This was my first season owning a pool. I think we got to use it maybe 15 or so days all summer because the water was always freezing. On the original bill of sale (11 years ago) the previous owner had a "heat" system listed. But it doesn't have a heater, it doesn't even seem to be room for one where the pump was installed. Maybe it went out, maybe they changed their mind. We have a layout page with what each pipe goes to. One of the return lines is labeled "heat plus". Does anyone have any idea on what that means? I think next year we may invest in a heating system if we can afford it. However I have no idea where this heat plus pipe was going?
Also just for future reference considering our pool was always cold, and we had many days in a row in the upper 90s. Is there a better way to run the returns to help conserve heat? The solar cover didn't seem to make any difference as the pool temp never came up during the day. I had this idea that maybe not pulling in from the main drain as much might help or vise verse.
