Heater options for a Jupiter pool, side by side

The cheapest way to the full season in Jupiter

Solar panels + cover: 12 of 12 possible months for about $283 a year all-in, which works out near $47 for each month it adds.

Before you pay for any heater, buy a solar cover: on its own it adds 2 months here for about $50 a year (why a cover comes first). If you get quotes, ask for a heat pump sized to your pool's surface area; here it beats gas all-in (heat pump or gas).
