I am not aware of any books that will provide what you are looking for.
But, there is a lot of information is past threads if you search for it.
If you ask specific questions ... no matter how many ... then you will get specific answers. BUT, you may be getting too picky. As long as you stick with any of the major brands, pumps, filters, SWG, etc are pretty comparable and often there is no "best" just personal preference.
Here are a couple tidbits that may or may not help:
- Raypac gas heaters seem to have a good rep here
- Pentair SWGs are limited to 20% increments ... unless you have one of their automation systems and then you get better control
- If your electricity is relatively cheap and you do not need a lot of varying water flow rates, often a 2-speem pumps makes more sense than a VS pump
There are just a lot of "it depends" answers to many questions when there is not enough information.
