With 325L storage capacity, 180L boost capacity, 3.6kW backup element, R134a refrigerant, two-piece system configuration, and suitability for up to 5 people under Rheem’s stated assumptions, it is a practical heat pump upgrade option for households wanting to reduce water heating energy use compared with standard electric storage.\u003c\/p\u003e\n\u003ch2\u003eAbout the Rheem MPi-325 Series II Heat Pump\u003c\/h2\u003e\n\u003cp\u003eThe Rheem MPi-325 Series II Heat Pump uses environmental heat pump technology to absorb heat from the surrounding air and transfer it into stored water.\u003c\/p\u003e\n\u003cp\u003eInstead of relying only on direct electric element heating, the system uses a refrigeration cycle to heat water more efficiently. Rheem positions the MPi-325 as using around one third of the energy of a standard electric water heater under suitable conditions, with potential water heating energy savings of up to 65% in Zone 3 when replacing an electric water heater of similar size.\u003c\/p\u003e\n\u003cp\u003eThe MPi-325 is recommended for replacement of small to medium electric water heaters across climate Zones 1 to 4. It is also designed to work day and night because it does not rely on roof-mounted solar collectors or direct sunlight.\u003c\/p\u003e\n\u003ch2\u003eBuy Rheem MPi-325 Supply
