If you smell burning, evacuate and contact emergency services. Otherwise, contact a qualified heating engineer to diagnose the issue.

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.

What does error code 48 mean on a Gledhill A-Class system?

Error code 48 on Gledhill A-Class systems indicates the ID resistor has a short circuit. The ID resistor and its wiring need inspection and likely replacement. Contact a qualified heating engineer familiar with Gledhill A-Class systems to diagnose and repair.

Inspect sensor wiring for damage. If wiring appears intact, the sensor is likely faulty. Contact a qualified heating engineer to replace with a Gledhill-approved sensor.

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.

Why are my Gledhill PulsaCoil electricity bills high?

High electricity costs are virtually impossible if the unit is correctly installed and used properly, as units should only heat during off-peak periods unless you manually use the boost function. Check that your boost switch is off and your timer is correctly set to your off-peak hours.

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.

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.

How do I drain my Gledhill cylinder?

To drain the cylinder, first turn off the boiler and immersion heater, then allow the water to cool before proceeding. Open all hot taps in the system and run until cold, then hold open the pressure and temperature relief valve until water stops discharging into the tundish. Open the ball-o-fix isolation valve before the anti-vacuum valve, then open the drain cock and immediately hold open the P&T relief valve again until the cylinder is completely drained.
