Does anyone have any experience with the flat plate connectors? I'm trying to figure out if I can get away with my drawing and only have 1 pass through the xchanger before going into the electric tank? most installs would circulate the hotwater tank through the exchanger using 2 pumps. They also tend to have 1 pump sending to the panels and no storage tank so the entire system is just 2 pumps. With a storage tank I'd be at 3...
The goal is for a gain from 50 to over 110F passing through the exchanger at the same speed as the water is coming into the tank so 2-4 gallons per minute would be my guess. The hot fluid would be hopefully 130-140F and flowing at whatever pump rate I need...
