A tankless water heater includes a heater assembly, a temperature sensor, a flow sensor, a first heating element, a second heating element, and a controller. The heater assembly includes a water inlet, a water outlet, and a heating chamber defining a water flow path between the water inlet and the water outlet. The temperature sensor measures the temperature of water flowing through the heating chamber. The flow sensor measures a flow condition of water within the heating chamber. The first and second heating elements are located in the heating chamber and include first and second wattages, respectively. The second wattage is different from the first wattage. The controller is coupled to the first and second heating elements and the temperature and flow sensors. The controller is configured to regulate the amount of electrical current flowing through the first and second heating elements in response to the flow condition.

A vehicle glass removal system and method using a heating element and thermoplastic adhesive is disclosed, whereby a resistance heating element is deployed along the bond line between a vehicle glass member and its supporting vehicle frame. The system accepts user input and activates the heating element, causing the adhesive along the bond line to weaken, thereby reducing or completely eliminating the need for a cutting operation when separating the glass from the frame. Two embodiments are contemplated for the deployment of the heating element: embedded within the perimeter of the glass member, or preferably deployed along the vehicle window frame. The system includes safety precautions that prevent the heating element from operating while the vehicle is in operation, including authenticated access and communication with the vehicle electrical system to recognize the state of the vehicle.

The invention relates to a heating system for heating a living being, for instance, a person (2) within a vehicle (1) being preferentially a hybrid car or an electric car. The heating system comprises an infrared laser system (5, 6) for illuminating the living being with infrared laser light, thereby heating the living being. Thus, heating radiation is used, which has a high collimation and which can be focused relatively easily. The heating can therefore be confined to a certain region, in which the living being is located. The heating can even be confined to the living being or to parts of the living being only. This more focused heating allows for a reduction of the energy consumption.

A sublimation device includes a first heater and a second heater. The first heater includes a proximal end, a distal end, and an inner surface. The distal end is disposed opposite the proximal end. The inner surface extends between the proximal end and the distal end and at least partially forms a cavity. The second heater is disposed proximate the distal end of the first heater.

A television/space heater combination device for displaying image content and for heating air and method of using the same is presented. The television/space heater combination device includes a television, a space heater and, sometimes, a frame. The method of use includes activating the space heater; selecting a temperature value for the space heater; generating heat and distributing the same into a room from the space heater; activating the television; and displaying an image on a screen of the television while generating heat with the space heater. The displayed image may be an image of a wood or gas burning fireplace generated by a continuous video loop; or be images from regular television programming or images generated by data transmitted to the television by a remote computer.
