Pool covers: heat, safety and fewer leaves
A cover is the highest-return accessory a pool can have: it halves heating costs, keeps debris out and can add real safety.

Why covers pay for themselves
An uncovered pool loses most of its heat through evaporation — covering it at night cuts heating energy by 50–70%. The same lid keeps out leaves and dust (less filtering, fewer chemicals) and slows water loss. Whatever else you economize on, don't skip the cover.
Solar blankets: the cheap workhorse
The bubble-foil solar blanket floats on the surface, warms the water a few degrees and blocks evaporation. It costs little, lasts 3–5 seasons, and its only sin is handling — get a roller station or it will never be used. Best for budget builds and rectangular pools.
Slatted automatic covers: the premium standard
Rigid PVC or polycarbonate slats roll out at the push of a button from a pit or bench. They insulate well, look intentional, carry some safety value and make daily covering effortless — which means it actually happens. They want a rectangular-ish pool and add a real line to the budget.
Safety and winter covers
Bar-supported safety covers and tensioned mesh winter covers protect children and pets and hold debris through the off-season. If small children live with or visit you, a certified safety cover (or fencing) is not optional equipment — treat it as part of the pool.
Frequently asked questions
- How much does a cover save on heating?
- Covering at night typically cuts heating energy in half, because evaporation — the biggest heat loss — stops.
- Do automatic covers work on curved pools?
- Slatted covers want straight, parallel walls. Free-form pools use floating blankets or custom tensioned covers instead.
- Is a cover a legal safety device?
- Only certified safety covers are. A solar blanket is not a safety device — a child can slip under it.
