Hot Water System Faults

If you are experiencing a lack of hot water please consider these points before requesting maintenance.

No hot water

Please check to ensure all trip switches in the metre box are in the on position, for gas heaters please ensure that the pilot light is lit, all switches in the metre box are turned on and the tap at the main gas metre is turned on.

If the pilot light is not lit please follow the instructions provided just inside the heater flap door.

Hot water keeps turning off or running out

It is common  to receive complaints regarding a lack of hot water only to find that there is no fault with the system

Instantaneous systems:

  • Please always turn the hot water on full and then adjust the temperature to your liking by turning on the cold water.
  • Instantaneous systems require a certain flow of water in order for the heater to switch on. If you have the hot water tap turned on only slightly you may get no hot water or the hot water may cut out a few minutes into your shower.

Storage hot water systems:

  • You may notice a change in the temperature of your hot water, this is often caused by the change in seasons from summer to winter, you may begin to use more hot water as the weather cools down.
  • For units and apartments these dwellings may have small storage hot water systems of around 50 Litres to 60 Litres, an average showerhead may have a water flow of between 5 and 10 Litres per hour therefore this type of system will provide hot water for a shower of 5 to 10 minutes in duration.

Hot water not very hot

  • Your heater may have a temperature dial on the side of the unit which allows you to increase the temperature, you may want to adjust the temperature higher during winter.
  • The heater may be faulty and requires replacement.
