Rinnai RL75EP Specification

Brand: Rinnai

Model: RL75EP

Type: Specification

Rinnai RL75EP is a continuous flow, gas hot water system that provides endless hot water for your home. With a minimum flow rate of 0.26 GPM and a maximum flow rate of 7.5 GPM, it can easily handle multiple hot water demands simultaneously. It features an electronic water control device and a fixed bypass for precise temperature control. The RL75EP is also energy-efficient, with an Energy Factor of 0.82 for both natural gas and propane models.
