I still wonder if heating a house with transistor is efficient. Gotta ask a scientist I guess. I mean there must be energy spent switching transistors back and forth.
- majewsky 9y agoWhat do you mean by "efficient"? That word is usually used to describe the fraction of energy that goes into a machine and is then not lost to heat. Since the purpose of a heater is to produce heat, it's pretty much impossible for it to waste energy.
- anonfunction 9y agoSome things produce more heat than others.
- PeterisP 9y agoFor passive heating, anything puts out exactly as much heat as it consumes electricity; there's no way around thermodynamics to gain or lose power there. Yes, there can be heat pump systems with e.g. underground connections, and pumping heat can be more effective than generating heat; but for pure heating, generating heat, the simplest resistor heater is just as 100% efficient as any complex electronic device, all the electricity spent results in just as much heat.
- rabidrat 9y agoAnd you know what happens to that energy when it's done doing its useful work? It's dissipated as heat :)
- adammunich 9y agoSome energy gets turned to light inside ba MOSFET but that quickly turns into heat too.
- ClassyJacket 9y agoIt's exactly as efficient as heating is with a resistor. That energy spent switching transistors is spent as heat. :)
