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)

Do you have the latest Update 7 installed? Check your main menu which should look like this:

If you have anything other than this version please follow the instructions for downloading and installing here.

It looks like this 

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.
