Very true *IF* the older heater still consumes 1500 Watts... as has been said here, "1500 Watts is 1500 Watts". The gotcha is that over time, some heaters (such as the "ceramic" models) increase in resistance and no longer draw 1500 Watts. Over 5 winters of use, one that I have has dropped to about 725 Watts, as measured on a kill-a-watt meter... still is ok in my shop area, but no longer "toasty warm". :(

I remember when those were the latest fad in "better" heaters, several years ago. Thanks for the warning about them.

My favorites are the baseboard convector types. No fan, no noise, nice warm room.

I connected a 1200W one to a line voltage wall thermostat to heat a bedroom and turned off an oil-fired steam radiator. It's perfect.

I think hard wired wall heaters are the best still have worries about curtains and furnature being to close plus side no cords for pets to chew and to trip over...Timothy

That's a good point, and one of the big selling points of the ceramic heaters. The outside stayed cool to the touch, and if they tipped over on carpet they wouldn't cause a fire.

I have several of those type heaters. On one, The thermostat controls the heat output and it even controls the fan speed.
All the different makes, seem to be a little different.
