How does a Water Storage Tank work?

Water Storage Tanks, as suggested by its name, works by storing cold water in the tank, until it is activated by the heater to heat up the water inside to a stipulated temperature. Most home water storage heaters are able to hold up to 25L of cold water. The heating procedures works similarly to how instant water heater works- a heating element is attached to the storage tank, which is usually made of metallic material such as titanium. Once the heater is activated, it will heat up the heating element via electric heating, hence transferring the heat to the cold water as well.

This video below will explain to you in detail about how a storage heater works, so feel free to check it out!
(Forward to 1:40!)


For Champs Storage Tank, the water will be heated up up to 75 degree. after which, the heating element will automatically be cut off to prevent overheating of the water and allow the water to cool.Once the water cools to 20 degrees, the heating element will be reactivated (as long as your heater is still switched on) and the entire heating process will repeat itself.

Champs produce both Vertical and Horizontal Storage Tanks, but Estore Singapore will be featuring their horizontal tanks in this blogpost!

Storage VS Instant Heater 

Now, you might be curious to know- what are the differences between the water storage heater and the instant water heater?

Firstly, it is obvious that in order to store that much of water, the storage tank will hold up a much larger space than the instant water heater. Hence, most household will choose to purchase a huge water storage heater only if their house is large enough, or if they are want to connect the single storage tank to many different bathrooms or water points of the house.

Apart from the size, a household having a storage water tank will require 2 taps in the shower and all water points to control the cold and hot water output individually. This is so as water coming out of the  storage water heater outlet would be too hot for the human skin. Hence, another tap that controls the cold water would be required to bring the hot water to a suitable temperature. While some may think that this is a troublesome process, others prefer this method as they will have full control over the temperature of the water, as opposed to the instant heater which only has a range of specific temperature to choose from.

Lastly, it is obvious that hot water from the storage tank will deplete when we are bathing, allowing the cold water to enter the storage tank in order to be heated up again. As time is needed for the water to reheat, one will realised that the water will slowly turn less hot if she were to , cold water will then enter into the storage tank. Because it will take time for the water to reheat, one will realise the water turning not as hot as before if she were to take a really long shower. However, don't be too worry about this- unless you are the 7th consecutive person entering the bathing room to shower, you will probably not face this problem!
