I have experience installing both types of systems. I have a number of clients in Tacoma. Years ago I used to only recommend the partial system, however, my experience the past few years is that pitch is more effectively maintained with a full system. Many forced air heating systems create a fairly dry environment during the winter. One theory I have as to why the full system is more effective is that the air beneath the piano is constantly moving with a full system. One important caveat however, is to make sure the client understands the need to keep the full system properly serviced. I now recommend distilled water if possible with a minimal amount of humidifier treatment. I find the build up of minerals on the heating bar and pads is greatly reduced. If the client is not that keen on keeping the system maintained, I recommend the partial system, since it is basically care free. It is true that we have a wonderful climate for pianos, and many 100 year old instruments are working surprisingly well. But we still get significant swings: I tuned my son's piano teachers Steinway "M" in may. When I last checked it a couple of weeks ago, it was at 444 - and the octaves across the break sound pretty nasty. With a full system, you can almost keep the piano in good tune throughout the entire year around here. More time for voicing and regulating!
