Query: My favorite heater

I've used oil-filled heaters for years, and the DeLonghi is my favorite. It's completely silent when operating, which makes it ideal for the bedroom. I usually use just the low setting, and the heater keeps the room warm without ever getting very hot to the touch. And of course the low setting is lower wattage, so I don't worry too much about what other appliances might be plugged into the same circuit.
