Best Instant Water Heaters in India For Quick Warm Showers

Instant water heaters have gained popularity in the recent years for the convenience they offer. So, you don’t have to wait for hours to get hot water.

Unlike other water heaters, they don’t have water tanks. They heat water instantly based on the demand instead of heating a full tank of water.

They are perfect for small families and couples. As they are compact in size, they are an ideal choice for placing in kitchens and bathrooms with space constraints.

If you are looking for the best instant water heater in India, then browsing through the extensive range of models can be a daunting task.

For choosing the right one among them, you have to consider the below three main factors.

1. Size or Capacity

The capacity of instant water heaters in India range between 1 to 3 litres. Some of them can provide as high as 6 litres. You have to choose the capacity based on your requirements. Below is table representing capacities and their standard recommendations.

Capacity Family Size Recommended Use
1 litre Bachelors or individuals Face wash and washing utensils
3 litres 2 to 3 members Washing utensils and bucket bathing
3 litres 4 to 8 members Hand wash and washing utensils
6 litres 2 to 4 members Washing utensils and bucket bathing

2. Wattage

You have to consider a simple rule while analysing this factor – higher the wattage, quicker will the water be heated up. For example, 4.5K wattage model heats up water quickly compared to 3K wattage model. But the higher wattage levels also impact the pricing. So, choose wisely based on your budget.

3. Bar Pressure

It represents the pressure of water which hits the water heater tank. If you live in high rise buildings, then 8 bar pressure geysers are the right choice as they handle the pressure properly. If you live in individual homes where water pressure is low, then instant geyser with 6 or 6.5 bar pressure is suitable.

In addition to these, there are other factors like water tank material, heating element, outer body material and others to consider. We have mentioned them clearly in our Buying Guide for your reference.

Using the same information and hands-on testing for over two months duration, we have shortlisted the best instant geysers in India that are perfect for your bathroom.
