Answer to Question 1

Oil, water, acid, carbon, particulates, non-condensables

Answer to Question 2

 There is little to no effect on the warm air temperature being supplied to the building when the outdoor coil enters the defrost mode because the heat for defrost comes from the buffer tank, not the building.

 The electric heat is not required to come on during the defrost mode.
 The air-to-water system will generally operate with higher efficiencies at lower outdoor temperatures as compared to air-to-air systems.

 Can be used with hydronic heating systems.
