The Two Main Types of Water Geysers – Instant, and Storage

It is important to address instant and storage geysers play a crucial role in your decision of choosing a water heater as they both works differently.

As the names suggest, instant geysers heat up water instantly as the water runs through it, whereas storage geysers keep larger amounts of water stored in a heated compartment.

Instant geysers provide hot water as soon as you turn them on. They are significantly smaller and will take up less space in the bathroom. Storage geysers, on the other hand, have a slight delay in providing hot water. For instance, you might have to wait five to ten minutes for the water to heat up before you can use it.

The heating time depends on the size and quality of the geyser. Also, keep in mind that storage geysers are a lot bulkier and will take up more space on the wall.

Instant electric geysers are more efficient in terms of not wasting any hot water and using less energy to heat it up. However, storage geysers allow you to use a stream of hot water for a long period of time without interruptions.

With that said, here are the main differences between these two types of water geysers.

Instant Geyser vs Storage Geyser: The Main Differences

Some of the obvious differences between instant geyser vs storage geyser units are their way of working, size, heating, and time. However, there are even more differences, that are well worth considering. So, we are now going to dive into more detailed differences below:

Time for Heating

Instant water geysers, as the name suggests, provide hot water as soon as you turn it on and just wait for 1 or 2 minutes. This is a perfect solution for people who want to have a source of hot water readily available whenever they need it.

Storage geysers, on the other hand, require a heads up before you start using the hot water. You will need to turn the geyser around ten minutes before use or even longer depending on the type of unit and capacity.

In other words, storage geysers take a longer time to heat up water compared to instant ones but storage ones gives a large amount of hot water compared to instant ones in a single go.

Also, the temperature of water can act on the time required for heating.

Suited for Individual or Family

Instant geysers are not the best option for those who prefer long baths because they can usually release 3 liters of hot water before needing a break, or some liters more depending upon the model. If you are taking a long shower, you could potentially end up waiting for the next round of hot water from your instant geyser.

Once the capacity of instant water is finished, you need to wait a minute or so. If not, the water comes with a lesser temperature ending up in an unpleasant experience.

With a storage electric geyser, on the other hand, you will have a continuous stream of hot water available, which also depends on the capacity of the unit.

For large families, large capacity storage geyser is the best option for bathroom use, whereas average-sized instant geysers are good enough for smaller families or ones who don’t need much hot water for bathing.

Capacity

With instant electric geysers, there is no such thing as capacity as they usually come with a fixed 3 liters capacity. You do not have to worry about running out of hot water because the geyser will heat up the water as it flows into it.

Storage geysers, on the other hand, have a certain water capacity, so you need to choose the storage geysers as per your requirements. Usually, they are available in the capacity of 10, 15, 20, 25 Liters, and some times smaller or larger than the ones mentioned above.

Keep in mind that the higher capacity you choose for a storage geyser, the more space it is going to take, and maybe a notable point in case if you want to fix it in a small bathroom.

Temperature Settings

Both instant and storage water geysers offer a certain level of water temperature adjustment depending upon the model. However, the temperature settings and their quality will depend on the specific unit and manufacturer.

Some of the more expensive geysers will allow you to set specific water temperatures upfront, regardless if they are storage or tankless geysers. Usually storage electric geysers have a much higher temperature range to choose from.

Pressure Resistance

If you live in a high rise apartment, the pressure resistance of a geyser plays a very important role, as the pressure of water inflow is very high especially for those who live on lower floors.

As a result of high pressure, by the time the storage tank may become weak and result in leakage, so it is very important to get a geyser that can withstand high pressures.

In this case, most of the storage water heaters in the market come with an 8 bar pressure resistance or even more, and in instant geysers it will be around 6 or 6.5 and sometimes more. However, the ability to withstand the pressure also depends upon the model you are selecting, the coating material, etc.

So, try to select the geyser that can withstand high pressures, especially if you live in high rise apartments or in the lower floors.

Power Consumption

The difference in instant geyser vs storage geysers power consumption is a very important factor while making a purchase because all of us have concerns about the electricity bills and always in a doubt like which one consumes more power.

Both these water heaters usually consume more or less the same amount of power. Its because finally you are getting the same bucket of hot water and in case the temperature settings are the same.

But instant ones are comparatively little less power consuming because the water is just released out upon heating. While in storage geysers, the temperatures are needed to be maintained until the water is utilized.

The longer you keep the water stored in the storage geyser, the more energy it is going to consume to keep it hot.

Space Required

Storage geysers require more wall-mounting space compared to instant geysers because of the large storage compartment. The higher the water capacity you choose, the more space you are going to need.

That is why instant geysers are recommended as a more space-efficient option if you have small bathrooms.

Also, you can choose a storage geyser with smaller capacity in such case but keep in mind that you will be running out of hot water more frequently and wait until the green switch to on while bathing.

Lifespan and Warranty

When it comes to the lifespan, instant geyser units are expected to last longer than storage ones because they do not have a complex water tank system.

Several factors act on the lifespan of a geyser like the type of water – hard or soft, frequency of use, etc. In terms of years, storage water heater lasts on average about 8 to 12 years and instant water heaters for about 10- 15 years.

But, ensure to get choose a geyser with a good warranty period which helps incase if the geyser runs into a problem.

Price Differences Between Instant Geyser vs Storage Geyser

Storage geysers are generally more expensive than instant ones because of their capacity and heating power. However, the exact price will depend on the capacity of the geyser, as well as the features and brand behind the product.

Although Storage geysers have a higher initial cost, It is also important to keep in mind that Storage geysers are a much convenient option if you have a large family as well as to use for laundry or other household purposes.

Supply of Water for Other Uses 

Instant geysers might not be the best option for showers and also especially for larger families. These geysers have a certain limitation of how much hot water they can provide before taking a break.

Storage geysers, on the other hand, are the best option for bathing, doing large amounts of laundry or even for kitchen use, etc.

Maintenance & Repair

Lastly, instant water geysers require more maintenance compared to storage geysers which is another considerable point.

Storage tanks on the other hand don’t need maintenance as instant ones. However, they can get into problems like scale build-up, corrosion, etc. to deal with.
