SET DHW FLOW & TEMPERATURE
The hot water side of the electrical combination boiler relies on setting the correct ow rate of water going in to
the unit, if the water going in to the unit is too fast then the unit will be unable to cope with the demand and the
water will come out cold. You should aim to set your boiler to approximately the following owrates, you can do
this by restricting the isolation valve tting on the cold water of the inlet during installation.
Rated Boiler Output 7kW 11kW 14.4kW 18kW 21kW 24kW
Recommended Flowrate (LPM) 4 6 8 10 12 13
With the hot water tap open and running the temperature of the hot water outlet can now be set on the boiler by
using the up and down button. The temperature cannot be adjusted without a hot tap being open. Remember
this setting does not guarantee the output, it only sets the maximum possible output, the output temperature will
rely on the ow rate going in to the boiler as above.
