摘要:
Apparatus and methods are provided for compensating for high altitude reduction in the heating capacity of a gas heating appliance, illustratively a gas-fired heating furnace. In a representative embodiment of such apparatus and methods the regulated pressure of the furnace gas valve, and the speeds of its combustion and indoor blowers, are coordinatingly increased to provide the furnace with a substantially unchanged maximum heating output despite its new higher altitude location.

A water heating system uses a heated fluid storage tank to deliver a continuous supply of water heated to a desired temperature, such as between 100null-130null F. The system also includes a furnace with altitude-sensitive control circuitry to provide multiple sources of heat for the heating system in the most effective way given the altitude at which the system is located. The system also includes a micro-controller that adjusts certain system components in response to changes in atmospheric pressure conditions that are measured by an atmospheric-pressure sensor component: There is also an automatic-air-bleeder subsystem with an optical or ultrasonic sensor mounted adjacent a suitable air accumulator. Also included is an air-release solenoid and a fuel return line.

A heat management system is capable of managing unlimited hydronic heat sources and unlimited heating zones, each located within a desired area and each controlled by temperature sensors. The system uses plural system heating sources to heat a heating solution (preferable glycol-based) that is either heated directly or through a liquid-to-liquid heat exchanger. The heating solution is passed through various plumbing configurations to heat domestic water for users and to heat zones or areas in which user will live. The heat management system of the invention may be used for several applications including RV, marine and home hot water and heating applications.
摘要:
An automatic device for controlling the supply of fuel to a heater which includes magnetic device units operatively associated with on/off switches, respectively, and a thermostat operatively connected to the switches, whereby one of the switches is actuated to the off position by the sensing of the thermostat for a period time of a higher room temperature than a predetermined thermostat temperature. Also, upon the off position of the source of electric power, the fuel supply automatically puts out the fire.
摘要:
A controller in a heat management system is capable of managing unlimited hydronic heat sources and unlimited heating zones, each located within a desired area and each controlled by temperature sensors in bi-directional electronic/electrical communication with the controller. A user interface can be included with the controller (or interact with the controller) and be in bi-directional electrical/electronic communication with the controller. In such a way, one or more users can manage the heating of domestic water and the heating of zones or areas in which the one or more users live via the controller. The controller in the heat management system may be used for controlling hydronic heating systems installed in RV, marine and home applications.

摘要:
An apparatus for extinguishing undesired flames in liquid fuel-burning heaters having a wick partially disposed in a fuel supply reservoir in fluid communication with a fuel tank said apparatus comprising fuel flow cut-off means for interrupting said fluid communication in response to sensing excessive heat and wick withdrawal means for retracting said wick entirely into said wick fuel supply reservoir in response to sensing of excessive heat.
