Hydronic heating water supply and return piping connects to a circulating pump and a mixing valve. The main loop feeds multiple radiant heating zones through zone headers, each equipped with a loop shut-off valve, two-way zone control valve, and a circuit setter. Each heating zone includes embedded radiant piping loops paired with a slab temperature sensor.
