Tankless water heaters are a significant innovation in heating water for your home. These units don’t have holding tanks that take up a lot of space in your garage or utility room, and they also don’t waste energy as a traditional water heater does. However, they do provide your home with an almost endless supply of hot water because they only heat water when it is needed.
The process is referred to as on-demand heating, and it only happens when you open a hot water valve in your home. The water is then heated as it flows through the pipes to the faucet or shower that requires hot water. The tankless units operate using either gas or electricity, just like the traditional water heaters. But they only use a fraction of the power consumed by the older models. And if that is not enough reason to choose the tankless water heater, consider that the average life expectancy for a tankless unit is over twenty years. To put that into perspective, a traditional water heater can be expected to last a maximum of about ten years.
