"Remote" Heat Pump Installation

I wish to install a heat pump with the "inside" unit attached to an internal wall. This would involve running the pipes down the inside of the wall (approx 7 ft) and then under the floor for 15 feet to meet up with the external pump unit.
Is this possible? I'm aware that the units are generally fitted back to back on an internal/external wall, but I am unable to do that in my case. Any thoughts?

Dont know why are where you got that on heat pumps. You can put the inside blower coil unit just anywhere you like in the home with the outside unit any where you like there. If you go to far you will have to put bigger lines in . But thats a long way off. We try to put the blower coil near the center of the home if we can.

Approx. what size lines would be needed for a 3.5 ton heatpump with about 110' spacing? I'll have a trench open for some other work, so I thought I would throw in a pipe to handle the heatpump lines. Any help would be great.

Thanks Ed!
Would it be better if the two lines were seperated into two different conduit pipes or in the same conduit pipe?

For such a long split, how important is the insulation? Does the heatpump compress the vapor at the point where the heat is dumped?

I guess what I want to know, will be losing efficency due to line heat loss. Or will I be gaining efficency due to the higher winter ground temperature?
