So why Cala?

Today’s heat pump water heaters are designed to heat when the water is cold, just like they have been doing for the last 130 years. Cala is designed for more. Our advanced hardware, predictive controls, and sensors look at all the data. We then optimize every variable for maximum efficiency. With Cala, you get a water heater that does more than just the basics.

Cala is a better way to heat water.
Here's how it works:

Easy Setup

Set up your preferences.

After installation, set up your Cala heat pump water heater with our easy-to-use app. Choose your settings, like solar integration, carbon minimization, hours of operation, variable pricing, and more. Cala tailors its heating performance to what matters to you most. Not only is this more efficient but it also means that everything is personalized to you and your hot water needs… all at the tap of a button.

SMART WATER USAGE LEARNING

Cala learns your hot water habits.

Once installed, Cala’s flow sensor immediately starts learning and adapting to your home's unique hot water usage patterns. It tracks how much hot water you use and the times you use it, ensuring optimal performance tailored to your needs. With Cala, your water heater gets smarter every day.
next step
Smart Forecasting

Cala plans ahead for optimal performance.

Using the data and preferences you've set, Cala looks into the future to determine the best times to run, what temperature to heat the water, and the ideal heating speed. This advanced planning allows Cala to adjust its variables to your preferences and usage patterns. This means maximum hot water when you need it. Comfort and efficiency all in one.
next step
Automatic Variable Speed Heating

Cala adjusts heating speed based on time of day and your home’s unique needs.

Cala is the first water heater with a variable speed compressor that adjusts its speed based on your home’s needs. Unlike other heaters that heat at one speed, Cala heats water slowly when demand is low, making it up to 30% more efficient. But, when needed, it can also heat water quickly. For example, when you have an unexpected guest. Cala's innovative compressor ensures optimal performance and saves you money.
next step
Variable Temperature heating

Cala adjusts water temperature to ensure more hot water

Cala’s innovative design allows for an increased capacity of up to 50% by overheating the tank and mixing hot water with cold water at the outlet to a perfect temperature. In contrast, traditional heaters use a mixing valve that requires manual adjustment. Cala adjusts everything automatically based on your preferences and usage. This ensures you have more hot water when you need it, even during regular high demand times.
