The heat being emitted by ABIS Clothes airers are just warm and even safe to touch. If your clothes suddenly end up having burned in them, you might have left your clothes on the clothes airer for too long, or the emitted heat is above the average temperature. If the latter is the reason, there might be an electrical issue, whether with the motor or the rods, that causes emittance of higher temperature. It would be best to consult with an electrician to fix the problem.
