Patent number: 8447176Abstract: A space heater and a method for generating a convection flow of air through chimneys of the space heater for heating an area adjoining the space heater is provided. The space heater includes a first panel, a second panel, and an element having one or more heatable surfaces. The second panel is coupled to the first panel and the element is located therebetween to define the chimneys between the first panel and the second panel. The element has the one or more heatable surfaces located within the chimneys. When activated, the one or more heatable surfaces create thermal energy for generating heated air within the chimneys, the heated air flowing by convection substantially upwardly through the chimneys to provide the heated air to the area adjoining the space heater.Type: GrantFiled: October 8, 2009Date of Patent: May 21, 2013Inventor: Mark J. McCourt

Publication number: 20130032308Abstract: A method of heating or cooling a room of a building includes providing supplemental warmer or cooler air to the room with an inline duct supplemental heating and cooling device mounted along an air duct that supplies the room with air from a main furnace or cooling unit associated with the building. A thermostat is used to set a desired temperature for the room, and a controller of the supplemental heating and cooling device is in communication with the thermostat, and activates an electric heater and/or fan as appropriate to warm or cool the room as needed. When the device is used to cool the room, the fan may be operated to draw cooled air through the duct from the main cooling unit and/or from other areas in the building that are linked via ductwork.Type: ApplicationFiled: October 8, 2012Publication date: February 7, 2013Applicant: TPI CORPORATIONInventor: TPI CORPORATION

Patent number: 8362406Abstract: An electric heater, comprises a heating block held in a housing and including parallel layers of heat-emitting and heat generating elements. A grid arrangement covers the respective frame apertures in the housing and reinforces the housing. First struts of the grid arrangement, extending at right angles with respect to the layers, are assigned to the housing, and second struts extending parallel with respect to the layers are defined by the heating block. Moreover, a heat generating element of an electric heater, comprises a position frame made of an insulating material and defining receptacles arranged side by side each for at least one PTC heating element. The receptacles are arranged between conductor paths against which the PTC heating elements are placed in an electrically conductive manner.Type: GrantFiled: July 17, 2008Date of Patent: January 29, 2013Assignee: Catem GmbH & Co. KGInventors: Franz Bohlender, Michael Niederer, Michael Zeyen, Rainer Wuenstel, Detlef Stephan
