Clamp on a surface contact Honeywell control to the output of you current domestic hot water heater - wire it to close on temperature drop and open when it reaches 125 degrees - code set for domestic hot water out. then you won't need an anti scald valve and you won't need to change the PRV and the heater will run as it always did if you don't burn coal in the off season.
Pictures??? I posted some someplace of this! PM me if you want a copy! pump from the boiler coil into the bottom of the hot water heater and from the top (port out) of the tank back to the boiler DHW leg and thats your loop.
