3 Oil Radiators, 3 vintage woodgrain Quartz heaters, and one vintage Titan electric. All work well. One of the Quarts heaters works on low only. I have moved and no longer need them. These were used when the power went out in the mountains. DeLonghi Oil is $65. Holmes radiators are $30 and $20. Quartz heater (2) at $45 and (1) for $20. The Titan electric is $50
