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.

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.

What gets checked during a Gledhill unvented cylinder service?

A full service assessment includes verifying the installation complies with Part G3 Building Regulations, testing all temperature control functionality, confirming pressure controls and relief valves operate correctly, inspecting critical safety devices, and evaluating overall cylinder condition.

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.

Do I need a scale inhibitor for my Gledhill cylinder in a hard water area?

In areas where water hardness exceeds 200 parts per million (ppm), Gledhill requires appropriate treatment of the incoming cold mains water supply to prevent scale build-up. This may include installation of a water softener or scale-inhibiting device. Failure to install adequate water treatment in hard water areas can impair performance, reduce appliance lifespan, and may affect your warranty coverage.
