for product safety and consumer safety. they are wasting that 1kw-2kw energy but not producing the maximum achievable heat out of that energy
meaning they are not even approaching the limits of physics
Can you please elaborate on what happens to that energy that is not turned into heat in an electric heater?
Because unless it is either magically sent back to the grid or it's used to electrocute everyone in the room it does break the
first law of thermodynamics.
So do enlighten me on what happens to the "wasted energy" in a heater or elaborate on how you feed a system 2 kWh and you get out only 5 MJ or 3MJ and not 7.2.
do i really need to explain common sense real life stuff that people learn from just living their life and experiencing things.. .. seems i do
so sit back take your hands off the keyboard. and read for next couple minutes. you might learn more in a couple minutes than you have in years
and no replies with debates about my tone, manner or expressing my reply negatively.. you asked a silly question so deserve a less than pleasant lesson(yet again)
firstly
i dare you to take 20 different (randomly picked) heaters all using 2KW and i guarantee you they all wont be emitting the same radiant heat.. at the thermo dynamic efficiency limit you think heaters work at..
you want to imply they must all be following some max efficiency of some natural law of all converting 2kw into Xmj of heat.. that no other product can surpass... you will prove yourself wrong instantly by test driving heaters..
scared to try? well lets move on to the other thing you are not sure of
as for your question of where does X energy go if not used to produce heat
not all materials produce the same heat from the same electric current flowing through them. also many heaters also produce light as part of the heating element (halogen heaters)
alos regulations prevent devices described as heater rom going too far in regards to heat.. its called fire safety regulations, where by energy is wasted BY DESIGN for comfort and safety..
yep if one material can radiate a space of 2metres using a intense light(halogen) heat system.. some regulator would come along and say the light is too bright and can burn somones retina's or their skin if too close so they use a less efficient material to get the heat without the light.
thus devices do not function at the max limit of thermo dynamic law.. by design
or from the other side of convection heating some materials can blow out enough heat to radiate 2metres space and again regulators will say thats great for people at the 2m circumference but anyone touching the unit will sizzle their hand off touching it or the unit might produce a house fire. so again. design changes to dampen down things
if you think room heaters are just left to "cook" at max temp of the energy input efficiency. you are sadly mistaken.
oh and good quality material that can work efficiently to convert energy into heat without reaching extensive heat that can burn or ignite nearby objects, but these comes at a cost. so those making CHEAP heaters dont use those materials so more energy is required to heat up inefficient material.
"energy rating" appliances are not based on efficiency of thermo dynamics efficiency limits.. .. its based on a arbitrary amount lower then that.. deemed acceptable to regulators as "efficient" in regards to known materials manufacturers deem cheap/safe to be plausible to use for consumer goods, by which making those products wont risk a companies liability or risk
oh by the way..
i can cook eggs and bacon on this 1kw appliance

yep.. i travel alot mainly in hotels, guest stays.. and sometimes i tour around
i see many people in caravans/RV's open their windows in the morning when they cook breakfast because their 1KW cooker fills their caravan/RV with heat faster then the silly 2kw halogen heater does at night, where they still end up needing blankets and extra things to get warm
