Still ancient thinking. The real new hotness is pumping heat around to where it’s needed, and storing it in a heat tank when it’s not. Heat pumping is incredibly efficient. Need to cool down a room? Pump it into the heat tank. Need to cook some food? Pump it into the stovepot. Done with the oven? Pump the excess heat back to the tank. Need a hot shower? Pump!
