Heaters with a built-in thermostat allow you to control the temperature. On heaters controlled with a knob, turn the knob to adjust heat output.
Style A heaters use convection to circulate warm air. They have a pilot light ignition and do not require electricity.
Style B heaters have an electronic spark ignition and are good for drafty areas where a pilot light could be extinguished.
