Last year, I picked up an old Arvin Space Heater at a flea market. I've always liked these old heaters. They remind me of a cross between a tombstone radio and a medieval jousting helmet. Very art deco design with the ridges and stepped sides.
This one was marked "Don't Work" on top and I got it for $5, I think.
When I got her home I plugged her in. Her problem wasn't that she didn't work. She worked too well, truth be told. When plugged in the heater and fan ran continuously. Only way to shut it off was to unplug it. I took the unit apart, cleaned out all the dust bunnies, replaced the crunchy/brittle cloth wiring and cord, and wired in a new switch.
Problem solved :)
Here she is after I cleaned her up and gave her a new coat of paint. I decided to go two-tone, because her design was crying out for that. I don't have much use for a heater, but a fan is always welcome here in Texas. I disconnected the heater array so that just the fan runs when turned on. If I ever decide to use it as a heater all I have to do is jump two wires inside to reconnect the heater coils.
