Thanks you for the nice comments. Brian and his crew are the ones who deserve all of the credit. I have the easy job- close the deal and stay out of the way!

Brad, the strut that we used on this project came from Hilti. This is in a 9,0000 sq. ft. custom home that is about 1-1/2 yrs. old. Shoot me your e-mail for more details.

Constantin, Brian and I sketched out a piping diagram and Brian put the pieces of the puzzle together. As you can see, space was very limited. We have had very few Pro-press problems and the problems we did encounter were self induced. We have multiple glycoled systems with no problems as well. I endorse Pro-pres with no reservations. -DF

    Prestige

    Brian and his crew finished piping this one last week and did the start-up and commissioning yesterday. It consists of two Prestige 175's, a TR-120 tank, and a Caleffi Hydro-Separator controlled by a tekmar 265 staging/reset control and a Wirsbo 201 mixing control.

    The system feeds about a dozen radiant zones, five AHU's and a garage zone isolated by a Flat Plate heat exchanger. -DF

    Nice work, Dan & the crew

    Good job Foley Mechanical! Nice work, as always Dan. Quite the system. I noticed that you used the Caleffi auto air vent, high capacity. We've been using those on our chilled water mains with some of the buildings on campus. Nice vent!
    I'll betcha those Prestige boilers run smooth as silk, especially with the Tekmar.

    Dan- Another Defining Project

    from you and your crew. Hat's off to Brian and his team!

    I love the use of Unistrut (or whatever system you use). Substantial, neat and safe. Outstanding work as always!

    So, I have to ask, what was there before? I noticed small footprints so these did not replace an old iron behemoth. Plus the structure from what I can see is fairly new.

    Tell us about the project- house? Apartments? How many SF? Just to get an idea of scale. How old is it?

    Beautiful work

    My hat off to you and your crew. I presume that you continue to have faith in the Propress systems where others have wavered.

    The pipe layout looks very methodical... and beautifully executed. Did you guys work off a plan or was this "freehand"?

    The cable layouts, raceways, etc. also show a fantastic degree of attention to the details. The Caleffi bottle is big enough to double as minor buffer tank... and the cabinet around it is intended to be closed later on?

    The work that went into the piping, the many shutoffs, and the supports just shows how much you guys care about longevity, silence, and maintainability.

    What I have seen amazes me and I hope that the homeowner feels the same way.

    Fine work

    An atta boy for Brian. Maybe a raise!

    Are thse press unions below the boiler on the copper?

    Also I wonder about the check on the bottom right of the Caleffi? Does it remain quiet? Is it needed?

    HR

    Hi HR,

    In order:

    Yes, Brian did an outstanding job and is well deserving of a raise, even if he is presently well compensated!

    Yes, Pro-Press unions below the boiler.

    There is a check valve at the return of the primary loop to the Caleffi Hydro-Separator. It is required to prevent reverse flow when DHW calls, which is a parallel load (primary pump does not run when DHW calls). It is not noisy. The only time I have had noisy checks is when they are immediately downstream of the pump. - DF

    A tip!

    Dan,

    Like always, you and your crew do some great work. In my travels I get to see a fair amount of installations (Good and Bad), few ever compare to your photos. One trick I would like to pass on to you and your guys refers to the name plate on the Grundfos UP circulators. If you take a small straight blade screwdriver, you can carefully pry off the plastic cover, it snaps off allowing you to rotate it so it's in the proper position regardless of the way you mount the circulator.

    DARN !

    H.R. beat me to the question on the swing check! Good eyes buddy!(NICE soldering too!)

    I was going to ask exactly the same, so thanks for the explanation Dan.

    Amazing work by Brian and the crew...

    Dan, as always...keep posting the photos. They are a true inspiration for us all. Chris

    Dan,
    Concerning another one of your jobs. Did you ever get the fuel data from the horse barn project? I realize that Prestiges were running to heat the building during construction, but if you could find out how much propane was used, I think it would be interesting. Just in your spare time! :-) Thanks!
