Heat Pump Balance Point Calculator
Calculate thermal capacity and economic switchover points for your HVAC system configuration.
1
Equipment Selection
Select your Bosch heat pump system
2
Building Heat Load

Understanding This Table:
Yellow rows indicate temperatures where the heat pump cannot fully meet the house heating load. Supplemental heating would be required.
⚠
Warning symbol appears when HP capacity is less than the required house load at that temperature.
Heat Pump
/ Gas — Shows which heating source is more cost-effective at each temperature.
Cost comparisons are based on delivering the same amount of heat from both systems for a fair comparison.
