If you want to heat your entire house, most of the time electricity in any form
of direct heater will be the most expensive way to heat. The savings promised
from all these wonder plug in heaters comes from the trade of heating a room or
an object (ie people) instead of the entire house.
Quartz infrared lamps are great for a garage or other area where you want to
heat people or things, but not the air. As a bonus, they give out a lot of
light and lamp life is virtually indefinite. But electric BTUs are
expensive and I keep the burning hours short.
This type of heating does not make much sense for heating a whole house.
For one thing, with quartz infrared lamps, the heat is focused, not general.
If a house is to be heated with electric heat, I've found that baseboard
units work the best since they're usually placed to cancel out the heat lost
through perimeter walls and floors.
They produce heat very efficiently. They are good for one room or area. In
most locations, electric is very expensive and it will not save any money,
but you get one comfy room and the rest of the house cold for the same money
as burning oil or gas for the entire home. Not knowing your utility cost,
how much you want to heat, temperature, etc. it is not possible to make
accurate suggestions. .
A 5000 watt quartz heater produces exactly the same amount of heat as a 5000
watt resistive coil heater. Virtually all electric heaters produce the same
amount of heat for a given wattage.
I could imagine some with a 100-watt fan producing only 4900 watts of heat,
but that's about the extent of the difference. Even then, if the fan
"consumes" 100 watts, the fan is converting it to heat, so no real loss
But. . . if you sit directly in front of the quartz version you will
feel warmer. [if it really is emitting IR in the right spectrum- the
best won't give off any light and will be about 120-30 degrees if
