        <p>
            Consumption data is used to calculate the fuel consumption and operating costs of boilers at different temperatures.
            This information helps OptiWarm optimize heating schedules to minimize costs.
        </p>
        
        <h6 class="mt-3">How Consumption Data Works:</h6>
        <ul>
            <li>Record the temperature setting for a boiler</li>
            <li>Measure the fuel consumption over a specific time period</li>
            <li>OptiWarm uses this data to calculate the cost per hour at each temperature</li>
            <li>The heating schedule optimizer uses these costs to minimize expenses</li>
        </ul>
        
        <div class="alert alert-info mt-3">
            <i class="fas fa-info-circle mr-2"></i>
            For the most accurate results, provide consumption data for multiple temperature settings across the operating range of each boiler.
