2 System description
2.1 Concept of operation
The Hybrid Back-up system consists of the following
components:
- A glow-worm envirosorb 5 heat pump,
- A "Universal" hydraulic module,
- A boiler,
- The Systempro control unit,
- A Climapro2 RF wireless programmable room thermostat,
- A wireless photovoltaic outdoor sensor
The following options may be added to the system:
- 2 port valves for zoning,
- A domestic hot water cylinder
2.1.1 Operating principle of the heating system
- The home's heat is generated by either the heat pump or the
boiler, dependant on outdoor weather conditions, and the
energy prices paid for gas and electricity.
- The software in the Systempro control unit constantly
monitors outdoor temperature, and the co-efficient of
Performance (COP). The control unit then decides when
to switch between the heat pump or the boiler to maintain
comfort levels, whilst maximising the efficiency of the system.
The switchover point must be determined in accordance with
the respective energy costs (see the "Activation of control unit >
Settings> Energy management" chapter).
2.1.2 Operating principle of the domestic hot
water system
The domestic hot water heating circuit consists of a boiler, a 2
port valve and a domestic hot water cylinder.
In order to always obtain the best comfort/economy trade-off,
the heat pump and/or the boiler provide the energy needed to
maintain the stored water at the required temperature.
The lower the hot water temperature setting, the more the
heat pump will provide energy and, therefore, more economic
operation.
