The water entering my pool doesn’t feel much warmer
The temperature gain of the water after it has passed through the heater will be di-
rectly proportional to the volume of water being pumped in relationship to the
power output of the heater.
For example: A 6-kW heater, when connected to a 4000-litre per hour pump, will
produce a lift in temperature of approximately 1.2˚C (almost undetectable to the hu-
man hand). However, as the water being heated is recirculated from a single body of
water, the time required to heat it remains unaffected by the volume of flow. A
popular misconception is that slowing down the flow rate will speed up the heating
process.
It is essential that the pipe work connecting to and from the heater has a minimum
bore (internal diameter) of 1¼’’ (32-mm).
Heater sizes 2-kW through to 12-kW are supplied with 2 hosetail adapters which
allow coupling to flexible pipe work. For ease of installation please use the rubber O
rings supplied, simply roll each O ring over the threaded part of the hosetail adapter
before screwing into the heater.
To assist correct air purging and to ensure the heater remains completely full of
water during operation, the return pipe which carries the water back to the pool must
incorporate a safety loop or kick up in the pipe, installed as close as possible to the
heater (see diagram below).
Note: When coupling to flexible pipe a safety loop can simply be created by routing
the pipe up and over an obstacle.
Remember to use pipe clips to securely fasten all hose connections.

ROTECTION
The heater should be installed within a dry weatherproof enclosure.
CAUTION
If the heater is not used during winter months it must be drained to prevent frost
damage.
