2. System Configurations
R32 Split Type Air Source heat pump unit can be configured to run with the electric heater either enabled
or disabled and can also be used in conjunction with an auxiliary heat source such as a boiler.
The chosen configuration affects the size of heat pump that is required. Three typical configurations
are described below.
Configuration 1: Heat pump only
 The heat pump covers the required capacity and no extra heating capacity is necessary.
 Requires selection of larger capacity heat pump and implies higher initial investment.
 Ideal for new construction in projects where energy efficiency is paramount
Configuration 2: Heat pump and backup electric heater

Heat pump covers the required capacity until the ambient temperature drops below the point at which the heat
pump is able to provide sufficient capacity. When the ambient temperature is below this equilibrium point, the
backup electric heater supplies the required additional heating capacity
 Best balance between initial investment and running costs, results in lowest lifecycle cost
 Ideal for new construction.
Configuration 3:Heat pump conjunction with auxiliary heat source
 Heat pump covers the required capacity until the ambient temperature drops below the point at which the heat
pump is able to provide sufficient capacity. When the ambient temperature is below this equilibrium point,
depending on the system settings, either the auxiliary heat source supplies the required additional heating
capacity or the heat pump does not run and the auxiliary heat source covers the required capacity.
 Enables selection of lower capacity heat pump.
 Ideal for refurbishments and upgrades.
