Test Your Knowledge on Sustainable Heating

• Storing heat underground is effective because the ground acts as a great insulator.
• Mälarenergi in Sweden is using underground caverns to store heat for several weeks.
• The system should be stable once the temperature of the adjacent soil increases.
• The heat from people and trains in London's metro has raised the temperature of the surrounding clay, making it difficult to cool the trains and platforms.
• Finland's Helen company has a similar system in place, supplying heat to 25,000 apartments.
• A significant number of abandoned coal mines in the UK are naturally warm and could be used to heat nearby homes.
• The water from these mines could be further heated using a heat pump system before being distributed to homes.
• Heat exchangers could be used to prevent contaminants from the mine water from entering the domestic supply.
• These solutions are considered great by experts.
• The text focuses on the use of underground heat storage as a sustainable and efficient way of heating homes.
