Devices and methods for outdoor heating. A stove device includes a fuel system attached to a combustion chamber to deliver fuel from a hopper of the fuel system to the combustion chamber for combustion in a firepot assembly positioned inside the combustion chamber. A distance between a chute of the fuel system and the firepot assembly is adjustable to change an amount of fuel for combustion and thereby control temperature of combustion. The distance may be decreased to decrease the temperature and may be increased to increase the temperature

This application relates to a method for controlling the combustion in furnace systems, wherein an oxygen coefficient is determined from the temperature in a combustion chamber area and/or in the waste-gas flues of the furnace system and on the basis of an energy balance of the combustion process in the furnace system, the combustion air and the waste gas, and said oxygen coefficient is used to control the combustion material flows and therefore the thermal output and also the combustion quality. The invention relates to a device for feeding combustion air in the furnace system, which device has a chamber, which on a first side has a main duct for feeding ambient air and/or air from the chimney system and on a second side has a pane-washing air duct and a secondary-air duct, both the pane-washing air duct and the secondary-air duct.

A toaster oven includes a housing having an internal heating compartment, at least one heating element within the internal heating compartment, a vent associated with at least one wall of the internal heating compartment, the vent being moveable between an open position where air is permitted to pass into the internal heating compartment through the vent, and a closed position where passage of air into the internal heating compartment through the vent is inhibited. The vent is configured to move from the closed position to the open position in response to a biasing force exerted by a food support tray received within the internal heating compartment.

A microprocessor-based controller for pellet burners is disclosed that provides a level of safety and reliability to any pellet burner by implementing a feed forward control scheme using sensor detected information in a formula to determine proper processing results, utilizing feedback for proper combustion, such that temperature is effectively controlled, thereby greatly reducing the chance of a fire or an explosion.

A rope is used as a combustible material in a heating system, the rope comprising or consisting of fibrous plant material. Also, a method of operating a heating system comprises feeding a combustible material to a combustion chamber of the heating system, the combustible material being a rope of fibrous plant material.

A wood stove monitoring and control device can include a mounting flange mountable to a chimney exhaust pipe of a wood stove. The device can include a ring removably mountable on top of the mounting flange, where the flange is suitably positioned vertically along the exhaust pipe so that the ring is positioned at least partially above an end of the exhaust pipe. The device includes an optical beam source disposed on the ring, and which generates and outputs an optical beam. The device includes an optical sensor positioned on the ring opposite the optical beam source to detect the optical beam output by the optical beam source as the optical beam passes through smoke exhausted by the wood stove through the exhaust pipe. The device can include a temperature probe disposed on the ring to measure a temperature of heat exhausted by the wood stove through the exhaust pipe.

Pellet grills including a control system that implements, manages, and/or controls various ignition-based protocols and/or processes are disclosed. An example pellet grill includes a cooking chamber, a burn pot, an ignitor, and a controller. The ignitor extends into the burn pot and is configured to ignite pellet fuel located within the burn pot. The controller is configured to command the ignitor to activate during a first duration. The controller is further configured to determine, following expiration of the first duration, whether a temperature of the cooking chamber has reached a threshold temperature. The controller is further configured, in response to determining that the temperature has not reached the threshold temperature, to command the ignitor to activate during a second duration.

The present disclosure describes a chimney vent cap for controlling the flow of exhaust gases exiting a vent stack or chimney of a grill, cooker, smoker, or other device. The chimney vent cap is adapted to receive and reside about the vent stack or chimney and is configurable in multiple configurations using single plane movement and absent insertion of a user's hand into the exhaust gases, with each configuration corresponding to a particular flow rate of exhaust gases through the chimney vent cap and, hence, through the vent stack or chimney. The chimney vent cap is adapted to retain such configuration absent user intervention during movement of the vent stack or chimney caused by opening and closing of the lid or top of such grill, cooker, smoker, or other device, such that the flow rate of exhaust gases after such movement is substantially the same as prior to such movement.

A stove for indoor use includes a housing having a bottom wall, a top wall and one or more side walls defining a combustion chamber adapted to retain a fire, and an air supply system for supplying air to the combustion chamber. The air supply system includes a primary air conduit for supplying air to the combustion chamber from below through the bottom wall and a secondary air conduit for supplying air to the combustion chamber from above. A valve is arranged in the primary air conduit or in a branching between the primary and secondary air conduits. The valve is controlled by a bimetal whereby the valve is in a maximum open position when the prevailing temperature is below a first predetermined temperature during start-up of a fire and in a maximum closed position when the prevailing temperature is above a second predetermined temperature after start-up of the fire.
