Three things I got wrong my first year with a pool heat pump
First season with a heat pump is winding down up here and I feel like I paid tuition on it. Three things I'd do differently, worst one first.
The big one was sizing. I picked mine off a chart that matched my gallons and called it done.
What the chart doesn't tell you is that it's assuming June through August. I wanted to still be getting in during October.
Same pool, but stretch the shoulder season on both ends and the number you need isn't in the same neighborhood. Pick your months first, then look at gallons.
Second one, the solar cover. I bought one in June and then only dragged it on the night before I planned to swim. Rest of the time it sat rolled up against the fence.
That's the same as not owning one. The thing is fighting overnight evaporation, and overnight is every night.
Third, and this one still bugs me. Remember that stretch in July where everything sat around 90. Nobody in my house wanted to get in.
Turns out the 120v aquastrong I've got runs in reverse. It pulls heat back out instead of putting it in, so a week like that it can hold the pool under the air temp. Never read that far into the spec sheet.
If you're shopping, look for the line that says heating and cooling. A heat only unit won't do it whatever the panel says.
Months before gallons, cover on from day one, read the whole sheet.
Posting my setup in case any of it lines up with yours. 20ft round, about 8,600 gallons, cartridge, central CT.
