I currently have baseboard heat and would like to combine radiant heat off the return side. It would save a lot of issues with adding more zones, mixing valves and extra piping.
If I reduce the water temp to 160 on the supply side, will my PEX OB pipe work properly? Are there concerns of too much expansion with the higher temp?
