Thanks to the full-inverter technology, the Inverter Heat Pump adapts the speed of its compressor from 20% to 100% unlike traditional heat pumps which only operate at a single speed until they reach the desired temperature. The result? A much lower operation cost and a more accurate and durable technology. Just like its little sister the Moov Reversible, the Moov Inverter heat pump works with reversible valve defrosting. Considered to be the best way to defrost the product at low temperature's, this approach allows the product to operate in the opposite direction to its usual tendency, thus allowing accelerated defrosting to then heat better.
