Explore our leading commercial, residential, and industrial-grade air source heat pump units optimized for radiant floor systems. Certified to meet stringent CE standards.
Evaluating macro-market structural changes, electrification frameworks, and the integration of low-temperature water-source and air-source technologies.
Governments worldwide are accelerating carbon-neutral infrastructure transitions. Driven by EU directives like REPowerEU and local decarbonization frameworks, industrial and commercial HVAC operators are abandoning fossil-fueled boilers in favor of high-performance hydronic floor heating powered by air-source heat pumps (ASHP). Low-temperature hydronic radiation provides unmatched thermal uniformity while optimizing COP metrics, reducing commercial energy spend by up to 45% compared to baseline resistive electric or traditional combustion frameworks.
The global transition away from hydrofluorocarbons (HFCs) under the Kigali Amendment has triggered an aggressive paradigm shift towards natural and low Global Warming Potential (GWP) alternatives. Propane (R290) and Carbon Dioxide (R744) represent the pinnacle of environmental engineering. R290 models deliver optimal efficiency in residential applications with zero ozone depletion potential, while transcritical CO2 configurations output heat levels exceeding 90°C for district-level heating and process industrial lines without electrical auxiliary elements.
How Zhejiang PeakWay Pump Co., Ltd. implements Enhanced Vapor Injection (EVI) and full DC inverter control architectures to maximize seasonal SCOP.
Standard heat pump circuits face steep capacity drops in sub-zero climates due to elevated compression ratios and low mass flow. Our industrial EVI technology bypasses a portion of intermediate refrigerant gas back into the scroll compressor shell. This stabilizes gas density, suppresses discharge temperatures, and sustains high heating capacity even when the external dry-bulb ambient drops to -25°C or lower. This guarantees consistent 35°C to 45°C output loops required by underfloor hydronic matrices.
Instead of cycling traditional fixed-speed induction motors, our full DC inverter configurations continuously adjust compressor and fan speeds to track real-time heating loads. Under fluctuating ambient conditions, the inverter drive regulates output frequency to match system demand with micro-precision. This minimizes start-stop energy spikes, stabilizes floor thermal latency, and dramatically improves the system’s Seasonal Coefficient of Performance (SCOP).
A high-performance floor heating loop requires balanced flow distribution. Our design integrates smart hydronic manifolds, variable-speed EC circulation pumps, and intelligent safety releases. By managing low-delta-T thermal cycles, our heat pumps ensure that the water flowing through cross-linked polyethylene (PEX) or raised temperature polyethylene (PE-RT) underfloor pipes stays in the optimal thermodynamic exchange zone.

Different climate zones and commercial demands require targeted thermal hydraulic engineering designs.
Replacing high-emission natural gas boiler plants in traditional properties with low-charge R290 monobloc installations. Integrating directly into low-temperature floor radiant configurations, eliminating the requirement to swap internal hydronic pipe arrays.
Centralized cascade configurations (utilizing multiple 160kw DC inverter blocks) feeding insulated primary thermal buffer storage. Allows high-precision billing of individual apartment units via smart zone-control underfloor actuators.
Managing strict interior profiles for greenhouses or distribution facilities using combined underfloor hydronic lines and constant-humidity air handling. The integration of high-COP heat pumps stabilizes ambient margins while minimizing operational expenditure.
The evolution of heat transfer systems beyond simple cycle loops into smart, dynamic utility grid assets.
Modern commercial buildings use demand-response systems to limit electricity purchases during high-tariff periods. Zhejiang PeakWay is integrating Smart Grid interfaces across our product line. With Modbus and SG Ready protocols, PeakWay units dynamically coordinate with solar PV arrays and grid management networks. The system shifts high-draw cycles to peak production windows, using the concrete mass of the underfloor heating installation as a thermal energy storage sink.
To safely handle A3 class natural refrigerants (R290) in commercial projects, our advanced monobloc systems utilize fully sealed internal refrigeration compartments, spark-free electronics, and integrated leak-sensor venting valves. These designs ensure compliance with global safety standards (such as EN378 and IEC 60335) while achieving high discharge temperatures and maintaining low operational noise footprints.
Technical guidance and installation considerations for engineers, distributors, and general contractors.
R290 (Propane) has a Global Warming Potential (GWP) of only 3, making it highly compliant with strict global F-gas regulations compared to R32 (GWP 675) and R410A (GWP 2088). R290's thermodynamic properties also allow it to achieve hot water output temperatures of 65°C to 75°C without auxiliary electric heaters, even in low ambient temperatures. This makes it an ideal option for traditional radiator retrofits and efficient domestic hot water generation.
We utilize Enhanced Vapor Injection (EVI) compressors combined with full DC inverter controllers. By injecting intermediate gas during the compression cycle, we sustain density under high compression ratios. In addition, our automated hot-gas bypass defrosting algorithm prevents ice buildup on the evaporator coil, minimizing downtime and maintaining high thermal delivery in winter weather.
With correct system engineering (including secondary plate heat exchangers, magnetic dirt separators, and glycol or anti-freeze protection loops), our commercial heat pumps feature an operational design life of 15 to 20 years. Recommended annual maintenance is straightforward, focusing on cleaning the heat exchanger fin coils, testing hydraulic system pressures, verifying glycol concentrations, and checking electrical terminal torque values.
Yes, our commercial and industrial range features native RS485 communication ports supporting the Modbus RTU protocol. This allows building managers to monitor and adjust target water curves, compressor frequencies, flow temperatures, and error diagnostics from a central BMS console, optimizing HVAC efficiency across the facility.
