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.

Do Gledhill heat pump cylinders need an immersion heater backup?

Yes, because many heat pumps will not raise the stored water temperature to 60°C (necessary to prevent legionella growth), Gledhill heat pump cylinders are supplied with an immersion heater tapping and thermostat pocket for backup heating.

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.

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.

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.
