Thus the solar cell array is kept relatively cool and a larger proportion of the solar energy incident on the reflector unit is used. The invention uses electricity 1506 from the solar cells to move a transporting fluid through a heat exchanger 1504. Excess electricity may be available for local storage or use 1510, or feeding 1512 to the power distribution grid. Applications include warming swimming pools 1501, heating hot-water supplies using excess electricity, or warming, lighting and ventilating open spaces.

A method of disinfection of a dead-ended fluid line in a medical instrument such as a dialysis machine is described. The method comprises introducing a heated fluid into the fluid line, allowing the fluid to remain in the line for an experimentally determined optimal dwell period, removing the fluid from the fluid line, and then repeating the cycle for a time period sufficient to achieve a disinfection of the fluid line. The optimum dwell period and frequency for exchanging the heated fluid is determined so that the heated fluid is left resident in the line to exert a cidal effect but not so long that the it cools to the point of being ineffective, nor changed so frequently that that the time spent with no hot water resident in the line begins to detract (e.g., unduly prolong) the disinfection process. A representative cycle is introducing water at a temperature of about 85 degrees C, allowing it to reside in the fluid line for about 10 seconds, withdrawing the water, and then reintroducing water at 85 degrees C. The process continues for 1-2 hours. Variation from the representative cycle will be expected based on parameters such as the degree to which disinfection is to be achieved, the length and diameter of the fluid line, the temperature of the fluid, the ambient temperature, the presence of elements in the fluid line that contribute to heat loss, the material used for fluid line tubing, and whether the fluid comprises water or a disinfection solution such as a dilute citric acid solution. The optimum dwell period and frequency of the cycles can be determined experimentally from the teachings described herein.

An improved water heater for use in spas, hot tubs, pools, hydrotherapy pools, bath tubs, and similar bodies of water used indoors, outdoors, or both indoors and outdoors are used for both therapeutic and recreational purposes. The water heater uses heating element technology know as thick film on substrate comprising resistive elements bonded to the outer dry surface of a pipe to heat the pipe which in turn heats the water flowing therethrough. The heater is highly efficient due to the direct contact of the wet heating surface with the water and provides a smooth seamless inner heating surface by eliminating the need to pass electrical leads into the wet region of the heater. This virtually eliminates the risk of leaks in the water heater due to bulkhead fittings. The invention further eliminates the need for a heating element to be contained in the inner wet region of a spa heater, thereby reducing the risk of corrosion. The water heater is used in combination with an electronic controller having a microprocessor to control and regulate the operation of the water heater. The water heater can be used with electrical, electro-mechanical, and mechanical control systems for spas and can be retrofitted into existing spa applications.
