How does the instant water geyser/heater work?

The instant unit contains metallic coils dipped inside the unit’s small stainless steel water tank.

Instant geysers come within the capacity of 1-3 Litres, anything more than that is considered to be a storage water heater.

Just as the name suggests, these units give you hot water instantly as you demand. The process works exactly the way heating rods use to work.

The metallic coil dipped in the tank increases the temperature of the water. 

However, it is very much safe compared to the rods because of the excellent build quality and inbuilt safety.

Now, the water temperature depends on the flow inside the tank. For instance, if you’d like to get the temperature increased, you will have to lower the water flow or increase the coil efficiency.

How & where can you use an instant water geyser?

Instant geyser is always suitable for places where the water is less used, i.e., washbasins, or kitchen sinks. 

So, you need to turn on the instant geyser around 60-70 seconds before you need hot water. Also, continuous water flow is required for using instant units.

Once you turn on the unit, it will show up a sign on display indicating the water is heated and is ready to use.

Whether you get a sign or not, it is always advisable to open up the tap, check the water first, and then use it.

Let’s now discuss the advantages & disadvantages of the unit.

Pros of purchasing an instant water heater geyser:-

The instant units are effortless in productivity. They are very much electricity efficient as they consume less power than a storage unit.

Storage units are slightly heavy and need more space, whereas the instant units are small in dimension and take minimal mounting space.

You get an extended warranty with the instant units. Also, the lifespan of instant geysers is higher as compared to the storage ones.

Be it any of the technology; geysers run on electricity, which is very environment friendly. No harmful gases are released during the heating process.

An instant geyser gives you hot water instantly, which is not the case with storage units. You have to wait for at least 5-10 minutes in storage heaters.

Most importantly, you can even access the instant water heater remotely. Some smart units cut off the power once it determines that the water is heated enough as per requirement.

So, the above were the advantages of buying instant geysers, but every coin has two faces, let’s discuss the disadvantages quickly.

Cons of purchasing an instant water heater geyser:-

As mentioned initially, instant units are best for areas where the requirement of water is very minimal.

Hence, if your purpose of using geysers is in the washroom or you’d like to shower, then storage units are the best because they come with up to 40 Litres.

If you live in an area with hard water, you’ll spend more on the maintenance of an instant unit. Storage geyser requires less upkeep as compared to the instant units.

Initially, you will have to spend extra on instant units as they cost slightly more than the storage units.

Because instant geysers provide hot water instantly, it’s ideal from an individual’s point of view; however, overall, it makes a slight difference.

Since the instant units work instantly, it requires a high power requirement immediately during the process.

The instant units costumes around 3.5 KW- 5.5 KW power whereas the storage units consumes around 2KW

Thus, in the long run, storage units are considered to be more efficient than instant units as an exception.
