We have the heaters purchased for our patio to sit there in the evening in the autumn. It depends on the pavilion and thus heated a table with 4-6 chairs, so you can still sit warm and comfortable at temperatures of 12-14 degrees outside, even in a small round. The radiator has four stages, the highest level was too warm for us most and we have used it only at level 2 or 3, which is perfectly adequate. Depending on how and where to hang the radiator can heat a pretty large area so that's why I think he's perfect for patio or garden. He is also weatherproof and despite storm, rain and snow.
