Ideal Insufficient Storage or Reheat Performance

Hot water runs out quickly and takes a long time to reheat on an Ideal storage-type water heater.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed cylinder thermostat, One element of twin-element heater not working, Limescale on immersion heater, Undersized cylinder for demand

Safety: Isolate electrical supply to immersion heaters before inspection.

Check thermostat setting: Ensure the cylinder thermostat is set to the recommended temperature (typically around 60°C).
Test immersion heater(s): A qualified electrician can test continuity and current draw of each element.
Descale immersion: In hard water areas, immersion heaters can become heavily scaled and should be removed and descaled or replaced.
Review usage: If demand has increased (more occupants), consider upgrading to a larger cylinder.
