Frequently Asked Questions

A condensing gas boiler is a high-efficiency heating system that captures and reuses heat from exhaust gases that would otherwise be lost in traditional boilers. By condensing water vapor in the flue gas, it recovers latent heat, achieving thermal efficiencies of 108-109% (based on lower heating value). This results in significant energy savings and reduced carbon emissions.

The TBLN Series covers 60-2800kW, designed for medium commercial buildings, schools, and residential complexes up to 46,600m². The TBYG Series covers 3500-7000kW, suitable for large industrial plants, commercial complexes, and district heating systems up to 116,000m². Both series feature max 108% efficiency and 30-year design life.

In boiler engineering, efficiency is calculated based on the lower heating value (LHV) of the fuel. Values above 100% are possible because condensing technology recovers the latent heat of water vapor in exhaust gases — energy that is completely lost in conventional boilers. This represents actual fuel savings of 15-20% compared to non-condensing boilers.

Certainly. We support custom power, structure and accessories according to project requirements for residential and industrial use.

Yes. All Belitto condensing gas boilers use internationally certified components from leading European suppliers including Bekaert (Netherlands), Dungs (Germany), EBM (Germany), Siemens (Italy), and SIT (Italy). The complete boiler systems meet international safety and performance standards including CE certification.

All TBLN and TBYG Series condensing gas boilers feature a 30-year design lifetime — approximately twice the lifespan of conventional boilers. This provides superior total cost of ownership (TCO) for long-term projects. The 1-year warranty includes full machine coverage with tracking service.

Our condensing gas boilers are primarily designed for natural gas. They can also be configured for LPG (liquefied petroleum gas) with appropriate adjustments. Please contact our technical team to discuss your specific gas supply specifications.

Condensing gas boilers require annual inspection and maintenance, including heat exchanger cleaning, burner inspection, gas valve calibration, and condensate trap cleaning. Our recommended maintenance schedule ensures optimal efficiency and extends equipment life. We provide detailed maintenance documentation and remote support.

Yes. Our boilers support GPRS remote monitoring via WeChat or dedicated mobile APP. You can check real-time operating parameters, adjust temperature settings, and receive fault alerts from anywhere. This feature significantly reduces on-site maintenance requirements.

Standard delivery time is 4-8 weeks depending on model and configuration. For urgent projects, we offer expedited production options. International shipping time varies by destination. Contact our sales team for a specific delivery estimate for your location.

We provide comprehensive installation guidance including detailed manuals, piping diagrams, and electrical schematics. Our technical team is available for remote installation support. For large projects, we can arrange on-site commissioning assistance by our engineers.
