Want to use hydronic heat coils and an oil fired boiler for 2nd stage/Aux and emegency heat. Will install coils in supply plenum upstream of evap coils (30" apart). Some say no problem if both coils are active at the same time others say geo evap coil must be off if hydro coils are energized. any opinions

Evap coil needs to heat air before any secondary heat supply. If that is the case it should be ok to operate both simultaneously.

Blower has to be able to handle additional static imposed by the additional coil
