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.
