Is under floor heating more problematic than traditional radiator heating?

It's great 😃

It is also wise to check the flow temperature and make sure it is matched to the UFH. But there is a limit to how far down you can turn the boiler before it adversely affects efficiency.

Thanks.  How would I check the flow temp matches the UFH?

Photos of boiler, and ditto of any temp gauges on the manifold.

If your boiler has a digital temp display, see what it runs at in CH mode when it's been running for a good hour. It'll probably be around 50oC or so, which should be perfectly fine.
