High Mass vs low massBoiler — Heating Help: The Wall

It is a low mass boiler, I suppose, since the heat exchanger (aluminum, small) holds only 3 quarts of water. It is cold start, and drives a high mass emitter (radiant at grade concrete slab) and a low mass emitter (Slant/Fin 2000). These run at different temperatures. Boiler has outdoor reset, and the reset curves are different for the two zones.
