Savings Calculator Instructions
Water Heater Calculator:
- Select the number of people in your household.
- Select the type of current equipment.
- Select the efficiency, or Uniform Energy Factor (UEF), of your current water heater. The UEF is typically found on the specification sheet provided with your water heater. If you don’t know the UEF of your water heater, select “Standard” to compare all high-efficiency options. “Standard” represents the current minimum efficiency allowed by code.
- Select the Capacity of your current furnace. If you don’t know the capacity of your furnace, for estimating purposes, you can use 50 BTU per square foot.
(For example: 2,000 square foot home * 50 BTU = 100,000 BTU furnace)
- Select the efficiency, or AFUE (Annual Fuel Utilization Efficiency), of your current furnace. The capacity and AFUE is typically presented on a sticker on the furnace. If you don’t know the AFUE of your current equipment, select “Standard” to compare all high-efficiency options. “Standard” represents common efficiency of standard equipment.
