Storage Water Heater vs Instant Water Heater

Storage Water Heaters 


Storage water heaters store hot water, insulate it, and reheat them whenever necessary. If you want to save energy and money with storage water heaters, you should make a habit of turning them off whenever it is not in use.

Instant Water Heaters 


Instant water heaters, unlike storage water heaters, do not store and reheat the water. Instant water heaters now have new technology that makes it even more discreet and space-friendlier than storage water heaters. This type of water heater is also cheaper than storage water heaters. However, you should not opt for this option if there are more people using the heater in your home.

Different Types Of Storage Water Heater

Cube-shaped Water Heater


The cube-shaped water heater has been designed differently. It has a beautifully symmetrical design, which makes it look very attractive. If you opt to install this water heater, you will not worry about building a false ceiling just to conceal the heater itself.

Slim Horizontal Cuboid Heaters


Most apartments in Singapore are small in size and so are the bathrooms. However, thanks to the Slim Horizontal Cuboid water heater, you can fit the heater easily even into tight ceiling spaces.

Vertical Storage Water Heaters


Vertical water heaters are known to be much better compared to the other types of storage heaters. This type of water heater makes a great choice for your bathroom in Singapore. The stratification in this case enables you to enjoy more hot water. This is owing to the fact that the surface area in vertical tanks is smaller and thus water gets heated up quickly.

Horizontal Water Heater Tank


The best thing about the horizontal-shaped storage water heater is that it is compact thus, helping save space. This type of water heater is also very safe to use as it is known to shut off automatically.

After knowing the various types of storage water heater and their models available in the market, it is also important to know the general water heater elements before purchasing your storage water heater.

General Water Heater Elements




Storage heater tank

The material of the storage water heater tank should be made from a corrosion-resistant material. The tank material should also be durable and not develop holes.


This insulated storage heater tank will store water in it, which is heated up for use when it is intended to by its user.

Temperature and Pressure valve (TP valve)

When the water in a storage tank is being heated, the T & P valves are used to facilitate the transportation of the build-up pressure. They are designed in the heating system as a precaution from danger.


The thermostat helps to regulate the temperature of the storage water heater.

Pipe and Showerhead

As compared to storage water heaters, instant water heaters do not have tanks. Instead, water is heated through the connection from the pipe to the heater element and output directly to the showerhead.

In addition to knowing the various water heater elements, it is essential to know factors such as features and the functions of a storage water heater when considering the right storage water heater for your home.

Things to Know About Storage Water Heaters

Some useful features of a storage water heater include:

  • Boost Function – Certain storage water heaters come with a boost function that offers you extra warm water when needed.
  • Fan Assist – Generally, auto-combination storage water heaters have a silent fan included that helps in dispelling heat in a much better way.
  • Programmable Heating Schedule – If you have seen a new storage water heater you must have observed it has controls that allow you to select customized heating patterns for different times and days.
  • Size – If the need for hot water in your home is high, then a storage water heater can be the best fit. However, you should be aware of how to choose the right storage water heater size for your home.
  • Thermostatic Controls – Newer types of storage water heaters even have thermostatic controls. These controls will help heat the water to your desired temperature.

If you are still deciding on buying a storage water heater, knowing the pros and cons of a storage water heater can help you decide if you should opt for it.

Storage Water Heater Pros and Cons



In gas water heaters, some of the heat is lost in the form of heated gas, while in electric water heaters, almost all the electrical energy is converted to heat energy. Therefore, this is one of the significance of installing energy efficient water heaters.

easy-maintanence-storage-water-heater-buying-guide-water-heater-city-singaporeEasy Maintenance 

The power source for the electric storage water heaters is electricity and if the wiring is done properly, there is very little maintenance required. In addition to that, newer models of storage water heaters have a maintenance panel at the side, which is easily accessed for maintenance.


Compared to gas-powered water heaters which have additional piping for the gas supply, statistical data indicates that the water heater safety is higher. It is also less likely to develop faults when it uses electrical wiring.

While using the storage water heater and you notice that the water is not hot, you should be aware of the factors which may affect the heating of the water.

water-quality-pros-of-buying-rubine-water-heater-city-singaporeHeating vs Storing

When comparing between a storage water heater and an instant water heater, a storage heater has more heat loss because it stores hot water for a longer period of time.


Even if you have knowledge on how to choose the right size of storage water heater for your needs at home, this can still be inconvenient if you are living in a small house. It will be difficult to find a space in tiny bathrooms to install a bulky storage water heater.

Knowing the pros and cons of a storage water heater may not be enough to help you decide if you should buy it. Therefore, we have listed several factors you should consider before buying a storage water heater for your home.

Things To Consider Before Buying Storage Water Heater


The water heater you will install should be based on the amount of water you need. Consider a storage water heater with a tank capacity of 25 litres (e.g. Rheem EH 25M) if you have a small family. However, for larger families or commercial spaces, consider installing a storage water heater with a capacity of 40 litres (e.g., Rheem EHG 40).

safety-features-rheem-storage-water-heater-buying-guide-water-heater-city-singaporeSafety Features

Ensure that a high-quality thermostat is used to prevent overheating. Additionally, the water heater should also have a pressure and temperature relief valve is that the pressure within the heater remains below the safety limit.

energy-consumption-storage-water-heater-buying-guide-water-heater-city-singaporeEnergy consumption

The energy efficiency of each water heater is specified in the specifications of each water heater. It is advisable to install a quality water heater with higher energy efficiency to avoid higher monthly electricity bills.

The storage water heater with the right size has to be chosen depending on the size of the bathroom where you want to install your storage water heater.

Consider the material of the tank – it should be made from a corrosion-resistant material. The tank material should also be durable and not develop holes.

Mr Kumar was very proactive and genuine in his profession. Others may just change the water heater tank n will leave but mr kumar informed that the flexible host is almost broken n it is dangerous. So he helped to change the flexible host to a stainless steel. He explained very patiently whenever i ask him questions. He was very warm n very helpful. He waited to make sure whether there is any leakage. I am very impressed for he knows what he is doing and also very patient and warm. Very good indeed. 👍
