In last month’s “Heating with Renewable Energy” column we discussed how to size supplemental heat emitters that allow the supply water temperature to an existing distribution system to be reduced.
The next step is to pipe those supplemental heat emitters into the existing system. As with most things hydronic, there are multiple approaches, and the “best” approach for each installation has to consider cost, aesthetics, access to the existing piping, available wall space and the goal of how the overall system will operate based on existing or newly created zones. We’ll look at basic concepts that can be tailored to individual system needs.
