Installing a Water Heater in Singapore


We would recommend you to get installation together with your purchase online. Most vendors will contact you or can be contacted to arrange the delivery and installation of the water heater at the same time. Installation costs are separate from the water heater cost. Usually, it is between $80 to $150, depending on the complexity of the installation. For the water heaters we have recommended, the sellers are responsive. So feel free to ask them any questions before you commit to a purchase.


Instant vs Storage Water Heaters


There is always one question when buying or replacing a water heater. Should I buy an instant or storage water heater? Not to worry, let us walk you through the pros and cons of each of them depending on your needs and preferences. After reading, the choice should be clear.


Water temperature and time taken


Instant or also known tankless water heaters are like what their name suggests. Once you turn it on, you’ll be able to enjoy a hot bath within seconds. It will not run out of hot water as long as you keep it on. As the water passes through it, the heating element inside will instantly warm it to the temperatures you want. If you don’t like to wait, an instant water heater is the way to go.


Storage water heaters take time to heat up the water in their tank. Depending on the model, its capacity and how powerful it is, it could range from around 10 to 20 minutes. While you have to wait longer, it does have one advantage in terms of water temperature. It can reach much higher temperatures. If you like very warm baths or need to fill a bathtub, choose a storage water heater.


Water pressure


If you like the feeling of strong water pressure, then go for a storage water heater. Water enters the heater at around 10 litres per minute and is pushed out at a similar intensity. The strong pressure is suitable especially for rain showers. If your storage heater is connected to multiple bathrooms, water pressure may drop when more than one is being used. However, the water pressure is still stronger than an average instant water heater.


Comparatively, the water pressure from an instant water heater is weaker. The water passing through the heater is slowed down so that it has time to be sufficiently heated before being pumped out. As a result, the water pressure is halved. Still, most users will not have any complaints about the water pressure as it is good enough for a satisfying bath.


Some instant water heaters come with a booster pump which helps increase the water pressure. However, this method may be illegal in HDBs if it draws water pressure away from your neighbours. Therefore do check with the seller and HDB before committing to an instant water heater with a pump.




On average, the prices of instant and storage water heaters are pretty similar if you take into account both the water heater and installation costs. On average, most families have 2 bathrooms. They would need 2 instant water heaters which cost around $300 to $450. With installation, the total cost would be about $500 to $600.


If they get a storage water heater, that would cost around $250 to $400. After adding in installation, the cost would also be in the $500 to $600 ballpark.


However, if you are on a tight budget, you should choose an instant water heater. There are lower-end models which cost around $80 to $100. In comparison, storage water heaters have a higher average price with fewer budget-friendly models.


Energy consumption and cost


The short answer is that storage water heaters consume more energy than tankless water heaters. Whenever you turn on the storage water heater, it heats up a large quantity of water. Usually, you will not finish up the entire supply of heated water. That means some energy is wasted in the process.


Instant water heaters are only switched on right before you want to take a bath. It does not need to preheat a whole tank of water. It only heats the water when it passes through. As such, they are much more energy efficient.


On average, storage water heaters use about 1.5 to 2 times more electricity than tankless water heaters.


Space and compactness


Space is a premium in most Singapore homes. Our flats and also our bathrooms have become smaller over the years. That is the reason why instant water heaters have become increasingly popular, especially in HDBs and condominiums. They are slim, sleek and compact with a variety of design aspects to match any bathroom. In terms of size, they only take up around ¼ the space that a storage water heater requires. That is why we recommend most HDB and condo owners to get a instant water heater.


Comparatively, storage water heaters are much larger in size, especially for those with a large water capacity of 35 litres and up. They are usually installed near the ceiling and can be partially covered by a false ceiling. For that reason, smaller bathrooms with low ceilings may feel a little cluttered with a storage water heater. Therefore, storage water heaters are more suited for landed properties or apartments with abundant space.


Installation and replacement


If your home is currently configured with a water heater system, the replacement process is straightforward and prices are lower. That is if you are replacing it with the same type of system (eg. instant to instant). Replacement costs around $80 to $100, depending on which plumber or handyman services you choose.


For new installation and changing of systems (eg. storage to instant), the process is more complicated and costs more.


An instant water heater is the simplest and quickest to install. The main reason is that you do not need to lay new water pipes to other bathrooms. What it needs is an electrical point and a water outlet for it to work. Prices usually range from $100 to $150 depending on the complexity of the installation.


A storage water heater is harder to install. You need to lay new water pipes and install a holder near the ceiling to hold the system in place. The entire installation takes up much more time and also materials which drives up the cost. Prices vary quite a little for such an installation as every scenario is different. Usually, the plumber would get you to send them a picture of your current setup in order to provide you with a quotation. Prices range from $150 to $250 or even more depending on the setup.


We have written a 1700 word article on installing, replacing and repairing water heaters in Singapore. That might be useful for you if you need more information.


Maintenance and upkeep


Water heaters generally have a long lifespan. They can easily last upwards of 8 or more years with regular usage. In terms of maintenance, there is not much that you need to do. Otherwise, all you need to do is to be aware of the common problems that could arise. Some of these issues:

  1. Leakage
  2. Discolouration or contaminated water
  3. Water is too hot
  4. Water is not hot
  5. Low pressure (if previously there was high pressure)
  6. Strange noises from the water heater


Usually, most water heaters are very reliable with many safeguards in place, so you can take your bath in peace and not worry.
