According to this study carried out by Consumer Reports, tankless water heaters are an energy-efficient way of getting hot water.
Their ability to process large amounts of water without storing it allows these models to consume 22% less energy than tank-carrying water heaters.
Their space-saving design is another notable feature of tankless heaters. Since they don’t have to use tanks to store water, these products can afford to be small and compact.
This is precisely the reason why you can install them in tight spaces with minimal fuss.
On top of everything else, these units justify their high initial asking price by delivering a constant supply of hot water.
When a hot water tap is opened, an electric element or gas burner heats the water as it travels through the pipe. That means you won’t have to wait to get hot water at the tap.
