presumed that any embodiment of the present invention would include a power source and all wires connections interfaces and power systems necessary to allow the system to interface with the plc the plc may be made accessible to the user at a control box such as control box 62 see fig2 as show in fig2 the apparatus of the present invention may be encased in an exterior casing not numbered this casing serves to contain the system and may provide some insulation such casing may have a frame 60 as shown in fig1 the boiler 10 may be equipped with several features that serve to ensure first that the boiler 10 will maintain an adequate supply of heated pressurized water and secondly that the boiler 10 does not become over pressurized such over pressurization could result in rupturing of the system or even explosion of the boiler 10 in a preferred embodiment of the present invention there is a level switch 13 that measures the water level in the boiler 10 and sends signals to the plc when there is sufficient or excess water in the boiler 10 and when water needs to be added there is also a thermocouple temperature sensor 12 additionally there may be a pressure switch 30 that interrupts the power going to the heaters 11 and pump 20 if the boiler pressure exceeds a preset pressure threshold may be included.
