Be Carefull!! Infrared Heaters

[osiris]

Halogen type infra-red heaters are very efficient compared to hot air blower heaters. They provide instant localized heating on the person just 1kw or less is often enough to feel very warm. An electric hot air blower on the other hand must heat all the volume of air passing though it which often takes 3Kw to feel the same heating effect at the same distance away from the heaters. Of course they both heat up the room eventually but its a waste of energy to do this unnecessarily especially  where one is trying to save money.

If you want or need to heat up the entire room using electric then use Heat pumps or Air Con units which provide 3-4kw of heating for 1kw energy input. This is an OU device COP>3

bolt

thats funny you mention this ...
as i was yesterday  working on a unit that does this ... smaller scale ..  i was trying to acheive overunity operation .. 

but the  way i left the unit was like this .. 10w haligon  a 12 volt fan .. running along time on a small 12v battery
both operating on high frequency electricty .. a motor and a light  and i was recovering  to a boost cap to  close the loop

insted .. ill build a heater ..

can i call it the bolt?  i made a lot of videos of it .. and demonstrating  the effects .. witch are verry kool...
as i hooked up the cap the long spikes dissapear  i hook up the light and the motor  the medium spikes dissapear

and im left  with a nice wave   witch is the pulseing curcit  it is verry efficient  but NOT OVERUNITY..  darn close .. if i added up all the work and the recovered energy  it is ou .. but .. it aint good enough yet

the recovered energy  is to be pumped back into the source via ferroite transformer cap charger running low volt high freq  the concept is sound and i have prototyped all angles ..

ill keep at it ..  i post this hear  as it is IF and gets darn hot from 10 watts ...

You can run an infrared heater in a large space with
"nothing to heat" and the results will be abismal.

In a large open space, the infrared radiations will be subjected to dispersion loss if the air does not contain enough greenhouse molecules that retain the heat.

However, if the  space is foggy, or if the space is crowded with many people, the ordinary infrared heater will work. Water vapors, carbon dioxide and methane (from flatulence) are greenhouse gases.

Perhaps, this is the reason why a few railway stations in the UK are noticeably warmer than the others.

Not all the infrared lights are good. Some infrared lights hurt our eyes. The far-infrared lights from the sun have healing effects that benefit people with arthritis and/or heart diseases. Some materials on earth can generate a trace amount of far-infrared lights not very much different from those from the sun.
