NR981 Series Residential Tankless Water Heaters
Unlike with a conventional tank-type water heater, the hot water is always there when you need it with a tankless water heater. With a tankless water heater, water is heated as it passes through the unit so you will always be using a fresh supply of water. A Noritz Tankless water heater provides a continuous flow of hot water, so there’s no need to suffer through a cold shower if you’re the last one out of bed, and there will always be plenty of hot water instantly ready for other uses when you’re done.
