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.

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.

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.

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.
