Can solar panels to heat pool be used for other household purposes?

Hi there, my father just bought a house that has solar panels on the roof to heat the water for his pool. The water goes through pipes by the panels and flows back into the pool. I was wondering if there is any way to use that solar energy for other areas of the house. The panels were put in when the house was built in the mid 80’s and the house is in Central Florida/E. Orlando.

Thanks in advance!
