Buy a zone valve and roomstat and throw the heating pack away. Where and why do you have a blending valve? No need as that would cool water..
I wasn't sure if I could do this or not. I didn't know if the UFH needed a pump and manifold. If I can just run it from an MOV teed into the existing CH controlled via a room stat in the conservatory then that's all good. Will the boiler cope with the extra load though? This is an example of what I was looking at: http://www.ebay.co.uk/itm/Underfloor...item5adf6d3aaa
