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.
