I believe many of you may know the technicalities of water heaters. If that is the case, I suggest you read this Water Heater Buying Guide and then return to this article.
What Is An Instant Water Heater?
There is no water tank in an instant or tankless water heater. The water gets heated when it passes through the heat exchanger in the water heater. It is called an on-demand water heater; you will get hot water when required.
It is also called an Instant Water Heater, as you will get hot water almost instantly. Traditional storage water heaters take around 10 minutes to give hot water. An instant water heater does not have any space to store hot water.
Tankless water heaters are energy efficient, consume less space, and provide instant water. That is why these are preferred among consumers.
How Does Instant Water Heater Work?
When there is a demand for hot water, water passes through the heat exchanger of the water heater and gets heated. The heater unit sensor will only activate when it senses the water flow.
How much water your water heater can heat depends on the flow rate. For example, when we talk about a 3-liter instant water heater, it can heat up to 3 liters of water per minute. It does not have anything to do with storing water.
Tankless water heaters are powered by either electricity or gas. Gas is preferred if you want to use multiple outlets for hot water. However, the initial investment is more.
