Water Heater & Boiler Installation & Replacement

Heat and hot water done right — water heater installation, replacement & repair and boiler installation across Greater Boston: tankless, tank, heat-pump and indirect water heaters, plus condensing and standard boilers. Ask about Mass Save rebates.

Quick answers

Which water heater or boiler is right for a Massachusetts home?

A standard tank water heater is the lowest-cost replacement and lasts about 8–12 years; a tankless unit costs more to install but lasts 20+ years and uses less energy; a heat pump water heater is the only option Mass Save still rebates ($750). For heat, a condensing boiler reaches up to ~95% efficiency versus about 80–85% for a standard boiler, but since 2025 Mass Save no longer rebates gas or oil boilers.

Tank water heater8–12 yearsStandby heat loss around the clock$1,800–$3,500No
Tankless water heater20+ years with annual descalingRoughly 8–34% less water-heating energy (U.S. DOE)$3,500–$6,500No (gas)
Heat pump water heaterAbout 10–15 years2–3× as efficient as a standard electric tank (U.S. DOE)Quoted per homeYes — $750 rebate + 0% HEAT Loan
Condensing boilerAbout 15–20 yearsUp to ~95% AFUEQuoted per homeNo (since 2025)
Standard (non-condensing) boilerAbout 20–25 yearsAbout 80–85% AFUEQuoted per homeNo

Costs are the typical ranges we quote; your exact price depends on venting, gas or electrical upgrades and permits, and we confirm it upfront. Rebate status per our Mass Save guide (2026 program year). Every installation is permitted and inspected — see MA water heater permit rules.

What it costs

What affects the cost of a new water heater or boiler?

There's no single price — the cost of water heater replacement or a new boiler depends on a handful of things, and we give you an upfront, honest quote after we see the job. The biggest factors:

  • The type of unit — a standard tank water heater costs less to install than a tankless, heat-pump or high-efficiency condensing boiler.
  • Size & capacity — the right gallon or BTU rating for your home and hot-water demand.
  • What has to change — new venting, a gas line upgrade, or switching fuel type adds labor and materials.
  • Permits & old-unit removal — pulling the proper permit, inspection, and hauling away the old heater.
  • Mass Save rebates — heat pump water heaters and heat pumps may qualify for rebates and 0% HEAT Loans (gas and oil boilers no longer do) that lower your net cost.
Common questions

Frequently asked

How much does a new water heater or boiler cost?

It depends on the type of unit, the size your home needs, and whether venting, gas lines or fuel type have to change — plus permits and removal of the old unit. A standard tank water heater is the lowest-cost option; tankless, heat-pump and condensing boilers cost more up front but run more efficiently; heat pump water heaters also qualify for a Mass Save rebate (gas and oil boilers no longer do). We give you an upfront, honest quote after an on-site look. Call +1 (774) 486-0909.

No heat — can you come today?

Yes. No heat and no hot water are treated as emergencies — we answer 24/7 and offer same-day visits across Greater Boston. Call +1 (774) 486-0909.

Tankless vs. tank water heater — which is right?

Tankless gives endless hot water and lower bills with a higher up-front cost; a tank costs less to install. We'll size both options for your home and usage and give you an honest recommendation.

Can you help with Mass Save rebates?

Yes, where they genuinely apply. Heat pump water heaters ($750) and air-source heat pumps still qualify for Mass Save rebates and the 0% HEAT Loan; since 2025 gas and oil boilers, even condensing models, no longer get standard rebates. We check what applies when we quote the job.
