PulsaCoil Original Common Faults

Although many users might assume that a PulsaCoil Original “Punch Bag” thermal store is the same as a conventional hot water cylinder, the only similarity in fact is that they both hold hot water and are heated via immersion heaters. In every other respect, the two are vastly different systems. As such, we have outlined some common faults with the PulsaCoil Original and how you can identify them yourself.

  1. Lack of water in the thermal store. This is generally the result of evaporation, or a leak in either the internal thermal cylinder or immersion heater. If the thermostat has locked open, this can lead to steaming or ‘kettling’ of the system, causing water to evaporate internally in the cylinder, resulting in a lack of hot water at the tap outlets.
  1. Failure of the immersion heater element or thermostat. Failure in either of these components will prevent the system heating up, resulting in a lack of hot water.
  1. Delivery system failure. An issue with the blending valve.
  1. Failure of the external economy-seven time-clock. This can prevent the ‘off peak’ immersion from heating overnight, leaving the internal cylinder cold.

If your PulsaCoil Original is leaking or continually losing water from the header tank, this could be for one of three reasons:

  1. The immersion is leaking. This is a replaceable part which would involve draining down the internal cylinder
  1. Leaking pipework. Generally, if the leak is external to the cylinder then this is repairable, either by tightening or replacing damaged pipework or fittings.
  1. Leaking Cylinder. Unfortunately, this would mean your PulsaCoil Original is beyond economical repair and you require a replacement boiler.

The PulsaCoil Original can either be installed on a traditional off-peak system controlled via the electricity meter or via an external time clock. Time Clocks installed on PulsaCoil Original’s is all installed aftermarket and are not warrantied or included in PulsaCoil Original repairs.

Know how to set your time clock correctly:

◾Economy seven timings are generally set around 12:00 through until 7:00 am

◾Economy ten timings are generally set around 12:00 through until 7:00 am as per economy seven and then an additional top up between 15.00 to until 17:00 pm
