A tankless water heater is a heater that heats the water without the usage of a tank. The water is heated through a heat exchanger on demand. Most of the new homes that you see now are being built with these tankless water heaters due to their efficiency.
What is the biggest benefit of a tankless water heater as compared to the tank type heaters?
The biggest benefit of using a tankless water heater is that you get an endless supply of hot water instead of a limited one. As for traditional water heaters, you only get hot water until the tank’s supply is depleted.
If a tankless water heater doesn’t have a tank, how does it heat water?
The working of a tankless water heater isn’t as complicated as some people may think. It heats the water as it flows through the tubing in the heat exchanger inside the heater.

Is this water heating technology new?
No, in fact, this technology is pretty old but you can say it has been “matured” now. Mature means that the device has been determined to be developed to the point that it is considered reliable and that drastic changes to the components of the device in the near future are unlikely.
