Originally, we had several of those made as battery type brooders. They are the brooders that are like condominiums. Space saver, yes. But, hard to clean among other things.
At the farm, we do litter type (on the floor) brooding, inside the poultry building....that works best for us.
The battery types are kept for emergency brooding, or works well as isolation pens for chickens and even piglets......and is a seedling nursery, safe from predators ;)
