    Another hydronic geothermal job

    Just finished this job and wanted to get a few pics up. Still waiting for Mech insulation, I will post updated pics when done. This is a fire station with 3 infloor heat zones and will have chilled water cooling later on from the 2- 10 ton heat pumps.

    Looks good, the only thing I do not like is in the middle photo the back wall.

    The 2 center lines straight thru the tee's will flow more that the outside lines that are on the side outlets of the tee's.

    how do you like the crimper?

    had any issues with it?
    It`s better to be silent and thought the fool; than speak and remove all doubt.

    I think there are circuit setters, moot point if so...

    Good eye, but I've got that covered. It's reverse return piped so that circuit #1 goes straight out but not straight back in. Circuit #2 is hooked up to the other side going straight back in so it's equal for both.

    See response to kevik about reverse return piping. Also no need for circuit setters as both circuits are identical footages nearly down to the inch. I didn't want to complicate it and add pressure drop when not necassary. There are PT ports on all 4 pipes of both circuits we checked pressure drop and flow is a spot on match. Thank you for responding.

    Is that diamond plate behind the controls?

    The propress tool has been one of the best investments ever. Looking back at all the jobs like this we used to do by soldering I can't believe all the time I'll never get back. I have never had a leaking problem other than human error such as pipe not in far enough or in crooked and snagged the oring even that only a couple times. I just hope the connections outlast me.

    I know squat about geo but the piping sure looks purdy....nice touch with the diamond plate haven't seen that b4.

    Pretty clever - I like how you did that.

    Depending on how long the circuits are (read- if they are very long and/or high head) - using the run or bull of the Tees won't effect flow in one circuit versus the other much anyhow. But, that being said, you thought about it and did the smart play by simply reversing the return path, so I'll just shut up. lol
