H2i P-Series outdoor units bring a new level of performance to Mitsubishi Electric P-Series models, furnishing the extra heat-generating power needed to deliver comfort and consistency in extreme climates. H2i units use Mitsubishi’s INVERTER-driven scroll compressor technology to achieve the desired room temperature quickly, maintaining it consistently while simultaneously conserving energy. Best of all, the integration of our exclusive H2i flash injection technology means these H2i P-Series units recover heat energy that is normally wasted in the flash process at the outdoor coil, overcoming issues associated with conventional heat pumps.What you’ll see is the H2i P-Series units deliver 100% of rated heating capacity at 5?F and 80% of rated heating capacity at - 13?F outdoor ambient temperatures without the use of energy-consuming electric-resistance heaters.
