I have to admit
Those kinds of heaters give me the heebie jeebies. Seeing a glowing element makes me feel like my house is going to burn down or something. Kinda like how some people are deathly afraid of natural gas appliances and heating...I feel the same about certain types of resistance heating.
That heater is pretty neat though... From afar. I remember visiting someone in Forestville, CA that had not a single modern amenity in their home. Not even Internet or central heat. They cooked and heated with a wood stove in the kitchen, and fireplaces in other parts of the house. She had a 1930s hot plate in her bedroom for making tea that freaked me out when I saw it, and saw that it was being used. The house was real cool though, they had a library with all wood paneling that they got from an estate in England (long story how it ended up here), and in it they had a wooden phone booth with a connected and working rotary phone. There was other stuff too but it's been so long I can barely remember.
