5 to 10 gallons of scorching water with recovery instances ranging from 30 to 60 minutes. Burner apparatus including a burner, is disposed in an operative relationship with the heat exchanger for heating water flowing through the heat exchanger. An digital direct spark ignition board and a Gas Regulator with an automatically managed Dual Solenoid shut-off valve are provided for working the burner apparatus in line with the necessities of the ANSI Z21.10.Three security normal. BTU levels at different water stream rates. This feature is achieved using a low cost metal disc thermostat to straight activate the Dual BTU valve with out the necessity of an expensive microprocessor management. This can be a obligatory safety feature often referred to as a Limit Switch. An additional security feature is achieved by incorporating a Relay and a metal disc thermostat on the exhaust housing that cause the induced draft blower to remain working after every burn till the exhaust housing reaches a low temperature, thus eliminating thermal stress on the heat exchanger and Cyber Heater Portable Unit exhaust components.



FIG. Three is a perspective view of the heater proven in FIGS. FIG. Four is another perspective view of the Cyber Heater Portable Unit proven in FIGS. FIG. 5 is a functional diagram of the heater shown in FIGS. 10 in accordance with the current invention features a sealed housing 14 , fabricated from any suitable materials resembling metal, which includes an air inlet 18 and a flue outlet 22 . 26 includes a plenum 30 with encompass tubing 34 related to a cold-water inlet 36 and Cyber Heater a scorching water outlet 38 . As shown in FIG. 2 , the cold-water inlet 36 and hot water outlet 38 lengthen outside of the sealed housing 14 . Burner apparatus forty two includes a burner forty four which is disposed in an operative relationship with the heat exchanger 26 for heating water flowing by the tubing 34 . Seventy four additionally screens the flame of the burner 44 verifying the presence of ionization at the situation of a spark igniter 76 and promptly shuts off the gas flow by the use of the twin solenoid valves fifty four .



44 , regulator forty eight , and solenoid valves 54 are conventional and are available from several home and foreign suppliers for use in conventional gasoline appliances. BZB02A0502 with Dual BTU possibility. An exhaust system fifty eight together with a blower 60 with blower motor sixty two , blower relay 64 , ignition relay 66 , and time delay change sixty eight (See FIG. 5 ), is supplied for inducing draft of air from the air inlet 18 by means of the heat exchanger 26 and CyberHeater.com out of the flue outlet 22 . This enormously enhances the efficiency of the burner 44 heat exchanger 26 , and as hereinbefore famous, gives the efficiency advantages regarding condensation supplies stressing and wind resistance. 74 with a spark igniter 76 which may be of any accepted standard design certified by an appropriate agency (i.e. CSA, UL or different), is provided for working the burner apparatus 42 and the exhaust system 58 .



80 is supplied in the recent water line to offer pressure relief in case of overheating in the recent water line 38 in a traditional method.
