Loopcad Design

[Chennig]

I am a beginner with Loopcad. I downloaded the free trial from MrPex that just has a few MrPex add ins.



I put together a design (still needs some minor adjustments) and from what I have read, I feel maybe I am over thinking this to much. My thought was to have a more heat input (closer tube spacing) where my overhead doors are. Seems like a good idea, but is it possible to have to much? I have in this design tighter spacing around the overhead doors, but I made the design so that the start of the runs are sweeping across the front then breaking out to different areas.



Anyone see any issues with this design or have any suggestions?



I did back off the spacing in areas I plan to have cabinets, but I do want to tweak a little bit to center the heat more where I would be standing next to the cabinet.



28'x48' slab. Full frost walls. 2" foam under the whole slab and perimeter.

5 x 300' runs of 5/8" PEX.



Anyway, just here to collect peoples opinions.

You’re overthinking it. I used 1/2” pex spaced at 12” on my whole slab. No noticeable hot or cold spots. I would recommend 1/2 pex instead of 5/8. 1/2 is cheaper and easier to work with.

I already have the 5/8 PEX and manifold otherwise I would.

I have made some changes to this layout as I do agree it is over complicated. I have updated so the loops are easier to layout.

I do need to figure out a better way to start/finish so I dont have any loops jumping over eachother at the manifold. I would like my start and end for each loop next to each other.

Did you consider something like this layout?

I spent about 20 mins revising the plan to a rough idea of what I wanted to do.

I did want to keep tighter spacing around the overhead doors so I wanted to keep my design somewhat close. I did do a simple zig zag in a few areas as you suggested as the mess of routing around my pits was a disaster on the plan and was not going to waste a day just trying to figure out how to lay the pipe.

Surprisingly I was able to keep 4 runs at 300' and the 5th run at 292'. A part of me wanted to reroute that 8', but then reality kicked in and just needed to be done.

Later this week I will finish zip tieing the PEX and get the mesh chairs installed.
