Oh dear............. you have me worried now........... as I did have some minor concerns at the time.

When you say loop failures, are you referring to the loops in the screed?

Ive noticed an issue in our Master Bedroom, where by only one half of the floor is getting noticeably warmer than the other half, yet the flow rates on the manifold are the same.

Water not circulating through some loops and whizzing around others aka “bypassing.”. 
Just utter shite. 
Nu-Heats loop design was done by a 3 year old with lots of loops over 110m long, with 2 manifolds at one end of a corridor instead of one manifold each end etc. They went radio silent when it came to problem solving and passed the buck to every person in the company until I just ripped up their design and designed it all again from scratch myself ( with a pump for each manifold btw!! ).
