Abstract: The invention is, in one aspect, a system for heating or cooling a room, including a radiant panel with fluid conduit, which, radiates energy to a room. A heat exchange device exchanges energy between the fluid in the radiant panel and an exchange medium. A vent allows fresh air to enter a room, moved by a fan. The fan propels the air through a chamber for heating or cooling the air, wherein the chamber at least partially comprises the radiant panel.

Abstract: The invention is an apparatus for heating or cooling a room of a building. The apparatus includes a radiant panel supported on a wall, which radiates energy to or from a room. The radiant panel has a conduit for passage of a fluid. The invention also includes a heat exchange device which heats or cools the fluid, which is installed inside the wall between two studs. A first line and second line connect the inlet and outlet to the heat exchange device. A pump that pumps the fluid that is heated or cooled by the heat exchange, whereby the room is heated or cooled depending on whether the fluid is heated or cooled by the heat exchange device.

Abstract: An apparatus for heating or cooling a room of a building with an exterior wall includes a radiant panel supported on an exterior wall, which includes a fluid conduit for passage of a fluid. The fluid enters through an inlet and exits through an outlet of the radiant panel and goes through a transmission tube and into a heat exchanger, which is located on the exterior side of the wall. The fluid then flows through the transmission tube and enters the inlet of the radiant panel.
