Is it more efficient to heat the domestic hot water in the indirect tank to 120 (or the desired temperature at the faucet? Or heat the water to 140-150, and use the mixing/anti-scald valve to bring the temperature back down to the desired temp by diluting the hot with cold, thus using less of the hot water at any one period of consumption.
