20090025653 | Water heater and a method of operating same - A water heater ( | 01-29-2009 |
20090078218 | Water heater having temperature control system with thermostatically controlled mixing device - A kit, device and method for improving the hot water supply performance of a water heater are provided. The device comprises a fitting, a conduit, and a mixing device. The fitting includes an inlet port configured for coupling with a cold water supply line, an outlet port configured for releasably coupling with a cold water inlet port of the water heater, and a bypass port configured for diverting a portion of the cold water from the cold water supply line. The conduit includes an inlet port configured for coupling with the bypass port of the fitting and an outlet port. The mixing device includes a mixing port for coupling with the outlet port of the conduit, an inlet port for releasably coupling with a hot water outlet port of a water heater, and an outlet port for coupling with a hot water supply line. | 03-26-2009 |
20100300376 | BOILER PARTICULARLY FOR HUMIDIFIERS - A boiler particularly for humidifiers, provided with a tank, supported by supporting elements, which have a filling and discharging orifice. A centrifugal discharge pump is supported by the supporting elements in a position that faces the orifice, so that the axis of its impeller substantially coincides with the axis of the orifice. | 12-02-2010 |
20120103280 | VARIABLE FLOW HEATING SYSTEM WITH HEATING ACCESSORIES PLACED IN SERIES - Heating systems including a boiler for heating a heating fluid, a plurality of heating accessories each requiring input of heat, piping connecting the boiler with the heating accessories, at least one of the heating accessories being placed in series relative to at least one other of the heating accessories, and a valve system including a variable speed pump and an associated control system for varying flow of the heating fluid from the boiler. Each heating accessory is configured such that heating fluid from the boiler delivered through the piping to each successive heating accessory provides heat to each heating accessory and the heating fluid is returned to the boiler at a sufficiently low temperature (e.g., no more than about 120° F.) so as to allow the returned heating fluid to be used to condense water out of flue gas generated by the boiler so as to maximize the efficiency of the boiler. | 05-03-2012 |
20120227681 | PIPE CONNECTING STRUCTURE OF WATER HEATER - A pipe connecting structure of a water heater. Individual parts in the water heater are integrally coupled with a pipe body, which is injection-molded, provides paths of tap water and hot water, reduces the number of pipes connecting the individual parts, and simplifies the connection structure of the pipes. The pipe connecting structure of the water heater includes a tap water inlet pipe connected from a tap water inlet to a heat exchanger; a hot water supply pipe connected from the heat exchanger to a hot water outlet; a flow sensor for measuring the flow rate of the tap water introduced via the tap water inlet; and a flow control valve for controlling the flow rate of the hot water discharged via the hot water outlet. The pipe body connects and is integral with the tap water inlet, the tap water inlet pipe, the hot water supply pipe, and the hot water outlet. | 09-13-2012 |
20150316287 | DEVISE DESIGNED TO MAXIMIZE THE EFFICIENCY AND MINIMIZE THE CONSUMPTION OF BOTH, WATER AND ENERGY, IN THE UTILIZATION OF HOT WATER - This invention consists of a system to minimize the cost and consumption of energy and water for hot water users which comprises: (a) a storage tank, which has a plurality of chambers connected in series, arranged one above the other, each one with a water inlet/outlet contiguous to the adjacent chamber. Additionally, the tank also includes a water supply inlet and an outlet pipe for its provision of water at a given temperature to the required service (shower head, faucet, etc.); (b) solenoid valves on each of the cold and hot water supply lines, which are connected to the tank's first chamber; (c) an algebraic thermometer, placed in the first chamber, which detects the water temperature along the first chamber and sends an electric signal to a controller; and (d) a controller, which includes a dispenser (metering unit), as well as an electric signal input coming from the thermometer and an electric signal output that is sent to the hot and cold solenoid valves. | 11-05-2015 |
20150377498 | One-way Closed Pipeline Internal Circulation Apparatus - The present invention provides a one-way closed pipeline internal circulation apparatus, including a first water pump and a manifold conversion three-way joint, where an external interface of a secondary pipe of the manifold conversion three-way joint is connected to a water outlet port of the first water pump. When the apparatus is used with a conventional gas water heater, hot water will instantly flow out when a water tap is turned on, and through mixing and transition of a hot water mixing container, other gas water heaters installed have a characteristic of steady and uninterrupted flow of hot water, which not only improves comfort of a user, but also achieves the purpose of saving water resources. | 12-31-2015 |
20160084509 | WATER SAVING APPARATUS - A water saving apparatus for use with a hot water system, the apparatus being sized and shaped for installation proximate one or more water outlet fixtures for delivery of heated water from the hot water system for use. The apparatus comprises an insulated reservoir having an inlet and an outlet to enable the reservoir to be installed in line with the flow of heated water from the hot water system to the one or more fixtures to store a quantity of heated water. Water that has cooled in the hot water pipe between the hot water system and the reservoir mixes with the stored heated water in the reservoir as water flows from the hot water system to the water outlet fixture. | 03-24-2016 |
