5000 doesn't sound outrageous to me. if you run the pool heater 24/7 for a month i'll bet it'll be easily 5000. my uncle has a house with a pool and they only run the heater for 1 to 2 days a week max for 2-3hrs during the summer (doesn't get used during the other seasons). his electric bills goes up to about 800bucks (at the current rates) during the summer. he doesn't use the ac during the summer, his reasoning is that he "heats" the pool so you can use it, so when you're hot gtfo and use the damn pool :chuckles:
