2.1.2 Operating principle of the domestic hot water
system
The domestic hot water heating circuit consists of a heat pump,
a 3-way valve and a FLUROCYL hot water tank equipped with an
electric heater.
In order to always obtain the best comfort/economy trade-off ,
the heat pump and/or the FLUROCYL tank electric heater provide
the energy needed to maintain the stored water at the required
temperature.
The lower part of the tank is heated 3 times a day by the heat
pump. In order to provide maximum economy, the electric heater
heats the top part of the tank just to provide the comfort desired
by the user.
The lower the hot water temperature setting, the more the
heat pump will provide energy and, therefore, more economic
operation.
