It might have been a hotter than regular winter in Maine, however that doesn’t imply it hasn’t gotten mighty chilly. In mid-January in Farmingdale, a city outdoors Augusta the place Kaylie McLaughlin lives, the temperature dipped to six levels Fahrenheit. “The kind of cold that hurts,” she stated.
But this winter, Ms. McLaughlin’s bungalow is toasty, thanks to 2 warmth pumps she put in to interchange her oil furnace. “I’m just so comfortable,” stated Ms. McLaughlin, a pharmaceutical gross sales consultant. She’s additionally saving cash, now not paying $400 each 4 weeks for an oil supply.

In the summer season, it might probably function in reverse, pulling warmth from inside a constructing and pumping it outdoors, cooling the indoor areas.
In 2023 warmth pumps outsold gasoline furnaces within the United States for the second yr working, a local weather win. Electrical warmth pumps are the most affordable and most vitality environment friendly methods to warmth and funky houses, and they don’t emit the carbon air pollution that’s overheating the planet.
No state has adopted them sooner than Maine.
That northeastern place of hardy sorts and snowbound winters is rapidly going electrical, putting in electrical warmth pumps thrice sooner than the nationwide common, in line with Rewiring America, a nonprofit that promotes widespread electrical adoption. Last September, Maine met its purpose of putting in 100,000 warmth pumps in households two years forward of schedule, and is aiming to put in one other 175,000 by 2027.
Maine’s fast adoption is being spurred by a mixture of state rebates on high of federal incentives and a brand new cadre of distributors and installers, in addition to mounting frustrations over the excessive value of heating oil.
The $12,000 price ticket for Ms. McLaughlin’s warmth pumps was minimize in half by state rebates, and she or he paid for the remaining with low-interest financing. In the coldest months, her mortgage compensation and electrical energy invoice was the identical as her outdated oil invoice, however she’s already saved $100 a month throughout the shoulder season, and gotten a $2,000 federal tax credit score. Plus the warmth is dependable, she stated, in contrast to her rickety outdated oil furnace, which pressured her to spend a lot of the winter bundled up indoors. And although she units the pumps at 66 levels, she stated it feels toastier as a result of the warmth is extra evenly unfold all through her home.
It’s an enormous conversion for a state the place over half the households burned oil for warmth in 2022, the best proportion within the nation.
The change marks a cultural shift, helped when then-governor Paul LePage, a conservative Republican, put in warmth pumps a decade in the past at each his official residence and waterfront house. Word of mouth unfold amongst households, neighbors and even church communities the place new warmth pumps stored congregants heat. Even in frigid temperatures, they informed one another, even in Maine, warmth pumps labored.
“Ten years ago, they weren’t really popular,” stated Josh Tucker, of Valley Home Services, a family-owned heating firm outdoors of Bangor. “No one really knew what they were.” He first put in warmth pumps in his sister’s new house in 2014, over the objections of her constructing contractor who, Mr. Tucker stated, “was against it big time.”
“He thought she was going to freeze to death unless she had a furnace or boiler,” he stated. She didn’t, and makes use of the identical warmth pumps right this moment.
The new expertise was embraced particularly rapidly in a single northern Maine group after Mr. Tucker’s father put in warmth pumps at a Methodist church there. The Tucker household nonetheless sells heating oil and propane, however much less and fewer. Its warmth pump business, in the meantime, grew from putting in two to 3 items per week to three,000 final yr, an almost 20-fold enhance.
“We’ve done TV ads, advertising on social media, but the big one’s always been word of mouth and that’s how it exploded,” Mr. Tucker stated.
According to Efficiency Maine, an unbiased company that runs vitality effectivity applications, changing heating oil and propane with warmth pumps saves a family over a thousand {dollars} a yr.
They may make a dent within the air pollution that’s driving local weather change. By one calculation, if each single household house within the United States adopted warmth pumps, annual greenhouse gasoline emissions would drop by 160 million metric tons, the identical as taking 32 million vehicles off the highway.
Heat pumps carry out considerably of a magic trick. They can take one unit of vitality enter to yield three to 4 items of warmth.
Since nothing is burned, close by air high quality improves. Because warmth pumps don’t use oil or propane, there are not any gasoline leaks. Heat pumps run on electrical energy and in Maine, a lot of that electrical energy comes from wind and different clear sources. In 2022, 64 % of electrical energy generated in Maine got here from renewable vitality.
In a twist, the state’s quick adoption of electrical warmth pumps is expounded to its historic reliance on oil and propane for warmth. Maine is rural and sparsely populated, and gasoline utilities concluded it wasn’t worthwhile to put distribution traces in lots of areas of the state, in line with Michael Stoddard, the manager director of Efficiency Maine. Instead of getting heating gasoline from a utility, Mainers usually have to select up the cellphone to rearrange a supply once they’re working low.
This was one of many causes Michelle Whitmore, 60, a former monogrammer at L.L. Bean, signed up for a pilot program that put in a free warmth pump in her cell house two years in the past. Ms. Whitmore is legally blind, and relied on a neighbor to learn her gasoline gauge. She was additionally bored with having to shovel snow in order that gasoline supply employees might attain her oil tank.
“I figured I couldn’t be any colder with the heat pump than I was with my furnace,” she stated. Now, she simply has to hit a swap. The heating and cooling can be extra constant, she stated, and although her electrical energy payments went up she’s nonetheless saving $200 to $300 a yr.
There has been pushback from the oil and gasoline trade, which has backed campaigns preventing electrification and questioning the efficacy of warmth pumps within the bitter chilly. “Heat pumps have gotten thrown into the culture war of electrification versus staying with fossil fuels,” stated Christopher Kessler, a state consultant from South Portland who works as an vitality auditor. Mr. Kessler stated some house heating contractors who promote each oil and warmth pumps nonetheless erroneously declare that warmth pumps can’t be used as a main heating supply.
Mr. Stoddard of Efficiency Maine stated whereas many Mainers use warmth pumps in tandem with oil and gasoline heating methods, the hybrid strategy reduces the effectiveness of the warmth pump. His company just lately modified its program so solely households that totally convert to warmth pumps get state rebates. People can nonetheless maintain fossil gasoline heating methods however solely as a backup or for family scorching water, he stated.
Smokey Bunn stated he and his household had been paying as much as $600 a month for oil, in addition to going via three tons of wooden pellets for his or her heating range every winter. “It works fantastic,” he stated, of the household’s new warmth pumps. “People that get them rave.”
