Some more ways to merge conventional hydronics and active solar energy subsystems.
Given the evolution of our system, there are piping details that are not optimal, but still allowed new equipment to be used with minimal disruption of existing piping. Designing such a system from scratch would allow better details. This month we'll look at some of those details as well as general design principals for matching up an active solar energy subsystem with a boiler-based hydronic distribution system.
