Pulsacoil III
The Pulsacoil III was the first Gledhill product that incorporated a printed circuit board. The PCB controlled the speed of the pump to ensure that the flow through the external plate heat exchanger produced a constant water temperature at the taps. The store is heated via the bottom emersion, usually overnight on an economy tariff. A top emersion is supplied as back up or as a boost facility that can be operated during the day.
One of the more common causes of failure on the Pulsacoil III is low water level in the expansion tank. This can easily be resolved by topping up the tank with a jug for example and ensuring the lid is securely fastened.
Common Faults
Another common fault is a failure to the hot water flow sensors. This seems to happen more often on units that have overheated due to low water level.
The Pulsacoil III is fitted with two emersion elements. In our experience these last approximately 5 to 7 years, depending on their use and the hardness of the water. Changing the elements is one of the more expensive jobs due to the system having to be fully drained to allow for this to be carried out.
If you are experiencing any of the problems mentioned or would like help with your Pulsacoil then please call our helpline and book one of our qualified engineers to carry out a full investigation or to give a quotation for any repairs required.
Warning!!
Pulsacoils can produce very high electrical currents, if you suspect that there is an electrical fault, switch off the unit at the isolation switches and call our helpline for advice. Only fully qualified electrical engineers, NICEIC or equivalent should carry out work on any electrical appliance. DO NOT attempt to repair the unit yourself as an electrical shock could prove fatal!
