What is the primary advantage of a tankless water heater?

The primary advantage of a tankless water heater is that it provides instant hot water. Unlike traditional water heaters that store a specific amount of heated water in a tank, tankless systems heat water on demand. This means that you can have a continuous supply of hot water whenever you need it, without having to wait for a tank to refill and reheat.

The efficiency of tankless water heaters allows them to operate only when hot water is needed, which can lead to energy savings over time. This on-demand operation is particularly beneficial for households with high hot water usage, as it eliminates the risk of running out of hot water during peak usage times.

While other options may highlight features that tankless systems might offer, such as potentially requiring less maintenance or being more energy-efficient, the fundamental advantage lies in the immediate availability of hot water when it is needed.
