Is it best to mount the flat plate exchanger vertical or horizontal ? Also does it matter if it is higher or lower then the primary
tubes ?
-
It's a closed loop now with the plate exchanger so it makes no difference rather mounted vertically or horizontally, just be sure it's counter current flow!
-
Thanks Slimjim, I am trying like hell to get this system done but things keep happening. The company I work for just got sold this Wednesday so that just adds to the stress level of things :-[
-
Relax my friend, sit down, take a few moments to think, all will be well,

Sorry to hear that.
As long as the ports to your FPHE are not pointed down, thus allowing it to become air-locked. You should be OK, good luck with your build
-
Not trying to steal your thread but have a similar question...... I am going to bend up a bracket to mount the plate exchanger to the basement wall.... The wall is already concrete with plywood on it.... is it safe to mount to the plywood or do I need to get a piece of green board or something fire retardant to mount behind the exchanger? Temps wont be high enough to ignite the plywood right?
-
No they won't BUT the plate will get the plywood quite hot and certainly could destroy the glue, I normally mount the heat exchangers from the piping and off the plywood by 1/2 inch or so.
-
ok.... thanks slim.
-
You are welcome!, perhaps it's time to repost a picture of a heat exchanger / manifold that makes sense and perhaps it will help somebody with Ideas
-
I take it the valves with garden hose fittings are for flushing the HX?
-
You got it!
-
Hey Slim, I have mine sitting on a 2 x 10. Did I make a mistake ?
-
Not to worry Larry, you are fine!
-
Just a tidbit my father always pounded in my brain about copper piping,,, do not forget or skimp on your grounding wire and clamp. ;) :thumbup:
-
Sloppy I really ndidnt think about that but your right I have to do that. Thanks
-
Hey Slim here is where I am so far on the inside. Do you see any thing wrong that stands out other then the middle two secondary
flanges and valves are reversed. I have to swap them tonight when I get home. >:( I think it is coming along ok. I am putting two
1 1/2" ball valves on the tees on the bottom tube so I can pressurize the system with well pressure to make sure I have no leaks so far, cross my fingers
-
Looking Sharp Larry, nice Job
-
Thanks. When I get all plumbed up will you be available for a day or are you swamped ? I don't have a problem doing the wiring
it is what connections need to be made to make the system work properly.
-
It could be arranged but I have every faith in your work, I would bet that it won't be hard to coach you through it!
-
If I send you a schematic of all the electrical maybe that would help.
Thanks
-
That would definitely help!
-

No problem. Just know that most of the "pinhole leaks" etc. your ever hear about are really due to as stray current corrosion or electrolytic pitting. If anyone cares to read about copper pipe pitting, I can recommend the Handbook of Corrosion Engineering by Pierre Roberge (more specifically, chapter 11, section 11.4.3 ;) ).
Your installation looks like it is going well and that copper sure looks good. 8)
-
Ok, I might be a real PITA, but should the micro-bubbler not be placed a bit higher in the system??
...I have not personally installed one in my system, but I thought since air is usaully trapped higher in the system if it could be better located
-
It could be placed higher if you wish but since it is a Primary secondary loop the primary loop is always flowing and under pressure it will carry any air to the Spiro vent where ever it is placed, more important is it's spacing from anything that creates turbulance, circs, 90's and the like, the goal is to get the air to settle to the top of the piping and slow down going into the air seperator so it can be vented, the golden rule I use is no turbulance within 18 inches of the vent, this is not as needed with a Spirovent type air seperator like you have Larry.
-
Littlejohn, in the piping above the heat exchanger there is a tee that will have a Taco HY-vent installed when this is finished out
and that will release any trapped air in the high side of the system.
-
Sloppy, I wanted to make slimjim proud with the copper since he advocates the use of copper. The only problem is I could have put a down payment on a new truck with the money in the copper :o
-
Yes you could have but unless it's a FORD then the copper is a better investment and will last longer!
-
Slim I would normally argue about that but the 2015 chevy's and gmc's are plagued with rattle's and squeaks. I am a chevy guy
but may have to at least look at the daerk side for my next truck.
-
I knew that, just busting chops, I guess I'm in a good mood this morning, we got a lot done yesterday, I'm hoping to be done here by weekend.
-
Are you and Dan still working on the island ?
-
Yes we are, he and Joe got the last run of pex for the Ultra Fins done yesterday, we still have to install lots of hangers and the transfer plates on that loop then we can insulate the bays and close up the crawlspace. We can then concentrate on the upstairs baseboard loops, 3 of them all with separate controls, I would take some pictures but it's such a mess right now with all our crap lying around that you guys would laugh

I like to laugh... show me the picture slim. LOLOL!

Can't be worse than my shop, the one with a dad who thinks it takes too long to put anything away and it takes less time to look for it later and two uncles who still think they live on the home farm all use.
