This leads us to another important question….

What type of water heating appliance you have?

You may have any of the following heating system installed in your bathroom:

  • Storage water heaters
  • Electric shower heads (Instant Heaters)
  • POU (point-of-use) water heater
  • Tankless heating system
  • Solar water heater

There are many types of water heaters but Instant Heaters and Storage Tank Heaters are most common in Singapore households. So, let’s compare the two options.

Comparison between Instant Water Heater and Storage Tank Heater

  • Compare the cost of electricity consumed and the heating method. For example; instant heating system costs much less than the storage tank system, but it consumes more electricity.
  • Water consumption (amount of hot water to be used) is another important factor in determining which heating system to purchase. You can do a simple math and calculate how much hot water you need on daily basis.
  • Determine how much hot water you and your family needs on daily basis. If you have a family of 4 members and each of them takes 30 minutes in the shower, the total time of shower will be 2 hours daily.
  • Now compare the electricity consumption of each system. Instant heating system usually consumes 3kw per hour. So, it will consume 6kw. On the other hand, the water stored in storage tank heater will take 2kw/hr. Since water is already stored, it’ll take less energy to heat up. While storage tank is good for large families, instant water is better for 1-2 people since it approximately 1kw daily.
  • Heating methods used in the instant heater and storage-tank heater are different.
  • Storage tank is used to store the water before you switch it on to heat up the water.
  • Instant heater only heats up the water when turned on.

Which is better?

In short, instant water heater is best when you only need a hot water to take a bath. On the other hand, storage water tank is best when you need hot water in the kitchen and bathrooms throughout the day.

Instant heating system is meant to supply hot water in relatively lesser time as compared with a storage tank. Storage tank is better than instant heater in terms of water pressure. As far as durability and lifespan is concerned, storage tank lasts for 5-7 years while instant heating system has a lifespan of 3 – 5 years.
