Workshop Heating and Cooling

My shop: -20’6” x 20’6” with a 10’ ceiling. All perimeter walls, except 12’ of one wall attached to my house, are not insulated. -Garage door is a regular 2 car garage door that I added insulation to. Two kits needed for my door. -Garage door has wide weatherstripping attached to the outside. -Ceiling above is not insulated. My local climate: -I live in central Mississippi which is known to have a high annual precipitation level. -Mississippi also has a high average temperature. Previous heating: -Two 1500w electric radiant heaters. They couldn’t keep up with the space. -Two electric radiant heaters + a small propane Mr. Heater one plaque 4,000-9,000-BTU Indoor-Safe Portable Radiant Heater. This worked but didn’t burn as efficient as I had hoped and produced an odor that we could smell inside the house. Previous cooling: -Box fan. Even a steady breeze is still miserable in the high heat and humidity of the Southeast climate. Current setup: -QuietSide brand mini split
