If you're looking to maximize round trip efficiency, this is probably not a good starting point. Better to use a heat pump, as mentioned elsewhere.
- rnhmjoj 4y agoYes, if you're counting the heat output as part of the useful energy, but parent was specifically talking about converting electricity into heat and back again.
- jbay808 4y agoSo am I. If you're going from electricity to heat for storage and back to electricity, you'll get better efficiency by using a heat pump to generate that stored heat. In general, sticking to processes that are as close to reversible as possible will be the most efficient.
- rnhmjoj 4y agoOk, I see your point now.
