New to the forum - hope to learn a lot from experienced owners

We live in Charlotte, NC
Building a pool
About 19KG 36x27 at is widest
Our lot has trees around the backyard perimeter so only a few option for placement - putting it where the main sun hits (picture of backyard below)

pool will get direct overhead sun starting at 11a through about 3p - before and after shadows are cast from trees - removing them really isn’t an option

Knowing we will get 3-4 hrs of direct sun even in the hot and humid NC summer, we have opted for a Heat Pump to make sure we can maintain >82 degrees and extended season

Q: being in NC and only getting 3-4 hrs of direct overhead sun a day, what should I expect in terms of water temp (without heater) compared to neighbors who might have full sun 8 hrs a day - should I assume basically 5 degrees cooler than neighbors as a rule of thumb as an example

I also found a website (screenshot attached) where you plug in your zip code and desired temp and it tells you what the av. monthly cost would be based on average air temp per month - wondering how accurate this is from people who use a Heat

what else should I be considering ? Was a Heat Pump smart and needed in your opinion

Riddle, I see your question has been sitting for much too long without any replies. Let's try to fix that. I'm going to tweak your thread title in hopes that more NC residents key-in on your questions. Post back to keep the thread moving as needed. Good luck!
 
I’m sorry I can’t be much help with your particular question but I love the incorporated natural areas in the design! I suppose you could also have a solar blanket on your pool to help keep the pool warm

We’ve got a build going on in Charlotte too with a similar design.
Good luck on the build!

I think your pool will be plenty warm June-September. Heat pump was a good choice, it will be great in May & October. The shade will be nice during the hot months and keep your pool from getting too hot. Just get a good robot for the leaves. My brother in law has similar setup and climate in Knoxville. Good luck!
 
I'm always suspicious of the calculators that show a heatpump being so much more efficient that a gas heater. Unless your electric rates are absurdly low, natural gas is invariably cheaper. Also, heatpumps are much smaller capacity than gas heaters and take ages to heat up the pool. We live in Chapel Hill and our pool shaded for most of the day by tall pines. The pool gets up to 80 degrees in the summer and we use the gas heater in May and September.
 
Newbie here. Just found this forum today as I was searching for pool temperature expectations in Charlotte with 3-4 hours of direct sunlight per day as well. Timing couldn’t have been any better. I’m in a similar situation where many large Oak trees are creating shade for much of a given day. As I dig into it more, I’ll post any learnings that may come along the way.



BTW, who are you guys using in Charlotte for your pool builds? I’m currently working with a landscape architecture to finalize the design and haven’t selected a contractor yet.

Thanks!
