Are you installing a water heater for the first time? Water heaters indeed offer tons of benefits for Singaporean homeowners. When searching online, you might have seen or read about storage water heaters and instant water heaters during your search. However, the terms and general explanation may not be enough to let you know more about the two types of water heaters. We will give you an easy-to-understand view of these two types of water heaters before you cash out and subscribe to a water heater installation service. 


Instant Water Heaters


The difference between a storage water heater and an instant water heater is the way they heat water. As the name suggests, water passing through instant water heaters gets warm quickly. They also come in single and multipoint water heater designs run by electricity, while other models use gas. Most water heaters in HDBs and condos in Singapore feature electricity-powered models, which most homeowners find energy-efficient water heaters

Check these brands and types of instant water heaters to help with your next purchase.

Single Point Instant Water Heater

Powered by: Electricity

You can find out if the instant water heater is in a single point design when the water only passes through 1 point to the outlet.

Multipoint Instant Water Heater

Powered by: Electricity

Multipoint water heaters, on the other hand, have various water points before the outlet. 

Gas Instant Water Heater

Powered by: Gas

Unlike the single-point and multi-point water heaters, the third type of instant water heater uses gas to heat water.

Most Singaporean families and professionals live in HDBs rather than a condo and landed property. Between storage vs instant water heater, HDB homeowners prefer the latter for its convenience. According to Everywork’s popular water heater brands, Ariston, Rheem, and Champs are the favorites among HDB homeowners.
