- ajb 4y agoThis page gives 1% loss per day: https://rondo.com/how-it-works https://rondo.com/how-it-works But clearly that's energy in -> steam out, not including any losses from converting from steam back to electricity for example. Although clearly they are targetting first processes that require steam as an input.

- bergenty 4y agoApparently electric heating is 100% efficient from some basic googling. I had no idea this was the case. So maybe the 98% efficiency is not totally bullshit.
- bibanez 4y agoNo machine has perfect efficiency
- laurencerowe 4y agoThe losses are heat. Resistive heating is 100% efficient. Use a heat pump though and you can get to 300%-400% efficiency because you are using the energy to move heat from one place to another instead of turning it into heat.
- bergenty 4y agoYou’ve got to expound on this a little more because 300-400% efficiency doesn’t make sense.
- Orochikaku 4y agoThe comment you're replying to probably meant to say it has a coefficient of performance [1, 2] of 3-4.

- Schroedingersat 4y agoReferring to COP as efficiency is an intentionally misleading practise pushed by the heat pump industry that makes communication worse for everyone forever if we accept it and doesn't really help anyone. Refer to it as COP or as moving 3 units of heat for one unit of input.
