What can EVI achieve?

EVI refers to "Enhanced Vapor Injection" and is the technology used to achieve higher performance at lower temperatures for our cold climate heat pumps. Enhanced vapor injection systems (EVI systems) can： effectively improve vapor compression cooling; effectively improve the cooling or heating performance of heat pump systems; improve cooling or heating performance coefficient; reduce emission temperatures.

What is the appropriate heating capacity of an air-to-water heat pump for a house of 140 to 150 m2?

For heat pump installation in a house of 140 to 150 square meters, we plan to use a 9.8 kW heating capacity. We recommend a 10-20% uplift space to create warmth faster. For this reason, you must choose a heat pump with a capacity between 10kW and 11kW.

10kW, 11 kW air-to-water heat pump price
