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.

What should I do if my Gledhill cylinder goes into overheat lockout?

If your cylinder enters overheat lockout, first turn off all heat sources and allow the system to cool completely before attempting any reset. Do not tamper with safety valves or overheat thermostats. If hot water is discharging, turn off the heat source immediately. Some models have a manual reset button on the thermostat, but the cause of the overheat must be investigated by a qualified heating engineer before resetting to prevent recurrence.

How long does a Gledhill cylinder last?
