[QUOTE="hupte, post: 5228778, member: 74586"] the heat exchanger is so you can run the boiler pump 24/7. gotta remember those waterlines will get cold if the water isn't flowing. that means there is a potential for freezing. also it shortens the length of time needed to get hot water in the house between cycles. also keeps the indoor plumbing separate. allowing the possibility for using anti freeze in the house. also some applications inside the house require a closed loop system for flow dynamics, and trapping air, etc. since boilers are an open system the plate HX alows for this, just to name a few reasons. I agree about the pump flanges. why would you want the hot water to stay on top of the tank? isn't it gonna stay there anyways? heat rises right? Also why would you want to reduce mixing? usually you want the water to flow to avoid the potential of corrosion and mineral deposits, also to keep the water at a more consistent temp. perhaps i'm misunderstanding your some of the details about your system?
