Hi,
Its been a while since the last time I used Hevacomp so apologies if the questions seem trivial.
I am trying to model a relatively large project, I have already placed all my emitters (some ceiling void, some floor level).
When I try to connect the emitters using separate flow & return pipework, it appears the emitters may not be connecting. Zooming in shows that the grid doesn’t seem to always line up with the connection point of the emitters, as i’ve modelled some of them at 45 degrees (see figure below) I’ve tried checking this in the isometric view however due to the large building it is quite difficult to check. Is it ok to model the emitters at 45 degrees? And is there a way to check whether they are connected?
My other question is regarding the system marker. Do I need to place it on the flow or return? Or do i need a single flow & return pipe?
Thank you in advance
Seb
Hi Seb,
Good morning, apologies that this post seems to have been left idle until now. I have just seen this and would be happy to assist.
You will need to connect the emitters as shown in the following guide:
Connecting emitters to a reverse return system - Hevacomp Wiki - Hevacomp - Bentley Communities
Specifically:
you must use a combined Flow & Return pipe to connect to Emitters. You cannot connect separate single flow and single return into them. The same applies to the System Marker which also needs to be placed on a combined Flow & Return pipe.
I hope this helps answer your questions?
Regards,
Shane

Hi Shane,
Thanks for the reply, I managed to figure it out in the end! I have gotten to the stage of sizing the system, however I'm being presented with an odd issue..
I am getting an error with the pipework, however the issue seems to disappear when I go to fix it. See images below
I've tried remodelling the are but it doesnt seem to work.
This usually means that the pipe layout is invalid, please find details at:Netsys warning - Closed loop found in system - Hevacomp Wiki - Hevacomp - Bentley Communities
Hope that helps?
Thanks Shane,
It seems the pipe was actually on another floor, managed to get it sorted.
I am still running into a whole host of trouble with the emitters which I don't seem to be able to resolve.
I am getting an error saying that they are not connected to a flow & return system, however I think they are. Is there a specific order you have to draw the pipes in? I have attached a couple images below.
Would you be able to take a look at the model to see if I have done anything silly?
Thanks for your help.
Sure, no problem - please upload the zipped project folder to this link.
Morning Shane,
Thank you for this - just uploaded.
Did you have the project open in Hevacomp when you zipped the project folder? All the files have not come through - only the below:
Could you please close Hevacomp and rezip and upload again? (Note the above is the only folder I need - no DXF's or anything).
Thanks,
I may well have done - apologies. Are you ablt to create a new upload link as this one doesn't seem to work anymore.
Thank you
No worries. I will log a Service Request for you so we can communicate directly on this, I will email you shortly.
