OMG this is hilarious. Autymn (sp?) is a complete moron. As an
electrical engineer, I can tell you with 100% certainty that all
electric heaters are 100% efficient. And efficiency is the ratio of
output to input (power out/power in, in the case of heat generating
appliances the inherent efficiency is 100%. In gas appliances the
efficiency can range UPTO about 95% for the newer 'ultra high
efficiency furnaces' as long as combustion air is supplied from an
unheated source [that is why you have 2 pipes going outside from the
furnace- 1 for combustion air and 1 for combustion gasses to be
vented]. No gas appliance is 100% efficient. ) Efficiency of heating
units DOES NOT DEPEND ON ROOM CONSTRUCTION. The lack of ability of the
room to contain the heat does not affect the output rating of the
heater, thus the efficiency is not changed. (Input is ALWAYS the same
no matter what). So autymn (sp?) why don't you do some research on a
reliable source (wikipedia is not considered reliable because it can
be altered by anyone without regard for their qualifications).
