Should I choose copper or stainless steel for my Gledhill cylinder?

Stainless steel is recommended as the superior option when considering durability and reliability, particularly for unvented systems. While copper has excellent heat conductivity, stainless steel has much higher resistance to all forms of corrosion and can withstand higher pressures.

How often should I check the header tank on my Gledhill thermal store?

Gledhill advises checking the header tank water level every three months. The tank should be filled with clean cold water to approximately halfway. Do not overfill as this can cause problems. Ensure the lid is securely replaced to reduce water loss through evaporation. Some units have an optional sight glass fitted to make checking the level easier.

Is the hot water from my Gledhill thermal store safe to drink?

Yes, the hot water delivered through your taps is your mains cold water which has been instantaneously heated by the appliance, ensuring drinking-quality output without stored water exposure.

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.

How does the Economy 7 system work with my Gledhill PulsaCoil?
