Which Instant Heater is best for your home?

Selecting a water heater isn't just about the aesthetics but also about the type of building that you live in and the water pressure you experience in your bathrooms and kitchen. Let us help you choose the right one-

  1. High-rise buildings- We know that water pressure can be challenging at times due to the vertical distance that water needs to travel. If you live in such scenarios, then opt for an instant water heater with compatibility of up to 8 bars. We would suggest Primus 3 Litre Instant Water Heater from Orient Electric which checks all boxes for a good instant water heater online.
  1. Low-rise buildings- Generally the water pressure is between standard to high in such buildings thus you can consider a broader range of models online. Go for the one with pressure compatibility of 6 Bars for efficient use of hot water.
  1. Mid-rise buildings- Opt for a small instant hot water heater that has pressure compatibility of 6 to 6.5 bars for a consistent supply of hot water from the heater. Our favourite pick from the lot is the Rapidus 5.5 Litre Instant Water Heater. It is also the first in the industry to have a capacity of 5.5L and with the cutting-edge technology of providing hot water instantly.

How Does an Instant Water Heater Work?

They do offer numerous advantages as compared to the traditional storage tank water but are you not curious about how it works? We will help you make your decision quicker but with all the details that you need, so here is how Instant Geysers are able to supply hot water on demand-

  • When you turn on the pipe, cold water enters the heater through a pipe. A flow sensor detects the water flow and signals the heating element to activate.
  • The nickel-coated copper heating element then heats up to raise up the temperature. Then the water passes through the heat exchanger.
  • In the water exchanger, the heat from the element is absorbed to raise the water’s temperature to the desired level.
  • The hot water instantly exits the heater and reaches your faucets or shower. For as long as your water inlet is operating, this process continues, and the Instantaneous Water Heater will supply hot water continuously.

How to drain water from the Instant Water Heater?

While they are known for their low maintenance, do not forget to remove the mineral buildup as it can affect the efficiency of your heater. Here is how you can drain an Instant Water Heater-

  1. Turn off the power- Switch off the power supply to the water heater and turn the cold-water inlet to prevent any water from entering the unit.
  2. Locate the draining valve typically found near the bottom of the unit. Then attach one end of a garden hose to it and connect the other end to a desired drainage location. Close the drain valve tightly once the tank is empty.
  3. Turn on the cold-water inlet and let water enter the heating unit. You may hear air sputtering from the hot water taps, there is nothing to worry about as it's an indication that the air is purged out of the system. Done! You are all set to go! (Don't forget to restore the power supply.)
