A modulating heater system for a pool or spa includes a pool or spa heater capable of variably modulating energy output thereof and a controller communicatively coupled thereto. The controller determines a predicted load based on a previous load, ambient and water temperatures, and estimated pool/spa size, and determines an overshoot setpoint for an operational mode. The controller establishes a target temperature setpoint for the mode and receives a current water temperature. The controller determines whether the overshoot setpoint plus target temperature setpoint is greater than the current water temperature, and determines an error based thereon. The controller determines if the error is less than or greater than a target for the mode, and, based on this determination, determines a heater modulation rate for the mode taking into account the mode, maximum heater output, and available fuel supply. The controller controls the heater to operate at the determined modulation rate.

Modulating pool or spa heater systems and associated methods

An inlet mixer system for a gas heater includes a housing in fluid communication with an inlet of a combustion blower, and first and second mixer inserts, each removably positionable within the housing. Each mixer insert includes a body defining a mixing chamber, an air intake, and a plurality of orifices disposed radially about the body and extending through the body, which provide respective volumetric flow rates of a fuel gas. When the first mixer insert is positioned within the housing, the inlet mixer system is configured for use with a first fuel gas, and when the second mixer insert is positioned within the housing, the inlet mixer system is configured for use with a second fuel gas.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. 'Internet-of-Things' (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes ('pool logic') which can be embodied as software code installed in any of the various embodiments of the present disclosure.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment

Swimming pool or spa gas heaters, cabinets, water header manifolds, and heat exchangers include: gas heaters having an air gap between a cabinet and combustion chamber to reduce heat transfer to sides of the cabinet; gas heaters having a user interface that is repositionable on a top panel; gas heater cabinets including a removable top panel that can be hung on a side panel; gas heaters having a built-in dual junction box; gas heaters having a top-accessible igniter and burner that are interlocked to maintain positioning thereof; adaptable water manifolds including connectable inlet and outlet fittings that adjust effective inlet and outlet positions; heat exchangers having a plurality of tube-and-fin subassemblies arranged in a semi-circular configuration; and water manifolds including internal cartridges that divide the water manifold into a plurality of chambers for improved circulation through a heat exchanger are disclosed.

Compact universal gas pool heater and associated methods

An electric plug locking device (10), which remains affixed to an electric plug (13) for preventing unsupervised use of electrical equipment, has an upper housing member (11) movably mounted to a lower housing member (12). The upper housing member which has an opening (23) for receiving a plug terminal (15) moves from a position that shields the terminal to prevent it from being inserted into an electrical socket to a position that unshields the plug terminal to permit it to be inserted into the socket.
