How to choose an Instant Water Heater?

Published on : September 29, 2021

Instant water heaters are gaining popularity among consumers, owing to their compact size and quicker heating. These water heaters are used for varied applications in households. Depending upon the requirement, consumers get them installed in the kitchen or bathrooms. Instant geyser water heaters are available in 1 and 3 liters capacities and feature high wattage of 3KW and, in some cases, 4.5KW for fast heating. These water heaters are easy to install and use. The selection of the right water heater is important for safe usage in the longer run.

There are various factors to consider before choosing the right instant water heater:

The crucial parameter while choosing a water heater is always its technology. Most important is the material and construction of the inner container (tank). Typically, Stainless steel (SS) is used; although SS has good corrosion resistance, the weld joints in the tank are prone to corrosion and leakage, especially in hard water conditions. A glass lined inner container is best suited for hard water applications as glass lining provides utmost resistance to hard water and scaling. Typically, an anode is also used along with glass lined tanks that provide an additional protection layer.

Instant water heaters should have a good pressure rating as these are increasingly being used in high-rise apartments and homes with pressure booster systems. A pressure rating of 8 bars is ideal for such applications.

Additionally, the thickness of the tank material plays a pivotal role in assuring a high-pressure rating and years of leak free performance. Glass lined water heaters typically have a 2mm thickness and are best suited for such applications.

The heating element plays a crucial role in providing consistently hot water as desired by the user. Heating elements made of Incoloy material are proven to provide long-lasting performance. A glass coating is also provided on the Incoloy element to enhance its durability further. So, while choosing your instant geyser, do keep it in perspective.

Compact and modern water geyser designs that go with the house decor are seen as winners in the Instant water heater segment. The outer body is typically made of polymer material. An ABS (a type of polymer) body provides best fit and finish and retains its sheen for years, which acts as a layer of insulation between the tank and surroundings. Instant water heaters should be compact to fit into tight spaces. The height of the water heater is important for installation requirements, especially for compact bathrooms where ceiling heights are shorter.

Installations of these compact geysers are relatively easier. Space and adequate power supply are the basic requirements for installing and starting it.

With the increase in demand, many Instant water geyser options are available in the market. However, considering the above parameters, it is crucial when choosing an Instant water heater to ensure peace of mind and seamless product performance.
