Homes in Kenwood often rely on radiant floors, radiators, radiant panels, or hydronic furnaces for heat. Behind every radiant system is a boiler that must be sized correctly and maintained properly. Many Kenwood homes still use cast iron boilers or copper boilers that lose efficiency over time. Most homeowners upgrade to high efficiency boilers or condensing boilers for better radiant output and lower utility bills. Our installation process includes clear estimates, fast turnaround, and system recommendations tailored to your homeβs radiant layout. We also install radiant manifolds, indirect water heaters, and indirect tanks to improve heating performance and hot water reliability.
Our hydronic boiler service trucks carry pumps, valves, sensors, controls, radiant manifold components, cast iron boiler repair parts, copper boiler fittings, indirect tank parts, and condensing boiler components. Most repairs are completed in one visit. If a specialty part is needed, our warehouse team sources it immediately to get your heat restored quickly.
Every boiler needs annual maintenance including cast iron boilers, copper boilers, high efficiency boilers, and condensing boilers. Routine maintenance ensures your radiant floors, radiant panels, radiators, and hydronic furnaces run safely and efficiently. Annual boiler maintenance includes: - System flushing - Combustion testing and cleaning - Sensor and control checks - Safety inspection - Radiant manifold balancing - Indirect water heater inspection These steps protect your warranty, reduce heating costs, and extend the lifespan of your radiant system.
