ZN - Reliable Heat Pump Water Heater Manufacturer in China

Heat pump water heaters are essentially “heat movers” that leverage the physical properties of a refrigerant. Through a refrigeration cycle and compression process, they absorb heat from the ambient air at low temperatures and then release it at a higher temperature to heat your water.

Simply put, they extract heat from the outdoor (or sometimes indoor) air and transfer it directly to a water tank, providing efficient hot water for your home or business.

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 Domestic Hot Water Heat Pump, Commercial Hot Water Heat Pump, Industrial Heat Pump Water Heaters etc.

Efficient Hot Water With Competitive Cost

The EVI (Enhanced Vapor Injection) system elevates conventional heat pump cycles. By adding a flash tank and an auxiliary injection circuit, it significantly boosts the compressor’s intake and output capacity.

This means our heat pump water heaters can deliver highly efficient heating even in brutally cold temperatures (as low as -25°C or lower!), while still providing hot water up to 60°C and beyond.

As a professional heat pump water heater manufacturer, ZN leverages 15 years of deep technical expertise and continuous innovation.

This allows us to effectively reduce the production costs of EVI technology, making our products incredibly price-competitive without compromising on performance.

Industry-Leading Components for Enduring Quality

All ZN air source heat pump water heaters 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.

FAQ

How do hot water heat pumps work?

Hot water heat pumps work by using a refrigeration cycle to extract heat from the air and transfer it to water. This process involves a refrigerant that passes through an evaporator, compressor, and condenser to heat the water efficiently

What are the benefits of using a hot water heat pump?

The benefits include significant energy savings (up to 70% less electricity), reduced greenhouse gas emissions, and longer system lifespan compared to traditional water heaters

Can hot water heat pumps be used in cold climates?

Yes, they can be used in cold climates, though they may require additional components like electric booster elements or defrost cycles to maintain efficiency

What temperatures and uses do heat pump water heaters offer?

They provide water below 60°C for homes, pools, and farming, 60-85°C for drying crops and preheating, and 85-120°C for industrial production and energy recovery.

What are some government incentives for installing hot water heat pumps?

Many governments offer rebates and incentives to encourage the adoption of energy-efficient technologies like heat pumps. For example, Australia provides rebates for hot water heat pump installations
