Does The Heat Pump Need Sun-
light To Operate?
Heat pump water heaters extract their
energy from the surrounding air and
not from sunlight. For this reason they
can efficiently produce hot water any
time day or night and even on cloudy or
overcast days. It is not uncommon for
your system to operate during the night.
Caution: All water heaters have
the ability to produce hot water
in a surprisingly short time.
To reduce the risk of scald
injury, it is mandatory under
the requirements of Australian
Standards AS3500 that an
Australian Standards approved
temperature control valve be
fitted to the hot water supply
pipe work. This valve should
be checked at regular intervals
to ensure its operation and
settings remain correct.
Why Is There Condensation Com-
ing From The Unit?
Condensation production is normal
for all devices that use refrigeration
principles. Air conditioners are a good
example of systems that produce water
condensation.
Condensation occurs when relatively
warm moist air passes through the cold
evaporator. Moisture contained in the air
condenses (deposits) onto the evaporator
fins, then runs down into the drainage

system located under the evaporator. It is
this water that you see flowing from the
condensate drain of the system.
The amount of condensation will vary
with the humidity of the location, so the
amount of condensate that flows from
the module will also vary.
When condensate is created, it runs
into the "Condensate Tray" which sits
on top of the storage tank. This then
runs out through the "Condensate
Drain" which is a feature of the tray.
A plastic drain pipe is attached to this
drain allowing easy access for the
plumber to attach the condensate drain
line away from the heater. The louvre
incorporates a condensate drain cover,
to offer protection to the drain.
