I'm trying to understand what kind of balancing valves are available for a hot water recirculation system operating on a PEX header system.

I found lots of examples of headers and valves designed to balance a radiant heating system but none of those seem to apply to domestic hot water usage. Most of the manuals are silent on the topic or give dire warnings about the warranty being void if you are not using these headers for the intended purpose of radient heat.

So any pointers on what is the best balancing solution for a hot water system like mine?
The water only wants to flow to the shortest loops leaving the long loops cold and defeating the whole purpose if we don't put something in to balance the system and put some head pressure on those short loops.

Do we just buy the radiant heat headers and use it for domestic hot water?
