I’ve bled the radiators and the boiler’s in good shape. Maybe replace the thermostat or look at wiring. Everything there is in good shape and otherwise kosher.

OK, so this is weird, but wondering if anyone’s had similar experience?

Whenever my heat goes on, the thermostat seems to omit a low hum – but in only certain locations. Most prevalent being my top floor bedroom, which is directly above the thermostat on the parlor floor. You can’t actually hear the noise while you’re standing near the thermostat.

Hum is akin to the noise neon lights make. When the thermostat “clicks off” the humming goes away instantly.

Probably poltergeists, but aside from that, any ideas?

Thanks, Johnny

  1. A thermostat is essentially a relay that is operated by a thermometer and a timer. The noise you are hearing is the coil. If it is audible it is most likely failing. Time for a new thermostat – it sounds like yours is not long for this earth.

  2. My ability to copy and paste is not what it was . . .
