Pool Cover Energy Savings Calculator
Pool covers cut evaporation 80-90%, reducing heating cost + water + chemicals.
Payback months
18.3
Annual savings
$2,300
Lifetime savings
$16,100
How the math works
Savings = heating + water + chemical. Payback = cost / savings.
$1,500 + $800 = $2,300/yr. $3,500 / $2,300 = 18.3 mo payback.
How to Use
- Enter pool surface sqft.
- Enter cover cost.
- Enter annual heating savings.
- Enter annual water + chemical savings.
- Enter useful life.
- Read payback.
Frequently Asked Questions
Pool cover types?
Solar cover (bubble): lightweight, cheap, DIY. $1-3/sqft. Life: 3-5 years. Safety cover (mesh or solid): heavy-duty, winter closure. $2-6/sqft. Life: 5-10 years. Automatic cover (motorized): premium, convenience. $5-20/sqft. Life: 8-15 years. Thermal/insulated blanket: mid-range. $3-8/sqft. Indoor pool covers: reduce humidity + heating.
Energy savings?
Evaporation is major heat loss mechanism. Cover reduces evaporation 70-90%. Heating savings: 30-70% of pool heating cost (indoor or outdoor heated). On $3,000 annual pool heating: $1,000-2,000 savings with cover. Hot/humid climates: savings larger (water evaporation higher). Cold climates: heating savings dominant. Outdoor year-round pool: largest total savings.
Water + chemical savings?
Water loss: 1-3 inches per week evaporation on outdoor heated pool = 30-90% water makeup. Cover reduces 50-80%. Chemical loss: chlorine evaporates with water. Reduced chlorine usage 30-50% with cover. Combined water + chemical savings: $500-3,000/year for mid-size pool. Plus reduced cleanup from leaves/debris.
Operational trade-offs?
Daily open/close: 5-30 minutes labor. Automatic covers: minimal labor. Swim area restriction: cover off during swim hours. Summer peak: cover on nights/weekends off-hours. Storage: some covers require reels ($500-3,000) for mechanical storage. Repair/replacement: manual cover tears, automatic cover motor failure ($500-3,000). Still strong ROI despite operational friction.
