what all is included in the purchase? hoses? clamps?

I purchased the kit with 2 solar panels. It comes with pvc caps for one end of the panels. A rubber hose to connect the two panels together on the other end, as well as hose clamps. 2 pvc fittings for input and output flow to the panels. These are made to connect the filter hose to the panels. (although we bought new fittings to use all pvc pipe) It doesn't have any mounting hardware or rack to mount the panels to. So don't expect to have everything you will need. The picture on this ad shows more than what you will get. But performance of this heater has been very satisfying

can this be used to heat a [4 person] hot tub to a comfortably HOT temperature??

No. It only increases the temperature 6-10 degrees. If the water is hot then it may retain the heat & increase a little but would not be good as a main source of heat.

What is the maximum amount of gallons that this pool heater will warm up? Also, by how many degrees?

1 box of the S421P panels will heat up to 31ft round aboveground pool or 18'x36' oval pool. It can heat it up to as much as 15 degrees. SPQ Brands
