    See, even after 30 years, you still can learn something new every day. Never even considered that aspect of a 3-way isolating the pump away from the expansion tank. Thanks, Dan!

    Hey, I've never used a diverter valve on radiant like this so, I'm kind of confused as to how it keeps the temp at design temp if its mixing hot boiler water downstream of the diverter. My brain makes me think its going to be hotter than intended. Also, where can I find these valves? I might have to mention it to my boss because all I ever put in were thermostatic mixing valves. Thanks!
