What heats a person in a garage better?
$100 Costco Parabolic heater
$100 Costco Ceramic Space heater
An old friend of mine is cleaning up his tools and he has the cars out of
the garage which is very airy (because it's a garage) and hence very cold.
He wants heat.
I want to give him a gift.
Which heat is better?
Parabolic
Ceramic (resistance, with fan)
One "throws" the heat, as I understand it.
The other "fans" the heat, as I understand it.

I'm worried that he's so old he'll hurt himself on the "hot" to the touch >parabolic - but on the other hand I'm worried the ceramic "fan" heater
won't throw enough heat to matter (since a garage is airy by design).
Any suggestions?

The main choices for workshop heating are:
- Forced air
- Radiant (infrared)
- Wood Stove

the same amount of wattage.
Depending on how much power he has in the
garage he may be better off with 2 or 3 of some $ 25 bathroom type
heaters.
When you depend on answers from 'AnswerBag'.... The models that
incorporate one or more motors for fans or rotation would be less that
100% efficient although I doubt they would use 20% of the input.

In some cases the wood stove would not be allowed. Definitely if he puts
the cars in the garage. Solid fuel heaters should not be used where
flammable liquids are stored.
Normally, inefficiencies in electric, gasoline, steam, gas and any power using devices show up as wasted heat. But in a heater, heat is the
goal.
How can there be waste heat? How can they be less than 100% efficient?

Even the motors generate heat, so it is still 100 % efficent unless you
count on the power dropped in the wiring in the house going to the
heater. Fuel powered heaters that are vented to the outside will see
some of the heat going out the exhaust pipe.

Good point, so let me make my quesiton specific and explicit. In an *electric* heater, heat is the goal. How can there be waste heat? How
can they be less than 99% efficient?
Even the cord to the heater doesn't get warm so waste heat in the 14 or
12 gauge wires going from the breaker box to the room will not be more
than 1% of the power used, certainly nowhere near 20%.
Why do heaters
claim efficiency as low as 80%?

I replaced the #14 wires to my bedroom with #12, and was amazed by the >increased heat from the 1500 W bedside heater.

I've never seen on that did.

the garage which is very airy (because it's a garage) and hence very cold.
Two possible plans.
Put the cars back in the garage and there will be a lot less air to
heat.
Wait until summer. Spend the winter doing crossword puzzles where it's
warm inside. Or writing his memoirs.
