Additional manifold required for underfloor heating?

Underfloor heating is being installed as part of job that includes a ground floor located boiler. It has been proposed that in addition to a manifold for the zone adjacent to the boiler a second manifold (requiring a dedicated pipe from the boiler running to it) is required for the second zone that is a 30sqm area and 8m away from the boiler. Both zones are on the ground floor. This is rather than using a single manifold at the boiler for the 2 zones. Can this distance from the boiler require an addition and costly manifold?

any guidance appreciated

As Dan has rightly stated; it depends on many factors. The manifold/s for example can be fitted with actuators to control any loop or zone. An actuator with a microswitch can pull on the boiler etc.

Yip, to many variables for a yes or no.

But as a "to be sure measure" it will be better the way that has been proposed than to have a single manifold at the boiler

Hmmmm well not strictly the case SGM. You can do it with one manifold & the right actuators, while you're always limited by the flow rate & the the number of loops attached to that one manifold. But we are all guessing without further details from the OP.
thanks for your prompt replies. I will seek more information about the project and post again later.
