On Instant and Storage Water Heaters

When choosing a shower heater, there is two broad categories in the market - instant hot water heaters, and storage water heaters. Here's a look at their differences

Instant Water Heater

  • Heats water up instantly as water runs through the equipment
  • Control dial controls the amount of heat transferred to the water
  • Is more limited in how much water could pass through to become heated as water is heated up when the water pipe passes by a heated copper unit - as such, the diameter of the pipe is limited in order to ensure good heat transfer
  • Usually a more fixed design outlook that is combined with a set of shower tap, mixer and shower head
  • Usually not used in low rise landed developments where water pressure is limited by unstable pressure directly from the government supplier


Storage Water Heater

  • Always contains a storage amount of hot water
  • Control dial controls the amount of stored hot water mixed with cold water
  • Is less limited in how much water could pass through to become heated as amount of hot water available is according to the chosen storage tank capacity - as such, a few litres could pass through fairly quickly
  • Could have a varied design by combining with shower tap, mixer and shower heads that are not a set with the storage heater
  • As it has a larger capacity, and could present a more varied aesthetics, used more for upscale developments
  • Usually used in low rise landed developments as stored water ensures better water pressure even if water pressure from the government supplier is unstable
