How to choose an instant water heater?

When selecting an instant water heater, capacity and power are two of the most important considerations. The capacity of the unit will determine how much hot water is available at any given time, while the power determines how quickly the unit can heat up the water.

  • Capacity: In terms of capacity, it is important to choose a unit that is large enough to meet the hot water needs of your household. If you have a small family, then a 3-litre unit may be sufficient. However, if you have a larger family or if you often entertain guests, then you may need a unit with a capacity of 6 litres or more.
  • Power: As for power, it is important to choose a unit that can heat up the water quickly. A unit with a higher power rating will be able to heat up the water faster, which means that you will not have to wait as long for the hot water to be ready. Most instant water heaters have a wattage of 3000-watts
  • Warranty: When choosing an electric water heater, it is also important to consider the warranty. Many manufacturers offer a warranty on their products, so it is worth checking to see if the unit you are considering has a warranty. This will protect you in the event that something goes wrong with the unit.
  • Safety: Safety features are another important consideration when choosing an electric water heater. Many units now come with features such as overheat protection and anti-scalding protection. These features can help to prevent accidents and injuries, so it is worth checking to see if the unit you are considering has these features.
  • Installation: Finally, it is also important to think about how easy the unit is to install. Some units are very easy to install, while others may require more work. If you are not confident in your ability to install the unit, then it is worth paying someone to do it for you.

By following these tips, you should be able to find an electric water heater that is perfect for your needs. Remember to consider all of the factors listed above before making your final decision.

Why buy an instant water heater?

Water heaters are an essential part of Indian households. They not only provide hot water for bathing and washing but also contribute to the overall efficiency of your home. While storage water heaters are the most common type of water heater in India, instant water heaters are becoming increasingly popular due to their many benefits. Here are a few reasons why you should consider buying an instant water heater for your home.

  • Energy efficiency: Instant water heaters only heat the water when you need it, which makes them much more energy-efficient than storage water heaters. This can help you save money on your electricity bill and do your part to reduce your carbon footprint.
  • Reduced wait time: With an instant water heater, there is no need to wait for the stored hot water to reheat. This means that you can have hot water on demand, whenever you need it.
  • Space-saving design: Instant water heaters are typically smaller than storage water heaters, which makes them perfect for small homes or apartments.
  • Safety features: Many instant water heaters come with safety features such as leak detection and automatic shut-off that can help prevent accidents.
  • Durability: Thanks to their compact design and lack of moving parts, instant water heaters are typically more durable than storage water heaters and have a longer lifespan.
  • Easy installation: Instant water heaters can be easily installed by anyone with basic plumbing knowledge.
  • Reduces hard water scale buildup: Hard water often leaves behind a white mineral scale on surfaces like taps and shower heads. Instant water heaters can help reduce this mineral buildup as they do not store any hard water.
  • Low maintenance: Since there are no storage tanks or heating elements in contact with the water, instant water heaters require very little maintenance.

Tips to know for your instant water heater

  • Consider installing several instant water heaters: If you live in a large house, it is very likely that the water points are quite far from each other. It is therefore necessary to install several instant water heaters, instead of a centralised system. This saves energy and maintains a good flow of water even if several people use hot water in the house.
  • Install your instant water heater near a water point: As you know, the water heats directly in contact with the resistance before being directly available. Also, remember to install your water heater no more than three meters from the water point in the bathroom or kitchen. Otherwise, the water may cool in the pipes and the installation will be useless.
  • Descale your instant water heater: To do this, start by disconnecting the appliance from the water and electricity supply. Then, unscrew the central plate and take out the resistance. Then, immerse it in heated vinegar for a few hours and brush it gently. The tank must also be cleared of limestone sludge. Once the resistance is completely dry, you can put it back into the tank.

Conclusion

The best instant water heater in India is the one that meets your specific needs and budget. There are many factors to consider when choosing an instant water heater, such as the safety features, the capacity, the warranty, and the price.

With so many options on the market, it is important to do your research in order to find the best product for your home. Keep in mind that an instant water heater is a significant investment, so you want to make sure that you choose a model that will provide you with years of reliable service.

Frequently Asked Questions about Water Heaters (FAQs):

1. What is an Instant Water Heater?

An instant water heater lets water pass through its heating element, providing almost instantaneous running hot water. Since an instant water heater has no need for water storage, it takes a lot less space than its counterpart – the conventional water heater. They work on electricity and on gas as well – providing a continuous flow of water.

2. Which water heater is best storage or instant?

Depending on use and availability, either are not that far from each other. The instant water heater has a higher upfront cost – purchase and installation, but also is way more energy efficient than the storage water heater. Smaller families or a couple of people can use a basic instant water heater. The instant water heater saves time – since the storage kind takes time to heat the water. To know more, read this article on storage geyser vs instant geyser.

3. How does an instant water heater work?

A heating element constantly heats flowing water inside the appliance. Unlike the traditional geyser, which stores the water and slowly heats it. Being instantaneous in its approach, the instant water heater is more sought after. Hot water flows out the output valve as soon as the input valve is switched on. Therefore, there is no delay in the output of hot water.

4. Does instant water heater consume more electricity?

It is far more complicated than that. If you were to heat the same amount of water in both the appliances – the instant water heater will put load onto the system. Essentially there will be a sudden need of electricity because of how the appliance works – it heats up the water instantly which requires more energy. In our article on electricity consumption of geyser, we’ve shown exactly how the consumption is calculated.

5. Can I use instant water heater for shower?

Yes, you can use an instant water heater for showering. However, you may want to consider a tankless water heater if you have a large family or high water usage needs, as they will provide a more constant flow of hot water. Instant water heaters are great for small families or those who only need hot water occasionally.
