Looking at best way to heat up pool efficiently when designing our pool. I plan to get a robot so don't really need IFCS for "cleaning". However, friends who have one say they like them as they help to heat up the pool more efficiently. Can anyone point me in other methods of achieving this without investing in an IFCS. if its still worth having the IFCS even though we will get a robot anyways, certainly can look to do that as well. Just wanted to consider best practice/options for this use case.
