Mains Pressure Heat Pump

The Rheem Mains Pressure Heat Pump is designed with the smaller family in mind.

  • Provides hot water at a third of the cost of a standard water heater.
  • Smaller compressor allows a lower operating noise level making the MPi-325 one of the quietest on the market.
  • Large 325 litre cylinder allowing the heat pump to run at a constant optimised rate.
  • Back up element is also fitted with this model.
  • Although the cylinder is 325 litres this system would suit a household using up to 200 - 250 litres of hot water per day.
  • Simple two piece design allows for easy installation by one person.
