Boiler Installation
If your home uses radiant floors, radiators, radiant panels, or a hydronic furnace, the boiler behind it needs to be reliable. Many older homes in San Rafael still depend on cast iron boilers or copper boilers that lose efficiency over time. Homeowners often upgrade to condensing boilers or high efficiency boilers to deliver steady radiant heat and reduce energy bills. Our installation process includes clear estimates, fast installation, and customized recommendations based on your home’s radiant heating system. We also install radiant manifolds and indirect water heaters or indirect tanks to improve heat delivery and hot water supply.

Our hydronic boiler trucks carry pumps, valves, sensors, controls, radiant manifold parts, cast iron boiler repair kits, copper boiler fittings, indirect tank parts, and condensing boiler components. This allows us to repair radiant floors, radiators, radiant panels, and full hydronic furnace systems quickly. If a specialty boiler part is needed, our warehouse team sources it immediately.

Annual maintenance includes: - System flushing - Cleaning and combustion testing - Control and sensor checks - Radiant manifold balancing - Safety inspection - Indirect water heater inspection These steps protect your warranty and keep your radiant floors, radiant panels, radiators, and hydronic furnaces working reliably throughout winter.
