Effective damp-proofing solutions
Damp is a common issue in traditional pueblo townhouses in Spain, especially those with older foundations. In such properties, injected damp-proof courses (DPC) often prove insufficient, as damp from neighbouring properties (particularly those uphill) can seep through. For a long-term solution, consider “tanking” the lower and ground floors. This involves installing a comprehensive damp-proof barrier beneath the floors and up the walls, extending to ceiling height on the lower floor and ideally on the ground floor as well. By reinforcing damp-proofing along the uphill and adjacent walls, you can better prevent damp from creeping through shared walls.
Adding underfloor heating for comfort
Renovating to include underfloor heating is an effective way to enhance comfort in traditional homes while tackling damp issues. A recommended option is water-based underfloor heating connected to an air-to-water heat pump, which distributes heat more evenly. Avoid electric underfloor heating, as some individuals have concerns about electromagnetic radiation. Ensure proper ventilation to prevent stuffiness and maintain good air quality in these damp-prone areas.
Why choosing an air-to-water heat pump helps damp?
An air-to-water heat pump is an energy-efficient heating system that transfers heat from outdoor air to a water storage tank. This heat can be distributed through radiators or underfloor pipes, providing efficient central heating and hot water for showers, baths, and sinks. Compared to traditional electric or gas heating systems, air-source heat pumps can produce up to 75% more energy, significantly reducing emissions. Additionally, they improve a property’s Energy and CO2 rating, making this system an eco-friendly and cost-effective heating solution for homes prone to damp.
By investing in proper damp-proofing and efficient heating solutions, traditional townhouses can achieve better moisture control, enhanced comfort, and improved energy efficiency.
