An electrolytic cell assembly for connection to a liquid flow line includes an electrode set, a cell housing supporting the electrode set, a cell retainer attached to the flow line and in fluid communication with the flow line, and a connection for detachably connecting the housing to the cell retainer in an operating position.

Electrolytic cell assembly

An exemplary embodiment of a heater assembly includes a heater housing structure defining an elongated heater chamber having a first port and a second port and defining a wetted side on the interior of the heater chamber and a non-wetted side on the exterior of the heater chamber. A resistive heater element is has an active region disposed within the heater chamber, free of any brazed or welded bulkhead members. The housing structure includes a first heater terminal opening and a second heater terminal opening, a first terminal end of the heater element passed through the first terminal opening from the wetted side to the non-wetted side, and a second terminal end of the heater element passed through the second terminal opening from the wetted side to the non-wetted side. First and second seal members are disposed on the non-wetted side respectively onto the first terminal end and the second terminal end and in contact with respective first and second seal surfaces defined on the housing structure. First and second fastener members respectively engage the first terminal end and the second terminal end and the first and second seal members. The housing structure may be fabricated of plastic, with respective current collectors in the form of unitary wire forms disposed at opposite ends of the housing structure.

Bathing installation heater assembly

A method and apparatus for circulating water in a bathing installation with a water circulation flow path and a tub for holding bathing water is described. A pump is submerged in a chamber in the circulation flow path so that the pump when operated provides a positive pump pressure to pump water through the circulation flow path from an inlet opening to an outlet opening. Thermal contact is provided between a pump housing surface and water in the chamber to allow heat transfer between the pump housing surface and water in the chamber.

Energy efficient circulation system for spas and hot tubs

A spa jet comprising a first nozzle, a second nozzle, and an aeration chamber therebetween, are all disposed in a housing. One seal forms a watertight seal between the first nozzle and the housing, and another seal forms a watertight seal between the second nozzle and the housing. A ring is affixed to the second-nozzle downstream end, and a third nozzle is pivotally mounted in the ring. A retainer is mounted to the ring and it frictionally secures the third nozzle in any one of a continuum of angular positions. The ring can be a ball-bearing ring, whereby the third nozzle can freely rotate in the ball-bearing ring under the force of a water stream exiting the third nozzle. A non-circular opening in the third nozzle assists in rotating the third nozzle even when centered in the ring. A barrel, comprising the first and second nozzles and the aeration chamber, has latching tabs formed thereon, and the housing has a retaining profile formed therein for engaging the latching tabs. A scallop has slots formed therein, and the barrel has snap tabs formed thereon for releasably engaging the slots. The housing is secured to a spa wall by a nut. A compensation spacer is disposed between the nut and the spa wall to absorb spa wall irregularities.
