What is the consensus regarding energy demand for a pool heater?
I'm trying to figure out what uses the most energy:
keeping the heater on and set for 86F 24/7?
lowering the heating temp to 80F when not in use? (this is what i've been doing for the most part)
turning it on only the day i need it?
We usually use the pool monday, wednesday and saturday/sunday.
gas heater 400,000 btu
day temp are in the 60-70
night tamp are 50-60
the pool is in a green house
Is there a more scientific way to calculate/predict the most efficient way?
I know it s a pretty hard and general question to answer, just wondered what people are doing...
