How long will the Jackery HomePower 3000 run a space heater?

About 3.5 hours from a full charge. A space heater averages about 750 W (1,500 W running, on about 50% of the time), and the 3,072 Wh battery gives about 2,611 Wh after inverter losses. That is 29% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 2,100 W more of the 3,600 W output. Each thing you add shares the same battery, so the 3.5 hours for a space heater gets shorter.
