The new heat pumps of the PUHZ-SHW series with the patented Zubadan technology.

The cutting-edge technologies for cost-effective and efficient heating and cooling.

Due to the most advanced technologies and a high-performance compressor, the new PUHZ-SHW have much better specifications than their predecessors of the PUHZ-HRP series. PUHZ-SHW series heat pumps are the leaders in the market based on the seasonal coefficients of performance and the amount of heat released at the extremely low ambient temperatures.

These devices are designed for heating, preparation of domestic hot water and cooling. Unlike any other traditional heat pumps in the market, the MITSUBISHI ELECTRIC units with the patented ZUBADAN technology maintain the constant nominal heating power in the outdoor temperature of down to -15°C, and the manufacturer guarantees a cost-effective supply of heat in the outdoor temperature of down to -28°C.

Outdoor devices of a PUHZ-SHW heat pump may be matched with indoor devices of both the air-to-air system and the air-to-water system.

In order to ensure safe operation of a heat pump in extreme outdoor weather conditions, MITSUBISHI ELECTRIC recommends using wind/snow guards. These are special covers which protect the outdoor unit of a heat pump from cold winds, snow and hail as well as enable the reduction of the duration of auto-defrost of an appliance and extension of the operation time between auto-defrost cycles. This reduces electric power consumption and ensures a smoother and longer service of a heat pump.
