This is my first year with the IWB. Been keepin the water temp. at 170.Thats worked out fine till it got colder for a stretch.I have base board. Just to see how this would work out I used 1" pex to connect the two boilers. Plan on re- doing with copper this summer. The question is what would be the max water temp.I can run at with the copper?
