When looking for water heaters, there are usually some factors that come to mind: “What type of water heater should I get?”, “What brand of water heater works best?” and more. In this article, we will bring you through some of the key points to consider, when buying a new water heater. Whether we are looking for an instant or storage heater, there are still a few things that we have to consider. So below are a few main pointers you may want to take note of.



Types of water heater

First things first, you have to understand that there are generally 2 types of water heater, namely: Instant heater and Storage heater.

Instant heaters, as the name suggests, instantly heat up the water passing through them whereas Storage heaters are heaters that have an insulated tank, and the water is heated from within before usage.

When it comes to buying products, as an economically-conscious consumer, the cost would most definitely come to mind. “How much could a water heater cost?” Well, depending on the model and brand you choose, the price would most definitely be different. Brands such as Ariston are generally more expensive than compared to brands such as champs. Ariston believes in providing quality water heaters that are worth every of your penny whereas brands such as Champs are more economical for users on a budget but do not sacrifice their proficiency. Instant water heaters are also generally cheaper than compared to storage water heaters.


Instant heaters are small and compact; thus, it does not use up much space compared to storage heaters. The most common practice for instant heater installation is for it to be wall-hung in the bathroom for convenient use. It is best to position the instant heater near an existing power line so as to not incur extra costs for extensions. Water Heater City Singapore provides such installation fuss-free, for your ease of mind.



Instant heaters like Champ Ocean Instant Heater is a popular choice among HDB owners due to their compact and small design.

Storage heaters are bulky and not very pleasant to the eye, so homeowners would usually want to conceal the storage heater. Some are fitted above the false ceiling for condo homeowners, others, above the roof for landed property owners, or even exposed wall-mounted for HDB owners.

Water Pressure and Temperature Consistency

Ever experience an unpleasant shower due to lower water pressure for the shower head? If you ever serve National Service, you most definitely did. Those were the days when you have to press the knobs a few times to fully complete your shower.

Water pressure greatly determines the shower experience, more so than people usually think.

Instant water heaters are often associated with restricted water pressure. Most instant waters have in-built restrictors so as to enable instantaneous heating of the water flowing through the pipes. This ensures that the temperature of the water can reach up to 39°C.

Water pressure and temperature consistency for water heaters are interlinked.

For instant water heaters, when there is another usage from another area coming from the same water supply, the inlet of water will decrease, causing the water pressure to drop, during which the temperature will increase at the output which leads to inconsistent temperature.

However, due to advancement in technology, companies such as Ariston has come up with innovative instant heaters to combat such issues. One such example is the Ariston SMC33 Instant Heater.



With the innovative new technology, Ariston SMC33 Instant Heater will provide you with the consistent temperature and water pressure of your desires.

Storage heaters, on the other hand, provide consistent water pressure and temperature due to the nature of their structure, in which water is pre-heated in the tank before use and dispensed during usage. The only limit it has would be its capacity.


The cool and sleek Ariston Andris SL20 provides you with consistent water temperature as well as excellent water pressure to ensure a pleasant showering experience.

Energy consumption

With the advancement of technology and innovation, consumers are more environmentally conscious when it comes to products that will affect their surroundings. Everyone has a part to play in creating a clean and green world.

As such, energy consumption is an important factor. Instant water heaters consume less energy than compared to storage water heaters. This is because instant water heaters only heat up the water when it passes through the pipe. The storage water heater uses more energy because the water is stored in a tank, and due to its large capacity in nature, it will use up more energy to heat up the water within.

As mentioned, with the advancement of technology and innovation, water heaters have also come a long way in saving energy. Examples are the Ariston AN30 and Joven JH25L.



The new and innovative Ariston AN30 comes with energy savings performance for the extra savings on your utility bills.


Storage heaters like Joven JH25L help to save energy consumption by up to 20%!

Life Cycles & Maintenance

When purchasing a water heater, you will wonder how long can this water heater lasts? When do I need to have it checked again?

Based on the information provided by our suppliers, manufacturers, customers, and our expertise, the average life span of an instant heater is estimated to be around 10 to 15 years. It is recommended to get the wiring checked every 3 to 5 years.

The average life span for storage water heaters is around 8 to 13 years estimated. It is recommended to do a water tank flushing every 5 years to prolong the life expectancy of the storage water heater.


The all-important after-sales guarantee for your water heater. Never get your water heater from some dubious salesperson.

Different brands have different warranty periods based on their manufacturer. Not forgetting the warranty period for instant water heater and storage water heater also differs from each other. Generally, the storage water heater has a warranty period for its parts of around 3 to 10 years depending on the brand. Whereas an instant water heater usually comes with a 1-year warranty.
