Things To Consider While Buying Water Heaters In India

Let’s look at the factors which needs consideration before buying the best quality instant water heaters.

Impact of family size:

Water heater size is an important factor while deciding which geyser will be the best for your family’s needs.

  • If there are two to three members in the family and the purpose is bathing, then, the instant geyser of 6 liters would be the right choice.
  • If the same family uses a storage geyser, it would require a capacity of 10 to 15 liters.
  • While if the family bathes using the shower, the storage water heater must be 25 liters.
  • If there are more members10 baking with the bucket will also require a 25-liter storage tank.
  • If the purpose is washing utensils, an instant water heater of 1 to 3 liters of capacity will do the job.

Power Consumption:

You must keep in mind the power consumption and wattage of a water heater, which determines whether your best water heater is slow or fast. Water is heated quickly in a 4.5-kilowatt instant geyser which is unlikely in the 2-kilowatt water heater. The water heaters with more wattage also tend to save electricity, and they can put a stop to the wastage of hot water.

Water Heater Elements

  1. Heating Coil
    • The heating element of the best water heater is very important in determining whether the geyser is good or not. The insides of the stands are usually lined with glass which prolongs its life and prevents scaling.
  2. Water Tank
    • The tank that holds the water must be corrosion-resistant and very durable. In these years vitreous enamel glass coat has replaced the stainless steel tanks. These geysers are coated with advanced polymers and avoid scaling by hard water. They also give 5 to 7 years of warranty and are almost the same as a glass-lined coating.
  3. Thermostat
    • The thermostat is another important part of the instant hot water system, which takes care that the water doesn’t overheat. Its work is to decide when to start and when to stop the appliance. It contains a bimetallic strip made up of steel and copper. The thermostat is wrapped around this strip which does its work according to the response of the strip.

Most of the time thermostat temperature ranges from 30 degrees Celsius to 60 degrees Celsius. Due to heat loss, even if you forget to turn off the heater, it will cool down the temperature to normal. It would continue with this loop until you switch it off, thus saving the blasting and overheating. However, one should be very alert and remember to switch the best water heater off as soon as its need is fulfilled.

Types of Water Heaters

There are mainly two types of water heaters that are gas geysers and electric water heaters. We would strictly recommend you to use only branded electric geysers and not gas ones.

Branded electric water heaters will provide you the safety, guarantee, and good customer service. While an unbranded geyser would look more cost-effective, but it could be dangerous, and avoid not buying those that take up extra power.

You would want to look for an ISI mark on the best water heater to ensure low maintenance costs, as laid down in India. A gas geyser takes more time to heat water than the instant electric water heaters.

Electric Water Heaters

There are two types of best electric water heaters, that is, instant water heaters and storage water heaters. The instant one takes up less space and provides the hot water immediately while the storage one takes up more space, and you need to wait for a few minutes before the water heats up.

Comparing the cost of both the water heaters instant water heaters are a bit costlier than storage heaters. The instant water heater is available in 1, 3, 6, and 10 liters capacity while the storage geysers’ capacity range from 6 to 35 liters.

The lifespan of the former is considered higher than the latter and is best for washing utensils, hand washing while people prefer the latter one for bathing with a shower.

Other Types

There are various types of water heaters for various purposes. Geysers are available for hard water, high-rise buildings, and kitchen purposes. A geyser meant for high rise building must have more than 6 bars and a control valve to release the pressure water and avoid the breaking of the tank, for hard water one must choose a geyser with high corrosion resistance because otherwise, it could damage the water heating element.

  • Horizontal geysers are new in the market, unlike the vertical ones we have always seen. They free up the space of the bathroom wall and helps when there is an attic or a low ceiling.
  • Solar water heaters are really helpful when it comes to saving your electricity bills and preserving the environment. They might require high investment in the beginning, but they will prove worthy of it in the long term. These are the best water heaters for big apartments.

Smart water heaters

Smart water heaters are our also thing these days as they allow you to control using your mobile phones. You can simply plug in the smart plugs and set the time at which you want the heater to start and stop. With this, you don’t have to worry about getting late to work, and you can get water as soon as you wake up.

Water Heater Installation:

Best Water heaters must be carefully installed by an authorized serviceman. Avoid calling a local plumber as they won’t look into the safety guidelines. He would charge you more than the service center without doing the work properly. They do not acquire the knowledge and may remove important parts considering them useless. You may later face problems of leakage.

One can easily solve all water heater problems themselves without having to contact any serviceman. Most of the troubleshooting problems that arise in the water heaters are due to the wrong installation.

In this article, we have also shortlisted some of the common problems that you may face while installing. The wall mounting space should be well checked before the process. A space of at least 2 feet is needed to install a vertical geyser. Otherwise, you can opt for a horizontal geyser. 

One must also ensure that all the water pipes are clear of any obstruction or clogging. Check the water connections carefully. You may also need to buy a pressure pump separately if you encounter a low water pressure.

Installing, make sure you have the required equipment. These are two steel ribbed pipes, one valve brass, a connection point, a 15 A plug, tape, bolts, washers, and screws. One must be extra careful while installing a gas geyser as it could be very dangerous or even blast.

How to reduce your electricity bills:

A well-rated best water heater can end up lowering your electricity bills, so we advise you to get the one with the maximum ratings. There are many reasons why electricity and power are lost through water heaters.

  • There are standing losses due to which heat is lost from the surface of the water heaters.
  • The other factor is the amount of hot water used. Obviously, the more water the individual uses, the more will be the electricity consumption.
  • Setting the temperature of the thermostat can help in electricity consumption as they are defaults set at 60 degrees Celsius, but they allow you to modify this setting externally.
  • The temperature of the water which is used for bathing should also be kept in mind as it is different from the temperature of the thermostat.
  • The surroundings around you can have also had a significant impact in colder countries. The heater will have to do more work to heat water and thus, more energy and power consumption.

Final Words

Our recommendation would be to buy Crompton IWH03PC1(3KW) Solarium DLX IWH03PC1 3-Litre Instant Water Heater because it is the best value for money product.

It is so relieving to shower with hot water after the weariness of the day, and this is when these water heaters come handy. Electric water heaters are the best types. You just need to find the one matching your needs and follow the points mentioned above to enjoy hot water in those chilly winters. 

The above-mentioned models are not only highly-rated but also budget-friendly. Maintenance is required after some time, and we advise you to keep children away from its operation. This article would have surely helped you with all the factors you need to check while buying the best instant water heaters.
