This energy savings calculator is based on one that was developed by the U.S. EPA and U.S. DOE and is provided for estimating purposes only. Actual energy savings may vary based on use and other factors.

Instructions: Please select your fuel type, number of boilers in your home, the rate you pay for gas or oil, and your geographic region.

 
 

Current Boiler

Option 1

Option 2
(obtain the efficiency and capacity from your
boiler rating plate, or use default)
Initial Cost per Unit (estimated retail price)  
Annual Fuel Utilization Efficiency (AFUE)
Heating Capacity of Boiler ** (Btu/hr)
Use with Programmable Thermostat (Yes/No)
** Use input. Usually, boiler size can be decreased if the replacement unit has a higher efficiency.
