摘要： A water heater includes an inner water tube coil and an outer water tube coil separated by a drum baffle. The inner and outer coils extend above a top edge of the drum baffle by at least a full turn of each coil. A flue gas bypass path is defined between a top edge of the drum baffle and a top insulation layer above the inner and outer coils. Flue gases flow radially though the inner coil, up along the drum baffle, through the flue gas bypass path, and downwardly over the outer coil to heat water flowing through the inner and outer coils. The water flows into the outer coil at the bottom of the coil, winds upwardly through the outer coil in countercurrent flow with respect to the flue gases, then down through the inner coil.

摘要： The invention relates to a heating system component for a heating system for heating a fluid medium, with a carrier unit, and a heating unit coupled to said carrier unit, wherein said carrier unit comprises a wet side and a dry side, wherein said wet side corresponds to a surface of said carrier unit configured to be in contact with said fluid medium, wherein said dry side is located on a surface opposite to said wet side; and wherein said heating unit is recessed in a groove provided on said dry side of the carrier unit. A temperature sensor, in particular an NTC thermistor, positioned to measure a temperature of a fluid medium at the wet side of the carrier unit, wherein the temperature sensor is effectively thermally insulated from the heating unit.

摘要： A liquid heating apparatus includes a top portion with a burner unit, a coil, an external housing, and an internal housing. The burner unit is arranged to burn a fuel so as to generate a downward directed flame. The coil includes first and second layers of windings. The internal housing is arranged within the external housing. The apparatus is in a substantially upright position during operation. A compartment between the internal housing and the external serves as a first liquid reservoir. The flame from the burner unit is peripherally contained by an inner part of the first layer of windings of the coil. The first layer of windings is configured to direct the flame or exhaust gases downwards. The flame or exhaust gases are redirected such that the they contact all of the second layer of windings, the internal housing inner wall, and the first layer of windings

摘要： A water heater insert device positioned within an electrical showerhead or as a standalone liquids heating device. The water heater insert optimizes heat transfer by channeling water through a channel of a spiral or zigzag form where a deployed heating element supplies thermal energy. The channel maximizes water contact while minimizing the space. A temperature limiter adds protection against scalding.

摘要： A heating unit for a beverage preparation machine. The machine includes a pump for circulating a beverage preparation fluid through the machine from a fluid source to the heating unit. The heating unit is suitable for heating the fluid and includes a housing which defines a fluid heating chamber. A heating element is located inside the housing and is adapted to heat the fluid. The heating unit further includes a pre-heating tube for conveying the fluid from the pump. The pre-heating tube includes a tube inlet and a tube outlet. The tube outlet connects with the heating chamber. The pre-heating tube is located at least partly within the housing such that the heating element will at least partially heat the fluid in the pre-heating tube before the pre-heated fluid is released into the heating chamber through the outlet.
