FAQs
1. What are the main differences between steam boilers and hot water boilers?
Steam boilers produce high-pressure steam, suitable for applications needing high temperatures. Hot water boilers generate hot water at lower pressures, ideal for heating systems.
2. How do I choose the right boiler fuel type for my needs?
Fuel choice depends on cost, availability, environmental regulations, and application requirements. Gas offers clean burning, while coal is cost-effective but generates higher emissions. Biomass is sustainable but may have variability.
3. What safety features should I look for in a Chinese-made boiler?
Safety features include pressure relief valves, flame failure safeguards, and automatic shut-off mechanisms. Check for compliance with international and Chinese safety standards.
4. What is the typical lifespan of a boiler manufactured in China?
Lifespan varies based on boiler type, usage, and maintenance. With proper maintenance, a well-designed boiler can operate efficiently for 15-20 years or more.
5. How can I ensure the quality of a boiler purchased from a Chinese manufacturer?
Verify manufacturer certifications (ASME, CE), request references, inspect manufacturing facilities if possible, and thoroughly review technical specifications and warranty details.
