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.

How long does a Gledhill cylinder last?

This is heavily dependent on the quality of installation, the way the appliance has been used over the years, and the quality of maintenance and care it has received. With proper maintenance, Gledhill unvented cylinders are backed by a 25-year manufacturer warranty.

Where can I find the serial number on my Gledhill cylinder?

The 12-digit serial number for unvented cylinders and thermal stores is printed underneath the bar code on the data label or information badge located on the appliance. The first and last digits are spaced slightly away from the rest of the number.

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.

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.
