Better water heating, by design
For 130 years, water heaters have been designed to heat when the water in the tank is cold. Cala is different. It optimizes water heating based on your home's unique hot water needs - from morning showers to evening baths - while also integrating with solar, batteries, variable electricity pricing and more.
QuitCarbon recommends Cala because it’s the world’s smartest water heating system, with high-tech features designed to keep you comfortable and, most importantly, save you money. Here’s what you can expect:
-
High-tech sensors that learn and adjust to your home’s water usage
-
Up to 50% more hot water during times of peak demand
-
Total savings of up to $750 a year
-
An easy-to-use app that lets you track and control your hot water use
-
The ability to pair with other upgrades, like solar panels, to save even more
For DIY or Pro Install
If you are feeling handy, you can order Cala for delivery to your home, then install it yourself (save $50 with code QuitCarbon50).
Or perhaps you'd prefer a professional installation (with no-cost extended warranty!) - request a referral to a vetted, Cala-certified contractor today.
Either way, you'll get Cala's state-of-the-art heat pump water heater.
