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 differ. Brands such as Ariston are generally more expensive than compared to brands such as champs.

Instant water heaters are also generally cheaper than compared to storage water heaters.


  1. Installation

Instant heaters are small and compact; thus, it does not use up much space than compare to storage heaters.

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 where 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 thinks.

Instant water heaters are often associated with restricted water pressure. Most instant water 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 came 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 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 its 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.

  1. Energy consumption

With the advancement of technology and innovation, consumers are more environmental 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. 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 advancement of technology and innovation, water heaters have also come a long way in saving energy. Examples are the Ariston AN30 and Joven JH25L.
