Is it normal for my Gledhill cylinder to make noise when heating?

Some noise during heating is normal, as the copper cylinder containing 100-200 litres of water will produce sound when heated, similar to a kettle. Noise typically occurs during overnight heating or when using the boost function. However, if noise levels increase noticeably, become excessive, or you hear unusual banging or foghorn sounds, contact a qualified heating engineer to investigate.

What does the boost button do on my Gledhill PulsaCoil?

The boost button or switch allows you to heat additional hot water during the day if you run out, using more expensive daytime electricity. It should only be used when needed and not left permanently on.

Does my Gledhill unvented cylinder need an annual service?

Yes, all Gledhill unvented cylinders require an annual inspection of the key safety devices fitted to the system. This service must be performed by a G3-qualified engineer.

Are Gledhill cylinders compatible with heat pumps?

Yes, Gledhill produces the StainlessLite Plus Heat Pump range specifically designed for use with air source or ground source heat pumps, providing mains pressure domestic hot water.

Why is water dripping from the tundish on my Gledhill cylinder?

Small amounts of water dripping from the tundish during normal heating cycles is expected, as water expands when heated and the pressure relief valve may release a small amount. However, continuous or heavy discharge indicates a fault condition requiring attention.
