: 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.
I was thinking of cutting the cold DHW water supply that currently goes to the Phase III and piping it into the Ergomax and then taking the outflow of DHW from the Ergomax and piping that as the supply into the PhaseIII, essentially preheating the water for the Phase III.
: 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.
As far as piping the Ergomax, would the house supply header and return to boiler be teed together at ergomax? And the return header from house and outflow from boiler be teed together at Ergomax? Would this be the correct way to do it?
Also, what would the storage temp be set for on the Ergomax? Would it be 150? If set at 150, when would it tend to turn on the boiler....at what temp? Would we be dealing with boiler condensation if that temp was below 140, say it cut in at 130?
