A study tested a heating and cooling system using pipes attached to insulating bricks. The system is affordable and easy to install, suitable for both old and new buildings. It works well without extra insulation, unlike other systems. The system responds quickly to changes in temperature, with a small difference between water and surface temperatures. However, surface temperatures can be uneven, so careful placement is important to avoid issues like condensation. Installing the system on multiple walls can create a more even temperature throughout a room.
