The Secret Society of Lathe Trolls

Thanks Andy. I guess even if you caught the 90-100 degree cooling water effectively you still need to get it back up to 180+ for steam ie. lots of energy still needed. I like the idea of heating a castle with the condensate return, lots of castles for sale here in Scotland. Maybe add a sauna in ther...

Regarding the cooling and steam systems. It seems there is heat required for steam generation and there is heat rejected during cooling. Interesting to know if there is any effective way to recycle some of that energy.
