Hot Water Heater Replacement Massachusetts
What Massachusetts Homes Need in a Water Heater
Searching for water heater replacement near you in Massachusetts usually means one of two things: the tank is leaking or running cold, or it’s old enough that you’d rather not find out when it quits. Either way, you want a straight answer on repair versus replace, and on what should go in its place.
Dempsey Energy is a family-owned company based in North Attleborough. We handle residential water heater replacement across Massachusetts, from Foxboro and Mansfield to Quincy, Dedham, and Canton, and we start by looking at your home: the fuel you use, the basement it sits in, and what it’s connected to.
What You Can Count On
Licensed Plumbers Every Job
A licensed plumber handles your water heater replacement from start to finish, so the work meets Massachusetts requirements and local codes.
Pricing Before Work Starts
You get the price in front of you before work begins, so venting or permit surprises don't show up later on your bill.
Mass Save Partner
We help you check which Mass Save rebates apply to your new water heater before you buy anything, so you don't miss out on savings.
Emergency Help Around the Clock
When your tank leaks or the hot water quits, emergency service is available 24/7 across our Massachusetts service area.
Gas Water Heater Replacement Massachusetts
Venting Decides Your Gas Replacement Price
Gas water heater replacement in Massachusetts is where quotes drift furthest apart, and venting is usually the reason. In an older New England home, a basement unit may vent into a chimney, while a power-vent model runs out through a wall. Changing from one to the other changes the labor and the parts.
Many Massachusetts homeowners see installed costs of roughly $1,800 to $3,500 for a standard gas tank replacement, depending on venting, fuel, and size. We settle your price before the work starts, so you know where in that range you land. And if your house runs on a boiler, we’ll price an indirect tank too, which the boiler feeds and which can last 15 to 20 years.

Electric Water Heater Replacement Massachusetts
Heat Pump Savings Depend on What You Replace
Electric water heater replacement in Massachusetts comes down to one question: stay with a standard electric tank, or move to a heat pump model? Heat pump water heaters use 60 to 70 percent less electricity than a standard electric tank, so the savings are real if that’s what you have now. Compared with gas, the savings shrink to roughly $175 to $325 a year, with a payback of 6 to 11 years.
We’ll tell you which side of that line your home sits on. If the $750 Mass Save rebate applies to the unit you choose, we’ll help you line up the steps in the right order so you get the rebate.

Frequently Asked Questions
How much does water heater replacement cost in Massachusetts for a standard gas tank?
Many Massachusetts homeowners see installed costs of roughly $1,800 to $3,500 for a standard gas tank replacement, depending on venting, fuel, and size. Electric water heater replacement typically runs $1,500 to $2,800, a heat pump water heater $3,500 to $6,500, and a condensing tankless gas unit $4,000 to $7,500. Those are general ranges, not our quotes. Your number depends on what’s already in your basement and what has to change to fit the new unit, which is why we price after we see it. We also run a limited-time $300 Off Water Heater Replacement offer. Mention it when you book, call for details, and note that it can’t be combined with other offers.
Is there a Mass Save rebate if I install a new hot water heater?
Yes, for heat pump water heaters. Mass Save offers a $750 rebate on qualifying models, generally those with a UEF of 2.0 or higher. Income-qualified households may have additional options, so ask when you call. The federal 25C tax credit expired on December 31, 2025, so older articles quoting a 30 percent credit are out of date. Mass Save budgets changed in 2025, and some programs require eligibility or model approval before you purchase. Check before you buy a new hot water heater, not after. As a Mass Save partner, we can help you confirm what applies to your home in Massachusetts.
Should I repair or replace my water heater if it's around 12 years old?
When you’re deciding whether to replace a water heater in Massachusetts or repair it, start with where the problem is. If it’s leaking from the tank itself, replace it, because a leaking tank can’t be repaired. Rust-colored water or a tank full of sediment points the same way. Most gas and electric tanks last about 8 to 12 years, so a 12-year-old unit that’s still heating is living on borrowed time, and tanks that age tend to fail without warning. If it’s younger and the problem is a thermostat, element, or valve, repair often makes more sense. We’ll tell you which it is, and we’ll say so if your tank has years left.
Do I need a licensed plumber and permit for water heater replacement in Massachusetts?
Yes. Massachusetts requires a licensed plumber and a permit for water heater replacement, and gas and venting work is not a place to cut corners. Whether you’re in Quincy, Foxboro, Dedham, or anywhere else we serve, the permit and local inspection go through your town. Skipping them can create problems with your warranty and leave a venting mistake unchecked. We use licensed plumbers on every job, and we walk you through the permit and inspection so you aren’t left chasing paperwork after the install.
How long does water heater replacement take in a typical Massachusetts home?
A straightforward swap is often finished in a single visit, typically 2 to 4 hours. Tankless conversions and venting changes take longer. We offer emergency service 24/7, so if you need emergency water heater replacement in Massachusetts on a cold night in Norwood or anywhere in Plymouth County, call and we’ll tell you honestly how soon we can be there. We won’t promise same-day on a job that needs a new vent or gas line. Older New England homes with tight basement spaces can add time too, so a quick look at your setup gives the best answer.
Gas, electric, tankless, or heat pump: which water heater makes sense for my home?
Choosing a new hot water heater in Massachusetts depends on your fuel and your house. Gas is cheaper to run than electric resistance, so gas homes usually stay gas. Electric homes are the best candidates for a heat pump model, and the rebate helps. Tankless can last about 20 years, but it needs the right gas line and venting and costs more up front, so it isn’t right for every home. If you heat with a boiler, an indirect tank is worth a look. For residential water heater replacement across Bristol, Norfolk, and Plymouth Counties, we compare options for your home and explain why we recommend one. Then our Dempsey Comfort Club keeps it maintained, with priority scheduling.
