Mitsubishi M-Series Hyper Heat Systems Hyper heat (or Hyper-Heating (H2i)) is Mitsubishi's advanced heat pump technology (using an enhanced compressor system) that delivers heat all the way down to -18° F. In 2007, Mitsubishi launched the residential Hyper-Heating INVERTER® (H2i).

Is Mitsubishi hyper heat worth it? It's more efficient (SEER Rating) while heating down to -13° F, and it's also energy star rated. If you're in a climate where extreme low temperatures are common, Mitsubishi's FH hyper–heat technology is probably a good fit for you.

Although running a Mitsubishi Hyper Heating system won't put a significant dent in your budget, you may expect to see an increase in your monthly power bill for each outside unit that remains operational within the house. However, this would eliminate the expenditures associated with acquiring oil, gas, or propane.

Conventional heat pumps only produce 100% heating capacity above 47 degrees Fahrenheit. In comparison, the patented Mitsubishi Electric Hyper-Heating heat pumps have the ability to produce up to 100% heating capacity at 5 degrees Fahrenheit and guaranteed heating capacity down to -13 degrees Fahrenheit.

Some estimates suggest that the cost of operating a Mitsubishi Hyper Heating system can be as low as $300 to $400 per year, depending on usage and cost of electricity. However, the cost can be higher or lower depending on the factors mentioned before.

With the Mitsubishi Hyper Heat™ heat pump, the efficiency rate will start to drop at around 2 degrees Fahrenheit. At -2 degrees, you will get around 87% of the unit's output. And at -13 degrees, you will get around 76% of the unit's output. It is unclear at what temperature the unit will stop working entirely.
