Instant Geyser vs Storage Geyser: Which is Better for You?

It is challenging to decide which geyser is better. Instant geysers are the perfect solution for people who want hot water on demand, but storage geysers are suitable for areas that don’t get a regular power supply. Instant Geyser vs Storage Geyser comparison will help you choose the right option for your home.

A geyser is a necessary house appliance for heating water. These days, if you go to the marketplace or even look online, there are so many options that it can be hard deciding what kind of Geysers we want- Instant or Storage type?

Broadly speaking, two main kinds exist, the first being “instant”, where hot water will come out as soon as its filtration system has been activated.

At the same time, storage types take longer periods before generating enough heat but offer steady output throughout their operation cycle until all stored energy has run out.

You should consider a number of factors to determine if installing an in-wall hot water heater is right for you. These include the purpose it will serve (e.g., bathing, cooking), your geyser cost and space availability issues with both plumbing fixtures, as well as accessibility for maintenance needs like scheduled replacement services from qualified technicians.

Also, take into account any additional costs associated with electricity or propane that may come up during the installation process.

Working of Instant Geyser

An instant Geyser is basically a heating device that provides hot water on demand.

Water heaters consume energy (usually electricity or combustible natural gas) and transform it into hot water. It then conveys the heat to make it suitable for bathing.

First thing first, you need to make sure your instant geyser has a minimum flow rate of 0 .5 gallons per minute because most work on lower rates as well. Still, models available can operate with less than 2 GPM – these typically have very little demand, so they’re great if space is not too tight near an outlet where you want one installed.

When you switch on a hot water faucet, cold water enters the tankless geyser through an intake pipe after it detects the adequate flow of this natural resource (heating unit), which is activated by a sensor and quick heating process that warms up all sections quickly, so they never stop operating.

The heated output goes directly to your sink or tub – no waiting around for pipes nor cartridges; just dependable water at hand when needed most without waste from overcooling down again during standby mode due to low volume circulation needs as many other traditional plumbing systems would require.


Water is available at all times.

People don’t have enough time in today’s society. Heating water with a storage geyser may be highly inconvenient and consume all of their days.

But with instant ones, you only need to turn on the faucet to get hot cup after cup as long they’re there – no waiting around.

Less Energy Consumption:

Instant geysers are more energy-efficient than their storage counterparts, but they also take less time to heat the water.

Those are looking at saving 24% on daily costs alone in just one year by using an instant geyser instead of a traditional model with 40 gallons per day use.

Take Less Space

Contrary to their bulky storage-type geysers, the instant geyser is modest in proportion hence require comparatively smaller wall mounting space.

They feature a compact design that can easily match with a limited area and enhance your home decor due to their appealing look.


Instant Geysers are very durable. They can last up to 20 years on average with proper care, and gas-powered ones have an extra few year of life too.

Instant geysers types of water heaters typically live 15-20+ years if they’re well taken care of in your home.

Highly Convenient

It’s quick and easy to have hot water when you need it. A storage geyser can take as long as five minutes, so getting an instant Geysers eliminates this problem for many people in the modern world who live busy lives with little time on their hands.


Installation Charges

Instant water heaters are more expensive and time-consuming to install than storage models. The setup charges for an instant unit can also be high if you plan to replace your old one with a new type of these convenient but pricey devices.

A plumber will need much longer when dealing with an installation that includes installing two different types in close proximity from each other or even just doing basic plumbing work such as turning valves near running pipes – which is already difficult enough without having another appliance weighing down our schedules.

Complex Installation

A tankless geyser’s installation procedure isn’t straightforward. You will have to make special kinds of drills and would need accessories for its installation, but if you are switching from storage type into an instant one, then it is more tedious than just installing another regularly stored water heater in your house.

That’s why we recommend getting help from professionals who can add up easily to the total cost. They know what tools should be used properly in order not to break anything or hurt anyone during this transition period at all costs (even though accidents happen sometimes).

High Maintenance

A tankless geyser lasts much longer than traditional ones because it doesn’t need to be serviced as often; however, if you want your water heating system to function at its peak and operate for years without requiring any upkeep or repairs.

Make sure that, at least once a year (or more), professional plumber visits to repair any leaks that may result from an annual leak check-up.

Water Flow Rate Issue

The essential thing to know about water heaters is that they need a specific flow rate. Water geysers can function only when the per minute number reaches at least 0.5 gallons, but many models work with lower flows, such as those over 2 GPM (gallon per minute).

If you want your device’s heater turned on and boiling water ready for tea-time or coffee break time every day, then make sure enough streams are coming out from under its spout.

Temperature Sensitive

Instant water heaters are a great option for tropical and temperate climates, but they might not be enough in cold states.

The instant geyser’s limited temperature range makes it difficult to use in areas with very harsh winters because there will always be some kind of risk no matter how much insulation one has on their home.

When the water is at or below 4 degrees Celsius, it will become difficult for an instant geyser and low flow rate to have trouble working together.

To raise the water temperature to 40 degrees, which is at 15 degrees, this type of geyser will take about 1 minute. And it’ll only require 2 minutes for heating 60 degrees water or more if it’s below 20°C (68 °F).

The heat distribution might not be even when a geyser is connected to the water outlets. The running coldness of one faucet could vary from another because it’s bathing in different sources and receiving less energy than others that have hotter streams coming out of them.

Instant geysers are therefore not suited for large families with many people using multiple appliances simultaneously because they will be continuously heating water to achieve a steady temperature.

Instant Geyser vs Storage Geyser

Working of Storage Geyser

A storage water geyser has an intake through which it receives cold water. With electricity or gas as a heating source, it generates hot water with an outlet that is connected to faucets and showers.

This process takes place inside insulated walls where heat cannot escape since there are no ventilation options other than using energy, leaving them unable to use up all their stored resources before they need another refill from your home’s plumbing system(s).

A quality run time will depend on how long you want amenities such as tea kettle capability without having to turn anything back onto itself again – but if left unused for a longer period of time, it will need to be reheated once more before use.

The capacity of a storage geyser is important because it takes time for the water in your home to heat.

If you have two people, buy one that holds 20-30 gallons; if there are three members total at home or just yourself and another person living on their own, then consider going up to 40-gallon tanks, so they don’t run out during hectic mornings. From 4 plus persons, choose 50 Gallons as needed by all family members.


Less Costly

Storage geysers are the best for storing your water heater. They come in all shapes and sizes, so you can find one that suits your needs without breaking the bank.

Storage heaters with natural gas tend to be more expensive than those running on fuel oil but still affordable if you’re looking at upper-end models like electric storage units or tankless hot-water systems, which cost much less per year as they don’t have any daily operational expenses.”

 Ability to Store Water

With this kind of geyser, your quest for warm water may not always be dependent on the availability of power. This is because they can Store heated and provide a few gallons when facing an outage during the cold season.

Easy Installation

Setting up a storage water burning unit is cheaper and more straightforward than other people. The setup charges for these devices can be less when compared with different appliances, which makes it easier on your pocketbook.

Installing them will never bother you since installation time isn’t complicated at all as some others make the process seem like an intricate, confusing task that doesn’t have any good results insight.

Instant tankless geysers are designed just how you want everything done without having hassle- both during set up or later down the road due to wear & tear over the years using this product regularly.

Repair price.

In the long run, if you need to replace your storage device because of malfunctioning or low-functionality capacity, it won’t be too costly.


Needs More Space

It is important to consider the space that you have available before settling on a storage geyser. Storage units are large and require an expansive amount of room, so it would not be wise for people with limited living space like college dorms or small houses because these water heaters take up too much room in their homes while providing no additional benefits.

High Energy Consumption

Storage geysers are a drain on our energy resources. They take time to warm water, which is repeated with every use since they don’t get hot enough themselves- and this all adds up.


Geysers are awesome, but they have one downside: waiting. If you’re in the middle of doing something and your hot water runs out, then it can be really frustrating because there is no way to reheat more without getting cold again.

It’ll take about 5 minutes for a new geyser cup full enough that provides 30 seconds worth (5-minute wait)


Installing a storage water heater is quick and easy, but they have shorter service lives than instant ones. They also need to be replaced more frequently because as time goes on, minerals are deposited on the heating element that can rust or otherwise damage it over the long term usage of an older model unit from another brand which eventually leads those parts wearing out faster too.

FAQs: Instant Geyser vs Storage Geyser

What is a tankless geyser?

Tankless geysers are called instant water heaters because they can produce hot showers, bathtubs and sinks of ample supply with just one press.
These tanks don’t require time-consuming waiting for the desired temperature to be reached like in traditional storage unit devices such as tanks or boilers, where it may take 30 minutes before you get your fill.

Which geyser is better, instant or storage?

Storage geysers are perfect for those who don’t need hot water all the time because they take a little while to produce, such as when cooking. Instant geysers, on the other hand, are better for those who live in warmer climates and need their hot water all the time or for those that need a lot of hot water at one time.
Instant geysers provide quick and ready-to-go showers and baths without having to wait and waste time and money heating up cold water again.
Instant geysers are more expensive than storage units, however. Instant installations can also be costlier than their counterparts due to the fact that they’re expensive and require venting appropriately for safety purposes while not requiring traditional vents at all.

Does an instant water heater consume more electricity?

An Instant geyser can be a drain on our energy resources. Although both types of water heaters produce hot water, the capacity and delivery time is different.
Instant Heaters can provide between 3-4 kW, which means it draws more power from your electricity supply than a storage unit with a 2kW rating will require (especially if you have just used 15 litres).

What will happen if I forget to switch off my geyser?

In case you have a storage geyser without the feature of auto turn off or standby, it can cause serious damage to both your home and its plumbing. It may burst in some cases if left on for too long with no use at all, triggering issues such as clogging, which would require costly repairs down the line.
But when using instant Geysers, they will go into standby mode just by closing their faucet once more, so there are no worries about being unattended while bathing plus, these types don’t need much water pressure either, making them easier than ever before.

What should I do in case there is an emergency with my water heater?

If your water heater is making strange noises, or you see jolts of fire on the electric board and other situations that may cause hazards to wear plastic slippers. Take a wooden spatula to pull off the plug from the socket if possible, then call an expert for help.

Do not approach any burning wires as this could lead to danger; instead, turn off the main switch in the house before calling emergency services like electricity company etc.

Conclusion: Instant Geyser vs Storage Geyser

Instant water heaters have so many advantages that it’s hard to imagine any disadvantages of the product. They can provide a generous amount of hot water at all times, and they don’t cost much more than conventional units.

This means you get your money worth with these instantaneous boiling systems in no time flat – giving them an easy win as the best value for money choice among homeowners out there today.
