Is this heat pump worth it over a gas heater?

If you have 240V power and a mild climate, yes. A COP of 6 means far lower running costs than propane or natural gas, though the upfront price is higher.

What size pool will 140,000 BTU heat?

Hayward rates it for roughly 1,500 gallons, so it suits small to mid-size in-ground pools. Larger pools need a bigger unit.

Does it work with salt water pools?

Yes. The titanium heat exchanger and Ultra Gold coating are built to resist salt water and pool chemicals.

What electrical service does it need?

A dedicated 240V circuit at about 30 amps continuous, roughly 7.2 kW. Confirm your panel capacity before buying.

Will it heat the pool in cold weather?

It works best in mild air, which is why Hayward recommends it for coastal areas. Output drops as air temperature falls.

What comes in the box?

The heat pump unit itself. Plumbing and electrical connections are installed separately by you or your installer.
