Instant water heater benefits

Ideal capacity:

An instant water heater is just of the right capacity for usage in a household of about 3 to 4 members. You can even get it in a single liter capacity if you live in-studio flat and want to use your heater for minimal kitchen or washroom use. A three-liter instant water heater can be used for bathing or household chores, and while six-liter instant geysers models can help a family of over four members, too.

Compact size:

The ideal capacity of the water geyser further leads to its compact size. A water heater of 3 liters or even six liters can be easily installed in most households, however small. They can be used in the bathrooms or even set up in the kitchen without much hassle. 

Ease of installation:

Several instant water heaters come with free installation and can be set up easily in your home. You will just have to buy a few accessory pipes if they are not already included and complete the installation process. Hence, this is far less intimidating than the installation process of storage water heaters. 

Heats up water instantly:

The one thing that sets apart instant water heaters is that they heat the water in relatively less time than used by other conventional water heaters or storage geysers. Now, you will not get late to go to work as you sit and wait for the water to get heated, or you can quickly get a few more minutes of sleep as you do not have to wake up early to switch on the heater. 

Gentle on your budget:

Your instant water heater will go gentle on your budget and not worry you with excessive electricity bills. You can choose an instant water heater of suitable power consumption and get the luxury of hot water without it burning a hole through your pocket. 

Instant water heater factors:

Geyser storage capacity

Though instant water heaters come in a limited capacity range, the range is advantageous for small households. Instant water geyser may range up to six liters, beginning from one liter. 

Wattage of the heater

Instant water heaters that come with higher power consumption or wattage heat water faster. The heaters come only in a limited budget-friendly power consumption range, which is 3000 watts or 4500 watts. A heater with 4500 watts will heat water faster than the 3000 watts heater. 

Water bar pressure

The pressure at which water hits the heater tank is known as the water bar pressure. Heaters are available in higher bar pressure, such as 8 bars, which is ideal for high-rise buildings, or about 6 to 6.5 bars, perfect for houses. 

Tack material

The geyser tank can be made using a range of materials, out of which copper, thermoplastic, and steel are some commonly used materials. Corrosion-free steel is the best heater material you can use as it has more extended heat retention capacity than both thermoplastic and copper. You can use a glass-lined thermoplastic or copper heater, as the lining helps to retain the hot water temperature. Also, vitreous enamel coating helps the stainless steel material remain corrosion-free.

Heating element

The heating element of the heater ensures how quickly the tank water will be heated. Coated copper heating elements and glass-coated Incoloy heating elements can work up to four years, even in hard water, and are resistant to corrosion. The cheaper option is glass coated copper, which works up to two years in hard water.
