Mitsubishi ECODAN PUZ-WZ R290 5 kW Monobloc Air Source Heat Pump

The Mitsubishi Ecodan PUZ-WZ50VAA-BS monobloc air source heat pump with 5 kW output provides heating and cooling through a fully hydraulic system using environmentally friendly R290 refrigerant (GWP 3). This unit does not include a DHW tank; to produce domestic hot water, an external storage tank and an FTC controller (e.g., FTC6 or FTC7) with a three-way valve and tank sensor are required.

Key Features

• Nominal thermal output: 5 kW
• Efficiency class: A+++ (35 °C) / A++ (55 °C)
• Water temperature: up to 75 °C with –15 °C outdoor temperature
• Operating range: –25 °C ↔ +24 °C (heating)
• Refrigerant gas: R290 – 0.6 kg (GWP 3)
• Sound level: 52 dB(A)
• Dimensions: 1020 × 1050 × 480 mm – 89 kg

Efficiency and Sustainability

The PUZ-WZ series houses the entire refrigeration circuit in the outdoor unit, eliminating the need to handle refrigerant indoors. Its wide modulation range optimizes compressor operation and reduces electricity consumption, achieving A+++ efficiency even under severe conditions.

Installation and Comfort

Its acoustically insulated structure and low noise level make it suitable for installation in residential areas. When combined with an Ecodan hydraulic module or compatible tank, it provides comprehensive climate control and a clean, efficient alternative to fossil fuel boilers.
