Excess dust

Trash and dust accumulate in your water heater. The dust particles in the house come from the air. Whenever you switch on your hot water system after a lengthy period, dust and debris burn, emitting an odd odour.

Burning insulationburning insulation

The scent of burning rubber or plastic is every day when insulation is burned. This might happen as a result of improperly placed insulation or outdated insulation.

Water heaters usually have a packed insulation coating on the outside to keep it from getting too hot to hold. This insulation, however, should never come into direct contact with flames. If the insulation is exposed to fire, this will burn and emit a burning rubber or plastic odour.

Examine your heater to see if it’s the source of the odor of burning plastic or rubber. If that’s the case, remove your water heater’s base cover to inspect the burner section.

Corroded Anode Rod
