FAQs

  • Tankless Water Heater Services in Massachusetts

    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.

Called on a Thursday with an active leak…actually a drip…found by luck on the cellar floor. Vinny showed up less than 24 hours later, and after diagnosing the issue found the problem. It wasn’t what I thought, but his perseverance paid big time dividends. On a Friday early evening Vinny made a trip to a Home Depot 30 minutes away, and when he returned the problem was solved in 30 minutes. Heritage upgraded our electrical system from 100 amp to 200 amp, and installed a whole house generator for us during the winter, so we were very familiar with the company. I can’t say enough good things about their workmanship, their customer service, and their professional employees. I would be pleased to have Vinny come back should the need arise. He was great!!
