Why are my baseboard heaters so noisy?

These sounds are mostly due to the metal reacting to sudden changes in temperature when they are turned on after a prolonged shutdown, or when they begin to heat up when the temperature drops. Noises are caused by the expansion when starting, and the contraction when cooling, of the metal components of the baseboards.

How does a baseboard heater work?

The element may be inside a single metal pipe or a long flat ‘zig-zag’ type coil. The coil threads through thin wafers of tin, aluminum, or steel. The wafers heat quickly and provide a greater surface area to radiate heat into a room. When space is heated, the thermostat shuts the heating element off, and the baseboard cools down quickly.

Why does my baseboard heater click when I turn it on?

Baseboard clicking can have two causes. If you hear the clicking as the unit heats up or cools down, it is the metal adjusting to the temperature changes. A clicking sound that occurs only when the heater turns on or off is a switch relay. It may come from the baseboard, or from the wall-mounted thermostat.
