Tankless Water Heater Installation in Lexington, MA
Lexington’s 1950s-1980s single-family homes on larger lots are prime candidates for full equipment replacement. Lexington is one of our most active Mass Save Heat Pump conversion markets. For tankless installs specifically, Lexington homeowners typically come to us for one of two reasons: their existing 50-gallon tank is finally giving out and they want endless hot water this time, or they’re planning a kitchen and bath renovation that will demand more hot water than the existing tank can supply.
Tankless Water Heater Brands We Install
Navien: Our most-installed tankless brand. Premium condensing units with built-in recirculation and lifetime heat exchanger warranties on premium models.
Rinnai: Long-time tankless leader with proven cold-climate performance.
Rheem: Strong mid-tier option with excellent serviceability.

What’s Included in Tankless Installation
Pulling and disposing of the existing tank water heater. Resizing the gas line if necessary — most existing 1/2″ gas lines are too small for tankless and need to be upgraded to 3/4″ or 1″. Installing the new tankless unit on the wall with proper structural support. Running new vent to the exterior. Installing condensate drain and isolation valves. Pressure-testing the gas line. Pulling all required permits. Commissioning the unit.

Frequently Asked Questions about Tankless Installation in Lexington
How long does tankless water heater installation take in Lexington?
A standard tankless install (replacing an existing tank, gas line already correctly sized) takes about a full day. If the gas line needs resizing, add 4-8 hours.
Will a tankless really give me unlimited hot water?
Yes — but with a flow-rate limit. A typical residential tankless unit (180,000-199,000 BTU) supplies about 7-9 GPM in our New England climate. That’s enough for 2-3 simultaneous showers in most Lexington homes. For larger demand, we install paired tankless units.
How long does a tankless water heater last?
15-20+ years with annual descaling, vs 8-12 for a typical tank.
Can I qualify for Mass Save rebates on tankless in Lexington?
Yes — high-efficiency tankless water heaters qualify for Mass Save rebates. We handle the rebate paperwork.
