Unless you enjoy taking cold showers all the time, water heaters are definitely an essential in every household. With so many different types and brands of water heaters on the market, picking the perfect one can be challenging. Good news – we’re here to guide you with our roundup of the best instant and storage water heaters in Singapore! Still confused about the differences? Read on!
Types of water heaters in Singapore
Storage water heater
When switched on, storage water heaters heat up water stored within an inbuilt tank. The heated water is then drawn out to the tap, while any leftover hot water remains within the tank. Depending on factors such as tank capacity, outside temperatures, and level of insulation, hot water reserved in the tank can last anywhere from a few hours to a couple of days. Most storage water heaters can connect to multiple outlets, and are commonly found outside of the bathroom.
Instant water heater
Also known as tankless or demand-type water heaters, instant water heaters heat up cold water as it flows through the device. Most instant water heaters today are electrically powered, meaning that water is heated using a heating element within the device.
Unlike storage water heaters, instant water heaters do not come with an internal storage tank to store leftover heated water. In addition, most instant water heaters connect to a single outlet instead of multiple outlets, and can be installed within the bathroom.

How do I choose a water heater?
Before you dive right into it, here are some of the most important factors to consider when picking the best water heater in Singapore for your needs!
Before committing to a water heater, make sure you’ve set aside enough space for the device. Storage water heaters tend to be bulkier than instant ones, so the latter might be more suitable for smaller homes. Good news for owners of new BTO flats – they come with a pre-built nook designed to fit a storage water heater!
2. Storage capacity
Another factor to consider is the number of people in your household. While storage water heaters can hold a considerable amount of water, they might not be able to provide sufficient hot water for larger households. If you’re from a large family or have a penchant for taking long showers, an instant water heater might be a more practical option.
3. Number of outlets
The number of outlets you’re planning to connect your water heater to is another factor to consider. Smaller households with only one bathroom should consider installing an instant water heater. On the flip side, a storage water heater would be a better option for those planning to connect your water heater to multiple points within the home. (Note: storage water heaters are the only viable option if you’d like hot water for appliances like sinks and dishwashers.)
In general, storage water heaters will set you back more than instant water heaters. This is largely due to the higher upfront cost and more complex installation process. However, storage water heaters generally boast longer lifespans, and can service multiple outlets within the home. If you’re on a tighter budget or simply don’t require a water heater of such large capacity, instant water heaters are the obvious choice. Our advice? Pick a water heater capable of meeting your needs and lasting through the years – even if it means splurging a little!
Last but not least, you should also take into account lifestyle choices and personal preferences. Storage water heaters are generally known to deliver a more consistent flow of warm water as opposed to instant water heaters, which heat up water only when necessary. If you enjoy taking long, hot showers, choosing a storage water heater would be a no-brainer for you. Those who prize their bathroom aesthetics should also consider storage water heaters, which can be installed in more discreet corners of the house. However, if you’re more interested in an energy-efficient water heater, an instant water heater would be the better option.
How often should a water heater be replaced?
Most water heaters have a lifespan of around eight to 10 years. Factors that affect its lifespan include quality and design, installation location, maintenance schedule, and water quality. Not sure if your water heater is due for a replacement? Here are some signs to look out for:
- Lukewarm or cold water
- Cloudy or rusty water
- Rumbling or hissing noises from the water heater
- Leaking near the water heater
While you might be tempted to try fixing your water heater yourself, we recommend leaving the job to professionals. Improper repair work can lead to undesirable consequences, ranging from drainage issues to even explosions. However, depending on the severity of the issue, a repair job can cost anywhere between $80 to $380. In most cases, you would be better off replacing the appliance entirely!
