Switched from Rinnai to Rheem. The Rinnai unit would cause a cold water sandwich effect - phenomenon where the water from the heater is warm for first few minutes, then there is a burst of cold water, and then the water slowly returns to being warm again. The Rheem unit is consistently the same temperature. This might seem minuscule, but it matters when you least expect it, especially when trying to get ready for your day at 6 AM.
