Nothing to do with plumbing. Could be they had a slightly larger or deeper pool. Positioning makes a big difference. They could be lying in the water table and yours not. Shadows cast by property can make a big difference too. They may well have had a chiller running by mistake. Some pools (mostly kn the coast) actually need chilling to bring the temp down. If it was real icy and yours not, I would suspect that to be the case.

I suppose I should have qualified what we would consider to be 'a lovely temperature' - that is quite cool and fresh when you initially go into the water but becoming comfortable once your body adapts to the temperature. Then you can float about on the lilo, listening to music and let the time drift by. We visit frequently at this time of year and our pool was pretty much what you would expect.

Next door's pool was freezing though and we wondered if it was being filled faster (with very cold water). In any event, their pool was simply unusable even though the weather was in the 90s. Our friends contacted the management company who came and switched the heating on - actually too much because it ended up like a warm bath but that's another story. We wondered if the plumbing for their pool was somehow different from ours and it was being filled all the time with very cold water.
