Climate Technology Product ManufacturingMassachusetts, United States11-50 Employees

Cala Systems is a climate technology product manufacturer based in Somerville, Massachusetts, focused on decarbonizing home water heating. Its intelligent heat pump water heater learns a home's hot-water rhythms and adjusts when, how quickly, and how hot it heats. The system aims to lower energy use and costs while ensuring ample hot water, and it can coordinate with other home energy assets such as solar and batteries. 

Targeted at residential users, the technology addresses the inefficiencies of traditional on/off controls that can waste energy and raise bills. Positioned within the climate technology sector, Cala seeks to reduce greenhouse-gas emissions from household water heating and to align with the growth of renewable electricity. In March 2025, Cala announced the launch of its smart heat pump water heater.
