Will 4,000 BTU heat my garage?

Only a small, well-insulated space of about 100 sq ft, and mainly the area in front of it. Below freezing it takes the chill off rather than warming the whole garage.

Does it need electricity?

No. It runs on a 1 lb propane cylinder, which is why it suits tents, garages and outages. Some models offer an optional fan or blower that does need power.

Can I use it indoors?

Only in a ventilated area. It is a combustion heater, so keep a window or door cracked and never use it in a sealed bedroom or while sleeping.

How long does a 1 lb cylinder last?

Roughly a few hours on high, longer on low. Expect to swap cylinders often if you run it continuously.

Can I connect it to a larger propane tank?

Only with a hose and regulator rated for the heater; check the manual first. Many small radiant models are designed for disposable cylinders only.

Does it have a tip-over shutoff or thermostat?

Many basic models have neither, just a knob and an on/off valve. Check the specific model if safety shutoffs and adjustable heat matter to you.

Our take on the 4,000 BTU Portable Propane Radiant Space Heater

A small radiant heater that runs on a 1 lb propane cylinder and puts out 4,000 BTU, enough to take the chill off roughly 100 sq ft. Radiant heat warms people and objects directly rather than blowing hot air, so it works in a garage, tent, ice-fishing shelter or patio corner where there is no outlet. It is far less powerful than 9,000 to 30,000 BTU tank-top and cabinet propane heaters, and it needs ventilation because it burns fuel indoors. Owners value the instant, directional warmth and the no-electricity setup; the common complaints are the cost of disposable cylinders and the limited reach in cold weather.

Cons

Heats surfaces and people more than the whole room's air
No thermostat, timer or tip-over shutoff on many models
