This is the best summary I could come up with:

Today’s heat pumps are vastly superior to those deployed decades ago, but one startup thinks there’s still ample room for innovation.

The idea behind the company was hatched when co-founder and CEO Jane Melia was confronted with a dying gas furnace in her “creaky old home in Berkeley.”

That meant two heat pumps running on-demand, a setup that felt inelegant to Melia, an engineer with a doctorate in fluid dynamics.

If she wanted to run either when electricity was cheap or when solar power was plentiful, she’d have to buy a big battery to boot.

The company’s goal to drive down the cost of home electrification has netted it a $4 million early stage round led by Earth Foundry with participation from MUUS Climate Partners, Starshot Capital, and Portfolia, TechCrunch+ has exclusively learned.

Melia and her co-founders “went to the drawing board,” she told TechCrunch+, and came up with a system that integrated a heat pump and a hot water storage tank with “some really, really good controls.”
