The Combi Boiler Test Rig (Model WH-CR-Lab) is a laboratory type-testing station for gas-fired combi and wall-hung boilers. Where the production wall-hung boiler bench is configured for fast final QC, the WH-CR-Lab is built for R&D and certification: multi-channel action and tightness testing, detailed combustion and safety measurements, and precise data capture that engineers use to validate a new boiler design and compile certification files.
It is the station behind searches for a combi boiler test rig or combi boiler testing equipment for laboratory and notified-body work, and it is paired with the thermal efficiency test system for efficiency determination.
What the Rig Tests
- Valve & control action — multi-channel operation of gas and water controls.
- Gas tightness — precision leak testing; see gas tightness & flame failure testing.
- Combustion & efficiency — heat input, useful output and thermal efficiency; see thermal efficiency & CO testing.
- Heating & DHW performance — both operating modes under load.
- Safety protection — flame failure, overheat and pressure safety functions.
Standards & Compliance
The rig is configured for type testing to EN 15502 and EN 297, supported by the EN 15502 boiler standard guide and wall-hung boiler certification testing; electrical/gas safety follows IEC 60335-2-102. The complete item list appears in key test items for wall-hung boilers. Wanhe provides the measurement and documentation support summarized on certifications.
Type-Testing Workflow
- Install the boiler on the lab frame and connect gas, water, heating loop and flue-gas analysis.
- Define the test matrix (rated, boundary, safety and efficiency points) in the control software.
- The rig runs multi-channel tests, logging high-resolution data at each point.
- Engineers export the dataset for certification files and design validation.
Key Features
- Laboratory-grade multi-channel action and tightness testing.
- High-resolution data capture for type testing and R&D.
- Configurable to EN 15502, EN 297 and IEC 60335-2-102.
- Pairs with the thermal efficiency test system for efficiency determination.
- OEM/ODM custom frame and sensor configuration.
Type Testing vs. Production QC
| Aspect | Test rig (this page) | Production bench |
|---|
| Primary purpose | Certification & R&D type testing | Final QC of every unit |
| Data capture | Continuous logging across the full range | Fixed pass/fail sequence |
| Output | Traceable type-test report | Per-serial-number report |
| Reference | EN 297 / EN 15502 | EN 15502 / GB 25034 |
Integrated Measurement Train
The rig combines a gas meter, water flow meters, temperature and pressure sensors and a flue-gas analyser with a data-acquisition system, so efficiency and performance are calculated from synchronised measurements rather than manual readings. For efficiency-focused work it is used together with the thermal efficiency test system, which provides the heat-input/output and flue-gas analysis modules.
Standards & Documentation
Test methods follow EN 297 and EN 15502 for gas-fired boilers and EN 625 for combi boiler hot-water performance, with GB 25034 available for the Chinese market. The standards and the available document set are listed on our certifications page, and a real laboratory installation is shown in the EU wall-hung boiler lab bench case study.
Why Choose the Wanhe Rig
| What you need | How the rig delivers |
|---|
| EN 297 / EN 15502 type-test data | Pre-configured test items and continuous logging |
| Defensible certification records | Synchronised, traceable, exportable measurements |
| Coverage of heating and DHW | One station for both functions of a combi boiler |
| Custom laboratory layout | Sensors, gas type (LPG/NG) and ranges configured to your models |
Applications
- Boiler manufacturers’ R&D labs — new-model validation and design iteration.
- Certification laboratories — type testing with traceable, high-resolution data.
- Heating-appliance groups — independent verification of supplier designs.
A laboratory installation is documented in the EU wall-hung boiler lab bench case; for production QC rather than type testing, see the wall-hung boiler test bench.

Frequently Asked Questions
Is this for production or laboratory use?
The WH-CR-Lab is a laboratory type-testing rig for R&D and certification. Production final QC uses the WH-BG02 wall-hung boiler bench.
Can it measure thermal efficiency to EN 297/EN 15502?
Yes, and it is commonly paired with the thermal efficiency test system and flue-gas analysis for the efficiency calculation.
Can the rig be customised to our boiler range?
Yes. Frames, sensors and gas/water circuits are custom-engineered; see custom lead time.
