Underfloor Heating On First Floor

[Andy C]

I have installed underfloor heating on the first floor of my property . 15 loops that drop down a wall on the ground floor. As all of the loops drop down the wall can a manifold be installed on the wall upside down, or may this cause possible air locks. Is it best to extend a 12 port manifold to 15 ports or use a separate 8 and 7 port manifold in parallel or series with a circulation pump.

You would be best talking to the manufacturers / supplier of your system.

Send your drawings/ room sizes snd layouts to an underfloor heating supplier.
They will do all the calculations and advise you on position.
10 ports is normally maximum. Depending on the size of loops.
