Wall-hung boilers must pass a strict set of performance and safety tests before they can be certified for the European market. A professional wall-hung boiler test bench typically covers the following key items:
1. Gas Tightness Testing
Verifies that the gas circuit has no leakage under rated pressure — the first safety gate for any gas appliance.
2. Thermal Efficiency Testing
Measures heating and domestic hot water efficiency at rated input, confirming the boiler meets EN 15502 / GB 25034 efficiency classes.
3. Combustion Performance
Analyzes CO/CO2 emission, flame stability and combustion pressure to ensure clean and complete combustion.
4. Water Pressure & Safety Protection
Tests water pressure resistance, overheat protection, flame failure protection and anti-freeze functions.
5. Long-Term Aging
Multi-station aging tests verify durability over the product lifecycle.
When selecting a test bench, look for 0.5 class instrumentation, computer + PLC control with data traceability, and compliance with EN 15502. Wanhe Testing builds fully customized wall-hung boiler test benches for factories and certification laboratories worldwide.
