Hi, I'm new to this forum and would be grateful if someone has any advice regarding the following. We are currently building a small kitchen/diner extension and I have underfloor heating planned for it. We are tight for space so am thinking of putting the manifold in the pantry cupboard I'm planning on putting in the corner. My question is: Do manifolds give out much heat? I ask because our condenser boiler feels cool to touch when it's on. Can the manifold be adequately boxed in with insulation (but also accessible) that it doesn’t give off heat if its put in the pantry? Thanks
