Installation Tips
Save water by eliminating the wait for hot water to reach the tap. Simply tap into the cold water line and install the heater directly at the sink. No need for costly recirculating lines and pumps. And when you want to eliminate the wait for hot water but need more volume, install the Ariston heater in-line with a larger hot water source, such as a Bosch AquaStar tankless heater or a storage tank heater. Lightweight and compact, the 2.5 and 4 gallon models plug into a standard 110 volt outlet. The 6 Gallon Plus requires hard wiring and can be mounted vertically or horizontally. All models include a mounting bracket.
