I just saw a photo of a floor heating system, and there aren’t many “straight” heating parts, it’s all curved. Why?

Heat transferrence depends on surface area. If you just have a block, the surface area is only the outer areas. If you cut that block, you get all the area on each side of the cut as well.
This is why heat sinks have all those fins.
For heating and cooling systems like you’ve described, they need to use coils because the heating medium is a liquid that needs to keep moving through the system to transfer the heat.
