Tankless Water Heater Services

Hot water is an important part of your daily routine. If you’re tired of lukewarm showers and high water heating costs, it may be worth switching to a tankless water heater. Also known as an on-demand water heater, this appliance heats water when you call for it instead of storing it in a tank.

When you turn on a faucet, cold water enters the unit, and hot water comes out within seconds. More Massachusetts homeowners are going tankless to enjoy endless hot water and lower utility bills. If these benefits appeal to you, LePrevost Plumbing, Heating & Cooling would be happy to discuss the possibility of a tankless upgrade.

Our Tankless Water Heater Services

Tankless systems are not one-size-fits-all. The right approach depends on your household size, hot water usage, fuel source, and incoming water temperature. Our services cover every stage of ownership, from planning a replacement to long-term care, so your water heater continues to perform year after year.

System Sizing & Recommendations

Honest recommendations come first when going tankless. This either means confirming that a tankless system is a good fit or suggesting other energy-efficient water heaters as alternatives. Our licensed plumbers always recommend systems that fit your home, your budget, and your hot water demands.

Sizing comes next. Flow rates, simultaneous usage, and incoming groundwater temperature all factor into the ideal tankless water heater size. We calculate everything carefully and explain your options clearly, which might include installing a single whole-house system or multiple point-of-use units. Our goal is to help you enjoy steady hot water at every fixture without overspending.

Installation & Replacement

Tankless water heater installation requires technical precision. Our team handles every detail related to fuel lines, electrical capacity, venting, and water quality to ensure your investment performs as expected from day one.

We replace aging tank units in existing homes and install new on-demand water heaters in new builds. We plan replacements to limit downtime, so you’re not left without hot water for days. Each installation is performed to code and tested under real-world conditions.

Condensing & Non-Condensing Gas Tankless Systems

Gas tankless water heaters fall into two categories: condensing and non-condensing. Condensing models capture and reuse heat from exhaust gases, making them more energy-efficient. Non-condensing systems have a simpler design and may be practical for smaller households or specific replacement scenarios.

We’ll explain how each type performs in real-world conditions, including venting requirements, fuel usage, and long-term operating costs. This knowledge will help you decide what’s best for your needs.

Preventative Maintenance

While not as maintenance-heavy as traditional tanks, routine upkeep helps tankless water heaters run more efficiently, break down less often, and last longer. Annual flushing is recommended to remove mineral buildup, thereby protecting internal components and improving heat transfer.

Tankless Water Heater FAQs


Most installations are completed in one day. Homes that need gas line upgrades, electrical work, or venting adjustments may take longer. We’ll discuss the timeline before work begins.

Gas tankless water heaters still need electricity for ignition and controls, so they will not produce hot water during an outage. Some homeowners install a battery backup or generator to keep their on-demand water heater running uninterrupted.

Yes, as long as the system is sized properly, it should accommodate multiple hot water activities. Homes with high flow-rate demands may benefit from multiple point-of-use units rather than a single whole-home system.

The entire team at LePrevost is first class! From the owner to all of the employees I’ve worked with, they’ve been courteous, responsive, professional and a good value.

Liv D.

Furnace started acting up during the coldest day of the year and they were able to send someone to fix it without having to wait days or weeks. Thank you!

Phil T.

I received outstanding service from LePrevost. Very quick response regarding an emergency. Problems solved! This is the best service company I have used in many years.

Roger L.

Very responsive and repaired all I needed in 30 mins. After calling multiple plumbers around the area who never called me back, I found LePrevost through a google search. I was very happy with the technician who fixed a leak in the shower and replaced a toilet pump.

Manuela J.

Over the last several years I have had issues with my furnace. The last 2 times they were emergency calls. Both times the same technician showed up and found the issue right away and took care of the problem. The technician was very knowledgeable and professional.
