Changing market trends in India

The demand for water heaters has witnessed a significant rise in the past few years, making them one of the fastest-growing home appliances. Owing to the adoption of personal decentralized water heaters, the product has become a major market contributor.

The growing demand for hot water in residential areas for multiple purposes, coupled with rapid urbanization and a shift towards comfort, is determining this market growth. Moreover, the increasing awareness about the benefits of smart water heaters and online availability is positively influencing the Indian industry. By the year 2028, the Indian water heater market is expected to reach USD 422.78 million.


Things to consider while buying an electronic instantaneous tankless water heater

With the introduction of different kinds of water heaters in the market, choosing the right one for your needs might seem like a challenge. We have electric storage water heaters, solar water heaters, heat pumps, hydraulic tankless water heaters, and electronic tankless water heaters to choose from.

Electronic instantaneous tankless water heaters are the most energy-efficient water heaters in today’s market. However, there are some things to consider before opting for electronic instantaneous tankless water heaters. Hence, we have created a checklist to see if and which tankless water heater can be selected.


Flow rates of bathroom fittings

The electronic tankless water heaters are on-demand hot water systems. Therefore, the number of users, or occupants in a home or building, does not have any impact on choosing the model. Instead, the choice of an electronic tankless water heater should be based on the flow rates of the bathroom fittings, such as taps, showerheads, rain showers, bathtubs, body jets, and health faucets. These fittings have specific flow rates that dictate the amount of water that can flow through them per minute, measured in liters per minute (LPM).

To ensure that an electronic tankless water heater can provide sufficient hot water to meet the demand of these bathroom fittings, the flow rate of the electronic tankless water heater must satisfy the flow rate of any one fixture with the maximum flow rate.


Energy rating

Water heaters regulate a significant part of the electricity bill. So, choosing a 5-star rated online geyser will prove beneficial in the long run. Since electronic tankless water heaters are not manufactured in India, you need to follow the European energy rating class for the highest energy efficiency.

European energy rating standards provide a consistent method of measuring the energy efficiency of appliances such as electronic tankless water heaters. To ensure that an electronic tankless water heater meets the energy efficiency requirements in India, it should be rated Class A or higher according to European energy rating standards. This will ensure a corresponding energy efficiency equivalent to or higher than 5 stars as per Indian regulations.

By selecting an electronic tankless water heater with a high energy efficiency rating, you can save energy and reduce your energy costs over time. This can also have environmental benefits by reducing your carbon footprint and conserving natural resources.


Electrical infrastructure of the dwelling

A robust electrical infrastructure is required to support the operation of an online electronic tankless water heater. Unlike traditional water heaters, which heat and store a set amount of water, tankless water heaters use electricity to heat water on demand as it flows through the unit. This means they require a reliable and sufficient electrical supply to operate effectively and safely.

Electronic tankless water heaters come in both single-phase and three-phase versions, which refers to the number of alternating current (AC) electrical phases used to power the unit.

Different models of electronic tankless water heaters also require different wire thicknesses and safety MCBs, which are designed to protect the unit and prevent electrical overload. The wire thickness required can range from 2.5 sq. mm to 10 sq. mm, depending on the unit’s power requirements, while safety MCBs can range from 20-50 amps.


Technical features 

Some important features one must look for before finalizing an electronic instantaneous tankless water heater are listed below:

  1. Buy a tankless water heater with a bare wire heating system IES® for optimum heat exchange and energy efficiency.
  2. Ensure that the system is electronically controlled with maximum variation in power output for the highest comfort and minimum energy usage.
  3. Use tankless water heaters with a safety protection class of IP 25.



It is extremely important to check the warranty before purchasing a water heater. Generally, different parts of a geyser have different warranty periods. So, understand all the terms and conditions carefully before buying one.
