Abstract: Disclosed a control method for monitoring the efficiency status of the components of the primary circuit of a gas boiler, the components including the pump, the primary exchanger, and the secondary exchanger on the primary side. The method includes a first part “method M.dhw” suitable to signal that one of the components of the primary circuit is degraded, due to a drop in the flow rate Q circulating in the primary circuit. Said method further envisages a second part “method M.hea” (or, alternatively, “method M.hea.bis”), capable of indicating that the component of the primary circuit actually responsible for the degradation is either the secondary exchanger on the primary side or one of the pump and the primary exchanger.

Abstract: In an appliance, an input switch receives a knock input at the front of a main body, and a transfer member connecting to the input switch transfers vibrations cause by the knock to a sensor disposed at the rear of the main body. Thus, even an appliance such as an oven and the like that makes it difficult to attach a sensor to a door due to high-temperature heat effectively senses a knock input.

Abstract: A combination domestic hot water and space heating system is disclosed. The system includes two refrigerant circuits, one dedicated to heating potable water in a water storage tank and one dedicated to heating a condenser used to heat a space within a building. A controller sends output signals to valves to vary refrigerant flow into the first refrigerant circuit and/or the second refrigerant circuit. The variation in refrigerant flow can be provided by a single multi-directional valve, one or more valves placed at a first end of each refrigerant circuit, and/or one or more electronic expansion valves placed at the end of each refrigerant circuit. Portions of the system can be placed into a single housing, thereby reducing installation costs and labor.

Abstract: The claimed invention provides an eco-friendly alternative to traditional gas boilers, specifically the claimed invention provides a boiler that uses microwaves as a means to heat water within a boiler system. Preferably the water enters the boiler via one or more spray nozzles to produce a plurality of droplets or mist, which is then heated when they are exposed to the generated microwaves within the boiler.

Abstract: Subterranean thermal capacitance for an environmental-control apparatus mechanized via a solar thermal system. The method and apparatus use a solar collector and a plurality of heating-energy-storage cells that are each thermally insulated from one another, wherein heating energy-transfer fluid (HETF) coming from the solar collector is transferred to the energy-storage cell having the highest temperature that is greater than the temperature of the HETF, in order to segregate energy-storage cells to more efficiently store heating energy.

Abstract: Embodiments are disclosed of a radiator temperature control apparatus for controlling the heat output of a radiator. The radiator temperature control apparatus may include an airtight enclosure around the air outlet of the radiator air vent, an adjustable opening in the airtight enclosure controlled by an actuator, and a controller connected to the actuator. In operation, the controller can be configured to open the adjustable opening in the airtight enclosure allowing air in the radiator to be expelled through the adjustable opening, thereby allowing steam to enter the radiator, and heat the room. The controller can be configured to close the adjustable opening, stopping air from being expelled from the radiator, thereby stopping additional steam from entering the radiator.

By directing cleaning spray directly into the interior of the jet plates, cooking juices that fall through the slots and openings and into the air passageway of the jet plates can be pressure cleaned and drained from the interior of the jet plates without removing the jet plates from the oven cavity.

Abstract: A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.
