Gas Wall-Hung Boiler Test Bench (WH-BG02-815A)

The Gas Wall-Hung Boiler Test Bench (Model WH-BG02-815A) is a complete performance and safety station for gas wall-hung and combi boilers. It tests both central-heating output and domestic hot water, together with combustion conditions, water pressure and safety protection, with 0.5-class measurement. The bench is used for final QC and for certification preparation, and supports the test items described in our wall-hung boiler test-item guide.

Because wall-hung boilers combine heating and DHW functions in one unit, the bench verifies both modes and the boiler’s response under load. For laboratory type testing and certification work, the combi boiler test rig (WH-CR-Lab) adds a research-grade frame; for efficiency measurement as a standalone task, see the thermal efficiency test system.

What the Bench Tests

• Heating output — central-heating performance and rated output verification.
• Domestic hot water — DHW flow, temperature stability and comfort response.
• Combustion & thermal efficiency — efficient combustion and heat input; see thermal efficiency & CO testing.
• Water pressure — operating pressure and pressure-protection behaviour.
• Safety protection — flame failure, overheat and other safety functions.
• Gas tightness — leak testing of the gas circuit; see gas tightness testing.

Standards & Compliance

Wall-hung boilers are tested against EN 15502 (gas-fired condensing boilers) and EN 297 (gas-fired central-heating boilers); see the EN 15502 boiler standard guide and wall-hung boiler certification testing. General gas-appliance safety follows IEC 60335-2-102. Wanhe supplies the measurement records and technical files required by your notified body — see certifications.

How the Test Sequence Works

1. Connect the boiler to gas, heating circuit, water supply and flue-gas sensors.
2. Select heating-only, DHW-only or combined mode and the target standard.
3. The PLC runs output, efficiency, combustion, pressure and safety tests.
4. Results are logged against limits and exported as a pass/fail report.

Key Features

• Heating + DHW dual-mode testing on one station.
• 0.5-class measurement of pressure, flow and temperature.
• Combustion, efficiency and safety-protection verification.
• Automatic data recording and report export.
• Custom fixtures for different boiler capacities and markets.

Why Choose This Combi Boiler Test Rig

Applications & Installations

Typical users are boiler manufacturers, heating-appliance plants and certification laboratories. A research-grade configuration is shown in the EU wall-hung boiler lab bench case. For cooking-appliance lines see the gas stove test bench, and for all appliance categories the gas appliance test bench.

QC & Final Inspection Mode for Wall-Hung Boilers

For factory production lines, the wall-hung boiler quality inspection bench runs a repeatable final-inspection sequence that returns a pass/fail result for every boiler with traceable records. A standard final QC cycle covers:

• Gas-tightness (leak) test — pressurises the gas circuit and detects pressure decay to flag any leaking valve, fitting or joint before the unit ships.
• Ignition & flame stability — verifies reliable ignition and stable combustion under rated load.
• Heating output & DHW performance — checks heating output and hot-water temperature against the rated specification.
• Water pressure & safety protection — confirms pressure switches and safety devices trip at the correct thresholds.
• Visual defect logging & automatic report — operators record visual defects and the system exports a dated, traceable test report per serial number.

Type Testing & R&D Mode

For laboratories and certification work, the same rig supports continuous data logging across the full operating range, so engineers can evaluate thermal efficiency, combustion behaviour and safety margins with 0.5-class measurement accuracy. Single- or multi-station layouts are available for higher throughput, and the system accepts LPG or NG gas types.

Frequently Asked Questions

Does it test combi (heating + DHW) boilers?

Yes. The WH-BG02-815A verifies both central-heating output and domestic hot water, including mode switching and temperature stability.

What is the difference from the combi boiler test rig?

This bench is for final QC and certification preparation; the WH-CR-Lab combi boiler test rig is a laboratory type-testing station for R&D and detailed certification work.

Which standards are included?

The bench is configured to EN 15502, EN 297 and IEC 60335-2-102 for your market; see certification testing.
