i have a vaillant combi (new) and have a flow/return for UFH as well as for the central heating. so i will be fitting 2 zone valves.

Do i need to fit a bypass valve at the same time?
 
ok, it says in the booklet

"an automatic system bypass is provided in the boiler........no additional bypass is required"

so no bypass needed !!!
