Also as far as water temps go you can easily raise the temperature of water by using too small of pipe creating friction loss but will need a water hammer arrestor to save your pump. you can raise and lower the water temps depending on pipe size and length of pipe, the longer and smaller the hotter the water gets.
We have a section of sprinklers that a landscaper threw in a decade ago and I always wondered why the water was so warm there and killing the grass and when I dug up the sprinkler he had run 75' of 1/2" funny pipe with 4 elbows. Run 100 gpm at 100 lbs of pressure and things get rather warm quickly
This would be for coldwater fish. Wouldn't want to raise the water temp.
