Hot water supply
issue
Check another hot water outlet to ensure that
hot water is available.
Mixed water supplies
Water supplies MUST be from the same source:
MUST NOT be gravity hot and mains cold.
Unbalanced water
supplies
For mains fed systems the cold and hot feeds
should be as evenly balanced as possible -
especially for HP unvented systems.
Combination boiler
unable to meet demand
See same cause in 'Fluctuating Water
Temperature' symptom.
Temperature too
hot
Seasonal conditions
In the warmer months, the mains water
temperature can rise to ambient level. The Aqualisa
SmartValve
TM
always blends a mix of both hot and
cold supplies therefore the output temperate at
fully cold (controller setting) will always be higher
than the incoming cold water supply.
Seasonal conditions
(gravity fed systems
only)
For installations which utilise a cold water
storage supply (gravity fed system), the ambient
temperature in the loft can rise to above 40
º
C.
In turn, this warms the stored water. Check by
running a cold tap that is supplied from the water
storage. N.B. Kitchen taps are normally fed from
the mains water system.
Maximum temperature
