| 20090120923 | WATER HEATER OF ENDORSEMENT WITH IONIZED IGNITION AND ELECTRONIC CONTROL OF TEMPERATURE, FOR SOLAR HEATERS OF THE TYPE THERMOSIPHON - A backup water heater for a solar water heater operates by means of an electronic card that initiates the operation of the heater in response to temperature and flow signals. A burner is lit gradually by an electrical spark emitted by a spark plug connected to the electronic card, which controls gas feed to the burner. As soon as the burner is lit, the electric current generated by the first spark plug is transformed by the ionization effect, changing the polarization of the current, which is detected by another spark plug that emits the change signal to the electronic card for further control of the water heater. | 05-14-2009 |
| 20090120427 | WATER HEATER OF ENDORSEMENT WITH IONIZED IGNITION AND CONTROL OF ELECTRONIC TEMPERATURE FOR HEATERS OF CIRCULATION FORCED WITH SOLAR APPLICATION OF ENERGY - The forced recirculation solar water heating system with a backup water heater works through an electronic card that initiates the operation and activation of the water recirculators when there is a difference of 2° C. between the panel and the storage tank [detected] by means of a bimetallic cable connected at one of the top ends of the panel and another bimetallic cable at the upper part of the storage tank, which has a series of safety check valves that prevent temperature loss due to hot water backflow to the hydraulic network or due to natural reverse recirculation, thus avoiding excess pressure in the system. | 05-14-2009 |
| 20090120381 | WATER HEATER WITH IONIZED IGNITION AND ELECTRONIC CONTROL OF TEMPERATURE - A water heater is controlled by an electronic system that initiates the operation of the heater when a flow detector sends a demand signal for hot water flow to the electronic card, which ignites a burner as function of a temperature programmed by the user. The burner is lit gradually by an electrical spark emitted by a spark plug connected to the electronic card, which in turn controls gas feed to the burner. As soon as the burner is lit, the electric current generated by the first spark plug is transformed by the ionization effect, changing the polarization of the current, which is detected by another spark plug that emits the change signal to the electronic card for further control of the heater. The heater operates without a permanently lit pilot light. | 05-14-2009 |
