Operation; Water Temperature Direct Electric Heating - Dimplex Ec-eau Installation And User Instructions Manual

10.2 Operation

Once the system
commissioned, no user intervention
should be required to fully enjoy the
comfort and benefits of the unvented
hot water cylinder.
The hot water temperature can be set
to various requirements. For operation
with a heat pump it is recommended
to set the hot water temperature to
between 45°C and
between 2 and 3 on the dial, please
refer to Figure 12 for approximate
settings). Higher temperatures can
cause tripping of
thermostat, introduce more heat loss
from the unit and increase the risk of
scalding significantly.
When turning on a hot tap for the first
time after a heat up period there
might be a short surge of water. This
is normal in unvented systems and
does not constitute a fault. Sometimes
the water may appear milky – this is
due to very fine air bubbles in the
water which will clear quickly.
