Ironic this thread came up, I'm borrowing one from a buddy to see for myself how they work.
Currently, I've got it running in the garage to help out a dog we took in for a family that just gave birth two days ago. The garage isn't a heated space, and it's uninsulated, so this isn't the best sample to see how it works, but currently I'm not impressed at all with it compared to our other $40 electric space heater we use in that same space.
I also see the infomercial on TV.
When I see Mr. Vila hawking items on the infomercials, I run in the opposite direction. Don't take that comment the wrong way, Mr. Vila knows some of his stuff, but I know from first hand personal experience that Mr. Vila will try to sell you dog poop on TV if he's paid enough. That tells me something about this companies marketing strategy.
Tonight I'll be placing that portable heater in a conditioned insulated room to see how it performs. When I take it back, my buddy mentioned we can take some meters to it, which I'll look forward to (never take something apart that you borrowed if you aren't prepared to buy another one).
Here is the problem though, depending on what kind of heat your house has, I don't foresee this heater being able to heat multiple rooms even with one of the HVAC systems circulating fan running. The question then becomes how much will it cost to bring another room up to temperature?
General rule of thumb that my father I'd like to think taught me well is that nothing in life is free, and if something sounds too good to be true, it usually is.
That said, I don't see the chances of this portable heater causing a fire, so I guess that's a good thing.
I wouldn't buy another, but am happy with the one I have
And with the one I'm currently using, I actually do like it, but there is no way I'd buy one.
They are WAY to expensive for doing what a $15 dollar heater can do.
And that's why I'd probably never buy one.
I'll stick to my warm floors myself.
Best comfortable heat for a home IMO. That said, live south of the Mason Dixon line and it gets hard for homeowners to justify the expense for that type of system.
