Connecticut Clean Heating and Cooling (CH&C) Calculator

This easy-to-use tool allows you to calculate your annual carbon savings and potential savings from switching to a Clean Heating & Cooling technology.

Use the tool below to estimate the greenhouse gas emissions savings and potential cost savings from switching all or a portion of your home’s heat from fuel oil, propane, natural gas, or electric baseboard to a Clean Heating and Cooling solution. You can choose from a variety of Clean Heating and Cooling technologies; the tool covers air source heat pumps, ground-source heat pumps (sometimes called geothermal heat pumps), solar hot water, and heat pump water heaters.

The tool includes links for more information on these technologies and heat-distribution systems. We recommend that you visit Energize CT’s Clean Heating and Cooling page to learn more about each of the technologies covered by this tool.

The tool provides an estimated range of savings based on your inputs and current energy rates in Connecticut. To get the most accurate estimate, you may want to have a recent electricity bill and recent fuel bill in hand. The tool provides both cost and emissions savings as an estimated range, because many variables can affect your actual savings, such as the extent of your home’s insulation, the efficiency of your existing heating system, the current cost of fuel, the layout of your home, and the severity of the winter.
