Possible cause 3:
Insufficient flow.
Remedy: If the display is flashing ‘noF’ the flow rate has dropped below
the minimum level or has stopped completely. The cause of the reduced /
static flow rate should be investigated and resolved.
Also check that the flow switch paddle is not obstructed/being held in the
‘off’ position.
General Trouble Shooting
NO LIGHT APPEARS ON THE HEATER WHEN IT IS SWITCHED ’ON’
Possible cause:
Power failure external to the heater
Remedy: Check any fuses, RCD or other switch components installed in
the supply cable.
Note:
the heater is not fitted with a fuse.
THE FLOW TUBE DOES NOT FEEL WARM
Due to the high efficiency of your electric heater no warmth should be
detectable from the flow tube of the heater.
The most likely causes of the flow tube feeling warm are:-
Possible cause 1: The heater has been positioned in direct sunlight.
Possible cause 2:
An air pocket is trapped inside the heater particularly if
the tank feels warmer at the highest point of the tank (as air rises).
THE WATER ENTERING MY POND DOES NOT FEEL MUCH WARMER
The temperature gain of the water after it has passed through the heater
will be directly 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 4,000 litre / hour
pump, will produce a lift in temperature of approximately 1.2°C (almost
undetectable to the human hand) however, as the water being heated is
re-circulated 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.
