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 substrate to heat the substrate which in turn heats the water flowing through the heating chamber. 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 can be used with electrical, electro-mechanical, and mechanical control systems for spas and can be retrofitted into existing spa applications.

A spa control system that measures the flow of water through the heater of a spa and accurately reports water temperature in the spa using only one solid-state sensor in the heater. The working condition of the sensor is first determined by energizing the spa heater for a brief period of time, with the circulation pump de-energized, then quickly de-energizing the heater and watching for a heat rise at the sensor. A small rise is sufficient to proceed with the flow test. The flow rate is now determined by energizing the pump, with the heater still de-energized, and observing the rate at which the moving water cools the inside of the heater. If there is no circulation of water through the heater, the temperature of the sensor will continue to rise from the energy applied when the heater was briefly energized. This rise will be quite significant and a clear indication of a flow problem. Conversely, with normal flow, the inside of the heater will be cooled to approximately the same temperature as the spa water in just a few seconds. If the flow is found to be adequate, the heater may be energized for a normal period of time. Since, while cooling, a measured number of degrees is dropped in a measured number of seconds, a flow rate can be reported to the user as an estimate of gallons per minute. The sensor is now carefully monitored for a sudden increase in temperature, which would indicate loss of a normal flow of water. It is known that the temperature of the water in the spa will be within one or two degrees of the observed temperature at the sensor in the heater, even when the heater is energized. The water temperature can, therefore, be accurately reported to the user just from measuring the temperature of the water in the heater. The only problem with making all measurements at the heater is that the real water temperature is unknown when the pump is not running. This problem can result in short heating cycles, or create the need to run the pump several times per day just to check on the real water temperature. The present invention uses artificial intelligence to find the proper time to turn the pump back on at a time when the spa is just beginning to need heat. Any errors in finding this time are added back to subsequent calculations to make future cycles more accurate.
