System diagram
F1145 consists of heat pump, immersion heater, circula-
tion pumps and control system. F1145 is connected to
the brine and heating medium circuits.
In the heat pump evaporator, the brine (water mixed
with anti-freeze, glycol or ethanol) releases its energy to
the refrigerant, which is vaporised in order to be com-
pressed in the compressor. The refrigerant, of which the
temperature has now been raised, is passed to the con-
denser where it gives off its energy to the heating medi-
um circuit and, if necessary, to any docked water heater.
If there is a greater need for heating/hot water than the
compressor can provide there is an integrated immersion
heater.
