Buying a storage water heater

Available in various sizes and capacities, this type of water heater is ideal if you are looking to supply hot water to multiple points.

Quick tips

  • Measure the amount of space in your bathroom and check it against the dimensions of the water heater before you buy.
  • Cater 10 minutes (estimated) to allow the heating process to complete.
  • Use kitchen and bathroom mixers, not taps, so that hot water can be discharged at the various points.

Factors to consider

A storage water heater maximises your comfort in the shower by maintaining a consistently strong water pressure through the shower head. Consider these 6 factors when deciding which storage water heater is right for you.
