EN-806-2006

Hi,

Hevacomp uses the Colebrook White equations for pipe sizing and EN 806 to determine flowrates. From the Help file:

Outlets can be added at any position. For HWS and CWS, an outlet type is selected, which will then determine the flow rate using either BS EN 806-3:2006 or BS 6700:1997 loading units.

RegardsSteve

It does not show the options anymore in the default window (EN 806-3 2006 or  BS6700)

EN-806 changes were introduced on V26. You would need to more to a later version.

I have V8i, do I have to update to V26?

which version V26?

I would recommend the latest one available but to Update 5 at least.

Hi, 

I have installed the updated version and I am just checking the CWS loading units of EN 806-3:2006, and for non-domestic kitchen sink DN20, the pipe size should be 22mm and not 28. That is not correct neither for 22mm nor 28mm: According to EN806-3 the loading unit for DN20 Sink should be 8 loading units.

Please advise!

Pejman, our developers will investigate the program code and standards, but in the meantime if you wish use alternative values to those in the software please use the Special outlet type, where you can edit the name and connection size to your requirements:
