Why would i want a mixing valve for my indirect hwh?
recently installed Buderus WS-4 and S32 indirect.
the indirect's heat demand is being driven by it's Honeywell aquastat which I had them set to 140 degrees.
why would i additionally need a mixer off the boiler to feed the indirect? does that save fuel usage? does the lower temp used with the mixer reduce the recovery?
