No. They are not unique at all.
In my opinion they still are pretty unique because their efficiency is higher than 100%. Which was what I thought the sentence would continue with when I started reading it. Cannot be stressed enough. It's like magic :] Sure your LED is more efficient than your incandescent light bulb, but it still produces heat which is not intended nor really wanted. In my book there's no comparing that to a heat pump. That being said, not really a fan of such sentences either.
- rjmunro 3y ago% electrical efficiency is not a useful measure. What matters is how much do I save (measured in money and/or carbon emissions etc.) compared to taking other measures, such as a more conventional heating solution, better insulation or installing solar panels. If you measure the efficiency of solar water heating in the same way, it uses no electricity, so it's efficiency is infinite.
