Tankless Water Heater Installation in Norwell, MA

Running out of hot water partway through back-to-back showers is a familiar frustration in Norwell homes with an aging tank water heater. A traditional tank holds a fixed supply of hot water, and once it’s gone, everyone waits for it to reheat. A tankless system solves that problem by heating water on demand as it flows through the unit, which means no more racing to shower before the tank runs dry. For homeowners in Norwell replacing an aging tank, it’s also a chance to reclaim closet or basement space the old unit used to take up.

 Trustindex verifies that the original source of the review is Google. Colin was the licenses oil burner technician who recently assisted us.  He did a great job on our forced hot air system tune up.  The service was spotless and thorough, we were highly impressed. We also worked with Full Swing following a pinhole leak on a copper pipe and that service was also fantastic.  Responsive company with skilled plumbers and technicians.

At 930 on the Saturday night of a holiday weekend our waistline snapped from the basement wall, leaving a couple inches of waste resting on the basement floor. My first call was to the plumber with the best Google reviews, and within 5 min I had an appointment with Full Swing at 8am the next morning.

Sunday morning Jordan from Full Swing came out and right away gave me the peace of mind and confidence that this would be taken care of. He put together a plan to temporarily fix the issue, then set me up with the team at AirCare Environmental Services to clean up the mess (they showed up within a couple hours). Trust me, it needed to be cleaned up before work could start.

Jordan did all this BEFORE getting me an estimate. His priority was getting me back to baseline, not getting the job. He didn't know it, but right there he had my business.

Price and timing? When I hear replacing major pipes in the home, having to go through the foundation, and digging up a section of yard, I anticipated 5 figures and taking days. My gauge must be off, because the estimate was well below what I expected and Jordan and Colby finished in a few hours.

Next time I need help with plumbing, my first call will be to Full Swing!

 Trustindex verifies that the original source of the review is Google. Needed tune up on a 2 zone natural gas heating system (Bryant & a Trane furnace) and couldn't get anyone to show up until we contacted Full Swing. They booked appointment the next day. We received arrival notification. The technician (Nolan) was beyond excellent. He explained all the tests he was running & systems he was checking. Friendly, knowledgeable, & professional.

Why Norwell Homeowners Are Switching to Tankless

A tankless water heater offers a few clear advantages over a traditional tank, especially for busy households. The U.S. Department of Energy notes that tankless units can be more energy efficient than tank storage water heaters for homes that use less than roughly 41 gallons of hot water a day.

Hot water on demand: Water heats as it flows through the unit, so you’re never waiting for a tank to refill and reheat.
Compact footprint: Tankless units mount on a wall and take up a fraction of the space a traditional tank requires, freeing up room in a basement or utility closet.
Longer service life: Tankless systems typically last longer than tank units, since there’s no tank to corrode or leak over time.
Lower standby energy loss: Because the unit only heats water when it’s needed, it avoids the constant reheating cycle that tank units go through to maintain a full tank of hot water.

These benefits add up over the life of the unit, even though a tankless system typically costs more upfront than a comparable tank replacement.

Installation Options and Related Services

Choosing the right tankless system depends on your home’s hot water usage, fuel source, and existing plumbing setup.

Gas and Electric Options

We install both gas and electric tankless water heaters, and the right choice depends on your home’s existing utility setup and hot water demand. Gas units generally handle higher flow rates for larger households, while electric units can be a simpler installation in homes without an existing gas line to the water heater location.

Related Services

A tank-to-tankless conversion sometimes requires gas line services to support the new unit’s fuel requirements. If hard water is a concern in your area of Norwell, pairing a new tankless system with a water softener helps prevent mineral scale from building up inside the unit and shortening its lifespan.

Why Choose Full Swing for Tankless Water Heater Installation?

We’ve been installing water heaters for Norwell homeowners since 2015, and a few things set our installation service apart.

Frequently Asked Questions

How much should it cost to get a tankless water heater installed?

Installation costs depend on the unit’s capacity, whether it’s gas or electric, and whether any venting or gas line work is needed for the switch from a tank system. A plumber can give you an accurate quote after evaluating your home’s existing setup and hot water demand.

What is the downside of tankless water heaters?

The main downside is a higher upfront installation cost compared to a like-for-like tank replacement, and gas units may require venting or gas line upgrades depending on the home’s existing setup. Over the life of the unit, though, many homeowners recover some of that cost through lower standby energy losses and a longer equipment lifespan.

Do tankless water heaters need special maintenance?

Yes, tankless units benefit from periodic flushing to clear mineral buildup, especially in areas with harder water, since scale buildup can reduce efficiency and shorten the unit’s lifespan. A yearly flush and inspection is generally enough to keep a tankless system running at full efficiency.
