Can anyone advise please - im looking at add another rad about 4 feet away from this one in to the conservatory. It's microbore I believe. Can I simply tee off the current pipework or will it have to come off the manifold. Where would the manifold be? Under the floorboards by the radiator? It's a 4 bed house, how many manifolds are there likely to be. Any advice please. I have contacted a couple of local plumbers but nobody seems to want to do a small job like this.
