: There is no purpose in using 15 psig in the steam coil for heating, as you don't want 250F coming off the steam coil. Reduce the pressure to just that needed to pass through the coil.
Good point. However some of the other equipment does run at that pressure. I really should look into lowering the main line pressure to 5psig and see how everything reacts. I found a solanoid that should do the trick for on-off control of the heat. From what my electrician said a regular thermostat should be able to pull the 24v solanoid in.
