September 16, 2026

Mitsubishi Electric Sales Canada Inc. is pleased to announce comprehensive warranty coverage for the Ecodan WUZ, one of the newest additions to its hydronic heating portfolio.

Designed specifically for Canada’s climate, the all-in-one air-to-water heat pump system delivers efficient hydronic heating, cooling, and domestic hot water production in a single solution while simplifying installation for contractors and enhancing long-term confidence for homeowners.

The Ecodan WUZ is backed by one of the most comprehensive warranty programs in the residential air-to-water heat pump category, offering 10-year or 12-year parts and labour warranty coverage through Mitsubishi Electric residential dealer programs. Speak with your local Mitsubishi Electric distributor for complete warranty details.

Part of Mitsubishi Electric’s Ecodan family, which has been installed throughout Europe since 2011, the Ecodan WUZ benefits from years of field-proven performance in hydronic applications. Built with a refrigerant split configuration, the Ecodan WUZ eliminates freeze risk in outdoor piping by keeping the water circuit indoors. This design removes the need for glycol or heat tracing while streamlining installation and reducing maintenance requirements.

The Ecodan WUZ features Mitsubishi Electric’s Hyper-Heating INVERTER® (H2i®) technology, enabling reliable operation in outdoor temperatures as low as -30°C while maintaining strong heating capacity in extreme cold. With a coefficient of performance (COP) of up to 5.05, the system delivers exceptional energy efficiency, helping reduce energy consumption and carbon emissions without compromising comfort across a wide range of residential and commercial applications.

At the heart of the system is a fully integrated hydrobox, combining key hydronic accessories, including a circulation pump, expansion vessel, magnetic filter, booster heater, and plate heat exchanger, into a compact, service-friendly unit. The system distributes heated or chilled water throughout the building, making it well suited for both new construction and hydronic retrofit applications.

The Ecodan WUZ offers a wide range of performance capabilities, including:

• Year-round hot water production with heating supply water temperatures up to 70°C (LWT), ensuring strong performance and compatibility with existing heat emitters
• Space heating and cooling capability for all-season comfort
• An advanced Eco Mode that automatically adjusts water temperature based on outdoor conditions to optimize efficiency without user intervention
• Available capacities of 2, 3, and 4 tons (24,000 to 48,000 Btu/h)

The system is engineered with low-GWP R-32 refrigerant, supporting sustainability goals while maintaining high performance.

Additional features include:

• Quiet operation as low as 41 to 45 dB(A) with anti-vibration design
• Integrated or external zoning capability for customized comfort
• Boiler integration for hybrid system flexibility
• Advanced system protections, including automatic air venting and flow monitoring
• Compatibility with Mitsubishi Electric’s i-Life2 Slim hydronic fan coil units for efficient, space-saving zoned heating and cooling
• Comprehensive warranty coverage of up to 12 years parts and labour through qualified dealer programs

“Historically, the residential hydronics industry has not fully realized the efficiencies and environmental benefits that heat pump technology has brought to other market segments,” said Tyler Pullen, Applied Product Manager at Mitsubishi Electric Sales Canada. “With air-to-water heat pump adoption gaining momentum in Canada, the Ecodan WUZ reflects our ongoing commitment to expanding our air-to-water and hydronics portfolio. The addition of comprehensive warranty coverage further demonstrates our commitment to supporting dealers and homeowners with long-term confidence in their investment.”
