5 to 10 gallons of sizzling water with recovery times ranging from 30 to 60 minutes. Burner apparatus together with a burner, is disposed in an operative relationship with the heat exchanger for heating water flowing by way of the heat exchanger. An electronic direct spark ignition board and a Gas Regulator with an routinely controlled Dual Solenoid shut-off valve are provided for operating the burner apparatus in keeping with the requirements of the ANSI Z21.10.3 security standard. BTU levels at totally different water move charges. This characteristic is achieved using a low price metallic disc thermostat to instantly activate the Dual BTU valve without the necessity of an costly microprocessor management. This can be a mandatory safety function sometimes called a Limit Switch. A further safety feature is achieved by incorporating a Relay and a steel disc thermostat on the exhaust housing that trigger the induced draft blower to stay working after every burn until the exhaust housing reaches a low temperature, thus eliminating thermal stress on the heat exchanger and exhaust components.

FIG. Three is a perspective view of the heater shown in FIGS. FIG. Four is another perspective view of the Cyber Heater proven in FIGS. FIG. 5 is a functional diagram of the heater proven in FIGS. 10 in accordance with the present invention includes a sealed housing 14 , fabricated from any appropriate material akin to metal, which includes an air inlet 18 and a flue outlet 22 . 26 features a plenum 30 with surround tubing 34 related to a chilly-water inlet 36 and a scorching water outlet 38 . As proven in FIG. 2 , the cold-water inlet 36 and CyberHeater hot water outlet 38 prolong outdoors of the sealed housing 14 . Burner apparatus forty two includes a burner 44 which is disposed in an operative relationship with the heat exchanger 26 for Cyber Heater Unit heating water flowing by way of the tubing 34 . 74 also displays the flame of the burner 44 verifying the presence of ionization at the situation of a spark igniter 76 and promptly shuts off the gasoline move by the use of the dual solenoid valves 54 .

Forty four , regulator Cyber Heater forty eight , and [Redirect-Meta-0] solenoid valves fifty four are typical and are available from several home and international suppliers to be used in conventional fuel appliances. BZB02A0502 with Dual BTU possibility. An exhaust system fifty eight including a blower 60 with blower motor 62 , blower relay 64 , ignition relay sixty six , Cyber Heater Portable and time delay change 68 (See FIG. 5 ), is provided for inducing draft of air from the air inlet 18 by the heat exchanger 26 and out of the flue outlet 22 . This significantly enhances the efficiency of the burner forty four heat exchanger 26 , and as hereinbefore famous, offers the efficiency advantages relating to condensation supplies stressing and wind resistance.
