Frequently Asked Questions ("FAQ")
Q1: What is the difference between the RU, RUR and RUC series?
A1: Rinnai's RU series heaters such as the RU80e and RU90e are simply the outdoor versions of the RUC units.
The RUR series heaters such as the RUR98i and the RUR98e have a built-in recirculation pump. The RUC series heaters such as the RUC98i and the RUC80i do not have the recirc pump.
All of these heaters are condensing.
