    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.

We had a hole in our bathroom sink drain. Called on a Monday, they were there on a Tuesday and put in new pipes. Both Technicians were professional and pleasant. Wouldn’t hesitate to call them again.

Gavin and Mohammed were exceptional in their customer service. Gavin explained my situation to me with excellence and his explanation was clear and well executed. I could tell he was well equipped with knowledge and was confident in his delivery of service which made me feel confident. Gavyn’s personaity made me feel comfortable and secure and was like a ball of sunshine on a cold rainy day.They both were gentlemen, professional and respectful. I’ve been living in my home for 34 years and have never been so impressed with the dynamic service that was provided to me by Gavin and Mohammed ( Haritage Home Service). The initial call process from Heritage was fast and well organized. My experience was nothing short of exceptional to the point where I never thought I’d be so excited to have new shiney, copper pipes! Don’t hesitate to call Heritage and change to them as your new home service company!
