Low Temperature EVI Heat Pumps

SPECIFICATIONS

DESCRIPTIONS

It is designed with the most advanced low temperature enhanced vapors injection (EVI) technology for hot water and floor heating in extremely cold areas, The R417A refrigerant is standard for this series which is also helpful to get better performance in low ambient temperature.Heat pumps are one of the best heating options because due to our moderate climate, they're highly efficient to run.What's even better is that most of the energy they use comes from renewable sources, so they're an environmentally friendly way to heat and cool.They provide many other benefits too. They help you save money on your home heating bills, clean the air in your home, and dehumidify your home in hot summer months.
