2.1 General
Greenline HE is a series of heat pumps that use stored
solar energy in order to provide water-based heating and
hot water.

C6 - C11 are heat pumps with integrated hot water
heaters.
E6 - E17 are heat pumps designed to be supplemented
with an external hot water heater.
Once the heat pump has been installed and started,
there are a number of points that should be checked
regularly. This may concern an alarm triggering or
performing basic maintenance actions. If the problem is
repeated, you should contact the dealer.
2.2 Heat pump function
The heat pump consists of four main parts:
• Evaporator
Evaporates the refrigerant to gas and at the same time
transfers the heat from the collector to the refrigerant
circuit.
• Condenser
Condenses the gas to fluid again and transfers the
heat to the heating system.
• Expansion valve
Lowers the pressure of the refrigerant.
• Compressor
Increases the pressure of the refrigerant.
These four main parts are linked in three circuits. A
refrigerant circulates in the heat pump, which in some
parts of the circuit is in a liquid state and in other parts
in a gas state.
