How much space will 45,000 BTU heat?

As a rough guide, 45,000 BTU can take the chill off a two- to three-car garage or a similar open work area. Actual coverage depends on insulation, outside temperature and how open the space is.

Does it need electricity?

Yes. Forced-air propane heaters use a small fan and ignition, so you need a power outlet or generator nearby. The propane supplies the heat; the fan moves it.

Can I use it indoors?

Only in a ventilated space such as a garage or job site. Propane forced-air heaters produce carbon monoxide and water vapor, so never run one in a sealed room or living area.

What propane tank does it use?

It connects to a standard refillable propane cylinder with the matching hose and regulator. A larger tank gives longer run time between refills.

How is it different from a radiant heater?

A forced-air heater warms the air and pushes it across the room, which heats a space faster. Radiant heaters warm people and objects directly and are quieter but more directional.
