This way you can make a decision depending on what your requirements might be. If you are wondering about the different type of geyser that you can find in the market, we suggest you start with what you are looking for exactly.

Type of Geyser – Different Types of Water Heaters

Geysers or water heaters are some of the best, most convenient appliances to have in your home. If you are someone who lives in the more colder regions, or if your region has harsh winters, a geyser is literally one of the most crucial appliance to have. Not just for baths, geysers are highly multifunctional and can provide you hot water for a variety of purposes. You can just as well install one in your kitchen without worrying too much about it.

That said, buying a geyser is not easy. Yes you can always go into a store and buy any commonly found storage geyser, but what if you could do better? And yes, you can do better. While we understand that storage water heaters are really convenient, easy to use, long lasting, and don’t cost a lot either, the other type of geyser you can find in the market might function better when they are put against your usage and requirements.

Before purchasing a geyser, you need to understand the different kinds of geysers available and how they go about heating the water for you. Geysers all work for the same purpose, to heat up water for use. However, how they get that done varies from geyser type to even specific models.

Let us take a look at the different geyser types available in the market, separated according to their function and build style.

Type of Geyser – On the Basis of Heating Format

So, when it comes to how a geyser can heat the water for use, there are three primary types of geysers.

  1. Electric Geysers
  2. Gas Geysers
  3. Solar Geysers

1. Electric Geyser

Electric geysers are the most common form of water heaters that you can find in the market. They are found in either of two major types – storage geysers and instant geysers. They use electricity to heat the water and are widely available in the market. Depending on your use, you can easily get something that best suits your requirements since they tend to be available in several models ranging in different capacities.

Electric geysers are easy to use and maintain, therefore the wide use. They also do not cost a lot, and are rather safe to use as well.

The two different variations they are available in, instant geysers and storage geysers, perform the same task, but their methods are different. Storage geysers come with a tank to store and heat water, while instant geysers provide heated water instantaneously without any waiting required.

Electric geysers prove some of the top 10 best water heaters in India.

Advantages of Electric Geysers

  • Storage availability means heated water can be stored for longer
  • Instant electric geysers are perfect for use in a kitchen situation
  • Much easier to find in the market
  • Tons of options available
  • Easy to install and use
  • Easy maintenance
  • Ability to customize the temperature of the water

Disadvantages of Electric Geysers

  • Operating costs and utility bills can see an increase

2. Gas Geyser

Gas geysers are slightly different than electric ones. They perform the same task, but instead of using electricity, most of the heating is done through gas, and their function is also instant in nature.

Gas geysers require an LPG connection to function. You can either send piped gas to it, which means you do not have to be refilling it since its connected to a gas line, or you can use cylinders of LPG to heat the water and change them out once the gas has run out.

Most people do not get gas geysers due to two reasons. First, their safety issues. Yes, gas geysers can be quite difficult to work with and the potential damage it can do is also pretty high. But the thing is, gas geysers are built incredibly durable and safe to use. There are multiple precautions, and by only following a few useful steps, you can make sure your gas geysers runs for years on end without any issue. The second reason why people do not get a gas geyser is the delusion of increased operating costs. If you think that running a gas geyser is more expensive than electric geysers, you are terribly wrong.

Gas geysers are quite effective at their job, and their instant approach means you do not waste any valuable gas heating your water. If you are building a new house for instance, installing a gas geyser for the entire household could be a great idea. That said, finding a good gas geyser, getting it installed, and maintaining it over the years it will be in use will be quite the chore. So do keep that in mind.

Advantages of Gas Geysers

  • Durable and more long lasting than standard geysers
  • On demand hot water
  • Lower utility costs in the long run
  • Does not take a lot of space, can be installed elsewhere as well
  • More efficient at heating water

3. Solar Geysers

Now, here is something that is a win-win situation for everyone involved. Solar geysers are some of the best appliances you can install in your home. If you live in a place that gets ample sunlight, keeping a couple, maybe even a few solar geysers up on the roof can take care of all of your heated water needs as easily as it can be.

Solar geysers, as the name suggests, use the sun’s energy to heat the water. The sunlight is converted into electricity which slowly heats the water in the connected storage tank for you to use. So as long as your geyser gets sunlight, you will have heated water at all times. This costs you no extra money, and so basically you would save a ton of money if you use a solar geyser to heat up your water.

There are only a few drawbacks however. Since you need sunlight in the first place, overcast weathers will only render your geyser useless. Another problem is that the geyser is slow to function. To heat an amount of water, it generally takes twice, even thrice as long as a normal electric water heater would. However, the storage option is great to keep the water heated inside, and use it whenever you have to.

Advantages of Gas Geysers

  • Relatively quick function, takes only 15-20 mins to heat water on a good sunlit day
  • Can store a lot of water for use
  • Does not consume or cost electricity at all
  • Great for the environment as well
  • High durability

Disadvantages of Gas Geysers

  • High purchasing cost

  • Heating is difficult on cloudy days
  • Overheating is common since most models do not come with a thermostat to control the temperature
  • Needs more maintenance since they are generally installed outside

๐Ÿ“Œ Besides the different types of geysers mentioned in this article, immersion rods can also be used to heat water. These are inserted into the water and heated using an external power source, such as electricity. The advantage of using the best immersion rod is that it can be used to heat water very quickly. However, the disadvantage is that it can be dangerous if not used properly.

They hold a certain amount of water, depending on the size and model you have chosen, and heats the stored water whenever you switch them on. Once you have used all the stored heated water, you will have to start the cycle of filling the tank with water and heating it.
