Rinnai MC-45-4US Tankless Water Heater Digital Main Controller - White

Great Product

Great product and should be purchased with every Rinnai Tankless Water Heater. I have three in my house and it is great to be able to adjust the water temp with just a touch of a button. I install one in the Kitchen and one in each bath. They are very east to hook up also. Read full review

8 years of Rinnai

I purchased a Rinnai tank less commercial hot water system 8 years ago. I thought it would hold up better than one that was residential. The unit stopped working about two weeks ago. I bought a new Digital Remote Control but that was to no avail. It was all plastic and did not look to be a substantial product. So we disconnected the two wires on the old one and plugged in the new one. While the new remote worked, the unit was still didn't. I called my plumber and he looked at it and said the whole unit was shot. I did some research and found the Rinnai had some PVC parts and other parts that would not stand up to constant use. So I bought a Naviens system (with all stainless steel parts) Works like a charm.Read full review

Much needed controller for Rinnai

This is a must have for a Rinnai tankless water heater. Otherwise, you have no way to change the temperature of the water once your installer leaves.
