I was in Lowes looking for a space heater and saw several different
1500W models. Some as little as $20, and others like the Vornado and
those upright tower heaters for like $100. Does one model heat better
than another? I thought all 1500W heaters put out the same heat.
True enough, the difference isn't in the amount of heat, which is obviously
the same. The difference is in the quality of the build, the safety devices
built into the better heater, which will be reflective in how well it works
and how long it lasts
1500 watts is 1500 watts. I also looked into those things Paul Harvey was
pushing and from the ads it seemed they had changed physics and kept the
heat around you and it wouldn't rise as would normally happen! Those were
very expensive and also 1500 watts. You only get 1500 watts out no matter
how deliver it through light bulbs or heated wires.

Evidently, it appears that the real need is in the *distribution of heat*, and
in every case it appears that a space heater on the floor might heat our feet,
but eventually heats the ceiling and at that point might be lost. SO, it seems
that distribution, re-distribution is the most important factor.

IIRC, there isn't, but there should be, a standard specification on the
BTU transferred to the room; a heat exchange efficiency rating if you
Example: I have one of those oil filled heaters that looks like an old
time radiator. It just sits there, and the air right near the heater is
very warm. 3 feet away, it is slightly warm, but at 6 feet away little
usefulness. Do a Google on your Vornado, and read the hype at their web
site; it doesn't appear the Vornado just sits there.
I like the oil filled radiator style because they are silent. We have
ceiling fans in every room so they work well.
If the Vornado is very very quiet then It may be good to look into?
Otherwise it's just a fancy version of a $14.88 fan heater from WalMart.
For any heater type remember that if you just heat the air the room will
not be comfortable for very long. You must heat everything in the room
as well. furniture, walls etc.

You mentioned this just when I was thinking about these ceramic
heaters. Seems about 10 years ago they were the big rage. Lots of
advertising claimed they were superior and put out more heat than
conventional heaters. Their small size was a selling factor too.
Every hardware store and other stores that sold things like this, had
one on display that was working in the colder seasons.
I was never convinced because I know that you only get a set amount of
heat from a set amount of electricity. But lets answer this once and
for all. Its got a ceramic core, but isnt there still a glowing wire
inside that core? If not, how do they work?
It does have some sort of resistance element in there to convert amps
into heat. But the resistance element is part of the ceramic "core"
which also contains many passages with air flowing through it. The
heat from the resistor is conducted through the core to a large amount
of surface area for transfer to the air. Because of this, no part of
the heater core gets very hot. It might still be capable of burning
your skin if you touched it directly, but there is nothing that glows,
nothing hot enough to start most combustibles burning.
So it's no more efficient than any other resistance heater at converting
electricity to heat. But the low temperature makes it safer than the
glowing-wire heaters, and the heater core with lots of little air
passages probably makes it easier to add a fan and direct all the warm
air in a particular direction.
I beleive the 1500W refers to how much juice they use. As others have
pointed out there are various ways to use that juice and / or distribute
the heat. Suggest you google something like Differences in electric
heaters. I just did and got a lot of hits:-))
