The Eemax electric mini tank can save the wait for hot water to reach a faucet. Simply tap into the hot water line and install the heater directly at the sink for instantaneous hot water. There is also no need for costly recirculating lines and pumps. These units are lightweight, compact and plug into a standard 120-volt outlet. Sizes include: 1, 2.5, 4 and 6 gal. The mini tank is wall- or floor-mountable, has a glass-lined tank for longer life and quick recovery time.
