This is the heater we use:
Shop Oil Filled Tower Electric Space Heater with Thermostat at Lowes.com
I can recommend it highly.
Silent, constant heat (no blower on/off), no exposed heating coils so I don't worry about paper or a blanket touching the heater and igniting, no blower drying out the air/raising dust.
I do notice that some of the heaters in the article you sent exhibit red hot surfaces. I would worry about that in the confined space we have. I guess some people use catalytic heaters, but I would worry about any combustion using up the oxygen
creating carbon monoxide.
Somewhat bulky, slower to heat, heavy, needs shore power (any electric heater of course does).
We carry it in the car because of the smoother ride. Our unit has logged several thousand miles with no problems.
