Rannai tankless

Installed few. Never had to work on one yet. Got a call, water getting cold at showers. Checked all the sinks, endless hot water. Turn on hot water at shower, 1 minute, cold water. Found out shower heads were clogged. Changed them out, worked fine. Just thought I would share this in case someone else runs into it.
