@LBCarpentry 1 every couple of meters will be fine and you will feel the benefit up to around 4 feet away. Just remember they don't heat the air but solid items. If you are working in a warm top and trousers then once you start working you will feel very comfy after a couple of minutes but the main benfit is you don't end up feeling too hot that you sweat. To preheat a surface for finish or glue about 18 inches is the best distance that I have found
4 foot is still pretty close. Don;t think wall mounting is an option in that case. Perhaps just painting them at the metal machines. Im convinced they act as an ice cube. Do you have any product recommendation?
