Query: Sleepless in Olympia

These heaters were purchased as a replacement for baseboard heaters for space considerations. Be aware that these heaters ARE NOISY and not suitable for bedroom applications if you are a light-to-moderate sleeper. We also had them installed in the family room and they interfere with the ability to hear the television and now we are constantly cycling the volume up and down. The application in the kitchen is fine, but will be looking for a lower decibel alternative in the very near future.
