This free calculator is provided as a reference tool and is intended to estimate costs and savings based on current rates and customer supplied inputs for a full heating load installation. Actual costs and savings may vary and are highly dependent on a range of factors including, but not limited to: vendor, home construction, terrain composition, incentive eligibility, age of existing system, efficiency of selected system, etc.
This tool uses simplified assumptions based on information from the following sources: Heat Pumps Potential for Energy Savings in New York State – NYSERDA Report, Gas Conversion Customer Proposals (Adjusted from Trade Ally Estimates), Ground Source Heat Pump Rebate – NYSERDA, Residential Renewable Energy Tax Credit – ENERGY.GOV, Emissions & Generation Resource Integrated Database (eGRID) – US EPA, NY Technical Resource Manual, Version 6
