Hot Water Supply in Building Services, Architecture Design

The presentation on Hot Water Supply covered essential concepts related to water heating systems used in buildings. It explained various heating methods, including storage and instantaneous water heaters. The discussion included key components like boilers, pipes, and insulation for efficient heat retention. Different fuel sources, such as gas, electricity, and solar energy, were compared for sustainability and cost-effectiveness. Design considerations for residential and commercial applications were highlighted, ensuring safety and compliance with regulations. The presentation also addressed common issues like heat loss and scaling, along with preventive measures. Practical case studies and diagrams helped illustrate system layouts and efficiency improvements.

2. System How It Works Energy Source Efficiency Best For Limitations Solar Water Heating ☀️ Uses solar panels (collectors) to absorb sunlight, heating water directly or through a heat-transfer fluid. Sunlight High (depends on sunlight) Homes, hotels, industries in sunny regions Less effective on cloudy days or at night. Requires backup heating. Heat Pumps ❄️🔥 Extracts heat from air, water, or ground and transfers it to heat water. Works like a reverse refrigerator . Air, water, or ground heat Very high (3-5 times the energy input) Homes & buildings in moderate climates Less efficient in extreme cold. Higher initial cost. Hot Water Heat Recovery 🔄 Captures waste heat from showers, dishwashers, and industrial processes to preheat incoming cold water. Recycled heat from wastewater Moderate (saves 30-60% of energy) Industries, homes with high hot water usage Only works when there’s regular waste heat available. Geothermal Heating 🌍🔥 Uses underground pipes to extract heat from the Earth and transfer it to water. Earth’s constant underground heat Very high (consistent year-round) Homes & industries in cold climates Requires land for underground piping. High installation cost.
