The 1.5 tapping wouldn't be a problem; it is more than the 3/4 taps of the electric heater you thought of first. Actually it is what I suggested last January. The 0010 would still be the max flow ytou would need at the head required.
You would no longer need the phase III, but the boiler water sides of both can also be placed in parallel and used as the last on the series of domestic tank sides. The phase III has 8 gallons on the boiler side, but it has the 60 on the other side. As you did the test with 140,000 input and had no banging; the exchanger makes it act as if there is 60 gallons on the boiler side, since it is surrounding the water volume.
With 60 gallons of phase III storage and the Ergomax exchanger feeding more, the water heating problem is solved and you would no longer have to go to 180F to satisfy the demand. Keeping the water temperature down also keeps the boiler tubes further away from banging and sizzling.
As both the boiler feed and return and the system feed and return would be taken off the same two ports of the tanks, there would be no potential flow direction problem.
