Gas-Fired Heating & Hot Water Boiler Comprehensive Performance Test Bench

Customer Background

The customer in this case is a manufacturer specializing in the R&D and production of gas-fired combi boilers and household gas water heaters. Their products are mainly supplied to both domestic and international markets, covering product certification testing, energy efficiency evaluation, and mass production quality inspection.

As the product portfolio expanded, the customer established a more complete laboratory testing system covering R&D verification, type testing, and production quality control. This created higher requirements for test equipment integration, standardization, and long-term stability.

Customer Challenges

Before adopting our solution, the customer faced several key challenges in boiler performance testing:

1. Fragmented Multi-Standard Testing Systems

The original testing setup was separated into multiple independent systems for:

GB 6932-2015 gas water heater testing

GB 25034-2020 combi boiler testing

GB 20665-2015 energy efficiency testing

This resulted in fragmented workflows and inconsistent data management.

2. Low Efficiency in Test Condition Switching

Testing different product models required frequent adjustments of:

Gas pressure conditions

Water flow rates

Thermal load settings

The previous system required manual and scattered adjustments, leading to slow transitions between test conditions.

3. Limited Stability and Repeatability

During long-term continuous testing, the existing equipment showed:

Flow fluctuations

Temperature deviations

Insufficient data repeatability

This affected the reliability of type testing and certification results.

4. Complex Maintenance and High Downtime

The previous system had a dispersed pipeline structure, which caused:

Time-consuming disassembly for maintenance

Difficult troubleshooting

Increased laboratory downtime

Our Solution

To address these challenges, we provided a Gas-Fired Heating & Hot Water Boiler Comprehensive Performance Test Bench, designed as an integrated, modular, and standards-compliant testing platform.

1. Integrated Multi-Standard Testing Platform

The system fully complies with the following standards:

GB 6932-2015 Household Gas Instantaneous Water Heaters

GB 25034-2020 Gas-Fired Heating and Hot Water Combi Boilers

GB 20665-2015 Energy Efficiency Grades for Gas Appliances

This enables a single platform to support multiple testing requirements, eliminating redundant equipment investment.

2. High-Precision Integrated Control System

The system features centralized control of gas and water circuits, enabling:

Accurate gas pressure regulation

Stable water flow control

Fast switching between multiple test conditions

This significantly improves testing efficiency and reduces operator error.

3. Industrial-Grade Structural Design

The equipment is built with:

Aluminum alloy frame structure

Fully enclosed 201 stainless steel cabinet

Explosion-proof, waterproof, and corrosion-resistant design

Ensuring stable performance in long-term laboratory operation environments.

4. Modular Maintenance Architecture

Key components are designed in modular units:

Independent gas pipeline modules

Separate water circuit modules

Segmented instrumentation systems

This allows localized maintenance without shutting down the entire system, significantly reducing downtime.

Project Results

After commissioning, the customer achieved significant improvements in their laboratory testing operations:

Unified multi-standard testing platform management

Improved efficiency in test condition switching

Enhanced data consistency and repeatability

Overall improvement in laboratory productivity

The system has become a core testing platform for both product development and certification processes.

Customer Feedback

After installation and operational use, the customer provided positive feedback:

“The integrated testing system effectively solved our fragmented multi-standard testing issues. Test condition switching is now much faster, and data stability has significantly improved. Especially in long-term continuous testing, the system demonstrates excellent reliability, greatly reducing laboratory maintenance workload.”
