Choosing Between Instant Water Heaters vs Storage Water Heaters in Singapore

There are generally 2 types of water heaters: Instant Water Heaters & Storage Water Heaters. In this article, we will go more in depth looking into the difference between these water heaters to provide you with some knowledge on water heaters. If you have already decided between Instant and Storage heaters, please see this article for things to consider when buying a water heater in Singapore.

Instant water heaters

Instant heaters, as the name suggest, instantly heats up the water passing through it. Its less common names are tankless or demand-type water heaters. Most water heaters are run by electricity (either single point or multi-point), while some, although less common in Singapore, are run by gas. Instant water heaters are mostly used by HDBs and Condos in Singapore.

Below are some examples of these types of water heaters:

Single point instant heater

Run by: Electricity

These are called single point instant heaters as the water passes through only 1 point and to the outlet.

Multi-Point Instant Heater

Multi-points instant heater routes the water via various points before the outlet.

Gas Instant Heater

Run by: Gas

Fairly straight forward, these heaters heat up water by gas.
