Cala Systems Announces $5.6 Million Seed Round and Makes its Intelligent Heat Pump Water Heater Available for Preorder
Cala Systems (Cala), creator of highly-intelligent heat pump water heaters that ensure comfort, save energy, reduce emissions, and integrate with the home, announced $5.6 million in seed funding and the commercial launch of its product. The round was led by the Massachusetts Clean Energy Center (MassCEC) and Clean Energy Venture Group, and included Burnt Island Ventures, Leap Forward Ventures, CapeVista Capital, Collaborative Fund, and Climate Capital. Cala’s heat pump water heater (HPWH) is now available for preorder on its website, with initial deliveries expected in the first half of 2025.
Cala has developed a highly efficient and intelligent heat pump system that heats water based on the patterns of hot water use in each home and the preferences of the homeowner. By understanding each home’s hot water patterns, Cala improves hot water availability during times of high demand and minimizes costs. In addition, homeowners can tailor water heating to their home and priorities; including synchronizing water heating with the power output of their home solar system, minimizing their greenhouse gas emissions by coordinating water heating with times of clean electricity on the grid, decreasing costs for homes with variable electric rates, preheating water before potential power disruptions, and more.
To achieve this, Cala combines sensors and advanced hardware with patented predictive control software originally developed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). Cala’s predictive controls blend artificial intelligence and physics-based techniques, enabling the system to plan ahead for future hot water use, and whatever other inputs (home solar output, electricity price, etc.) the homeowner has activated in the Cala app. It also incorporates a variable speed compressor and an integrated mixing valve, which enable it to take full advantage of its predictive controls by increasing water heating efficiency and producing more hot water when beneficial.
