Natural gas space heaters sold at Lowe's allow homeowners to heat single rooms without installing expensive systems. However, these systems are less efficient than central heating options and may pose safety risks.
Unvented natural gas space heaters use efficient combustion to reduce the amount of carbon monoxide and other chemicals produced. Newer units can also detect inefficient combustion. However, malfunctions can still cause inefficient combustion to generate dangerous chemicals. While Lowe's also sells vented space heaters, extending a central heating system or installing better insulation can eliminate the need for space heaters. Homeowners looking to heat a garage, a shed or another small space may prefer the simplicity of gas-fueled space heating.
