Anyone who’s ever played with light dimmers knows that dimmer buzz well.  The light, as well as the dimmer, can buzz loudly when the dimmer is set lower than the brightest setting.

Check the screws that hold the heater to the wall as well. For these spaces, try we portable, no-fan hydronic heaters. This makes a more solid backing for moving and heating components.  This deadens vibration and lowers hum transmission. I primed the pump and re-connected the wires properly, but the furnace does not fire now. There are 2 fireplaces and it seems like the noise vibrates out from them. After a few seconds of buzzing, the red button will trip. Plus, they run with cooler element temperatures while heating.

A tapping – or gurgling sound like the one described above – could also be caused by a build-up of limescale within the pipes and radiators. Just guessing as of course by mere e-text we're missing more clues. Cad cell control or stack relay buzzing or jamming trouble: if you hear or have ever heard buzzing from any heating system control that includes a relay switch, watch out for a control cover that is in contact with a relay switch in the unit.
