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.

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.

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.

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 should I do with my Gledhill thermal store when going on holiday?

For absences under 2-3 weeks, keep all power switches on. For longer trips of 3 weeks or more, turn off the off-peak supply but maintain main power to exercise the pump regularly.
