  • Publication number: 20190078772
    Abstract: Aspects of the invention provide a heat exchanger including a shell at least partially defining an interior region; a burner positioned to deliver combustion gases into the interior region; and a plurality of tubes configured to circulate water therein, the plurality of tubes extending through the interior region. The plurality of tubes further including an inner set of tubes and an outer set of tubes, the inner set of tubes being closer to the burner than the outer set of tubes. The inner set of tubes and the outer set of tubes being positioned adjacent to one another such that the outer set of tubes is staggered from the inner set of tubes and tubes of the outer set of tubes are adjacent to tubes of the inner set of tubes. Additionally, baffle segments are annularly positioned in the interior region adjacent the plurality of tubes. Adjacent baffle segments defining gaps for the flow of the combustion gases.

  • Publication number: 20170356674
    Abstract: Disclosed is an inventive water management header and method for making the same. The water management header is attached to a boiler or water heater. The water management header includes a cylindrical shell that at least partially defines an interior region. Inner and outer series of heat exchange tubes extend within the interior region of the shell from a lower end of the shell to an upper end of the shell. The header is capable of being configured to provide a unique fluid flow pattern through the boiler or water heater relative to another water heater or boiler of similar design via a waterway primary inlet, outlet, a plurality of crossovers and a plurality of barriers.

  • Patent number: 8851022
    Abstract: A water heating system includes a housing that defines a substantially enclosed interior region. A control panel is attached to the housing and includes a display that displays a particular condition of the water heating system. An access panel is attached to the housing for movement between a first position and a second position, wherein, in the first position of the access panel, a passageway to the interior region of the housing is provided, and, in the second position of the access panel, the passageway to the interior region of the housing is closed. The display is visible in both positions of the access panel such that movement of the access panel from the second position to the first position facilitates simultaneous access to the display and to the interior region of the housing though the passageway.

  • Patent number: 8838270
    Abstract: A data packet is provided that includes a synchronization field and an acknowledgement field indicative of an acknowledgement of receipt of a prior data packet. The data packet also includes a response field that includes information indicative of a system fault, a header field, and a sequence number field that includes a number assigned to the data packet. The data packet further includes a data field, an end of packet field, and an error-checking field. Methods and computer program products are provided that, in some implementations, include retransmitting packets if the acknowledgement field in a received data packet is a no acknowledgement (NAK) and/or placing a node into a safe state in response to a fault signal that is included in the received data packet.

  • Patent number: 7756036
    Abstract: Methods, apparatus, and computer program products that synchronously communicate data packets between a first node and a second node. Data packets are transmitted from the first node without waiting for acknowledgment of receipt by the second node. Acknowledgment of receipt of a given data packet is subsequently received at the first node. The acknowledgement is received substantially at a predetermined time following transmission of the given data packet. The acknowledgement indicates that the second node received the given data packet uncorrupted.
