Wanted to ask what everyone thought about properly sizing a pool heater for our pool.
Our pool is 18x33 and is 54" tall
What btu heater should I be looking at?
Pool store said to buy a 200k btu heater but I was wondering if that's enuf to heat the pool up a little due to the cool nights we sometimes have in Indiana and would also like to try and extend the pool season.
I don't want to buy something and it be too small and have to run the thing 24x7, you get the idea
