Generally most of the regular tank heaters come with a flow rate of 4 gpm to 8 gpm. If the flow rate falls below these levels the energy efficient rinnai unit will turn off because it senses that hot water isn t needed. But tankless water heaters are complicated and difficult to diagnose.

This question requires identification by sight of a rinnai flow sensor or flow control assembly. They use a small computer so they can supply hot water as long as it is needed on demand and in continuous supply and at a preset temperature.
