PulsaCoil PCS Common Faults

The Pulsacoils PCS from Gledhill with a stainless steel internal tank is also known as the “Pulsacoil PCS ECO.” All earlier models had pinhole-leak-prone copper thermal cylinders storing the water within. Due to the urea-formaldehyde foam and riveted external steel shell blocking access to the inner copper tank, these leaks could not be fixed. This meant that the only way to fix any pinhole leaks on the cylinder was to buy a brand-new appliance.

By using a stainless steel inner tank in place of a copper one, the Pulsacoil PCS thermal stores solve this issue. Only time will tell if these last longer than the versions with copper tanks, but thus far, things are looking fine. A Pulsacoil Stainless with pinholes has yet to be seen.

The exterior case and internal stainless steel cylinder, heat exchanger, and heater elements of the PulsaCoil PCS ECO model look to be identical to those of the original PulsaCoil Stainless model, however, the pump, circuit board, and water flow/temperature sensors are entirely different. A small circuit board now controls a low-energy pump and a sophisticated flow sensor with no moving components in place of two heat sensors, a Grundfos pump, and a huge circuit board. Despite the fact that there appears to be no temperature reader, it all seems to operate well – most of the time. The tap water temperature is kept at a constant level, and the pump is cut off as expected when a hot water demand ends.
