1.2 System Conguraons
Mini Heat Pump Monobloc can be congured to run with the electric heater either enabled or disabled and can also be used
in conjuncon with an auxiliary heat source such as a boiler.
The chosen conguraon aects the size of heat pump that is required. Three typical conguraons are described below.
Refer to Figure 1-1.2.
Conguraon 1: Heat pump only
 The heat pump covers the required capacity and no extra heang capacity is necessary.
 Requires selecon of larger capacity heat pump and implies higher inial investment.
 Ideal for new construcon in projects where energy eciency is paramount.
Conguraon 2: Heat pump and backup electric heater
 Heat pump covers the required capacity unl the ambient temperature drops below the point at which the heat pump
is able to provide sucient capacity. When the ambient temperature is below this equilibrium point (as shown in Figure
1-1.2), the backup electric heater supplies the required addional heang capacity.
 Best balance between inial investment and running costs, results in lowest lifecycle cost.
 Ideal for new construcon.
Conguraon 3: Heat pump with auxiliary heat source
 Heat pump covers the required capacity unl the ambient temperature drops below the point at which the heat pump
is able to provide sucient capacity. When the ambient temperature is below this equilibrium point (as shown in Figure
1-1.2), depending on the system sengs, either the auxiliary heat source supplies the required addional heang capacity
or the heat pump does not run and the auxiliary heat source covers the required capacity.
 Enables selecon of lower capacity heat pump.
 Ideal for refurbishments and upgrades.
