What does the boost button do on my Gledhill PulsaCoil?

The boost button or switch allows you to heat additional hot water during the day if you run out, using more expensive daytime electricity. It should only be used when needed and not left permanently on.

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.

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.

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.

What should I do if my Gledhill cylinder goes into overheat lockout?

If your cylinder enters overheat lockout, first turn off all heat sources and allow the system to cool completely before attempting any reset. Do not tamper with safety valves or overheat thermostats. If hot water is discharging, turn off the heat source immediately. Some models have a manual reset button on the thermostat, but the cause of the overheat must be investigated by a qualified heating engineer before resetting to prevent recurrence.
