I use them all the time, in 2 ways. The simplest is as the diagram shows and could be fine provided you do not wish to have a reversing system to do cooling as well (or defrost, but there are other ways of doing that). The second one is to get a suction accumulator with a pancake HX inside it. The added benefit of this system is to take up the extra refrigerant when in reverse mode so the pot doesn't get flooded.
The pic I showed on the other thread shows my HP with both types on it. The main reason I am using it is that it will extend the operating range down another 5-8C
