System for heating and cooling a room with insulating layer

A system for heating, cooling, or both heating and cooling a room comprising:

• a panel comprising:
• a first wall,
• a second wall, and
• a third wall,
• wherein the second wall is disposed between the first wall and third wall and the second wall is separated by a plurality of partitions from the first wall and from the third wall,
• wherein the partitions create a first and second row of elongated channels, wherein each channel in the first row is bounded on two sides by two of the plurality of partitions and on two other sides by the first and second walls, and
• wherein each channel in the second row is bounded on two sides by two of the plurality of partitions and on two other sides by the second and third walls;
• wherein the first row of channels is a fluid layer configured to allow heated or cooled fluid to pass through in a serpentine fashion, the fluid layer being in thermal communication with the room;
• and
• wherein the second row of channels is an insulating vacuum layer, with a reduced pressure that is at least 20% less than atmospheric pressure.
