What does error code E3 mean on a Gledhill A-Class system?

Error E3 on Gledhill A-Class systems indicates a sensor is reporting a temperature greater than 99°C. Turn off the heat source immediately and allow the system to cool. Do not use hot water until cooled below 60°C. Contact a qualified heating engineer to investigate the cause before resetting.

What does error code 43 mean on a Gledhill A-Class system?

Error code 43 on Gledhill A-Class systems indicates the S6 temperature sensor (store middle) has an open circuit. Turn off the system and isolate from the electrical supply. 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.

What does error code 41 mean on a Gledhill A-Class system?

Error code 41 on Gledhill A-Class systems indicates the S4 temperature sensor (DHW outlet) has an open circuit. Turn off the system and isolate from the electrical supply. Inspect the sensor wiring and connections. If intact, the sensor needs replacing. Contact a qualified heating engineer to fit a Gledhill-approved replacement.

What does error code 44 mean on a Gledhill A-Class system?

Error code 44 on Gledhill A-Class systems indicates the S2 overheat sensor has an open circuit. Turn off the system and isolate from the electrical supply. Check the sensor connections. The overheat sensor must be replaced to restore full safety protection. Contact a qualified heating engineer to fit a genuine Gledhill replacement part.

What does error code 56 mean on a Gledhill A-Class system?

Error code 56 on Gledhill A-Class systems indicates the bottom immersion heater has failed. Turn off the system and isolate from the electrical supply. The bottom immersion heater is the main off-peak heater that heats the entire store. Do not attempt to inspect or replace the heater yourself. Contact a qualified heating engineer to test and replace the immersion heater with a Gledhill-approved part.

Is the hot water from my Gledhill thermal store safe to drink?

Yes, the hot water delivered through your taps is your mains cold water which has been instantaneously heated by the appliance, ensuring drinking-quality output without stored water exposure.

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.

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.

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.

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.
