I suppose this fits here as well as anywhere else.
People always ask how much it costs to heat up the pool (gas bill) so I thought I would share my experience.
We have heated our pool two times. The first was over Thanksgiving when the water temp was around 60Ã‚Â°F. I started the heater the morning of the day before. By that evening, it was already near temp and I was concerned about how big the gas bill would be so I shut off the heat for the evening. I restarted the heater the next morning and the pool was ready around 10:30am. The estimated cost was around $100-$120. That included heating the hot tub off and on that day as well.
The second time we heated was over spring break. We kept it heated for 5 days. I started it the night before about 7pm and the kids were swimming by 11am the next day. We had some bad weather that week so we could not swim each day. On the days we swam, I left the pump running and let the heater cycle off and on as needed. On the rainy days, I left the heater on, but left the pump on the timer so it only heated during the hours the pump was on - about 6 hours a day (3 in the morning and 3 in the evening).
We just got the gas bill and it looks like it cost less than $200 to heat it for the entire week.
So, it's not the sort of thing I'm going to do everyday, but at least it won't break the bank to do it once in a while.
I'll probably heat it one more time in about 2 weeks and hopefully that will be enough to carry us on into summer.
