Navien Tankless Water Heaters in Mansfield
Endless Hot Water Built for New England Homes
Few things disrupt a routine quite like stepping into a cold shower on a frosty Massachusetts morning. Traditional water tanks have served local properties for generations, but keeping 40 to 50 gallons of water continuously heated around the clock consumes significant energy. As energy costs change and equipment ages, many homeowners in our area are looking for smarter, more efficient alternatives.
Navien tankless water heaters offer a modern approach to household hot water. Designed to heat water on demand rather than storing it, these systems provide a continuous stream of hot water while taking up a fraction of the room required by traditional tanks. At Quarry Hills Plumbing & HVAC, we have been serving residential and commercial properties across Mansfield and neighboring communities since 2008. Our goal is to help you select and install heating and plumbing equipment that keeps your building operating smoothly while managing energy usage effectively.

Why Navien Tankless Water Heaters Perform So Well in Mansfield
Navien has built a reputation across North America for engineering high-efficiency condensing tankless systems. Unlike standard water heaters that constantly burn fuel to keep standing water warm, a tankless unit fires its burners only when a hot water faucet opens somewhere in your building.
Dual Stainless Steel Heat Exchangers
Many tankless water heaters on the market use copper heat exchangers, which can degrade over time when exposed to hard water or shifting mineral levels. Navien equips models like the NPE-2 and NPE-A2 series with dual stainless steel heat exchangers. Stainless steel resists mineral scale accumulation, tolerates intense heat cycles, and extends the overall operational life of the unit.
High-Efficiency Condensing Technology
Standard water heaters vent a significant amount of heat directly out of the chimney or flue. Navien condensing units capture that extra thermal energy from exhaust gases and use it to preheat incoming groundwater. This process allows these units to achieve high Uniform Energy Factor (UEF) ratings, turning more of your fuel directly into usable hot water and cutting down on monthly gas bills.
Built-In Recirculation Options
Our groundwater in eastern Massachusetts gets cold during the winter months. In larger homes, it can take a minute or two for hot water to travel from the basement up to second-floor bathrooms. Navien NPE-A2 models feature a built-in ComfortFlow® recirculation pump and a small internal buffer tank. This design keeps hot water moving through your supply lines, eliminating long wait times at the tap and preventing sudden temperature drops when multiple fixtures run at once.

Thank you Quarry Hills!
“Quarry Hills Plumbing put my system years ago but I had not needed service in a long time. My AC started shutting down unexpectedly on a Friday before the hottest weekend of the year. I called in the morning and Quarry Hills was able to send Tim out same day and he got my AC up and running shortly after, and gave me some tips to prevent pollen and debris from causing future issues. I am so grateful for such prompt and effective service and will be buying a maintenance plan going forward.”- Joan W. -

I would recommend Bill and his company to all my friends.
“Bill the owner responded within a half an hour in a Sunday to help my Mom with her AC. He diagnosed the issue quickly and performed a short term repair to allow us to use the AC until he was able to find a control board because our system is older. Once he found the board he sent out Jon the technician and he was great with my Mother who is older and was very thorough. I was at work and he called me when he was done to tell me everything was working properly. I would recommend Bill and his company to all my friends.”- Michael J. -

Practical Benefits of Switching to a Navien System
Upgrading from a standing tank to a wall-mounted unit changes how your entire household manages daily routines:
- Continuous hot water flow. Run the dishwasher, start a load of laundry, and take back-to-back showers without running out of hot water.
- Reclaimed floor area. Traditional tank heaters take up substantial floor space in basements or utility closets. Navien units mount neatly on the wall, freeing up valuable storage area.
- Reduced energy consumption. Heating water only when needed eliminates standby energy loss, lowering your overall monthly utility expenditure.
- Preventing emergency basement flood cleanups. In our experience servicing local homes, most conventional tank failures don't start with obvious leaks, they fail from internal bottom-corrosion that ruptures without warning while homeowners are away or asleep.
How to Keep Your Unit Operating Efficiently
While Navien systems are engineered for durability, periodic care keeps them running at peak efficiency for years to come.
- Countering local scale buildup. The mineral content in eastern Massachusetts groundwater forms a thin lime scale layer inside heat exchangers as water heats up. Skipping annual flushing forces the burners to run hotter and longer just to penetrate that scale barrier, leading to error codes and premature component strain.
- Rinsing the cold water filter. Navien units include an accessible inlet filter designed to trap sediment and debris before water enters the heating chamber. Checking and cleaning this screen periodically keeps water flowing freely through the unit.
To make routine upkeep simple, we offer our Comfort Club maintenance program. Members receive proactive annual inspections, scheduled maintenance for heating, cooling, and plumbing systems, and exclusive service perks throughout the year.
Why Locals Choose to Work with Us
Converting a home from a conventional standing tank to a high-efficiency Navien unit is more than swapping out appliances. It requires proper sizing, precise gas pressure verification, and clean condensate line routing to meet local municipal plumbing codes. Since 2008, our team has handled these retrofits across Mansfield and surrounding neighborhoods, learning the unique piping and layout quirks common in older New England homes.
As active members of the Tri-town Chamber of Commerce, we take personal pride in every jobsite we walk onto. When our technicians work in your basement or utility room, we use drop cloths, clean up all copper shavings and old fittings, and leave your workspace cleaner than we found it.
Every new equipment installation we complete comes backed by a one-year parts and labor warranty, giving you tangible protection beyond standard manufacturer coverage. We also provide direct savings for military families, veterans, and local seniors across our community. Whether you need an emergency repair on a failing water heater or a complete conversion to continuous tankless hot water, our licensed team delivers practical, long-lasting results.
FAQs
Will my existing gas line work with a Navien water heater?
Navien units feature technology that allows them to operate on standard 1/2-inch gas lines in many homes, provided the gas pressure and total fuel load of all appliances on the line stay within safe parameters. We test your gas line pressure during our initial evaluation to confirm compatibility.
How long does a Navien tankless water heater last?
With basic annual maintenance and routine descaling, a Navien condensing tankless unit can operate for 20 years or more. This is roughly double the expected operational lifespan of a standard storage tank.
What happens to a tankless water heater during a power outage?
Navien units require electricity to power the electronic control board, internal sensors, and ignition system. If power outages are a concern in your neighborhood, we can discuss battery backup systems or generator connections to keep your hot water available during storms.
