Buying Guide for instant Water Heater
As water heaters in India are available in different capacities and wattages, you might wonder how to choose a suitable one for your requirements. However, selecting the best instant geyser for your bathroom or kitchen is easy if you consider the crucial decision-making factors. So, let us have a look-
Capacity and family size
An instant heater serves hot water to an entire family. The heater’s capacity should be 1-3 litres for a bachelor or a two-member family.
It should be 3-6 litres for a small family of around 2-4 members. At other times, for a large family of approximately five members, it must serve 6-15 Litres. Geysers with more than this capacity is suitable for bathtubs too.
For example, Crompton Bliss 3 L Instant Water Heater has enough to help a couple or a small family of 3-4 members. Such a capacity is suitable for washing dishes in your kitchen and bathing.
To understand water heater’s capacity, you must consider-
- Flow rate: For tankless water heaters, the flow rate depends upon the size. Calculate the average amount of water you would require. Then match the figure with the flow rate per minute. It will give you a clear idea about the capacity of a heater.
- First-hour rating (FHR): FHR refers to the amount of hot water a heater generates during the first hour when it is highly heated. The higher the FHR, the instant geyser is brilliant.
space requirement by instant geysers
There are various types of water heaters in India with different sizes. So, how should you determine which one suits your household best?
Firstly, determine the area where you will place the heater. Then select a product with at least smaller or equal to that size. In this way, the entire water heater will fit perfectly. However, you must also check the position of water distribution point. Also, consider the distance from plug point and length of the cable.
For a solar water heater, you must check the collector area, storage volume, etc. These are primary measurements that such a heater requires.
Storage geysers and gas geysers have different sizes. A medium to large tank size of 6-20 L serves all families. A compact instant geyser eats up the least amount of space.
Energy/ Fuel Source of instant water heaters
There are various forms of water heaters depending upon the fuel. These are the common types of heaters-
- Electric water heater: This type of geysers use electricity as their fuel, so they have large cables as we know that an electric appliance means higher electricity bills. So, these appliances are not energy efficient. But they work well when it comes to faster heating. They are comparatively cheaper than others.
- Gas water heater: Two types of gas geysers-one uses natural gas as its fuel. On the other hand, there is a propane water heater. Natural gas heaters are more energy-efficient as they are much more effective than electric geysers. Propane heaters work in the same way, except propane replaces natural gas.
If you want a cost-effective instant geyser, then electric ones are fine. But for places where electricity is a problem, go for the gas geysers. It is wise to select a suitable fuel type for cost-effectiveness.
thermostat, Temperature Sensor & heating element
A temperature control sensor built inside the geyser, protects you by understanding and signalling the thermostat when the gadget reaches the ideal water temperature. Choose a water heater with a high-quality temperature sensor.
In an instant water heater, you will find a thermostat present inside the outer casing. It is a sophisticated instrument that controls the electricity supply based on the feedback from the water temperature sensors. Thermostats are crucial for consistent supply of hot water and improved safety.
The powerful the heating element, the faster it heats the water. As soon as you switch on a heater, the current passes through a heating element. Select the best instant geyser in India with the premium copper and incoloy heating elements that will continue increasing the temperature of the water rapidly. Crompton Bliss 3-L has a copper heating element with Nickel coating that counts for faster heating.
Wattage, BEE star rating & power consumption
BEE star rating determines whether a water heater is energy efficient or not. It is calculated based on the Standing Losses (kWh/24hour/45°C difference) measured as per IS 2082:1993.
The Bureau of Energy Efficiency (BEE) specified water heaters with 1 to 5 star ratings in the capacity range of 6 L to 200 L. As most instant water geysers in India come within the range of 1 L to 3 L, you won’t find any BEE star rating on them.
For example, Havells Instanio comes in 3 capacities- 1, 3, and 6 L. The 6 L model has a 5-star BEE rating, while the others do not have any such rating.
Apart from star rating, the power consumption can be calculated as per this formula:
Energy requirement in kWh = (Water Volume x Temperature Rise x 0.0012)
This formula tells you ideal energy usage in terms of kWh or units. But you must also consider the water heater’s weight and size, the amount of time you use, and its standing losses into consideration.
All the highly efficient instant heaters work on 4.5 kW. They are made to heat the water at a faster rate. But an instant geyser with 3 kW electricity consumption will work comparatively slow.
So, if you need a rapidly working instant heater, you need to select a higher power intake. If you want an energy-efficient machine, you need to choose products like Orient Electric Aura Neo Instant 1L Vertical Geyser that works on 3kW energy.
Unnecessary wastage of electricity can surmount a hefty electricity bill. So, calculate energy consumption and make wise choices to save electricity bills!
Water pressure and flow control
A water heater must tolerate extreme pressure. An example is Bajaj Flora Instant Geyser that can withstand 8 bar pressure. But others must be able to intake at least 6 bar pressure. So, a geyser with a higher amount of water pressure intake works well in a tall building. They fit well in any residence irrespective of height.
Also, temperature and pressure relief valves (T & P) must work fine. After you choose a water heater, you must frequently check these valves at least once in 6 months. In this way, you will avert any dangers with your heater.
Flow control valves are another feature that you must check while choosing. It helps you to control the flowrate of hot water. Installing a non-return valve will prevent backflowing of water. So, no dry heating occurs.
Storage Tank material and coating
There are mainly five water tank materials—copper, stainless steel, mild steel and thermoplastic polymer.
As copper is a great heat conductor, it does not retain much heat. But also, it does not corrode easily.
Similarly, a mild steel storage tank loses the heat faster and erode quicker than other materials. They are not long-lasting compared to stainless steel ones. Thermoplastic materials are also corrosion-resistant and have a good heat retention capability to warm the water faster.
Like the tank material, coating is also important to ensure longevity of the heater. There are mainly four types of water heater coatings-
- Porcelain Enamel Glass Line Coating
- Inner Tank Glass-lined Coating
- Vitreous Enamel Coating
- Polymer Coating
- Blue Silicon Enamel Coating
A glass-lined tank with enamel coating is best for the efficient performance of the geyser. Manufacturers mainly use the first two coatings over others that provide a higher corrosion resistance.
Also Read: Coating and Tank Materials of Water Heaters
Water hardness and TDS
Hard water simply means water with a higher mineral quantity. Mainly, magnesium and calcium can pile up inside a water heater. High TDS will decrease the water heating efficiency. As the geyser will need to go past these sediments, they would eat up more energy. So, you must check whether or not a heater can work with hard water.
The best instant heater with anti-scaling properties will work effectively with hard water. You must remove the scaling frequently to boost its efficiency. Apart from it, you can follow methods like magnetic water treatment to decrease any hard water residues. Using a water softener can also reduce scaling inside the geyser tank. Operating the heater at 60 degrees Celsius is another efficient tactic.
Intelligent features of instant water heaters
Anti-scaling properties are present in the water heaters we have mentioned. They have special filters to remove and prevent scaling. As we know, hard water and the minerals present inside it form scales. These scaling piles up to block the heater.
But a heater with a specific design implements isolation valves. These valves remove the scaling with no external help. You would need to replace the cartridge sometimes. Crompton Rapid Jet 3-L has an anti-scaling feature.
2. LED indicator
The LED indicators are a lot of help. It signals you about the heating status of the water. Some products like Bajaj New Majesty Instant 1 Litre, 3 KW Water Heater indicate two features. It lights a different color when you switch it on. They another when the water is hot. So, you can see that how LED indicators will ease your task. You can fetch warm water without any difficulty.
3. Auto turn off
Auto turn-off feature aids ensure safety. Whenever you forget to switch off the heater, an accident may occur. Prolonged heating can create thermal or electrical accidents. But an automatic shutdown prevents all such mishaps.
4. Overheating protection
Most of the best water heaters come with overheating protection to ensure operating safety. With such intelligent technology, the heater will turn off before any failure of the thermostat.
How to use an instant water heater efficiently?
- Place an instant water heater anywhere, but we recommend using the geyser near the electrical plug point and water supply. It can be your bathroom, kitchen, or near the sink. Installing the geyser at the right spot is crucial. It does not waste a single inch of space in this way.
- If you are using the geyser for the first time, open the flow control valves at the inlet and outlet. Now you need to switch on the heater. After you do so, the water will slowly start heating up.
- As the water fills into the instant geyser, you must let the appliance be on. But for how long? It depends upon the product you are using. If the heater consumes 4500W power, then it will take less than a minute to heat. However, if the geyser consumes lower power, then it can take a minute or longer.
- Any water heater has a neon indicator. Watch the indicator to understand the heating status. The color of the indicator will change as soon as the water heats up to a preset temperature. At the same time, the thermostat cuts off to avoid overheating.
- Now when you discharge the hot water, lower-temperature water will start filling up the geyser tank. The temperature sensor will detect it and signal the thermostat to turn on. So, if you do not need hot water any further, turn it off.
