Savings From Day 1
According to Crawford, installed costs on the Rinnai Demand Duo units were about half the cost of sticking with the same units the school previously used.
“The up-front price difference was huge,” said Crawford, “but what has really surprised us since then is how much we’re saving on gas every month.”
On average, Countryside High School saves close to 20% on their monthly utility bills since switching to the Rinnai Demand Duo units. The commercial ENERGY STAR® certified tankless units offer 96% thermal efficiency, yet deliver more stable temperatures and more hot water than the school’s previous units.
Crawford expects to reap more savings over the long run, thanks to the Demand Duo’s dependability and serviceability.
“They’re worth their weight in gold, because they’re so reliable and easy to maintain,” said Crawford. “I don’t have to babysit them all the time, like we did the old water heaters. I was spending a ton of money keeping the old units up and running.
“Rinnai’s factory folks even taught a free, on-site class for my shop people on maintaining and servicing the Demand Duo,” Crawford continued. “So, if the heat exchanger ever does fail, I can swap it out for a fraction of the cost of new water heaters. And with the redundancy of the units, we never lose hot water, even during servicing.”
