Get endless on-demand hot water, space savings, eco-efficiency and peace of mind from the world's most reliable tankless gas water heater brand. Whether you need a residential water heater or commercial water heater, a Rinnai® tankless water heater will meet your needs. It's time to expect more because you deserve it.
Tankless water heaters require very little space compared to traditional storage water heaters.
When you turn on the hot water tap, the cold-water travels through a pipe and into the tankless water heater where it is instantly heated by either a gas burner or an electric element.
This gives you a constant supply of hot water.
