In the early 90s Rinnai forever changed the way Australians enjoyed hot water, with our launch of the country’s first fully electronic gas continuous flow hot water systems. It was a revolutionary leap that provided total confidence and comfort by knowing that your hot water would never run out. We called it Rinnai Infinity.
