In the installation, three boilers for heating and clean hot water in parts of the airport must be supplied. That installation would consist of two main motors from which the pressure units would suction, each unit from each tank. The suction line could be modified manually if required. Each pressure unit would supply a circuit with two burners; one of them would be a reserve burner. Both circuits would be designed in a way that, if one of the burners stops working, the operation of the installation could be guaranteed with manual operation valves.
