I installed a system as above in a kitchen extension I built six yrs ago,the boiler is a combi,and the heated floor is in the screed with ceramic tiling on top.
Works like a dream,toasty toes
Only problem here is there is no control, heating on in conservatory will only be regulated by house room stat. I'd fit motorised valve on the circuit branched from the original and fit another stat in conservatory. So on a sunny day you can have heating on in house but conservatory switched off and soaking up the suns rays through the glass.

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..
