How Do I Select Between Storage and Instant Water Heaters?

A storage water heater heats up cold water and stores it in its insulated tank to keep it warm for a period of time. It also reheats it occasionally when the temperature drops.

As a result, a storage water heater typically uses up more energy than an instant water heater.

Storage heaters also take up a lot of space due to its bulky size, capable of storing 30 to 100 litres of water.  Instant water heaters are more compact and heats up water on-demand. 

Whether you choose an instant or a storage water heater mostly depends on your budget, your household’s water consumption, your showering habits, and your preferred bathroom aesthetic.

7 Signs You Need A New Water Heater Installed

One of the most used appliances in Singapore is the water heater. With overtime use of instant water heaters or storage water heaters, they can malfunction and lead to costly repairs – especially if your installed water heater is working for more than 8 or 10 years.

Below are the 7 Signs you need a new water heater installed.

Water Heater Is Leaking

An indication to replace or repair your water heater is when it has issues like water heater leakage. Water heater leakage can damage the interior of your bathroom – here are some signs you can identify if your water heater is leaking.

Water Heater Is Too Old


Properly and well-maintained water heaters are said to last for at least eight to ten years. The lifespan of an installed water heater also depends on how often you use it.

Water Heater Emits Odd Noises


After the water heater has been used for several years, mineral deposits are formed inside the installed instant water heater. Usually, the minerals dissolved solids in the water, making a noise when the water is heated.

Water Heater Produces Rusty Water

Most water heaters are designed using corrosion-resistant materials, but they degrade after several years and may cause rusty water if it becomes corroded.

Each instant or storage water heater has a thermostat that regulates the water heater’s heating, and it is sufficiently hot with a preset temperature of 60°C.

Thermostat Issues


Each instant or storage water heater has a thermostat that regulates the water heater’s heating. When the water produced is not hot enough, it indicates that the thermostat is not working correctly and has water heater issues.

Lack of Hot Water

In most cases, the installed water heater will stop producing hot water if the heating element in the heater is damaged. Suppose there is no water from the heater. In that case, mineral deposits in the water heater could affect the flow of water.

When your water heater is showing any of the signs mentioned above, consider replacing it with an energy efficient water heater.

Repairing faulty faucets


The presence of dripping taps can lead to the wastage of large volumes of water and an increase in the water bill. There are several things that can result in water wastage with your water heater – like faulty showerheads or dripping taps.
