Heritage Home Service Tankless Water Heater Services
With its unique design that improves efficiency, a tankless water heater can save on your home’s overall fuel costs. A traditional tank-style water heater continually heats water stored in a large reservoir (tank). As you use this supply, the tank has to constantly reheat the same reserve regardless of how much water you use. It does this slowly, and you may often find yourself in a situation where a shower runs cold after too much use at one time. With a tankless water heater, the water is heated only as you use it, and it does so nearly instantaneously. This essentially gives you an endless supply of hot water, in a more efficient package.
If you’re looking to make the switch, or already own a tankless system, Heritage offers tankless water heater repairs, new installation, and maintenance for New Hampshire residents. Read on to find out more about our tankless services.
Tankless Water Heater Maintenance
Owning a tankless water heater means routine annual maintenance is required to keep it running properly throughout the year. Many New Hampshire towns tend to have a lot of minerals in their water, which can cause build-up, hurting efficiency if not flushed out annually. When we install a tankless water heater for homeowners, we install a service port on all units to ensure it’s easier to maintain in the future. Unfortunately, many companies opt not to install a service port, which requires the unit to be taken apart and one installed before it can be serviced in the future.Tankless Water Heater Repair
With proper maintenance, most repair issues can be avoided or caught before they become too severe, however, due to the high-efficiency nature of a tankless system, even small issues if not addressed soon enough can lead to major problems down the line. If you’re looking for a repair on your tankless water heater, we have certified experts to help you get back to enjoying your hot water as soon as possible.Tankless Water Heater Installation
Whether you’re replacing an existing tankless water heater or looking to make the switch, Heritage takes away the guessing when it comes to choosing the right system for your needs. In most instances, we can even have your new system installed and up and running the same day. We’ll also pull any necessary permits required by your town so you can be sure you received a job done right.

Angel was super helpful and patient with our (very overdue) boiler maintenance. He explained the process before starting, provided estimates for possible work needed without feeling pushy, and was able to repair nozzle damage the same day. Very happy with the service and will keep Heritage in mind for the future.

Frequently Asked Questions
-
What are the benefits of a tankless water heater over a traditional tank?
Tankless water heaters heat water on demand rather than storing hot water in a tank, which means you never run out during back-to-back showers or heavy usage. They are more energy efficient because they only heat water when you need it, they take up significantly less space, and they typically last longer than traditional tank water heaters.
-
How much does a tankless water heater installation cost in New Hampshire?
The cost of a tankless water heater installation depends on the unit size, fuel type (gas or electric), and the complexity of the installation. Heritage provides upfront pricing and free estimates so you know exactly what to expect before work begins. We also offer financing options to help manage the investment.
-
Can my New Hampshire home switch from a tank to a tankless water heater?
In most cases, yes. Heritage can retrofit your home to accommodate a tankless water heater. The installation may require upgrades to your gas line, venting, or electrical supply depending on your current setup. Our licensed plumbers will assess your home and explain exactly what is needed before any work begins.
-
How long does a tankless water heater last?
Tankless water heaters typically last 20 years or more with proper maintenance, which is significantly longer than the 8 to 12 year lifespan of a traditional tank water heater. Regular descaling and filter cleaning help maximize the unit’s efficiency and lifespan.
-
Does Heritage service and repair tankless water heaters?
Yes. Heritage provides complete tankless water heater services including installation, maintenance, descaling, and repair. Whether your tankless unit is not producing hot water, displaying an error code, or due for its annual maintenance, our licensed plumbers can help.
