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.

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!
