Hi all. I installed a John Guest single room underfloor kit years ago which heats an extension of about 25 m2. I'm very happy with it and it works beautifully! We are now planning a loft extension of around 16 m2 and underfloor seems to be the most logical way to go to heat this.
My question is, could I simply fit a two port manifold to the existing pump/blender unit to add an additional zone, or do I need to start again with a new unit? I'm assuming the pumps are all the same capacity?
Many thanks. Barry
