heat pump water heater
Heat pump water heaters are like a refrigerator running in reverse: they use electricity to move heat from the air into your tank. This is the most efficient way to heat your water.

traditional water heater
Traditional water heaters convert fuel into heat, whether that’s electricity, natural gas, propane, or oil. This is a less efficient way to heat your water.

Why Cala?
Today's heat pump water heaters are designed to heat when the water in the tank gets cold—and that's it. We've redesigned the water heater to optimize heating based on your home's unique needs and priorities.
Here's how it works:
STEP 1
Set your preferences
After installation, use the app to set your preferences. Cala will automatically tailor its heating based on what matters to you, whether that's saving money, reducing carbon emissions, synchronizing with solar, and more. And you can easily adjust your settings at any time.
Cala uses its flow sensor to learn your home's unique hot water usage patterns. As these patterns change throughout the day, week, and across seasons, Cala automatically adjusts to ensure optimal comfort and performance.
Based on your hot water habits and preferences, Cala forecasts when to heat water, what temperature to heat to, and how to optimize the compressor’s performance. Cala continually updates its forecast so it’s always using the most recent information.
Cala adjusts heating speed for optimal performance.
Cala is the first water heater that adjusts its heating speed based on future planning. Unlike other heat pump water heaters, Cala heats slowly when demand is low – improving efficiency – and faster when demand is high.
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.
