Differences between instant and storage water heaters
Which geyser has the highest capacity range?
Capacity, in general, is the amount of water a geyser can hold. With every manufacturer and every model of a geyser, its capacity differs. Capacity is the most important factor which separates instant geysers and storage geysers miles apart.
While an average instant geyser can hold about 6 liters of water, most storage geysers come with 20-50 liters of capacity. However, with higher capacity, the heating time suffers remarkably. That’s exactly why an average instant geyser can heat water way faster than any storage geyser of the lowest capacity.
Winner: Storage Geyser
Storage or Instant water heater – which one takes less space?
The size of a geyser determines how much space the appliance will take if you install it. And, With higher capacities come larger sizes and vice versa, making storage geysers way larger in size and instant geysers relatively smaller. The size of a geyser also determines its usability.
For example, instant geysers are ideal for domestic uses, especially in smaller bathrooms with fewer people living in them due to their smaller size. On the other hand, the large size of a storage geyser allows it to hold more water, and that’s where storage geysers excel remarkably.
Winner: Instant Geyser
Instant vs Storage Geyser : Power Consumption
The power consumption or wattage of a geyser is the amount of energy it consumes per hour. For example, the wattage of an average instant geyser is rated at around 3-4 kW. At the same time, storage geysers are available with 2-4 kW. To understand it clearly, let us consider two examples-
1. Bajaj Flora Instant 3 Litre Vertical Water Heater
The rated power of this geyser is 3000 watts or 3 kW. If it runs for one hour with 100% efficiency on a chilly winter day, it will consume 3 kWh of power. With an electricity tariff of Rs. 8/unit, it will cost you Rs 24.
2. Bajaj New Shakti Storage 15 Litre Vertical Water Heater
This storage geyser has a rated power of 2 kW that costs only Rs. 16 for running an hour under similar conditions to the previous Bajaj Flora Instant 3 Litre Vertical Water Heater.
Though power consumption of geysers depends on a few other factors like ambient temperature, the volume of water to be heated, we can say that storage geysers are better.
This significant difference in wattages of instant geysers and storage geysers impacts the real-world power consumption of the geysers and their operating costs. It’s highly recommended to purchase a geyser with a high BEE rating in either case.
Winner: Storage Geyser
Which water geyser heats up faster?
Both instant and storage geysers operate differently and thus take different times to heat the water. An instant water heater (geyser) heats the water in its heating chamber almost instantaneously, thanks to the huge wattage of the geyser.
Meanwhile, storage geysers heat a large volume of water in one go which takes time. As the technology advances, the heating time of storage geysers is slowly but steadily reducing.
Still, with its current level, a storage geyser of average capacity can take 15-20 minutes to heat a single load of water. An instant water heater, in contrast, takes mere seconds or minutes to do the job.
Winner: Instant Geyser
Instant or storage water heater – Which is more durable?
You can determine the durability of a geyser simply by observing how well it retains its performance despite heavy and rough usage. Both types of geysers (storage and instant) involve different components and use different approaches towards heating water.
As a result, storage geysers and instant geysers do not share the same durability. Thanks to the advanced mechanism and better-quality components, instant geysers are far more durable than storage geysers.
Winner: Instant Geyser
Which geyser is easier to use?
You can refer to it as the convenience of using the geyser. For example, instant water heaters require you to do nothing, turn the tap on, and you’re good to go, no additional steps to heat the water.
At the same time, storage geysers function differently and demand a proper setup to work ideally. Storage geysers also take around 30-60 minutes to heat the water in the tank. Instant geysers shine when it comes to ease of use.
Winner: Instant Geyser
Storage vs. Instant geyser : Price
Since instant and storage geysers do not share the same specs or operation, they are priced differently with comparable capacity. Storage geysers particularly excel in the pricing department as they involve less advanced components. Their installation cost is also far lower than that of an instant geyser.
Meanwhile, buying and installing a high-capacity instant geyser can be a bit expensive. For example, while a 3-liter instant geyser can cost you around Rs 3000, a 10-liter storage geyser usually costs less than Rs 6000. This is very affordable considering the water-holding capacity.
Winner: Instant Geyser
Maintenance of instant geyser and storage geyser
Recurring costs include the overall maintenance cost and electricity cost that a geyser demands throughout its life cycle. In that case, the quick action of instant geysers comes into play. Since instant geysers fairly live up to their title by heating the water almost instantaneously, although they have high wattage, they consume less power per usage.
In addition, instant geysers demand less maintenance and care, which contributes to their low recurring cost. Also, storage geysers can undergo frequent maintenance and are less power-efficient in the long run, unlike instant geysers. The recurring cost of storage geysers gets relatively higher in the long run than the recurring cost of instant geysers.
Winner: Instant Geyser
Which geyser has more lifespan?
Count the years of reliable service from a machine, and you’ll get its lifespan. Factors including the quality of mechanical components and the maintenance frequency are primarily responsible for deciding the lifespan of a geyser.
The average lifespan of an instant geyser can be between 12-15 years which you can stretch up to 2 decades with good maintenance. In contrast, storage geysers have a typical life expectancy of about 8-12 years only.
Winner: Instant Geyser
Best Uses of Instant and Storage Geysers
The best use of either type of geyser is a function of one’s needs and requirements. However, instant geysers are ideal for domestic use due to their small size and higher cost-efficiency in the long run when it comes to general usage.
However, since they can only supply a fairly limited amount of water in one go, you can expect frequent breaks in the flow if you use them extensively. So, that’s where storage geysers come into the picture. Since these geysers can hold a chunk of heated water in the storage tank, you can expect a seamless experience from storage geysers.
So, Which is better – instant or storage geyser?
A geyser or water heater as an appliance needs no introduction. In various homes in India, you will find geysers fixed in the bathrooms or the kitchens. Apart from conventional electric geysers, gas geysers are also available in the market.
To conclude this debate of instant water heater vs storage water heater, it would be reasonable to say that the best one varies for different requirements. Both these water heaters are unique and have been crafted using different designs and mechanisms. Their prices also depend on these functionalities.
Hence, as a user, you need to analyze your requirements and figure out which will be the ideal geyser for you. In terms of power consumption, storage geysers are better as they have lower electricity ratings. Storage water geysers are ideal for a large family. On the other hand, get an instant water heater if you are a couple or have a small family with kids.
