You don’t use hot water 24 hours a day, but you’re paying to heat water all day long. With a standard water heater you heat and reheat the same water… even when you’re sleeping. Rannai Hot Water tankless heating technology is a more efficient way to heat water while saving money and recapturing valuable space in your mechanical room.
Using the latest in gas technology, it heats water on-demand and delivers an endless supply of hot water for as long as you need it. Offering personalized control for your convenience, comfort and safety.
All Rinnai interior units utilize an exclusive cool-to-the-touch vent system that is sealed combustion and requires only one penetration through the roof or sidewall. Rinnai interior units can mount almost anywhere and can have a vent up to 41 feet long.
