Former Tesla exec and Heron Power CEO Drew Baglino has founded a heat pump startup - BERITAJA

Former Tesla executive Drew Baglino has softly founded a power pump startup, TechCrunch has learned.

This is the 2nd institution founded by Baglino successful the 2 years since he near Tesla. Sources confirmed the beingness of the startup, called Sadi Thermal Machines, and TechCrunch has reviewed institution filings successful Delaware and California.

Sadi was formed successful June 2025 and shares its Scotts Valley, California, office pinch Heron Power, a startup besides founded by Baglino, that sells solid-state transformers, according to institution filings.

The sanction of the institution is an evident reference to Nicolas Léonard Sadi Carnot, a pioneering French physicist whose activity formed the instauration of modern thermodynamics, including the soul combustion motor and the power pump. Little is known about Sadi Thermal Machines, however, it appears to employment respective Tesla alumni, according to a reappraisal of LinkedIn and a root acquainted pinch the startup.

TechCrunch was incapable to scope Baglino aliases the PR patient that represents Heron Power. This article will beryllium updated if they respond.

Before founding Heron Power and Sadi Thermal Machines, Baglino spent about 2 decades astatine Tesla, wherever he worked connected everything from the original Roadster to the Powerwall and Powerpack power retention systems. When Baglino left Tesla successful April 2024, he had risen to elder vice president, overseeing the improvement of the company’s halfway power technologies, including electrical motors, batteries, and powerfulness electronics.

Along the way, Baglino worked connected Tesla’s power pumps. He’s cited arsenic an inventor connected a patent for a thermal guidance strategy that operates 2 coolant loops, 1 to cool the artillery and different to cool drivetrain components.

To negociate the 2 loops, Baglino and his teammates developed three-way and four-way valves that springiness an EV’s thermal guidance strategy much blase power complete the somesthesia of various components. Such a strategy allows Tesla to harvest power from the traction motor, for example, and usage it to pre-heat the artillery to guarantee optimal capacity erstwhile accelerated charging successful acold weather.

The patent lays retired immoderate of the creation principles that shape the ground of Tesla’s “octovalve” strategy that first appeared successful the Model Y. The power pump successful that conveyance manages the somesthesia of the cabin, batteries, and motors, each successful a package that’s about the size of a suitcase.

When it debuted, Tesla’s octovalve strategy was much precocious than that of its competitors, and for astatine slightest a little period, the institution considered processing a power pump for residential and commercialized settings. Tesla executives, including Baglino and CEO Elon Musk, mused connected specified a strategy during an earnings call successful 2022. They discussed a power pump that would grip some HVAC and h2o heating.

“From a ngo perspective, it’s very aligned,” Baglino said. “We person learned a batch about really to make could and reliable power pumps that activity successful each biology conditions and are excited about the thought of moving connected that problem 1 day. Let maine put it that way, it’s decidedly aligned pinch our ngo to accelerate the modulation to sustainable energy.”

Making a power pump for the home, he added, would beryllium easier. “Way harder successful a vehicle,” he said. “It’s truthful constrained connected wide and measurement and energy.”

But Musk past added 1 of his celebrated qualifiers. “It is simply a point we will do, but we’re not committing to a clip framework astatine this point,” he said. Tesla has yet to merchandise a residential HVAC aliases h2o heating system.

“People should do it anyway,” Baglino said connected the call. With Sadi Thermal Machines, he appears poised to make bully connected that statement.
