Embodiments of the invention provide a pool heater including a housing, a first tankless heater, a second tankless heater, and a controller. The controller is configured to activate only the first tankless heater when a first condition is met, activate only the second tankless heater when a second condition is met, and activate the first and the second tankless heaters simultaneously when a third condition is met.

A control system suitable for use with a bathing unit system having a water receptacle is provided. The control system comprises first and second heating modules and a controller configured for activating a specific one of the first and second heating module at least in part based on whether the bathing unit is in use.

An interactive health, beauty, wellness, and lifestyle tablet device and steamer having a housing and a water basin coupled to the housing. The device can further include a fluid atomizer coupled to the housing, configured to atomize fluid from the water basin, and an interactive display coupled to the housing. Here, the interactive display is configured to receive input from a user. In addition, the housing can also include a lighting unit disposed around the interactive display, and also a heating or cooling element disposed therein. The housing of the device may also include a receptacle for receiving a capsule or container and a tube for releasing and dispensing the contents of the capsule or container, among other features.

A therapeutic nanoparticle diffusion system includes at least one rubber bootie; a foot bath; and a nanoparticle composition. The rubber bootie is adapted to accommodate a user's foot and the nanoparticle composition. The foot bath has a predetermined height, a vibrational base, and a heating element attached. A therapeutic method of administering nanoparticles includes providing the bootie and the foot bath; adding water to the foot bath; donning the bootie; resting the foot and the bootie in the foot bath; adding a nanoparticle composition to the bootie; activating the heating element and the vibration element; resting the subject's foot in the nanoparticle composition; doffing and emptying the bootie into the foot bath; and soaking the subject's foot in the foot bath. The temperatures and times are predetermined.

Provided is a method for treating metastatic disease or any other tumor that cannot easily or readily localized or localized at all using immersion mechanotherapy. The method includes providing a vessel containing an amount of medium for immersing at least a portion of a subject, and applying one or more programmed cycles of ultrasound waves to the subject through the medium for a pre-determined period of time. Also provided is a device for implementing the immersion mechanotherapy.

The present invention is directed to methods and apparatus for tempering the temperature of a liquid in a fluid conducting system. More particularly, the invention relates to tempering the temperature of water supplied to a fixture from a water heater in a fluid conducting system.

A system and methods of remotely monitoring and controlling a pool controller for a pool or a spa via one or more remote computing devices is provided. In some embodiments, a remote user can be provided with information about the pool or the spa. The remote user is provided with an ability to remotely optimize a performance of the pool or the spa, including remotely adjusting a chemistry of the pool or the spa, remotely activating a heater of the pool or the spa, and/or remotely activating a pump of the pool or the spa.

A method, apparatus and system to facilitate maintenance of a network enabled bathing unit system. A Graphical User Interface (GUI) is presented providing a user operable control for receiving from a customer a service request requesting that a technician contact the customer. The user operable control may in some cases be enabled in response to detection of an operational error in the bathing unit system and disabled otherwise. In response to receipt of the service request through the user operable control, a notification message indicating that the customer has requested to be contacted by a technician is sent over a communication network. In some embodiments, a message responsive to the service request is received to cause the GUI to present user-selectable options to enable the customer to selectively permit the remote control and monitoring of the bathing unit system by a specific remote service technician.

A heating device is well-functioning, easy to install, aesthetically pleasing and convenient to use at the same time. It includes a frame having an upper face, which connects the rear and front faces and which generally has a step-shaped shape having at least two levels, which, in use, are at different respective heights and the highest level of which opens onto the rear face while the other levels are distributed substantially uniformly between a base of the frame and the highest level, such that, in use, a user may access the pool by successively walking on the levels of the step-shaped shape by climbing the levels from the ground to enter the pool and by descending the levels to the ground to leave the pool. The device also includes an air-water heat pump, arranged in an internal volume of the frame, which is defined between the base and the rear.

A liner for use with a basin to contain a liquid features a plurality of bodies of flexible plastic. Portions of an inner face of a first body of flexible plastic are joined to corresponding portions of an inner face of a second body of flexible plastic, through which a plurality of openings are formed, to provide a multi-layer body of flexible plastic. Other portions of the inner face of the first body of flexible plastic are not joined to corresponding other portions of the inner face of the second body of flexible plastic, defining an air conduit between the first body of flexible plastic and the second body of flexible plastic for guiding pressurized air substantially from an air discharge apparatus.
