Like others said, The problem is unplugging and replugging each time or use?,,if I read that right. With Each plug yank, just consider a bit more resistance to run your heater next time and the other risks that climb as well(riding the lightening, youch!,, especially if your set to run at 1500 when socketed right in. The on-off/ "Idiot" lights are very low draw as you already know. But, if you have a bunch of electronic idiot lights lit all around the house on your fancy uppety gadgets,,then the meter hums a bit fast. All bets are off at Christmas time for your power bill. My Meter is trying to reverse Earth's rotation right now,,lol.
40,000 twinkle/Idiot? lights.
Yep, Tip-Over and also Over-heat safety's please. Some of the older Titan heaters don't have that Over-heat,,and they sold millions of those to us. Buyer beware on a old electric heater.
