ZN Air-to-Water Heat Pumps are all-in-one hydronic heat pumps for cooling, heating, and hot water. Our DC inverter technology makes them highly energy-efficient, and EVI technology ensures stable cold climate operation. They're efficient, eco-friendly, and perfect for residential and commercial use.
ZN - Reliable Air Source Heat Pump Manufacturer in China
Air source heat pumps act like a “heat mover,” utilizing the physical properties of a refrigerant. Through a refrigeration cycle and compression process, they absorb heat at low temperatures and release it at high temperatures.
Simply put, they extract heat from the outdoor air and transfer it to a building’s water system (such as underfloor heating, radiators, or water tanks). Of course, in the summer, this process can be reversed to transfer heat from indoors to outdoors, achieving a cooling effect.
ZN is a heat pump manufacturer and supplier from China, established in 2008 with technical roots from Hualing Group and Mitsubishi Electric. We offer a diverse range of heat pump products, including heating and cooling, hot water, swimming pool, heat pump dryers etc.

Smart Power for Perfect Comfort & Savings
Traditional air to water heat pumps are either fully ON or OFF, wasting energy by running at full power even when you need just a little heat—like a car constantly starting and stopping.
All ZN air to water heat pumps are equipped with a DC inverter compressor and an advanced control system. These intelligently adjust power output from 20% to 100% to precisely match your home’s heating and cooling demands.
This ensures smooth, quiet operation, maintains water temperature stability within ±0.5°C, and delivers significant energy savings, keeping your home consistently cozy and comfortable.
Componentes líderes da indústria para uma qualidade duradoura
All ZN air to water heat pumps feature key components from industry-leading suppliers. For instance, we use DC inverter compressors from Panasonic and Mitsubishi, and plate heat exchangers from Swep, ensuring both high quality and long service life.
ZN Air to Water Heat Pumps Built for Reliability
ZN air to water heat pumps feature advanced, multiple safety technologies for reliable operation. These include compressor high-pressure, low-pressure, and overload protection, plus anti-freeze and automatic winter anti-freeze systems.
Additional safeguards—such as differential pressure flow switch, temperature difference flow, fault protection for temperature sensors, and high-temperature exhaust protection—work alongside other automatic features to minimize downtime and ensure consistent performance.

What hydronic systems work with an Air to Water Heat Pump？
Air source heat pumps can connect to various systems within a building to deliver heating or cooling. These common “terminals” or end-use distribution systems include:
- Underfloor Heating (Radiant Floor Heating): Circulates heated water through pipes embedded in the floor for comfortable, even warmth.
- Radiators: Standard heating units that circulate heated water to warm rooms.
- Hot Water Tanks (for Domestic Hot Water): Stores hot water for household use (e.g., showers, sinks), heated efficiently by the heat pump.
- Fan Coils (Fan Convectors): Units that use a fan to blow air over a coil containing heated or cooled water, quickly distributing conditioned air.
- Central Ducted Systems (via Hydronic Air Handlers): Heated or chilled water from the heat pump can be sent to a specialized air handler unit, which then distributes conditioned air through a central duct network.
- Sistemas de aquecimento de piscinas: Faz circular a água da piscina através de um permutador de calor aquecido pela bomba de calor.
- Sistemas de aquecimento de spas: Especificamente concebido para aquecer água para banheiras de hidromassagem e spas.
Podem ser eficazes até temperaturas tão baixas como -25°C e, normalmente, aquecem a água até 55°C, com os modelos mais recentes a atingirem um máximo de 75°C
A nossa equipa fornece avaliações do local, analisando o isolamento, os sistemas de distribuição e os requisitos operacionais para fornecer projecções detalhadas do ROI com base no perfil da sua instalação e nas taxas de serviços públicos.
Os sistemas comerciais proporcionam poupanças operacionais de 30-50% com um retorno do investimento típico de 3-7 anos. O preço por volume e as opções de financiamento preservam o capital, enquanto os incentivos fiscais aceleram o ROI para implementações em vários locais.
Modelos absolutos como a nossa bomba de calor R290 atingem até 75°C, compatíveis com cilindros especializados para um abastecimento eficiente de água quente.
O tamanho varia consoante o tipo de edifício e o clima - 6-40 kW para casas, até 250 kW para espaços comerciais. Contacte-nos para uma consulta de dimensionamento profissional.
