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.

Why is water dripping from the tundish on my Gledhill cylinder?

Small amounts of water dripping from the tundish during normal heating cycles is expected, as water expands when heated and the pressure relief valve may release a small amount. However, continuous or heavy discharge indicates a fault condition requiring attention.

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.

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 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.
