    Tankless Water Heater Installation

    Heritage has a team of experts who specialize in tankless water heater installations, and better yet, we make it easy in helping you decide what’s right for your home, whether you’re replacing an existing tankless system or looking to make the switch from a traditional water heater. In most instances, we can even install a system and have you up and running the very same day.

    Tankless Water Heater Repair

    As we mentioned earlier, many situations where a tankless water heater needs repair are because they have not been properly maintained. For example, by not flushing your water heater yearly, the mineral build-up eventually clogs the heat exchanger causing it to stop heating water. Issues with the electronic controls can also be a reason for repairs. Heritage’s trained team will diagnose and fix water heater issues for you and recommend additional steps if it’s time for a replacement. We’ll give you all the options to make the best decision on what to do next.

    Tankless Water Heater Maintenance

    Tankless water heater maintenance is essential to keep your water heater running properly all year long. We recommend annual maintenance to flush the unit, removing mineral build-up and sediment that could damage the water heater and shorten its lifespan. Annual maintenance also helps catch potential issues before they become larger problems and is usually required by the manufacturer to maintain your warranty.

  • What Makes Tankless Water Heaters Unique?

    Understanding the Difference Between Tankless Water Heaters & Traditional Water Heaters

    A traditional water heater stores hot water in a large tank. When you turn on the faucet, hot water is sent through the pipes, and the tank then refills and reheats. Traditional tank water heaters can run on gas, oil, or electricity. On the other hand, tankless water heaters, also known as on-demand water heaters, do not rely on preheated water. They are installed close to faucets and heat the water as it passes through the pipes. Tankless water heaters can run on gas or oil.

    What Are the Benefits of a Tankless Water Heater?

    Traditional water heaters take up a lot of room and can take a long time to fill with hot water. This means you may have to wait for several seconds or minutes to receive hot water in your faucets, showerheads, and water-using appliances. Furthermore, traditional tank systems are not as efficient as tankless models. Our team can discuss your options and install a tankless water heater for your home.

    With a tankless water heater, you can enjoy:

    • Improved energy efficiency
    • Lower utility bills
    • Clean and fresh water
    • Instant hot water to your faucets
    • Longer-lasting system

    Traditional tank water heaters can become rusted or corroded over time. With a tankless unit in place, you can rest assured knowing the system will provide clean and fresh water to your faucets. Furthermore, tankless systems last nearly twice as long as traditional water heaters – up to 20 years or more. Traditional systems typically last only 10-15 years. Tankless water heaters also take up much less space and can be installed virtually anywhere in your home.

  • Tankless Water Heaters Are Energy Efficient

    According to the U.S. Department of Energy, tankless water heaters can be up to 34% more energy efficient than traditional water heaters for homes that use less than 41 gallons of hot water per day. For larger households that use more than 86 gallons of hot water each day, tankless systems can be up to 14% more energy efficient than traditional water heaters.

    While tankless systems are more energy efficient and last longer, they are not able to provide hot water to multiple appliances at once. Thus, if you use your dishwasher and take a shower at the same time, it may overload the system. Installing multiple tankless units in your home can fix this problem.

We worked with James and if possible we will be requesting he come back for future visits! The service was amazing, the price was reasonable, and scheduling was super easy. They were able to show up within 24hrs of requesting their help, and James was even early to the appointment! I can’t say enough good things about this company, they’ll definitely be our go to moving forward.

James was fantastic with all the work he did on our house. We had him and Carter (who was also amazing) install some lights in our 1870s farmhouse. They started with the work downstairs which was adding in new lights in the kitchen, living room, and our bedroom downstairs. On top of the light additions they also fixed some other electrical issues we found during inspection and they installed new smoke and CO detectors. The work was amazing. We then had James and Carter come back to install lights in the 4 bedrooms upstairs. 2 of those bedrooms had never had lights before. They did a fantastic job. Highly recommend them to anyone. They respond very fast and the turnaround time is amazing.

Alex is a true professional! He diagnosed my problem with my Bosch Furnace and fixed. Additionally, he found dirty flame rod and coil that Pine State Services supposedly cleaned in the annual service in June, however, since it had not run since then I have serious questions about that “service”. Highly recommend Heritage Home Service and Alex!

Jimmy was on time, explained everything clearly, advised me about best practices with the system, what to look out for, explained how my system was looking, and got it done well. Refreshingly awesome to have someone enter your home who only wants to do good work, treat people well, and be treated the same. I hope Gelinas is doing well by this guy, the combi-boiler guru.

Our kitchen sink began to leak all under the cabinet last night. We got it cleaned up enough to be okay through the night, but as soon as morning came around, we knew we would need a plumber ASAP. So, we looked up plumbers in our area on Angi. Heritage was the first listing that came up. They answered the phone on the first ring, and before we knew it, Noah was at our house. We were amazed at how quickly we were able to get an appointment. He was knowledgeable, very polite and friendly, and he worked quickly and efficiently. He was everything we could hope for. Our new kitchen faucet is beautiful, nothing leaks in the cabinet underneath, and he even fixed our bathroom toilet lickety-split, too. Even better, we were able to schedule Heritage to come tomorrow to look at an outdoor outlet that we’re having trouble with. We are so pleased with everything. We would highly recommend this company to anyone in need of a plumber or the other services Heritage provides. Thank you, Noah, and thank you, Heritage!

Technician George Fiske instructed us on all the things we needed to know about maintenance and functioning of the new to us gas furnace (which is located in the attic). We just moved into this condo and needed this guidance….he also did the same with our central AC, hot water heater and even our Nest thermostat! Very very helpful and George was terrific. Will call Heritage for the plumbing issues we need to address also!
