Frequently Asked Questions
- What is the difference between a hot water boiler and a steam boiler?
- A hot water boiler heats water below the boiling point to feed a network of radiators or radiant floor systems. A steam boiler produces pressurized steam, used for heating or industrial processes. Maintenance and safety requirements differ significantly.
- What are the signs that a boiler needs repair?
- Decreased efficiency, rising gas consumption, unusual noises, water leaks, unstable or yellow flame, recurring error codes, and difficulty maintaining the set temperature are common indicators.
- How long does a commercial boiler last?
- A well-maintained commercial boiler has a typical lifespan of 20 to 30 years. A regular preventive maintenance program and proper water treatment are the key factors in longevity.
