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.

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.

Why don't Gledhill thermal stores need legionella pasteurisation cycles?

Gledhill thermal stores heat mains water instantaneously as it passes through a plate heat exchanger, rather than storing domestic hot water. Since the tap water is never stored within the appliance and is heated on demand, there is no standing water where legionella bacteria could multiply. This design eliminates the need for high-temperature pasteurisation cycles required by traditional stored hot water cylinders.

How does the Economy 7 system work with my Gledhill PulsaCoil?

Economy 7 provides electricity at about half the normal price during the seven hours between midnight and 7am. Your PulsaCoil heats a full tank of water overnight using this low-cost electricity to last you throughout the day.

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.
