SUPPLEMENTARY HEATING CIRCUIT
FAULT
CAUSE
SOLUTION
The storage cylinder functions incorrectly
or irregularly
Flow rate too high
− Fit a pressure limiter
− Fit a flow reducer
There are blockages or deposits in the
domestic hot water circuit
− Check and clean as necessary
Filling pump
− Check the pump
The water temperature from the boiler is
too low
− Check the setting
There is air in the primary circuit
− Bleed the circuit
SOLAR COLLECTOR CIRCUIT
FAULT
CAUSE
SOLUTION
The storage cylinder functions incorrectly
or irregularly
There is air in the circuit
− Bleed the circuit
The flow rate is too low or too high
− Check the flow rate of the collector
circuit
Pressure is too low
− Check that circuit pressure is approxi-
mately 3 bar when cold
There is lime scale or sludge in the
cylinder
− Check and clean as necessary
The storage cylinder loses a lot of heat
overnight
There is natural circulation to the
