Works As Advertised.

  • I bought this for our powder room. I wanted something small, so I could "hide" it under our pedestal sink. This little heater did the trick. It's obviously still noticeable because of our sink type, but the heater is small enough that you don't notice it from the hall or when you're standing over the sink. It's also nice that it runs off of a standard 120V outlet. I may install more of these, if I can find a way to route power under our other sinks.
