How much space will 50,000 BTU heat?

In a well-insulated garage it can take the chill off a two- to three-car space, and it works best as spot heat aimed at where people are standing. In a cold, drafty warehouse it will warm the area in front of it rather than the whole building.

Does it need electricity?

Yes. The fan and ignition run on 120V, so you need a standard outlet or a generator. The propane supplies the flame, not the power.

Can I use it indoors?

Only in ventilated spaces such as garages, workshops and jobsites. Propane forced-air heaters produce carbon monoxide, so never run one in a sealed bedroom or living area.

Is a propane tank included?

Usually not. Plan on a standard propane cylinder and the correct hose and regulator for this unit. Check the listing for what comes in the box before you buy.

Does it have a thermostat?

This model is a simple on/off heater without a built-in thermostat. You control the heat by turning it on and off or by adjusting the tank valve.

How does it compare with a 30,000 BTU heater?

It puts out noticeably more heat and covers larger or colder spaces, but it burns propane faster and is louder. A smaller unit is easier to live with in a one-car garage.
