The Rinnai Tankless Water Heater Revisited - I blogged about these units 2 years ago when the jury was still out. Well now the jury is in, and I am no longer a skeptic. They really work and they work really well. I saw them all over England and Europe a few years ago, then they appeared at the condos at our ski resorts. Utah has 14 ski resorts and 10 are in the Salt Lake City area so we inspect a lot of these condos. Most of these condos are rentals and time shares so they sit vacant most of the time. So the on demand tankless water heaters made great sense.
Now we are seeing these water heaters in more and more homes. The most common is the Rinnai Model R85. Last month we had several large vacant homes at Sundance with R85's installed so we put them to the test. We ran the hot water at every sink, tub and shower for 20 minutes. The thermostat was set on the Rinnai to 130 degrees. After 20 minutes the water coming out of the master shower was maintaining a constant 120 degrees. I remain almost awestruck at the performance of these tankless water heaters.
