Multi-Scene Heat Pump Solutions

Years of iteration, one reliable system. Our heat pumps deliver efficient heating and cooling for diverse applications – now available worldwide.

Residential Heating & Cooling

Villas, apartments, and self‑built homes – year‑round comfort with ultra‑low temperature capability for harsh northern climates.

Commercial Buildings

Offices, hotels, schools, hospitals – central heating/cooling with quiet operation (40 dB) that doesn’t disturb work or daily life.

Retrofit & Renovation

Replace traditional gas/oil boilers or electric heaters. Can be directly connected to existing radiators or underfloor heating – simple installation, short payback.

PV‑Coupled Systems

Integrate with photovoltaic systems to convert surplus solar energy into heat, maximizing self‑consumption and further reducing operational costs.

Energy & Cost Savings

R32 Commercial Series Heat Pumps achieve a COP of 3.5–4.5 under standard conditions, generating 3.5–4.5 kWh of heat per 1 kWh of electricity consumed and cutting annual energy costs by up to 75% versus electric heating and fuel boilers. Equipped with smart control and time-of-use tariff management, they only cost €110 annually for ordinary European residences, saving 39% on gas boilers and 50% on regular heat pumps, demonstrating that high efficiency combined with intelligent energy management creates sustained practical savings.
