What temperature should my Gledhill cylinder be set to?

Gledhill cylinders should be set to achieve a minimum of 60°C to 65°C. This temperature needs to be achieved regularly to comply with legionella pasteurisation requirements and prevent the growth of harmful bacteria.

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.

Can I leave my Gledhill thermal store switched off for extended periods?

Gledhill does not recommend leaving your unit switched off for prolonged periods without draining it. If the water in the copper cylinder remains cool for an extended time, the natural rate of corrosion accelerates, reducing the appliance lifespan. Additionally, if power is off, the pump is not exercised regularly and may seize. If you need to leave your property for several months, have the unit professionally drained.

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.

Do I need a scale inhibitor for my Gledhill cylinder in a hard water area?

In areas where water hardness exceeds 200 parts per million (ppm), Gledhill requires appropriate treatment of the incoming cold mains water supply to prevent scale build-up. This may include installation of a water softener or scale-inhibiting device. Failure to install adequate water treatment in hard water areas can impair performance, reduce appliance lifespan, and may affect your warranty coverage.
