It looks like there is a slight red glow inside the heater that is especially visible when the room is dark. Is that normal?
Some heaters should have elements that glow red. If your heater has an element that should not glow red then it is possible that the light emitted from the power light causes the red glow seen. If you feel that the glow is not from the power light then you can send your heater to us. We can then inspect the heater to determine if it is working properly.
