Can I use a recirculation line with Rinnai Tankless Water Heaters?

Yes, a recirculation pump can be a great addition to your Rinnai tankless water heater system when continuous, on-demand hot water is needed. Plus, the modulating technology and minimum fire rating of the Rinnai tankless rack system enables it to maintain consistent temperature in a return line with limited waste. In that case, it only uses the energy necessary to keep the line heated when in use.
