The present disclosure relates to a dishwasher in which a single heater bracket is used to support and fix a heater in a heater housing, thereby reducing flow resistance against dry airflow flowing in the heater housing and minimizing the generation of noise, and in which the heater bracket, and a supporting leg supporting the heater housing with respect to a base are fastened to the heater housing at the same time by a single fastener, thereby simplifying the inner structure of the heater housing and minimizing costs incurred for assembling and manufacturing a dry air supply part.

This heating system consists of a ceiling or wall mounted housing containing a fan, motor, electric heater and optional controller which connects to a discharge vent via a duct which can all fit within a wall. It has primary usages as a room or shower heater where it can be recessed into a wall or ceiling where it intakes air from the room, heats it and routes it through an insulated duct in the wall and vents it back into the room near the floor. In a shower, the heater can be located high on the wall or in the ceiling away from the shower to keep it away from splashed water. Additionally, the heater and vent can both be mounted in the ceiling where the heater is outside the shower and the vent is in the shower. It can be controlled by a switch, wired thermostat or wireless remote.

This invention relates to a heater. A combustion air blower feeds combustion air to a burner device. The burner device burns a gas-air mixture from the combustion air and a fuel and serves for heating air. A circulating air blower discharges heated air from the heater. A control device acts on at least one component of the heater, wherein a night mode parameter set associated with an operation of the heater in a night mode and a default parameter set are stored in a data storage device. After an activation of the night mode, the control device accesses the night mode parameter set and uses the same for acting on the component. The night mode parameter set effects a reduction of background noise generated by the heater.

The flameless heater system includes an energy source comprising a diesel engine configured to create volumes of air, a hydraulic system to control engine loading for heat generation and for air moving, and a control system, operatively coupled with the energy source and the hydraulic system to control at least one of a speed of the diesel engine, a loading of the diesel engine, or a fan speed.

A transfer tube for a thermal transfer device can include at least one wall having an inner surface and an outer surface, where the inner surface forms a cavity, where the at least one wall further has a first end and a second end. The first end can be configured to couple to a terminus of a heat exchanger of the thermal transfer device. The second end can be configured to couple to a collector box of the thermal transfer device. At least a portion of the at least one wall can be disposed in a vestibule of the thermal transfer device. The cavity can be configured to simultaneously receive a first fluid that flows from the first end to the second end and a second fluid that flows from the second end to the first end.
