We design, manufacture, and sell the world's first intelligent heat pump water heater.

About us

Residential water heating accounts for 3% of all U.S. greenhouse gas emissions and 19% of home energy use, contributing to sky-high bills for many households. We started Cala with the goal to decarbonize home water heating, lower costs, and create a better experience for consumers. So we turned to the source for a better solution: your hot water tank. For the past 130 years, water heaters have been designed to heat the tank when the water gets cold. But we believe it’s time for a change. Cala maximizes the flexibility of your hot water tank by adjusting when, how quickly, and to what temperature your water is heated. Cala heats at the most efficient speed, generates more hot water before periods of high demand, uses electricity when your home solar system is operating or the electric grid is cleanest, and more - all without compromising on comfort. By electrifying water heating and minimizing energy use, Cala significantly reduces greenhouse gas emissions today. And by synchronizing water heating with zero-carbon electricity as it continues to grow, Cala can make every bubble bath, shower, and hand wash a zero-emission comfort in the future. We’re committed to a future where hot water is both a comfort and a step towards a cleaner, more sustainable planet. We hope you’ll join us.

  • Traditional water heaters react. Cala predicts, optimizes, and delivers more hot water when you need it most. Cala delivers up to 50% more hot water by heating to a higher temperature and then mixing with colder water at the outlet to maintain a consistent delivery temperature to your home. This allows Cala to heat more water strategically—before peak demand periods, to avoid high electricity costs, when coordinating with your home solar system, and more. #Cala #WaterHeater #GreenTech #SmartTechnology

    Big shifts are happening in the water heating industry, and heat pump water heaters (HPWHs) are leading the charge. According to Advanced Water Heating Initiative (AWHI)'s 2024 State of the Heat Pump Water Heater Market Report: ▫️ 35% growth in HPWH shipments in 2023—the largest increase in history. ▫️ DOE’s new efficiency standards will phase out electric resistance water heaters over 35 gallons by 2029, making HPWHs the default. ▫️ Market adoption is accelerating, with HPWH sales projected to reach nearly 4 million units by 2030. Water heating is one of the most energy-intensive household needs. Now, smarter technology, better incentives, and electrification policies are driving a market transformation. Is your home’s water heating technology keeping up with the future? #Cala #EnergyEfficiency #HeatPumpWaterHeaters #SustainableTech

  • Cala's intelligent heat pump water heater operates on a simple yet revolutionary principle: instead of using electricity to directly generate heat (like a toaster), it moves heat from the surrounding air and transfers it to the water tank (like a refrigerator in reverse). This process is 2-5 times more efficient than traditional electric or natural gas water heaters, making it a standout option for homeowners who want to save money and reduce their carbon footprint without sacrificing comfort. #Cala #SmartTechnology #WaterHeater #CleanEnergy #SustainableLiving

  • How does Cala's heat pump water heater stack up against traditional systems like natural gas, electric resistance, oil, or propane? Traditional systems convert fuel or electricity directly into heat so they always have a poor efficiency (less than 1) because they can’t produce more heat than the energy they consume. Cala, however, uses electricity to move heat from the air to the water—like an AC or fridge—achieving efficiencies 2-5X higher. The result? Lower bills, a smaller carbon footprint, and no harmful fumes - all things you can feel good about. #Cala #Sustainability #EnergyEfficiency #SmartTechnology

  • Thinking about upgrading to a heat pump water heater? Now's the perfect time, thanks to a variety of rebates and tax incentives that make the switch more affordable. Federal tax credits allow homeowners to claim a portion of the cost on their taxes, while rebate programs offer financial assistance for qualifying households. Many states and local governments also provide incentives to further reduce installation costs. With these opportunities, investing in a heat pump water heater has never been more cost-effective. Check with your local energy office or a tax professional to see which incentives you qualify for and visit our website: https://ow.ly/37C250UEi9g to learn more about costs and savings! #Cala #WaterHeater #SustainableLiving #GreenTech
