Are Gledhill cylinders compatible with heat pumps?

Yes, Gledhill produces the StainlessLite Plus Heat Pump range specifically designed for use with air source or ground source heat pumps, providing mains pressure domestic hot water.

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.

What is the minimum water pressure required for a Gledhill StainlessLite Plus?

For optimum performance, 3 bar pressure and a flow rate of 30 litres per minute is recommended. The appliance will work with lower pressures, however performance will decrease with low flow rate and low pressure.

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.

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.
