Rondo. I'm glad you enjoy the benefits of the Eden pure heater but I don't think it produces any more heat than most other portable electric heaters. The gentleman in the following you-tube video ran his own tests and I'm sure others have as well, including some consumer organizations.
I'm only mentioning this because of their cost. Please don't take offense. My background is electrical and electronics so I tend be skeptical of some claims made by companies regarding their products.
