There can be 3-4 days in a row without anyone in my family using my pool as we are at school and work and in the evening the kids have their organized activities( soccer, gymnastics,etc). I have been in the habit of simply turning off the heater for days on end as natural gas is getting costly.
Now the kids are off school and will be around much much more. We live in southern Ontario (Canada) and so far, summer temperatures suck!!!!!!!
We keep our pool at 84 F. At the end of the day, I turn off the heater for the night. In the morning the pool can drop to as low as 74 F. My 266k BTU heater is over sized for the pool so it gets back up to 84 F fairly quick. Nice and comfortable for the late morning and into the evening.
Pool store installed a new Pentair Superflo VS pump and they had it set to at an rpm high enough to filter and heat over night. They suggested it is more efficient to maintain the water temp overnight despite plunging air temperature than bringing the water up 10+ degrees all in one shot.
No doubt, it is a cost savings to shut off the heater for days on end when not in use, but for regular use what experiences do you have?
Run heater over night or just when needed?
I do not use a blanket at night for several reasons (awkward shape pool, expense of the roller, not wanting to fight with one every day, etc)
