How much you get
Mass Save pays $750 for a standard ENERGY STAR certified heat pump water heater, rising to as much as $2,250 for households at or below 80% of the area median income. Lawrence has one of the lowest median household incomes in Massachusetts, so a large share of homeowners here should expect to qualify for the higher tier rather than assuming the base $750, and it's worth confirming before you budget.
Gas-to-electric in Lawrence's mill housing
Lawrence's utility setup is split: National Grid delivers electricity while Eversource delivers gas here, having taken over the former Columbia Gas of Massachusetts territory in 2020. A heat pump water heater swap touches the electric side of that split, so it's administered as a National Grid-territory rebate even though the dollar amount is set statewide by Mass Save. For a lot of Lawrence homeowners, this is also a gas-to-electric conversion, since the city's housing, built quickly and densely for mill workers around the turn of the 20th century, was originally plumbed for gas or oil water heating.
Space for the swap in a Lawrence triple-decker
A heat pump water heater needs roughly 700-1,000 cubic feet of surrounding air to pull heat efficiently, and Lawrence's mill-era triple-deckers, some of the densest housing stock in the Merrimack Valley, often have basements built for a squat gas or oil tank rather than that kind of clearance. A gas tankless unit sidesteps the space problem by mounting on a wall and cuts standby heat loss for about 30% lower water-heating energy use, but it isn't eligible for the rebate above, which Mass Save built specifically around electric heat pump units running near 300% efficient.

Common questions
How much is the water heater rebate in Lawrence?
$750 standard, up to $2,250 if your household income is at or below 80% of the area median. Given Lawrence's income profile, many households should expect to qualify for the higher tier.
Is Lawrence's water heater rebate handled by National Grid or Eversource?
National Grid delivers electricity in Lawrence and administers this rebate, while Eversource delivers gas. The dollar amount is set statewide by Mass Save either way.
Does the water heater rebate require a home energy assessment first?
Yes, like other Mass Save rebates it starts with a free home energy assessment to confirm eligibility and your specific rebate tier.
Will a heat pump water heater fit in a Lawrence triple-decker's basement?
Check clearance first. The city's mill-era triple-deckers often have compact basements, and a heat pump water heater needs roughly 700-1,000 cubic feet of surrounding air to run efficiently.
Your utility: National Grid (electric) / Eversource (gas)
National Grid delivers electricity in Lawrence, and Eversource delivers gas, a split worth knowing since a water heater swap typically only touches the electric side. National Grid is who your installer works with if a panel upgrade is needed for the compressor load, and the company periodically runs its own promotions on top of the statewide Mass Save rebate.
