Ironically, LEDs being so efficient means I need to use the central heating more often. My CFL TV used to provide some respite, not now I have an OLED.

- NeoTar 3y agoI hope your heating is more energy efficient than heating with electric light bulbs though! (And it should be - worst comes to worst basic electrical heating can be effectively 100% efficient, and heat pumps can do better)
- CaptainNegative 3y agoLight bulbs are also nearly 100% efficient, minus whatever fraction of light seeps out through windows or similar. As is just about anything else electric. Unfortunately that heat is usually suboptimally distributed, and pales in comparison to the heat pump effective efficiency which as you mentioned can go well above 100%.
- zerodensity 3y agoWhen is electric heating not 100% efficient? I thought they were by definition.
- dredmorbius 3y agoHeat pumps achieve greater thermal output than the input energy, unlike electric resistance heating. The latter is 100% efficient (all energy in is delivered as heat). Heat pumps exceed 100% efficiency, and can deliver 3 to 6 times the heat energy as input, as they are moving heat from the exterior environment to the heated space.
- FooBarBizBazz 3y agoLight bulbs are resistive heaters, and they are also 100% efficient at making heat. Some of it just bounces around the room as light first.
