An illustrated view of an exemplary pool heater device for providing heating of water for a swimming pool is presented. The pool heater device is useful for providing a quick and almost instantaneous heating of the water for a swimming pool. The pool heater device further has a quick and easy installation and can be installed on any swimming pool of any size. The pool heater device is portable and can be installed by an owner of the swimming pool without help of others.

Systems and methods are directed to water heater systems, including combi boilers and instantaneous water heaters, for initiating off-cycle purge operations, e.g., for energy reductions and efficiency means. Embodiments of the present invention can include at least one heat exchanger configured to heat water, at least one temperature sensor measuring water temperature at one or more locations within the heater system, and a control system in communication with the at least one heat exchanger. The control system can be configured to at least: determine an expected flow demand for hot water; monitor water temperature at an outlet of the at least one heat exchanger, initiate a burner sequence when the outlet temperature is greater than a delivery target temperature, and initiate a purge sequence when the when the outlet temperature is greater than a threshold temperature.

A heat pump for a pool or spa may include a human-machine interface (HMI). The HMI of the heat pump may be movable relative to a housing or body of the heat pump such that regardless of the location and orientation of the installation of the body of the heat pump, the HMI may be positioned so that it is accessible to a user. A heat pump may additionally or alternatively include means for managing condensate created by operation of said heat pump.

Exemplary embodiments are directed to swimming pool heat exchangers including a housing and one or more tube assemblies disposed within the housing. Each of the tube assemblies includes an elongated titanium tube and at least one fin welded to an outer surface of the elongated titanium tube. The elongated titanium tube and the at least one welded fin allow for corrosion resistance to swimming pool water while simultaneously allowing for improved heat transfer from the heat exchanger to the swimming pool water.

The present disclosure provides a cap and a water-heating device having the same. The cap for covering a top side of a case of the water-heating device includes a cover having a receiving space that is open at the bottom, the cover including an exhaust hole formed therein for releasing exhaust gas in the case to the outside, and an exhaust duct that is received in the receiving space and coupled to the cover and that forms an exhaust channel that connects an exhaust tube included in the case and the exhaust hole and releases the exhaust gas, in which the exhaust duct is formed of a material different from a material of the cover, and the material of the exhaust duct has higher heat resistance than the material of the cover.

The present disclosure discloses an ignition temperature control apparatus of a gas water heater, comprising: a heat exchanger made of stainless steel; a combustion device which supplies high-temperature flue gas to the heat exchanger; a water passage communicated with the heat exchanger; a first temperature detection device provided on the heat exchanger or on the water passage; a controller, wherein if a temperature detected by the first temperature detection device is lower than or equal to a first preset temperature or a rate of decline of a temperature detected by the first temperature detection device is higher than or equal to a first preset value the controller controls the combustion device to operate in such a state that a requirement for thermal bearing capacity of the heat exchanger made of stainless steel is satisfied. The heat exchanger of the ignition temperature control apparatus of the gas water heater of the present disclosure, which is made of stainless steel, has good thermal inertia and excellent thermal insulation properties, and thus the combustion device is started for heating when the ignition temperature control apparatus of the gas water heater is in a stop state, such that it is possible to ensure that the heat exchanger will not fail while an anti-freezing effect can be achieved.

A portable thermoshapable fabric composite heating device kit mainly comprises a portable heating device and a thermoshapable fabric composite; wherein the portable heating device includes a first box body and a second box body disposed above or inside the first box body. A heating space formed between the bottoms of the two box body bodies is used to accommodate a heating pack. The thermoshapable fabric composite can be accommodated within a receiving space of the second box body. After water is added into the first box body to flood the heating pack, and a lid is placed to cover the top, the heat-generating material in the heating pack contacts the water to generate water vapor during an exothermic reaction. The water vapor enters the receiving space, in which the thermoshapable fabric composite is stored, through the multiple pores at the bottom of the second box body. The generated thermal energy will heat the thermoshapable fabric composite without the need for open flame or electricity. That is, the thermoshapable fabric composite can be heated and softened, so that the thermoshapable fabric composite can be used in the field without reliance on external elements, such as conventional heating or electricity, in order to achieve the purpose of providing first aid such as bandaging and fixation, and to prevent secondary injuries.

A surgical fluid thermal treatment system can be used during a procedure to heat or cool surgical fluid, e.g., prior to introducing the fluid into the body of a patient. In some examples, the system includes an open basin into which fresh surgical fluid is dispensed and a heater that heats the fluid in the basin. The system may also include a volume measurement device that measures the volume of fluid in the basin. The system may have a user interface that a user interacts with to check fresh fluid into the basin. The user may also interact with the user interface to check medical tools into the basin and check medical tools out of the basin. A controller associated with the system can track the volume of fluid removed from the basin during the course of a procedure.

The present invention comprises a system for the localized heating of a portion of water within larger water bodies through a partial confinement of said portion of water without completely interrupting the water flow and where the concept of being in the same water body is maintained, in order to facilitate the practice of recreational activities in a heated environment. The present invention provides a solution to achieve a comfortable temperature of the water for direct contact recreational purposes in a cost-efficient manner, with a partial confinement system that allows creating a heat plug and provides for a serpentine-type flow between both sides of the partial confinement system.
