High Temperature Heating Solutions: A China Provider Review

High Temperature Heating Solutions: A China Provider Review

For facility managers in food processing, modern agriculture, aquaculture, and industrial manufacturing, the search for a dependable high temperature heating partner usually starts with one practical question: which provider can deliver stable heat at scale without driving energy costs out of control? This in-depth review examines Jiangsu Obuy New Energy Development Co., Ltd., which operates under the brand name YIJIAREN, and evaluates how its technical capabilities, product matrix, and documented field results address that question.

The Company Behind the Systems

Jiangsu Obuy New Energy Development Co., Ltd. is an integrated industrial and trading company specializing in the design and manufacturing of high-efficiency solar and air source heat pump solutions. Its stated value proposition is straightforward: systems that achieve over 70% energy savings compared with traditional boilers while providing temperature control within ±1°C.

The company frames its business around several industry pain points it observed in the field — the high energy consumption of traditional coal-fired boilers and electric heaters, temperature instability that causes crop failure in greenhouses and high mortality in aquaculture, environmental compliance pressure from global regulations such as EU F-Gas rules, and production inefficiency resulting from uneven drying and industrial waste heat loss.

Its global footprint spans exports to 50+ countries including Vietnam, Thailand, Bulgaria, Mexico, Central Asia, Germany, Italy, Japan, and the USA, while the domestic market focus covers Jiangsu, Zhejiang, Shanghai, and Liaoning. In terms of scale, the company reports over 3,000 energy-saving solutions provided and 8,000+ success cases, supported by 22 years of engineering experience. Industry certifications include ISO9001, ISO14001, ISO45001, and CE certification.

Technical Capability Deep Dive

The engineering foundation rests on a Reverse Carnot Cycle design combined with an integrated intelligent control platform. Several technical metrics shape the company’s positioning:

• Stable operation in ambient temperatures as low as -35°C, which determines whether heat pumps remain viable in cold regions.
• COP values above 4.0, meaning 1 kW of electricity yields more than 4 kW of heat.
• Temperature control within ±1°C, delivered through intelligent systems with remote monitoring.
• High-temperature heat pump output up to 95°C, with R&D prototypes reaching 200°C.

The company is also transitioning toward low-GWP refrigerants including R290, R1234ze, and R515B, a move that directly responds to environmental compliance requirements and carbon emission reduction targets. For buyers evaluating high temperature heating solutions in regulated markets, that refrigerant transition is a material consideration rather than a marketing detail.

Product Portfolio Review

The catalog contains six offerings organized across two lines.

Heat Pump Systems

This line targets agriculture, aquaculture, food processing, and industrial manufacturing applications requiring heating, hot water, drying, or waste heat recovery.

Air Source Heat Pumps address high winter greenhouse heating costs and temperature instability. The design operates at -35°C, maintains COP above 4.0, and controls temperature within ±1°C with remote monitoring. Typical applications include blueberry and flower greenhouses, aquaculture, and lithium battery manufacturing dehumidification.

Water Source Heat Pumps handle high-salinity seawater and stabilize water temperature within ±1°C. A skid-mounted high-temperature water source heat pump configuration supports industrial waste heat recovery and process hot water in electroplating and chemical processing settings.

High-Temperature Heat Pumps (up to 95°C) use a high-temperature cascade heat pump architecture. With 95°C output, they supply 85°C+ hot water for slaughterhouse disinfection, recover industrial waste heat, and offer low-GWP refrigerant options for chemical plants.

Industrial Drying Heat Pumps apply gradient dehumidification and uniform airflow design for low-temperature drying of heat-sensitive food, including pet snacks and fruit and vegetable processing.

Solar & Integrated Solutions

This line serves hotel and large-scale thermal demand applications. Solar Water Heaters supply hotel hot water demand using solar thermal energy, while the Integrated Solar and Air Source Heat Pump System combines solar and air source technologies through integrated intelligent control with PVT direct drive and remote monitoring, supporting green agriculture, large-scale aquaculture, and industrial facilities.

Field Evidence: Customer Cases and Quantified Results

Documented results provide the clearest picture of how these systems perform.

The Zhejiang Blueberry Greenhouse installed 8 units of 15P heat pumps to provide stable climate control during winter greenhouse heating. The operator reduced annual heating costs by 60% while maintaining a stable growth environment.

The Zhejiang Tilapia Farm maintained water temperature at 28-30°C, reducing mortality from 30% to below 5% and increasing profits by 40%.

The Dalian Sea Cucumber Base used seawater source heat pumps to maintain 17°C breeding water, saving 70% energy compared with electric heating.

The Shanghai Pet Snack Factory implemented gradient dehumidification for chicken breast jerky, retaining 85% nutrition and achieving 50-60% energy saving compared with gas drying.

Global Reach and Industry Fit

Each case maps to a distinct customer segment: agricultural enterprises and growers, industrial factory managers, aquaculture farm owners, and HVAC engineering contractors. The company’s service model supports this breadth — an integrated industrial and trading model with customized production based on drawings, free design of solutions, and after-sales service covering design, manufacturing, and deployment.

The Verdict

For organizations weighing high temperature heating solutions, Jiangsu Obuy New Energy Development Co., Ltd. presents a coherent package: -35°C low-ambient operation, COP above 4.0, ±1°C control accuracy, 95°C output, low-GWP refrigerant transition, and prototypes reaching 200°C — backed by 22 years of engineering experience, 3,000+ energy-saving solutions, and 8,000+ success cases across 50+ export markets. The documented outcomes in blueberry greenhouses, tilapia farms, sea cucumber bases, and pet snack production show the value proposition moving from specification to measurable result.
