This application will calculate the ECONOMIC BALANCE POINT temperature of a Heat Pump system with a gas, propane or fuel oil back-up furnace.

*NOTE: Please read this description in full before downloading and using this app.*

This app will help HVAC contractors find the economic balance point to properly set-up a customers dual fuel heat pump system. This does not calculate the Thermal Balance Point which is just as important when setting up a new system. With the high cost of Fuel Oil and Propane and low cost of electric, these systems would likely be set at the Thermal Balance Point.

Before using this app you must have:

the COP47 and COP17 heat ratings for the Heat Pump

the AFUE % of the Furnace

the cost of Electric ($ / kwh)

the cost of Fuel ($ / unit)

DO NOT DOWNLOAD IF YOU DO NOT HAVE ACCESS TO THE ABOVE INFO.

ECONOMIC BALANCE POINT -

the lowest outdoor temperature where the

heat pump, based on current fuel and electric rates, heats at a lower

cost than the furnace.

THERMAL BALANCE POINT -

the outdoor temperature at which the

heating load exactly matches the heating capability of the heat pump.
