Troubleshooting Hydronic Fan Convectors
Check the room thermostat first and then the boiler to determine if either is malfunctioning (see Table 2-4). Procedures for troubleshooting boilers, water heaters, and thermostats are detailed in the appropriate chapters of Volumes 1 and 2.
Note
The boiler or dedicated water heater should be set at a minimum temperature of 140ºF for the fan convector to operate efficiently.
Check the manufacturer’s installation instructions to make certain the convector is properly piped (correct sizing, layout, and so on). If the flow rate for the convector is less than 1 gpm, then there is a piping problem.
Check the wiring to make sure the convector is wired properly, and then examine the wires for loose connections or damaged wiring. If the wiring, piping, and boiler (or water heater) check out all right, the problem is in the convector itself.
