One of my guys did a great job on these, except he put the expansion tank in the wrong place on the one as you all will point out, going to move it soon. Still work worth mention.

What an interesting way to do it...

I find the piping job on the Viessmann to be quite interesting. It's a good use of the little horizontal space. I assume that the Grundfos' are the FC type? Otherwise, you might get some ghost flow. I also like the little details of the manifold, like the vent at the top and the drain at the bottom.

I am also curious about the Munchkin. Is this a two family home or does the Munchkin concentrate on something other than heating the house (DWH, snowmelt, etc.)?? The tie-in looks very complicated for this mere homeowner.

Staging those two together might be an interesting option for very good turn-down ratios in the shoulder seasons, while maintaining the oompf for the coldest design days.

You mentioned the expansion tank already, won't harp on that... the beautiful piping more than makes up for it. Besides, plugging it into the spirovent should be peanuts..

Your apprentice did burn a couple of house components though. I'd repaint them and teach your apprentice about the virtues of flame shields or whatever they are. Homeowners get nervous when they see burn marks on wood.

Overall, to this untrained eye, it looks like a neat install. What are all the functions of this system, and how are you achieving them?

Constantin, regarding the burn marks, those are the domestic plumbing lines, not ours. Whew!
Regarding the two boilers, the Munchkin is for all the radiant floor heat and the domestic. The viessmann is for the high temp radiators and water to air handler units for the older part of the house. This is appx 10,000 sft. Great client and great General. I did the first remodel 14 years ago and now redid the mechanical room and 3000 ft add. Thanks for the words.

good job

Looks good. A few questions...

Do you have trouble with a curve developing before you solder with that many tees in a row? For us, after about four, it seems they have a little bow to them. We've thought of getting a T-Drill just for manifolds. Also, are those Grundfos UPS15-58FC superbrutes?

Overall, the work looks real good. Give that guy a raise.

Nice work for an employee!

Nice work

Mark I know what you mean about a curve developing with a lot of tees in a row. A T drill seems like an interesting idea to fix that. I've never used one, only read about them here. Is it a good thing to have in your arsenal of tool/toys for piping endeavors? WW

I looked into the T-Drill...

... I think it's a great concept, a T-drill system could be perfect for manifolds because it'll eliminate a large number of soldered joints (less labor, lower flow resistance), there is less reaming to do, and the spacing of the secondary/tertiary take-offs is pretty much entirely up to you.

Plus, you can create custom-sized holes, all on the same manifold w/o the need to stock a whole bunch of "T"'s in different sizes. This means less walking back and forth to the truck, fewer inventory hassles, and more productive time on the job.

Besides the initial cost, I suppose the lack of awareness and the material quality issues that plague the industry are probably retarding the adoption of the T-Drill system in the US. Perhaps someone has some field experience? Me looking at their promotional videos way back when isn't exactly the same thing as trying to use the system...

Considering the issues that some of the installers have had here with their copper pipe supply going wonky in terms of material properties, the T-drill users would be the first to find out that the "annealed copper" was off...

One way you could spread the cost over several jobs is to pre-assemble the primary manifolds at the shop, thus making the T-Drill work on several jobs at the same time.

tim smith

yes they are 15-58FCs

Constantin

Wheee!

I guess this is one way for you guys to differentiate your work from the next guys... "we WON'T burn your house"...

I had a couple of less-than-happy AC installers when they discovered that their allegedly-tight brazed Cu return pipe actually had a leak in it that required them to undo Icynene around it and braze it shut. Talk about smoke, not matter how well you try to shield it!

Thanks for the clarification, it is a neat system.

Glen

very nice

re the manifold - try these! It does not completely eliminate the small bowing of a long manifold - but it does save a lot of time.

or you can try \"quick zone\" from zurn..

if you are doing radiant, you can build up as many as you like - with bayonet mounted sections with orings in them
