Solving Hot Water Boiler Problems

Got boiler problems? Cincinnati heating and cooling experts Thompson Electric, Plumbing, Heating &  Cooling are here to help. Hot water boilers are used in hydronic heating systems, in which hot water is distributed through a home’s pipes and delivered to rooms via a radiator or baseboards. These boilers may be powered by natural gas, fuel oil, or propane.

While boilers are generally reliable, they have more parts than a forced air furnace and may experience problems related to the water circulator pump, expansion tank, or another component. Some common boiler problems and their related causes/repairs are as follows:

Loud pipes

Possible causes: Trapped water in return lines or faulty circulator

Possible repairs: Circulator repairs requiring a service technician; adjustment of return line or radiator slope

Poor heating performance

Possible causes: Mineral deposits in heat exchanger or boiler (for gradual changes in performance) or improper water level (for sudden changes)

Possible repairs: Boiler flush; adjustment of water level and pressure

Boiler not producing heat

Possible causes: No power to boiler, thermostat malfunction, low water level, or burner malfunction

Possible repairs: Resetting of tripped circuit breaker; replacement of blown fuse; adjustment of water level and pressure; relighting of standing pilot; troubleshooting of electronic ignition system or thermostat

Water leakage around boiler

Possible Causes: Faulty pressure relief valve or circulator (pump), or leaking water pipe connection

Possible Repairs: Circulator repairs requiring a service technician; replacement of pump seal or valve; repair to leaky connection
