Instant Geyser vs Storage Geyser/ Water Heaters

When anyone wants to purchase the geyser or water heater, he has a fundamental confusion about which type of geyser is suitable for either Instant geyser or a storage geyser.

To answer this question, here is a difference between instant geyser vs storage geyser/water heater in different parameters.

And after the comparison, I will recommend some great water heaters that are available in the market.

Instant Geyser vs storage geyser

Instant Geyser vs Storage Geyser/ Water Heaters

1. Capacity available in the market:

Instant: Instant geyser comes with mainly three sizes 1 liter, 3 liters, 6 liters.

Storage: Storage geyser comes with various capacities like 5 liters, 10 liters, 15 liters, 25 liters, etc.


2. Purpose:

Instant: Instant geyser mainly used in the kitchen. You can use it in your bathroom if you have a small family of upto five members.

For 4 to 5 members, you must go for a 6 liters capacity instant geyser.

For 2 to 3 members, the 3 liters capacity instant geyser will be sufficient. And 1-liter capacity geyser mainly used in the kitchen.

Storage: Storage geysers are used in bathrooms. And if you have a large family (7 to 8 members), you must go for a 15 to 25 liters storage water heater.


3. The time required for heating:

Instant: As the name suggested, the instant geyser takes few seconds (almost instantly) to heat the water. 

If you have a hectic schedule in your day to day life, then instant geyser is ideal for you.

Storage: Storage geyser takes atleast 4 to 5 minutes to heat the water, and the waiting time increases if you have higher storage capacities.


4. Space consumption:

Instant: It requires a small space. So, if you don’t have ample space in your kitchen or bathroom, you can install an instant geyser.

Storage: It requires ample space due to the storage tank. So, make sure that you have adequate space in your bathroom area.


5. Lifespan:

Instant: The lifespan of the instant water heater is high comparatively due to the absence of a storage tank.

Storage: The lifespan is less comparatively instant type.


6. Energy efficiency:

Instant: Instant water heaters are more energy-efficient, and it can save upto 20% to 30% energy.

Storage: Storage geysers are less energy-efficient, and they consume more electricity than an instant geyser.


7. Price:

To compare the price, we must take one constant parameter.

In this case, I am assuming the storage capacity is constant.

Let suppose we have two water heaters first is instant, and second is storage, and both have the same capacity of 6 liters.

Then the cost of instant geyser will be high as compared to storage geyser.


Summarizing into table


Time requiredFew seconds4 to 5 minutes

What should you buy?

If you have a large family (7 to 8 members), then you must go for a storage geyser.

And if you have a small family, you can go for either instant geyser or storage geyser of low capacity.

I recommend you instant type because it is energy efficient (saves electricity bill), less time required, and long lifespan.

Here is an approximate table. It will help you to buy the suitable model
