Does there have to be a pump between the boiler and either the Danfoss valve or the crossover between the supply/return?
Or can the pumps be located outside of that square?
The picture I attached shows what I am talking about.
I ask the question because the way my plumbing is done currently makes the config on the right MUCH easier. In fact, I am not even sure I can do the config on the left.
