Plus, you can save a lot of electricity and such a water heater won’t be running ideal and the heat won’t be ultimately used.

How Does An Instant Water Heater Works?

With the tankless water heater, the water is heated directly without using a storage tank. So, when the hot water tap is turned on, the cold water will travel through the pipe right into the unit. Here either an electric element or gas burner will heat the water. 

Now, this is the reason the tankless water heater can provide a constant supply of hot water. The best part is that you won’t have to wait for the storage tank to fill up and that too, with enough hot water. But the tankless water heater’s output limits the flow rate. 

If you check typical tankless water heater can provide hot water at a rate of 2-5 gallons per minute. Additionally, gas-fired tankless water heaters would produce higher flow rates compared to the electric ones. At times, even the largest and gas-fired model won’t supply enough amount of hot water, and that to various large households. 

The other applications that demand water heaters consist of the – 

● Booster for appliances like clothes, washers, and dishwashers.

● Remote bathrooms and hot tubs.

● Booster for solar water heating systems.

Advantages Of Instant Water Heater

Some of the major advantages are – 

● The instant water heaters are more than the normal products that you see in each household.

● Priced cheaply, it can store a huge amount of water all at once. Unlike other instant water heaters, there aren’t any kind of breaks in between. You get a continuous supply of hot water. 

● Such instant water heaters are quite suitable for use in the bathroom and have a storage capacity ranging from 6 liters to 30 liters.

Having a large storage space, such instant water heaters would take a huge amount of space, and you would need a large wall-mount for hanging it in the bathroom. You also need to wait for 5 minutes before getting hot water, which can be annoying at times.

Disadvantage Of Instant Water Heater

● The instant water heater can’t supply the required amount of hot water simultaneously, like laundry and showers. 

● Unless the system is equipped and modulates temperature control, it won’t heat the water to the constant temperature and at various flow rates. So, this means that water temperature will fluctuate uncomfortably. Also, the water pressure will vary in various parts of the house. 

● Electric instant water heaters need high relatively electric power, and they can heat water faster and that too at the required temperature. In certain cases, electric services will have to be upgraded.

● Tankless instant water heaters have to be vented outdoors, and these are either with a direct vent or conventional kind of exhaust fire.

● Some of the instant water heaters would be gas-powered, and their unit will have a pilot light. Plus, it will lead to a waste of energy. 

Things To Consider For Purchasing Best Instant Water Heaters In India

Unlike in the older days, when you are using a water heater, you would have to wait for hours to get the water heated for your bath. With an instant or tankless water heater, you get instant hot water right on-demand rather than waiting for the tank to get filled with water and heating the water like a storage geyser.

Additionally, the instant water heater has limited storage capacity, and they are perfect for families containing 3-4 members. Besides being compact, they are the best choice for the kitchen and even smaller bedrooms that contain space constraints. 

► Water Heater Size

Regarding the capacity of the instant geyser, it varies from one liter to 3 liters. Also, you might come across a few models with less than 6 liters as capacity. Plus, you can choose the size based on the total members of the family. 

► Geyser Wattage

The higher the wattage of the water heater, the faster the heating would be. The instant water heater comes around 3000 watts (3kW) or 4500 (4.5kW). Compared to the 3kW instant geyser, the 4.5kW will be able to heat the water faster.

► Tank Material

The material with which the tank is created is based on the quality of the geyser. Also, its quality would have a direct impact on the efficiency and durability of the geyser. Here generally, the water heater tank is created using thermoplastic, copper, and stainless steel.

Also Read: Coating & Tank Materials of Water Heater

► Heating Element

The heating element is a significant factor compared to other factors. Now, most brands would be using copper heating elements and a coating to prevent corrosion materials.

Certain manufacturers use glass-coated Incoloy heating elements, and these are considered to be the best ones in the market for preventing corrosion. Even though they are expensive and would last for four years, too, with hard water as the major source, another major option is the glass-coated copper heating element. This would work better and is not expensive. The copper-heating element can last for two years, and it can be used for treating hard water.

Hardness Of Water

As we know, the hard water can create scaling right inside the geyser’s water tank. This will lead to huge damage to the heating element present too. Due to this, the corrosion will occur faster, and you would need to repair the geyser quite frequently or end up purchasing a brand new one. 

► Power Consumption

Besides falling for the marketing gimmicks, you would need to think about purchasing a good water heater that is energy-efficient. The energy efficiency of the water heater helps to determine or is determined with the energy star rating. The higher the BEE (Bureau Of Energy Efficiency) star rating, the lesser consumption will be. Also, it will increase the lifespan of the heater.

► Bar Pressure

The water pressure present in the water heater can be easily measured right in the bar. The bar pressure would mean that the water pressure gets hit the geyser or heater’s water tank. 

Here this pressure would vary right from building to building. For example, if you live on the 4th floor of the four-storeyed building, then your home’s water pressure will be lesser than the ones living on the ground floor. 

So, here when the water pressure comes into direct contact with the water heater tank’s inner walls, there is a huge chance that the inner walls become thin and they can get damaged over a while. At times, the water would start leaking from the geyser tank.

► Fuel Type

The instant water heaters are based on two kinds of fuel types. One is gas and electricity. In India, using natural gas as a fuel alternative can be a bit tricky. So, most of the models would be electricity-based ones. Plus, these models can be convenient ones when it comes to power consumption and installation.

► Price

It is easy to get a good and instant water heater at Rs 2000 and Rs 3000. The price would be based on the capacity that is provided along with the wattage used. Now high capacity tank and higher wattage will cost a bit more than the regular-sized geysers. Most importantly, the tank material and the heating material used would greatly impact the instant water heater’s price.

► Warranty

The water heaters are most prone to various kinds of damages, and these are ones concerning houses having a hard water supply. They need regular maintenance and servicing. It is also necessary to purchase a geyser from a reputable brand providing a good warranty and even after-sales service support. 

Sometimes you would face issues while providing geyser for serving, especially when purchasing a local or lesser-known brand. Certain brands provide a warranty of 4-5 years present for the tank and 2-3 years present for the body and other major parts of the geyser. 

Features Of A Good Instant Water Heater

● LED Indicator

Here most of the water heater would come with 2 LED indicator options, where the red and green colors are used. The green color displays the power on or off, and the red is for the heating element. 

● Auto-Off Feature

Using the auto-off feature, the heater will get turned off automatically when it reaches a certain temperature. The feature is also quite useful n saving electricity and even securing the heater from all kinds of damage and burning. At times you might be having the habit of forgetting to switch off the heater after usage, then this feature can be pretty useful.

● Temperature And Pressure Control Valves

Nowadays, certain manufacturers would provide temperature and pressure relief valves or the so-called T & P valve and high bar pressure.

Here the T & P valve will relieve the excess temperature and pressure present in the heater. These will be done when it reaches a critical point.

The closed water heater system’s thermal expansion is an inescapable fact that functions for both the abnormal and normal water heater. When you check out the standard water heater, the water will be heated using either the gas burner or electric element.

So, when the water temperature reaches around 120-140 degrees Fahrenheit, both the water and the heater’s metal tank would begin to expand. A small expansion would also be considered normal and too, with huge expansion being an unsafe one.

● ABS Plastic Body

The Acrylonitrile Butadiene Styrene) the plastic helps in avoiding the accumulation of rust. Also, it provides a shock-free body for various users. 

● Fire Retardant Cable

Such cables are very helpful in limiting the fire’s spread whenever there is a short circuit.
