Available at, the calculator allows users enter the energy cost, burner rating, hours of operation per week, normal operating temperature, overall wall area and the horsepower rating of the re-circulation and exhaust blowers. Based on these entries, the calculator estimates hourly and yearly operational cost savings, as well as total savings over a 15-year period.
