THE SMARTER WAY TO DO HOT WATER
For nearly six years, since it opened in 2011, the Mainstay Suites Winnipeg had relied on
four leaky, inefficient 80-gallon atmospheric hot water tanks. Not that long ago, guests
at the Mainstay Suites Winnipeg Hotel might face a rude awakening in their morning
shower when the hot water ran out. But now, since 4 Rinnai’s Demand Duo
®
Hybrid units
were installed in June 2017, the hotel is running at full capacity, and both guests and
management are happy with the change. Combining the best of both tank and tankless
design, Demand Duo delivers hot water so efficiently that the hotel’s natural gas
savings have totaled more than $9,000 in the first eight months, despite the
colder-than-normal winter.

George Family Farm | Agriculture
HIGHPERFORMANCE KEEPS HIGH TEMPERATURE
In Upstate New York, the George Family Farm runs a dairy business with more than
700 cows producing dairy products for stores across the country. One of the most
energy-intensive functions on a dairy farm is heating water and this capability is directly
linked to the farm’s profitability. For processing milk products, water must be 160-180°F
to effectively clean the lines and the farm’s old water heating system only delivered
120° to 140° resulting in milk fat buildup so the farm could not produce Grade A milk.
By replacing a traditional tank with Rinnai’s high-performing tankless units, the Georges
can maintain hot water at the desired temperature 24 hours a day and the farm’s milk
can now be sold as top grade, earning them tens of thousands of dollars in additional
profit per year.
Countryside High School | Education
SAVINGS FROM DAY ONE
For years, the Pinellas County School System, located in the Tampa Bay area of Florida,
relied on traditional tank-style water heaters that lasted typically only six to eight years,
at the most. “With such a short life span, I knew there had to be a better alternative,” said
Ty Crawford, in charge of maintenance for the school system. Since October of 2016,
when the Countryside High School installation took place, the Pinellas County School
System has replaced tank-style units in another seven schools with Rinnai’s Demand
Duo Hybrid Water Heating Systems. “If the heat exchanger ever does fail, I can swap
it out for a fraction of the cost of new water heaters.” On average, Countryside High
School saves close to 20% on their monthly utility bills since switching to the Rinnai
Demand Duo units.
