What does error code E1 mean on a Gledhill StainlessLite cylinder?

Error E1 on Gledhill StainlessLite cylinders indicates an open circuit sensor fault. The temperature sensor is not connected or has a broken wire.

Are Gledhill cylinders compatible with solar thermal panels?

Yes, Gledhill produces the Torrent SOL range specifically designed for use with solar thermal panels. These models feature a high-efficiency solar coil and can work alongside conventional boilers, providing mains pressure hot water. When solar energy is insufficient, the system automatically reverts to the boiler as the primary heat source. A backup immersion heater is also included for emergency use.

Where can I find the serial number on my Gledhill cylinder?

The 12-digit serial number for unvented cylinders and thermal stores is printed underneath the bar code on the data label or information badge located on the appliance. The first and last digits are spaced slightly away from the rest of the number.

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.

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.

How does the Economy 7 system work with my Gledhill PulsaCoil?
