How big is a tankless water heater?

Most Rinnai tankless water heaters are only about the size of a rolling suitcase. The dimensions vary slightly based on the model you choose. Not only are tankless water heaters more efficient, they’re also convenient for installation in small spaces. Some models can even be installed indoors or outdoors, based on your needs.
