  • SYSTEMS AND METHODS FOR PRE-HEATING SWIMMING POOLS OR SPAS
    Publication number: 20230280070
    Abstract: A heating system for a pool or spa includes at least one heating device and a controller. The controller may control and/or operate the at least one heating device in a pre-heat mode or a usage mode. The pre-heat mode may heat water of the pool or spa to a pre-heat temperature based on a first input received by the controller. The usage mode may heat the water to a set temperature greater than the pre-heat temperature based on a second input received by the controller after the first input.

  • HYBRID HEATER FOR POOLS AND SPAS
    Publication number: 20230213238
    Abstract: A swimming pool or spa may include hybrid heater. The hybrid heater includes an enclosure, a first heat source within the enclosure, and a second heat source within the enclosure. The first heat source may include an electric heater. A method of heating a swimming pool or spa using the hybrid heater includes receiving information about a desired temperature of the pool, determining an operating mode of the hybrid heater based on the received information, and controlling the hybrid heater pursuant to the determined operating mode.

  • CHLORINE-GENERATING ASSEMBLY
    Publication number: 20220064027
    Abstract: Assemblies designed to facilitate detection of water flow in low water flow situations. In some embodiments, the assembly includes a channel that narrows from an inlet end of the assembly to an outlet end of the assembly to increase the velocity of water flowing through the channel. In some embodiments, the assembly may also include a water delivery mechanism that delivers water flowing through the channel to a flow sensor and enables the detection of water flow, even in low flow situations.

  • Lighting assemblies
    Patent number: 10072832
    Abstract: Aspects of lighting assemblies principally for pools and spas are addressed. The assemblies may be configured to operate without penetrating housings thereof, thus not adversely impacting waterproof characteristics of the housings. This result is especially beneficial when the housings are installed underwater within pools or spas.
