Raypak for the heater. My friend has a Pentair and is jeleous of my raypak. Get the 406kBTU, unless you have a limited gas supply line.
This Forum seems to have a Pentair Bias (as do I). I only have experience with Pentair, (except my heater is a Raypak), and had trouble with my SWG. Pentair stuck with me, figured out the problem, (as well as a few others here), and I really appreciate that. And they sent me the corrected part overnight. My preference is to never have problems, but it is good to know they are going to back their stuff when you do.
My Pentair Quad DE filter is a really nice cross between a cartridge filter and a DE, with the benifits of both and little of the downsides.
My VS pump is really quiet, powerful when I want, and efficient.
And the automation is (now) easy to set up, adjust parameters, and I like the emails it sends me telling me the status of the system, because I only need to check and adjust once a week, and if anything ever goes wrong, I would want to jump on it right away. I especially like the IntelliPH and how it rins with the intellichlor.
I will I'll also say my neighbor has all Hayward, and has not had as much luck. That is not a big cross section so take it for what it is worth.
