After a long day on the road, all that most visitors want on arrival to Ruby’s Inn, near Utah’s Bryce Canyon National Park, is a hot shower. But with busloads of tourists arriving at once, the 700-room resort was struggling to keep up with hot water demand. The resulting cold showers were enough for some guests to ask for their money back, causing the resort to lose around $60,000 each year in discounts and refunds. To avoid further losses and ensure patrons could relax upon arrival, Ruby’s Inn worked with Rinnai to overhaul its water heating system.

Watch the video below to see how replacing storage tanks with more than 200 tankless units, rack systems, and demand duos improved hot water capacity in guest rooms and elsewhere throughout the 19-building property while saving 7,000 gallons of propane per month.
