We’re on a mission to decarbonize every tap.

Transform the way you experience hot water with Cala’s advanced heat pump water heater technology. Never compromise on efficiency, sustainability, or cost savings ever again. Our aim is to lead the way in decarbonization through innovation.

The ultimate goal? Make every bubble bath, every hot shower, and every hand wash a zero-emission comfort. Feel good about your hot water knowing you’re making a positive impact on the planet without impacting your budget.

We’re a team of seasoned engineers and industry professionals — Experts in water heating technology, energy markets, the electric grid, consumer hardware, and building products.

We had one mission in mind when we started Cala: decarbonize domestic hot water without anyone having to sacrifice on comfort or convenience. We want to save you money while saving the planet too. And that feels good.

We handle everything from turning wrenches to programming software. We understand the technicalities of fluid and thermal sciences. And we know how to navigate the complexities of the electric grid and energy markets. We believe in creating a better, more sustainable future with every drop of hot water.
