How Does Cala Compare to Other Water Heaters?

Cala provides greater annual savings and the lowest carbon footprint of any water heater.
Electric Resistance
At U.S. average electricity prices, a family of four will save over $520 per year with Cala and reduce their CO2 emissions by 75%.
Oil or Propane
For a family of four, Cala saves $475 per year based on average electricity and propane prices and reduces water heating carbon emissions by up to 55%. Cala saves about $380 per year versus oil.
Natural Gas (Tank)
Cala saves a family of four about $200 per year compared to a natural gas water heater in certain states, including Arizona and Massachusetts. However, the prices of natural gas and electricity vary widely from state to state, so the costs and savings do, too. We’ll be providing more information here over time, so reserve your unit or subscribe below if you’d like to learn more.
