When to start heating your pool

[Lenny]

Do you get full sun all day?

I was thinking that I would need the heater in the early going to get the water temp to catch up with the warm weather but that I wouldn't need it much again until the fall.

You will need it at times all summer. An inground pool is different than an above ground pool. An above ground pool is surrounded by nice warm air in the summer on 5 sides and is only in contact with the ground on the bottom. An inground pool is in contact with cool soil on 5 sides and air on the surface only. Thus, even in the summer you will contantly loose heat to the ground, and if you don't cover it the cool night air will drain heat away as well.

There are many factors that go into the heat balance of the pool. Wind will cause a lot of evaporation which drains much heat, the cover helps prevent that. If you really don't want to use a cover there is a product called a fish or something like that which is some type of surfactant that claims to coat the water surface when the pool is not in use to minimize evaporative losses. I have no experience with it, but have heard it is better than nothing.

like you lenny we didn't want to go the solar cover way -- and we still don't. i agree with the poster who said it's kind of a personal decision on when you heat the pool.

the way i look at it is ... the pool is there for our enjoyment ... we rarely go out often for big nights on the town ... we like to be at home ... we don't eat out much because we enjoy being at home ... we enjoy having our friends over and always provide the food and booze because they made the effort to visit ... i love it when people have a great time at our place and i don't worry about the expense -- i want to enjoy as much of the "summer" as i can (we live at the southern tip of ontario, canada) ... if i have to spend an extra $100 per month to enjoy the water at the temperature i like, when i want, then i'm going to do it. we're not big spenders in general and i like the little bit of decadence heating it provides ... friends get a big kick out of swimming in a steaming pool on a cool night ... and we only do this a handful of times

having said all that ... during the cooler months, i only aim for the warm pool on weekends ... but man it's great!!!

one more thing ... regarding the fish ... i put them in during the spring and fall ... do they work ... i have no idea!!!
if they work, it's marginal ...

I do have one of those fish, sleater, and will give it a try soon. Thanks.

I get the feeling you enjoy your pool

You guys talked me into it . By the next warm weekend we'll have a heated pool.
