Mitsubishi ECODAN PUZ-WZ R290 9 kW Monobloc Air Source Heat Pump

The Mitsubishi Electric ECODAN PUZ-WZ R290 9 kW is a monobloc air source heat pump designed to deliver high energy efficiency and year-round thermal comfort. Thanks to the use of natural refrigerant R290 and Mitsubishi Electric’s ECODAN technology, this unit is an ideal solution for residential projects seeking sustainability, reliability, and stable performance even in demanding outdoor conditions.

System Type and Application

As a monobloc system, the entire refrigeration circuit is integrated into the outdoor unit, simplifying installation and eliminating the need to handle refrigerant on-site. The connection to the interior is made via a hydraulic circuit, making it easy to integrate with heating, cooling, and domestic hot water production systems.

With a nominal output of 9 kW, this heat pump is suitable for medium-sized single-family homes, with recommended surface areas depending on insulation level, emission system, and actual thermal load calculations.

R290 Refrigerant and Sustainability

R290 (propane) is a natural refrigerant with a very low global warming potential, allowing for high supply temperatures while maintaining excellent efficiency. This makes the unit especially suitable for both underfloor heating and existing radiators, while also contributing to emissions reduction and compliance with current environmental regulations.
