Please review this section. Although
there are no user serviceable
components in the water heater, the
information contained in this section
may enable you to avoid the cost of a
service call.
Please do not remove any covers or
attempt to make any adjustments.
Principle of Operation:
A heat pump storage water heater works
in a similar way to a reverse cycle air
conditioner. Heat is extracted from the
outside air and transferred to the water in
the storage tank. It does not need to be
located in direct sunlight to work.
A heat pump storage water heater can
efficiently produce hot water on cloudy
and overcast days as well as during the
night.
The length of time that the water heater
will run each day will vary depending on
the amount of hot water being used and
the ambient temperature and humidity.
Generally, the water heater will run
longer in winter and at night when
the air is cooler (and so contains less
energy).
The Hotlogic
®
controller monitors the
water temperature and the ambient
air temperature. Providing the ambient
conditions are suitable, when the water
temperature drops below 55°C, the
Hotlogic
®
controller starts the heat
pump module.
Depending on the humidity level, ice
may begin to form at around 5°C.
This has the potential to affect the
performance of the water heater.
The Hotlogic
®
controller monitors the
ambient conditions and triggers a de-
icing cycle if required.
Water Discharge from
Condensation Drain Line:
Water may be expected to drain from
the Condensate Drain Line when
the water heater is operating. This is
similar to the condensation produced
by an air conditioner. The amount of
condensation produced will depend on
ambient conditions such as temperature
and humidity.
No Hot Water:
Ensure the power supply circuit breaker
has not “tripped”. If the water heater
is connected to a controlled load tariff,
ensure this is operating correctly.
