What does error code E2 mean on a Gledhill StainlessLite cylinder?

Error E2 on Gledhill StainlessLite cylinders indicates a short circuit sensor fault from damaged wiring or internal sensor failure. Turn off the system and isolate from the electrical supply before any inspection. Inspect sensor wiring for damage, particularly where cables pass through tight spaces or near heat sources. Contact a qualified heating engineer to fit a Gledhill-approved replacement sensor.

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 pressure should the expansion vessel on my Gledhill cylinder be set to?

The air side of the expansion vessel should be set to 3 bar. This must be checked when the system is depressurised and the water is at atmospheric pressure.

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.

What should I do with my Gledhill thermal store when going on holiday?

For absences under 2-3 weeks, keep all power switches on. For longer trips of 3 weeks or more, turn off the off-peak supply but maintain main power to exercise the pump regularly.

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.
