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.

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.

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.

Are Gledhill cylinders compatible with solar thermal panels?

Yes, Gledhill produces the Torrent SOL range specifically designed for use with solar thermal panels. These models feature a high-efficiency solar coil and can work alongside conventional boilers, providing mains pressure hot water. When solar energy is insufficient, the system automatically reverts to the boiler as the primary heat source. A backup immersion heater is also included for emergency use.

Should I choose a vented or unvented Gledhill cylinder?

Choose a vented cylinder if budget is your primary concern or you need a reliable replacement for an existing system. Choose an unvented cylinder if space constraints exist or consistent high-pressure hot water is essential throughout your home.
