Extending water UFH to attic

[dewsbury]

Hi, I have 5 bed house with underfloor heating on all 3 floors.I also have converted attic. UFH was installed in year 2000.
I want to put low temp rads in attic (it currently has no heating!) and feed water from UFH on floor below.

Question 1: Is this a sensible approach?

Question 2: Is this easy to do? Any decent plumber can do?

Question 3: See image from manifold directly below attic. I think I need to run a pipe from this manifold upwards to the ceiling and into the large converted attic. I'm trying to figure out where to make the hole in the ceiling - in advance of plumbing work. I've put some numbered circles on the attached picture. Where in the manifold do I attach pipe that will go up to ceiling?

NB: I also have a second manifold in another room.

From that pic, nowhere. You would need to tap into pipe prior to 2 port valve that controls the manifold.

Thanks Simon,
Maybe this second photo makes a difference? This is a second manifold in a different room. Could this be used to run up the attic (low temp rads).

I had this system drained down and serviced recently. The guy who did it has 20 years+ experience with this stuff. He indicated that it would be east to get heating into attic???
