Connecticut Clean Heating and Cooling (CH&C) Calculator

Calculate the potential savings from switching to a CH&C technology and your annual carbon savings with this easy-to-use tool.

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

The tool includes links for more information on the types of CH&C technologies and to heat distribution systems. However, we recommend that you visit this page before using the calculator to learn more about each of the CH&C technologies covered by this tool.

This tool provides an estimated range of savings based on your inputs and using current energy rates by zip code. To get the most accurate estimate, you may want to have both a recent electric and fuel bill in hand. We provide both cost and emissions savings as an estimated range because there are many variables that can affect your actual savings such as the extent of your home’s insulation, the current cost of fuel, the layout of your home and the placement of your new CH&C system, the addition of cooling, and the severity of the winter.

The Connecticut CH&C Calculator was developed by the Clean Energy States Alliance (CESA) in partnership with the Connecticut Green Bank, the Connecticut Department of Energy and Environment, and Avangrid.
