You don't have to worry about running out of hot water again. Our innovative technology provides an endless supply of hot water whenever and wherever it’s needed – even for simultaneous uses at multiple fixtures. Back-to-back showers and baths? Absolutely. Laundry and dishes at the same time? No problem. Prioritizing activities and scheduling hot water use is a thing of the past. Designed for efficiency: Rinnai’s tankless technology features durable heat exchangers to provide maximum efficiency and uses up to 40 percent less energy* than a traditional tank.
By operating only when hot water is needed, with pilot light and no storage tank to heat and reheat water, our tankless technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly uses energy.
