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.

How long does a Gledhill cylinder last?

This is heavily dependent on the quality of installation, the way the appliance has been used over the years, and the quality of maintenance and care it has received. With proper maintenance, Gledhill unvented cylinders are backed by a 25-year manufacturer warranty.

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.

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 temperature should my Gledhill cylinder be set to?

Gledhill cylinders should be set to achieve a minimum of 60°C to 65°C. This temperature needs to be achieved regularly to comply with legionella pasteurisation requirements and prevent the growth of harmful bacteria.
