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.

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.

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

Economy 7 provides electricity at about half the normal price during the seven hours between midnight and 7am. Your PulsaCoil heats a full tank of water overnight using this low-cost electricity to last you throughout the day.

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.

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.
