ZN Air to Water Heat Pump: Efficient Home & Business HVAC

Air-to-Water Heat Pumps

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.

Industry-Leading Components for Enduring Quality

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.
Swimming Pool Heating Systems: Circulates pool water through a heat exchanger warmed by the heat pump.
Spa Heating Systems: Specifically designed to heat water for hot tubs and spas.

FAQ

What temperature do air source heat pumps work at?

They can be effective down to temperatures as low as -25°C and typically heat water up to 55°C, with newer models reaching max 75°C

How do I know if a heat pump suits my property or project?

Our team provides site assessments analyzing insulation, distribution systems, and operational requirements to deliver detailed ROI projections based on your facility profile and utility rates.

What are the cost considerations for installing an air source heat pump?

Commercial systems deliver 30-50% operational savings with typical payback within 3-7 years. Volume pricing and financing options preserve capital, while tax incentives accelerate ROI for multi-location implementations.

Can ZN heat pumps provide hot water?

Absolutely—models like our R290 Heat Pump reach up to 75°C, compatible with specialist cylinders for efficient hot water supply.
