Building the foundation modern Heating 4.0
The Luoyang Xiyuan Jiadi residential estate, equipped with Diehl Metering products, comprises 1,373 households. Before the smart heating solution, the heating network lacked the granular data needed for precise regulation. The transition from quarterly meter readings to hourly consumption data has fundamentally transformed network management.
To date, Luoyang has implemented unmanned operation at 713 heating stations, reducing the workforce by over 2,000 people and cutting overall energy consumption by 25.8%, resulting in significant energy savings. Within this system, accurate and reliable metering data forms the cornerstone for achieving energy-saving optimization and enabling self-management by users.
Anomalies are detected earlier. Leaks and inefficiencies within the distribution network and on the customer, side are identified faster. Field interventions are prioritized based on data-driven visibility of network performance, enabling a shift from reactive maintenance to proactive optimization. Integration combined with platform integration and demand-based regulation, has provided a valuable model for the industry.

Closing the Loop: From quarterly redeadings to real-time, on-demand control
Together with Diehl Metering, Luoyang implemented a connected ecosystem for remote meter reading and intelligent heating control. All meters were equipped with radio technology, and data is transmitted through a robust fixed network architecture, ensuring continuous coverage across the entire project area.
Central to this solution is the Precision Heating Integrated Platform, which manages all consumption and temperature data. The system performs load forecasting and precise regulation based on real-time data. Users can independently adjust their heating via the 'Luore Heating Manager' app, achieving 'heating on demand, warmth at your fingertips.'
As Luoyang's first smart heating station compliant with the Heating 4.0 standard, this facility has achieved fully automated, intelligent operation across the entire system. One of its core pillars is an efficient control system based on precise metering and data integration, serving as the technological cornerstone for the project's success.

Earlier anomaly detection, lower energy consumption and greater transparency for users
With the new system in place, Luoyang has implemented unmanned operations at 713 heating stations, reducing the workforce by over 2,000 people. Most importantly, accurate metering and data integration have enabled total energy savings of 1.67 million GJ during the 2024–2025 heating season, saving users over 65 million yuan in heating costs.
The digital transformation also benefits end customers directly. Through the mobile app, residents gain convenient access to control their heating, receive transparency in billing, and can adjust their consumption based on real-time needs.
Diehl Metering's high-precision metering hardware and stable data integration solutions are the technological cornerstone for our achievement of unmanned operation at 713 heating stations and a 25.8% reduction in overall energy consumption. The company is a core strategic partner that has helped Luoyang transition from traditional heating to Smart Heating 4.0, creating a win-win situation for all parties involved.
