for a new unit. We’ll explain how the unit works, what the installation process looks like, offer transparent pricing, and schedule a time and date that works for your schedule.

Good morning. I recently had service done at my house. I would just like to say a few words about the two electricians who came for that service call. Bryce was the best! They were polite and professional. They diagnosed the issue using a great deal of skill and expertise. They kept me informed every step of the way, and I am more than satisfied with my results! I really have nothing but wonderful things to say about you and your company. I will only use you in the future, and will heartily recommend your company to others. Thank you so much and have a great day!

William was exceptional and knowledgeable. We are in the process of selling our home and purchasing a new home. He walked us through the issues with our current plumbing problem. He also provided us with invaluable information on our new home which has a septic system. I would definitely recommend William to anyone looking for plumbing needs.

called Heritage Home Services expecting a repair and maybe a mild headache. Instead, they showed up on time, knew exactly what they were doing, and somehow made home maintenance feel less painful than assembling IKEA furniture. The technician was professional, friendly, and explained everything in a way that didn’t require an engineering degree. The work was done quickly, cleanly, and without any surprise drama—which, if you’re a homeowner, you know is basically a miracle. My house is happier, my stress level is lower, and I’m pretty sure even my thermostat is smiling. If home service companies had a Hall of Fame, Heritage Home Services would have a plaque near the entrance. Highly recommend them to anyone who enjoys competent service, fair treatment, and not having to watch YouTube tutorials to fix everything themselves.

Ryan O’Connor of Heritage Home Service did a marvelous job installing a smart leak detector on my cold water line. It required some “creative” piping. When he was done, the site was immaculate.

Frequently Asked Questions

  • How do I know when it is time to replace my water heater?

    Most traditional tank water heaters last 8 to 12 years. Signs that replacement is needed include rusty or discolored hot water, rumbling or banging noises from the tank, visible leaks or corrosion around the base, inconsistent water temperatures, and rising energy bills. Heritage can inspect your water heater and recommend whether repair or replacement is the better option.

  • What types of water heaters does Heritage install?

    Heritage installs traditional tank water heaters, tankless water heaters, and hybrid heat pump water heaters in both gas and electric configurations. Our licensed plumbers will evaluate your household hot water demand, available space, and energy preferences to recommend the best option for your home.

  • How long does a water heater installation take?

    A standard water heater replacement typically takes a few hours to complete. If the installation requires changes to your plumbing, gas line, venting, or electrical connections, the job may take longer. Heritage provides a clear timeline during your estimate so you know what to expect.

  • Does Heritage offer financing for water heater installation?

    Yes. Heritage offers financing options to help New Hampshire homeowners manage the cost of a new water heater installation. We provide upfront pricing with no hidden fees so you can make an informed decision before work begins.

  • Should I choose a gas or electric water heater for my New Hampshire home?

    The right choice depends on your home’s existing infrastructure, energy costs, and hot water demand. Gas water heaters typically heat water faster and cost less to operate, while electric models are easier to install and do not require venting. Heritage can help you weigh the pros and cons based on your specific situation.
