Yes, I understand the pressurized closed system and the extra few deg that gets you. There are good & valid points here, but the 160 does SOUND good. I'm always open to a better way, and will take all this and experiment some. I like the sound of the RS high flow t-stat, I've seen lots of problems with the standard ones. I'll try the high flow t-stats soon. Was the 180 deg factory? Thanks everyone, Greg
