In order to develop a common approach for the the solar thermal use for outdoor swimming pools in Europe a baseline study was performed in the participating countries to collect the folowing information.
- State of the art of the energy supply of outdoor pools (techniques, fuels, concepts, etc.) inclusive the market size analysis
- State of the art of solar thermal applications for outdoor pools (available technologies and systems, future applications, etc.) inclusive the market size analysis
- Potential of solar thermal applications in outdoor swimming pools (case studies, performance data, energy savings, market potential, etc.)
- Identification of barriers hindering the extended application of this technology (technical, political, financial, etc.)
- Identification of BATs (Best Available Technologies)
- Collection of basic data of outdoor swimming pools relevant for the project (size, number of pools, piping, pumps, insulation, etc.)
- Collection of basic data of regional solar firms with experience in planning and installing (expertise, realised projects, components used, supplier, etc.)
- Identification of best practices (features, problems, costs, etc.)
- Identification of existing grant schemes and their effects in the participating countries (e.g. existing and new grant schemes, solar market development without and with grant schemes or after their implementation, policy development or regulatory issues)
These studies formed the basis for the development of the national fact sheets, requirement sheets for solar thermal use and funding sheets on existing grant schemes:
The main objective of the SOLPOOL project is to develop and implement campaigns for the increased use of solar thermal systems for the heating of outdoor swimming pools. In order to develop the campaigns, first a common approach for the Implementation of Solar Heating Systems for Outdoor Swimming Pools in Europe has to be developed. Based on the performed baseline study the project team developed a common European approach for the promotion of solar energy us for the heating of outdoor swimming pools.
Please see the developed common approach below:
In SOLPOOL the use of solar thermal energy for the heating of outdoor swimming pools should be strengthen. Solar energy is one the best and most cost-effective methods to heat swimming pools.
The extended application is limited by several boundary conditions. These limitations must be overcome to establish solar energy as a common power supply for pool heating systems. The solar energy use will replace the conventional combustion system with fossil fuels. This will lead to a significant reduction in CO2 emission. But the heating of pools is still a niche application. Although in France, one of the first markets for swimming pools, the number of pools is given with more than a million. Therefore, not every single one is heated.
But case studies have shown, that there is an enormous potential of reducing emissions and fuel costs, for example a pool in France (Villeurbanne) saved with a collector area of 1100m² 91 t CO2 and 12.000 € costs for gas per year. So the use of solar energy will not only have an ecologic impact, but also the running cost will be reduced. Despite of these obviously advantages, solar thermal pool heating systems are not widely-spread.
