Your Guide to Buying Water Heaters in Singapore

Water heaters are essential equipment for any household. They provide hot water for shower, dishes, and laundry. If you are in the market for one, do consider the following points below to help you choose the right water heater for your needs.

Types of water heaters

There are two variants of water heaters – tank and tankless models. Although tankless water heaters are a popular choice, conventional tank variants still have their uses and advantages.

  • Tank water heater - It comes with an insulating material to keep the water warm inside the tank. It also has a thermostat that allows you to control the temperature of the water. Tank water heaters can either be gas or electric.
  • Tankless water heater - Unlike tank water heaters, tankless variants provide an unlimited supply of hot water. Plus, they are comfortable, convenient, and energy-efficient.

Things to consider when looking for water heaters

Before you buy a water heater, it’s important to consider the following points below. Also, make sure the one of interest to you suits your needs, should be longer-lasting, and above all provide value for your money.

Energy Efficient

If you’re looking for an energy-efficient water heater, then a tankless variant is your best bet. It supplies hot water only at the time it is being used. Thus, it will expend less energy and therefore will save you money on the electricity bill each month. When looking for a water heater, check if it has a high energy factor. The higher the energy factor, the more efficient the water heater will be. Moreover, if you are going for tankless water heaters, expect them to be priced higher compared to the standard tank variants.


Tank water heaters are often bulky in size which uses up a lot of space in your house. They are ideal if you have a large space where you can put them. Meanwhile, tankless water heaters do not take up much space, unlike the regular tanks since they are compact.


In terms of longevity, tankless water heaters win over conventional tank heaters. This is because the latter is subject to wear and tear. A tankless water heater has a lifespan of 20 years, while a tank variant has 10-15 years. Another great thing about a tankless water heater is that its parts are replaceable, allowing you to extend its life.

Storage capacity

In this category, the tank water heaters win hands down. They can store over 150 litres of hot water, more than enough to accomplish your laundry, kitchen, and bathroom related needs. Whereas, tankless water heaters can provide a few litres of hot water at a time.


Tankless water heaters cost more since they require electrical outlets in order for their internal components to function. It also needs better gas pipes and a ventilation system. But, in the long run, you can make up for their high initial price as you consume less energy and reduce your electric bill, thus, saving you a lot of money.

Which is Better: Storage Water Heater or Instant Water Heater?

A storage water heater heats water in large volume, hence taking up a longer time for the water to be fully heated up. On the other hand, an instant water heater heats water instantly through a tiny heating chamber right after being powered up. Many households usually opt for instant water heaters these days due to their energy efficiency and shorter time taken to get heated water. Overall, if your home has limited space and you would like to lower electricity costs, an instant water heater is the ideal option.

How long does a water heater last?

The average lifespan of an instant water heater is between 5 and 7 years, whereas a storage water heater can last approximately 10 years or more. That said, it’s crucial to do a proper inspection and maintenance for your water heater every 3 years.

When should I replace my water heater?

Although some water heaters are still functioning well after 5 years, there may be hidden problems that we don’t notice while we shower. Here are some telltale signs of a water heater needing a replacement:

  • Water leakage: If your heater is leaking water, it is possibly due to cracked or loosened water piping. Contact a plumber to assist you in fixing the pipe.
  • Brown water: Water that flows out appears brown or weird in colour, which indicates that there’s rust in the internal components of your heater. This murky water is detrimental to your skin, so it requires an immediate replacement.
  • Inconsistent water temperature: If the water temperature often turns from hot to cold and cold to hot by itself, the thermostat might be faulty.
  • Weird noises: Water heaters are generally quiet, so if yours is starting to make some strange noises, that means there are accumulated sediments in the water heater, causing it to work even harder to heat up the water.
