Hi PJM, Swimking put my pool in also, in 2001. They are a very good company , they installed my pool from dig to swimming in 2 weeks. They have good customer service and are very responsive to any problems that may arise. I really enjoy the poured concrete steps running the entire width of the pool. We didn't get a heater, but our pool is in the sun all day and usually stays around 80-90 degrees. Good luck and have fun!
