Boiler Services

Hot water or steam heating systems for radiant warmth.

Boilers heat water (or produce steam) to provide radiant heat through radiators, baseboard heaters, or radiant floor systems. This technology provides comfortable, even heat without the air movement of forced-air systems. Many older Bay Area homes have boiler systems, and some new homes incorporate radiant floor heating. Boiler heating feels different from forced air and is preferred by many homeowners.

How Boilers Work

Boilers heat water using gas, oil, or electricity. Hot water circulates through pipes to radiators, baseboards, or radiant floor tubing where it releases heat. Cooled water returns to the boiler for reheating. Circulator pumps move water through the system. Zone valves or multiple circulators can create heating zones.

Common Boiler Issues We Repair

Boiler Maintenance Tips

Schedule annual professional maintenance
Check pressure gauge regularly
Bleed radiators when cold spots appear
Monitor for leaks around system
Test pressure relief valve annually
Keep boiler room clean and clear

Efficiency Information

Modern condensing boilers achieve 90-98% efficiency. Older boilers may be 80% or less. Radiant floor systems provide even heat efficiently at lower temperatures. Hydronic heating avoids duct losses. Bay Area mild winters mean moderate heating costs regardless of system type.

Expected Lifespan

Boilers typically last 15-30 years, often longer than forced-air systems due to fewer moving parts. Cast iron boilers may last 40+ years with care. Annual maintenance extends life and catches problems early.

Bay Area Considerations

Many San Francisco Victorians and older Bay Area homes have boiler heating. Radiant warmth is appreciated in the foggy climate. Newer homes sometimes incorporate radiant floor heating. Boiler systems can be efficient but require specialized service. Not all HVAC companies service boilers.

Boiler FAQ

How often should my boiler be serviced?

Annual maintenance is recommended, typically before the primary use season. Cooling equipment in spring, heating equipment in fall.

What is the typical lifespan of a boiler?

Boilers typically last 15-30 years, often longer than forced-air systems due to fewer moving parts. Cast iron boilers may last 40+ years with care. Annual maintenance extends life and catches problems early.

How do I know if my boiler needs repair?

Your boiler may need attention when: Radiators or zones not heating. Unusual noises from boiler or pipes. Pressure gauge outside normal range.
