An electrically conductive brickwork module configured to be used in an electrically heated thermal energy storage system and/or a resistive heating system to heat a fluid flowing across a dimension of the electrically conductive brickwork module from an input to an output. The module includes a plurality of electrically interconnected sets of electrically conductive bricks configured to be heated when electricity flows there through and a plurality of electrically insulating bricks separating each pair of adjacent sets of the plurality of electrically interconnected sets. There are and a plurality of flow paths defined by the plurality of electrically insulating and physically separated from the electrically conductive bricks to direct a fluid flowing from the input to the output.

A column-conditioning enclosure includes a column chamber adapted to hold one or more chromatography separation columns. A duct system provides an airflow path around the column chamber such that the one or more chromatography separation columns held within the column chamber are isolated from the airflow path. An air mover disposed in the airflow path generates a flow of air within the duct system. A heat exchanger system disposed in the airflow path near the air to exchange heat with the air as the air flows past the heat exchanger system. The air circulates through the duct system around the column chamber, convectively exchanging heat with the column chamber to produce a thermally conditioned environment for the one or more chromatography separation columns held within the column chamber.

A sand-based thermal storage apparatus, and a related system and method for heating a building are provided. The apparatus comprises an outer vessel, an inner vessel, a particulate heat storage material, and an electric heater. An annular interwall air space is defined between a wall of the outer vessel and a wall of the inner vessel, and surrounds the inner vessel. The interwall air space is in fluid communication with an outer vessel inlet and an outer vessel outlet. The particulate heat storage material comprises sand and is disposed in the inner vessel interior space and in contact with the inner vessel wall. At least part of the electric heater is embedded in the particulate heat storage material.

A heated ceiling fan device is disclosed that enables users to enjoy the outdoor environment in cool temperatures. The heated ceiling fan device comprises a ceiling fan with at least one heating element positioned on the bottom surface of each fan blade. The heating element output can be controlled by a remote control to achieve a desired temperature while the fan rotates. In one embodiment, the heating element is comprised of an infrared bulb. The fan can also be comprised of a speaker that can wirelessly connect with a sound device. Additionally, the fan can comprise a camera for additional security. Finally, the fan can also include a plurality of mist nozzles for additional protection from outdoor insects while providing a pleasant aroma.
