Sexier Heat Pumps Are Hitting the Market

The first Quilt units will be available to San Franciscans in just a few weeks.

Quilt, a climate tech startup banking on the appeal of sleeker, smarter electric heat pumps, announced today that its products will be available to order in the Bay Area starting May 15.

I first wrote about Quilt a year ago after the company raised a $9 million seed round. Its founders told me they wanted to create the Tesla of heat pumps — a climate-friendly product that prevails because of its superior design and performance, with sustainability as a bonus.

“That’s the only way you win, right?” Paul Lambert, Quilt’s CEO said when I visited the company’s office in Redwood City, California, last summer. “You almost need, like, this Trojan horse. You need to be able to convince people who are skeptical. It needs to be better on its own merits.”

Conventional heaters generate warmth by burning fuel, whereas heat pumps transfer it using electricity. They come in two main form factors: a central system, which conditions the air throughout a building via ducts and vents, with machinery that can be hidden away in the attic or basement; and a mini-split, a room-by-room solution that typically looks like a white, oblong, plastic box mounted on the wall. Quilt is redesigning the latter.

The company won’t release full product images until the launch in May, but a new teaser released today shows a mini-split peeking from the edge of the frame with blonde wood paneling to match the wood of other furniture in the room.

The company also revamped the outdoor component of the mini-split, which typically looks like an industrial metal fan.

Quilt just closed a $33 million series A funding round led by climate venture heavyweights Energy Impact Partners and Galvanize Climate Solutions, which will help get it through its launch and initial expansion.

The company is promising a lot — not just a more customizable and aesthetically pleasing product, but also improvements on efficiency and comfort, smarter software, and a better customer experience beginning with the point of purchase. Quilt is limiting its launch to the Bay Area because that’s “where the bulk of our team is on the ground to support homeowners through the purchase, install, and rebate process,” Lambert told me in an email this week. “Los Angeles will follow soon after and then we’ll use our waitlist to guide our expansion.” He said there were already thousands of interested homeowners on the waitlist.

Though there’s certainly evidence that homeowners want a nicer looking product and an easier installation experience, the biggest hurdle to heat pump adoption is that they are far more expensive than natural gas heating systems. Lambert wasn’t ready to share how much the system would cost, but promised it would be “priced competitively and transparently.”

At such a small scale, it’s likely that Quilt will join the ranks of other luxury decarb products, like the Impulse Labs induction stove — at least to start. But the company has high hopes. “Our goal is to get Quilt into as many homes as possible to supercharge the clean energy transition and to meet rising demand for a smart, intuitive, design-forward heat pump,” Lambert said.

We’re Worrying About Hurricanes Wrong

Don’t look at the number of forecasted storms and panic. But don’t get complacent, either.

When is an announcement less an announcement than a confirmation?

The National Oceanic and Atmospheric Administration’s 2024 hurricane season outlook, issued Thursday morning, might be one such case. For the past several weeks, hurricane agencies around the country have been warning of an extremely active, potentially historic season due to a confluence of factors including the record-warm water in the Atlantic Main Development Region and the likely start of a La Niña, which will make the wind conditions more favorable to Atlantic storm formation. With the Atlantic Hurricane Season set to start a week from Saturday, on June 1, NOAA has at last issued its own warning: There is an 85% chance of an above-average season, with eight to 13 hurricanes and four to seven of those expected to be “major” Category 3 or greater storms.

A Carbon Border Adjustment Is Gaining Bipartisan Ground

If you haven’t already, get to know the “border adjustment.”

While climate policy has become increasingly partisan, there also exists a strange, improbably robust bipartisan coalition raising support for something like a carbon tax.

There are lots of different bills and approaches floating out there, but the most popular is the “border adjustment” tax, basically an emissions-based tariff, which, as a concept, is uniquely suited to resolve two brewing trade issues. One is the European Union’s Carbon Border Adjustment Mechanism, which will force essentially everybody else to play by its carbon pricing system. Then there’s the fact that China powers its world-beating export machine with coal, plugged into an electrical grid that is far dirtier than America’s.

It Took More Than 4 Days to Put Out This Battery Fire

The California energy storage facility is just a short hop from the Mexican border.

A fire at a battery storage site in San Diego County appears to have been extinguished after burning on and off for multiple days and nights.

“There is no visible smoke or active fire at the scene,” Cal Fire, the state fire protection agency, said in an update Monday morning.
