I have an old electric space heater I got at True Value hardware in Aspen Colorado around 1983. I has kept me and several cats warm for almost 30 years. There are no circuit boards in it, no computer chips, no remote controls to adjust all the settings from my recliner but it works. Mj makes fun of it and every now and then we decide it is time to retire it. In the past few years I have bought several new computerized heaters to replace it. The last one was nice. It had a remote control. I could set the temp I wanted it to maintain but it didn’t last. When I got the last one, a Lasko made in Japan, I put the old one under the house just in case. Just in case came a few weeks ago and out came old true and tried. This morning the heater decided not to work. I took it apart as all the switches and controls are mechanical and if one quits I can take it apart and clean the mechanical contacts and it works again. One of the wires on the cord at the plug for the wall had come loose. Tighten a screw and we are back in business. I guess I am still an analog guy in a digital world at times.
