Step 1
Consider the size of the space to be heated and buy an appropriate heater. A heater that is too large may produce too many pollutants for the location and be energy inefficient. Choose between an electric, gas or kerosene appliance. Electric heaters come in radiant and convection models. Radiant models heat the objects at which they are aimed but will not heat the room. Convection versions warm the air around them.

Step 2
Read the package to confirm the space heater meets the safety standards of an independent, nationally recognized testing laboratory.
-
Step 3
Choose an electric space heater with the following basic safety features: a guard around the heating element or flame area to keep clothing, pets and children from coming into contact with it and an automatic "tip-over" shut off switch and indicator lights for when the heater is plugged in or turned on. Some advanced heaters utilize proximity sensors that turn the temperature down when objects, people or animals get too close.

Step 4
Measure the length of an electric heater's cord to ensure it will reach your desired location without an extension cord. If you decide an extension cord is necessary, use a cord marked with #14 or #12 A WG which indicates a sufficient wire thickness.
-
Step 5
Buy a gas space heater that is vented or equipped with an oxygen depletion sensor. The sensor will shut off the heater if carbon monoxide emission reaches a dangerous level. Look for a vented heater with a ventilation gauge to shut off the heater if it is not venting properly.

Step 6
Purchase an electric or vented fuel-fired heater for use in a mobile home.
