The 55132507 is a 325L Heat Pump Hot Water Unit Mpi-325 Series II from Rheem. The MPi Series Rheem Heat Pump utilises the latest environmental heating technology to efficiently heat water. Free, renewable heat energy is absorbed and processed through a refrigeration system, resulting in hot water using a third of the energy of an electric water heater. These are similar savings to a solar water heater, but without needing panels mounted on your roof.

  • Multi-pass heating – Heats the water ‘isothermally’ by passing the water through the heat exchanger multiple times
  • Constant recovery – Minimises energy use by heating at a ‘constant’, optimised rate
  • One man installation – can be fully installed by plumbing trades
  • Energy efficient – Cuts energy use and greenhouse gas emissions by up to 65%2,3
  • No Solar Panels – No structural load on your roof and looks better too
  • Back-up element – Provides hot water regardless of the weather
  • Whisper technology enables quieter operation
  • LED Display – Enables you to easily check the operating status of the water heater
  • Eligible for STCs5
  • Owner's Guide & Installation Instructions - MPi 551 Series
