The Rinnai Plate HEX, Medium (807000184) is a genuine OEM replacement component for i-Series Plus combination boilers. The plate heat exchanger transfers heat energy from the primary heating circuit to the domestic hot water (DHW) circuit on demand, providing instantaneous hot water without the need for a storage tank. Over time, scale buildup or physical damage can reduce heat transfer efficiency. Replacing with this OEM heat exchanger restores full DHW capacity and performance.
