Every year billions of gallons of water are wasted as we turn on the faucet and then wait for hot water to arrive. Save water by eliminating the wait for hot water to reach the tap. Simply tap into the cold water and install the Ariston Pro Ti directly under the sink, without any need for costly recirculating lines and pumps. And when you want to eliminate the wait for hot water but nedd more volume, simply install the Ariston Pro Ti in-line with a large water heater. The new "Titanium Plus Inside" glass lining protects the tank against leakage.
