Wall heaters save space while instantly taking a chill out of the air. Acting like the sunís rays, infrared models warm objects directly rather than surrounding air. That translates into energy efficiency and a more comfortable environment. Vent-free units with options for natural gas or propane include enhanced shut-off and oxygen depletion features for optimized safety in any indoor setting. Variable heat settings make these ideal for bathrooms, hobby spaces and even workshops. Before cold weather arrives, make a selection and be prepared.
