Understanding my system - Mixing valves
As I learn to use and configure my radiant heat system properly, I was reading about mixing valves and the need for a minimum return water temp to avoid corrosive condensation. Currently the mixing valves (manual type) for my two zones are fully open.
Tx151C boiler with SS exchanger (from what I can tell), no specs from manufacturer. Boiler temp is set to 37C (100F).
Any input from the pros?
