The total no. of litres flow at final outlet ,must be nothing compared with continuous replenish hot with hot that happens within pumped secondary return , that stays hot so boosts leaching effect
personally if the manufacturers say dont use it, I wouldnt, as come the day it fails, you are in the pooh as the installer who has to defend your actions.

the manufacturers don"t say not to use it they say don"t use it on a continuously circulating return maintained at a constant high temperature, I f you're gonna quote the manufacturer at least take the time to read it and get it right!
Personally, I'd say mike Jackson got it spot on. It's not been approved for the relevant specification because its not worth the bothering financially.
Doubt it makes any odds, I'd be surprised if it wasn't tested for 24/7 use. Plenty of applications where heating could be on continuously and for them to release a product that couldn't withstand 'worse case scenario' would be utterly stupid.
I don't do nursings homes but I have clients that are from the Middle East. Usually seven+ bedrooms and bathrooms with servants quarters. They all come and go at different times throughout the year and the set up suits their lifestyle/needs.

the manufacturers say no to a return that"s on 24 hours a day why would you install a system that runs through the night, it should also be on a stat to stop the pump running needlessly, then again you would know that being an experienced plumber
