So here's my wacky thought...... Use DHW to feed in as supply side make up water. Traditionally this hasn't been done for the obvious reasons...energy cost & scale, etc from the boiler. With my system, the DHW comes off a coil inside the heat bank, so the energy cost is negligible and because there is no boiler, there is less scale, etc. I also don't want cold water diluting my supply to the heat-bank. I could put the makeup water into the return line, but I would like to feed it into the system through an air scoop to try to get as much air out of the system as possible before dragging it thought the radiator loops.
Am I off base in thinking using hot DHW to feed into the system will help keep heat bank temps up, and not cause any further problems. Is there a fault in my logic?
