Clean Heating and Cooling (CH&C) Calculator


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 [insert hyperlink to another page that we need to create with an overview of CH&C technologies] 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.

How to use your summary report

The tool provides a downloadable summary report. Save this report for your records and then play around with the variables in the tool. How do the savings change if you increase the efficiency (i.e. weatherization improvements) of your home or if the price of fuel increases?

Tool outputs

The CH&C calculator results include available state-wide incentives. The annual cost savings reflect the difference between the annual fuel baseline and CH&C energy costs. Cost savings are presented as a value and as a percent. Note that a negative value means that the user will not realize any savings by switching to a CH&C technology.

The annual emissions savings reflect the difference between the current system’s greenhouse gas emissions and the emissions associated (if any) with the CH&C technology.

Simple payback reflects the capital cost of the new CH&C equipment divided by the annual fuel cost savings over time. Note that some CH&C projects can be financed so that there is no initial investment required and thus the payments are smaller than the value of the energy savings. A project financed under these conditions will begin recuperating pay back immediately.
