Gledhill PulsaCoil 1 - Punch Bag By Gledhill
Introduction to the PulsaCoil 1
The Gledhill PulsaCoil 1 was first of its kind. Below are videos which will help you better understand how it works and what certain components inside them do.
PulsaCoil 1 - The Punch Bag
Known as the "Punch Bags" due to there outer brown coating the PulsaCoil 1 & 2 resembles a punch bag. There are many PulsaCoil 1 & 2 thermal store systems still in use in London and throughout the U.K. These systems are nearly reaching 20 years of age and nearing the end of the expected lifespan. If you have an original Gledhill PulsaCoil 1 or 2 and it is producing no hot water or very little hot water it could be the immersion elements have failed. It could also be that the immersion element thermostat rods have failed. These two are the most likely cause. In very rear situations the mixing valve itself fails causing just cold water to come out of the taps. In other case we have customers tell us the temperature of the hot water is fluctuating when they come out of the hot water tap. This could be due to the to water level inside the unit or because of the mixing valve. If your Gledhill PulsaCoil 1 0r 2 is producing low hot water pressure at your taps compared to the cold water, the heat exchanger coil inside the unit may be contaminated. If any of these are the case don't worry.

As mentioned early about the Gledhill PulsaCoil 1 & 2 it is reaching the end of its life span. This means the internal cylinder in the unit is leaking. Unfortunately the cylinder cannot be repaired. This would require a Gledhill PulsaCoil replacement.
