Aren't 'triple' aquastats like the L8124A used to maintain minimum boiler temp to prevent flue gas condensation and primarily to maintain water jacket temperature for DHW tankless coils? It doesn't seem like you need to worry about either with your setup.

Not sure what you mean. I thought call for heat was a thermostat closure across TT.

Keeping the water in my hydrolic seperator warm is the intent. Setting the low limit to say 140, pulling btu from storage until it reaches 180. Leaving room in storage for more btu.
