hydronic coil placement for OWB

[JohnBob]

I need to install the hot water heating coil for an OWB. It will add on to a horizontal gas condensing furnace with an AC coil. Installing the coil on the return end of the furnace would be much easier than on the supply end due to space restrictions, refrigerant lines, etc. The two heating systems should never run simultaneously so is there any reason why this is a bad idea? The only thing I'm concerned about would be the high ambient air around the furnace blower motor.

Thanks,
John

I did this for the same reasons and have not had a problem.
