We live in Michigan and are hoping to extend the outdoor season for distanced socialization for us and our kids (with others). We've bought two propane heaters for the backyard, and are hoping to find heaters for the covered porch on the front of our house - it extends across the house and we can fit 3-4 people out there with 6' distancing. I cannot figure out what type of heat to use out there. A few space heaters on the ground? Infrared heaters on the ceiling? Something else? Any experience or tips? Nothing seems to be rated well.
