The main idea is this: as long as the evaporator doesn't freeze up, the one pipe setup will work as best it can. The reducer coupling on the exhaust pipe may or may not keep the evaporator from freezing. Rig it up and see if the unit short cycles. It might not do it until it gets pretty cold outside. If it does, a bigger exhaust pipe will probably keep the unit going, but by then the make-up air will already be eroding at your net heating factor. Trial and error will figure it out. Compared to a baseboard heater, the little heat pump has a long way to fall before it is less efficient, watt for watt.
