摘要： A water heater comprising a tank to contain water to be heated and having a downwardly convex lower head. A flue extends upwardly through the tank and the lower end of the flue projects downwardly beyond the lower head. A burner having a substantially smaller cross-sectional area than the flue is located adjacent the lower end of the flue, and a locator interconnects the projecting lower end of the flue with the burner for precisely positioning the burner with relation to the flue. A layer of insulation is disposed on the outer surface of the convex lower head and extends radially inward to the projecting end of the flue.

摘要： A water heater adapted to be mounted on the rooftop of a building includes a substantially cylindrical tank having a horizontally-oriented longitudinal axis. A U-shaped flue tube has a burner end and an exhaust end, both ends being mounted in a head portion of the tank. The legs of the flue tube define a flue plane that is preferably angled 30°-60° with respect to vertical. An inlet tube and an outlet tube also extend through the head of the tank. The inlet tube is positioned at the bottom of the tank and has holes that open downwardly only; the outlet tube is positioned at the top of the tank and has holes that open upwardly only. The tank is weather-tightly enclosed by a cabinet. A base member of the cabinet is supported by a roof curb and supports the water tank. The base member includes a drain opening for draining water from the inside the cabinet to the sewage system of the building, and a water pipe opening through which extend a plurality of pipes communicating with the tank. A grommet weather-tightly seals the pipes with respect to the base member.

摘要： A gas burner for a water heater and comprising a base having central passage. Gas fuel is supplied to one end of the passage and an orifice is removably connected to the other end of the passage. An inverted cup-shaped head has an inner end threaded to the base and defines a closed chamber disposed in communication with the orifice. A plurality of ports are formed in the head and provide communication between the chamber and the exterior of the burner. The ports have a greater axial length than diameter and aid in controlling the flame configuration.

摘要： A water heater includes a water tank, a combustion chamber below the tank and communicating with the flue tube, and a flue system. The flue system includes a flue tube, and V-shaped fins that are metallurgically bonded to the flue tube wall to divide the flue tube into four flue chambers extending substantially parallel to the longitudinal axis of the flue tube. The V-shaped fins include radially extending apertures that reduce the thermal expansion of the V-shaped fins with respect to the flue tube to reduce stress at the joint between the fins and the flue tube. The flue system also includes a removable baffle hanging in each flue chamber. The baffles include adjustable turbulation surfaces to control the quality of combustion in the water heater.

摘要： A gas-fired water heater including a tank to contain water to be heated and a flue extends axially through the tank. A burner is located at the lower end of the flue and has a smaller cross sectional area than the flue to provide an annular space between the burner and the lower end of the flue. The burner has at least one outlet port that directs a flame pattern in proximate relation to the lower end of the flue. A locator assembly supports the burner from the flue and positions the burner axially of the flue.

摘要： A water heater includes a storage tank communicating with a cold water supply pipe and a hot water supply pipe for the respective supply of cold water to, and removal of hot water from, the tank. The water heater also includes an insulated heat recovery module communicating between the cold water supply pipe and the tank. The heat recovery module defines a cavity, and the cold water supply pipe communicates with a lower portion of the cavity. The heat recovery module has a smaller surface area-to-volume ratio than the cold water supply pipe. When water in the tank is heated, some water is thermally displaced from the tank and into the cavity. Consequently, water is displaced out of the lower portion of the cavity and into the cold water supply pipe. Therefore, only the coldest water is displaced out of the cavity, and thermal energy loss is reduced.
摘要翻译：热水器包括与冷水供给管连通的储罐和用于各自供给冷水的热水供给管和从罐中除去热水。热水器还包括在冷水供应管和罐之间连通的绝热热回收模块。热回收模块限定空腔，冷水供应管与空腔的下部连通。热回收模块具有比冷水供给管更小的表面积/体积比。当罐中的水被加热时，一些水从罐中热位移到空腔中。因此，水从空腔的下部移出并进入冷水供应管。因此，只有最冷的水从空腔中移出，并且减少热能损失。
