Why Cala Is a Smarter Kind of
Heat Pump Water Heater

Heat pump water heaters already improve efficiency compared to traditional water heaters by pulling warmth from the air instead of converting the fuel into heat. Cala goes further — predicting demand, adapting to your home's energy systems and prices, and heating water in ways that deliver more hot water when you need it while saving more money.
