Does it need electricity?

No. It runs on propane only, with no cord, battery or fan, so it works during outages and off-grid.

How long does a 1 lb cylinder last?

About 2 hours at full output. A larger tank with a hose adapter gives much longer run time.

Can I use it indoors?

It is sold for indoor and outdoor use, but any unvented propane heater needs ventilation and a carbon monoxide alarm. Follow the manual's clearance rules.

How much area does it heat?

It is rated for roughly 400 to 799 square feet, but radiant heat is directional. Expect it to warm people and objects in front of it, not a whole open room.

What safety features does it have?

It has a safety fuel shutoff, a tilt shutoff that cuts the gas if the unit is knocked over, and an exterior grate guard over the hot element.

Can I connect a larger propane tank?

Yes, with a hose and regulator for a 20 lb tank. That is the usual fix for the short run time on 1 lb cylinders.
