Due to the success and influx of visitors, the owner decided to expand the resort in 2012. The new part of the hotel consists of 50 two-storey buildings with a total of 96 apartments, a reception building, a restaurant, technical rooms, a sports centre, a conference building and two new Olympic swimming pools and two leisure pools. The building services, which include the hot water supply, the temperature control of the swimming pools and the heating and cooling of the apartments, restaurants, reception and conference rooms, were designed by Elías Casañas’ engineering firm Incanae. The experts for geothermal energy and energy saving relied on pipe systems from aquatherm. Casañas and his team have been working with aquatherm products for 15 years and are convinced of the quality.

Three systems were installed at Club La Santa: aquatherm green pipe for drinking water, aquatherm blue pipe for the distribution of hot and cold water for heating and cooling and aquatherm blue pipe ti, a pre-insulated pipe for underground heating and cooling water distribution. In total aquatherm supplied more than eight kilometres of pipes. “The beauty of this installation was that we could use the aquatherm pipes in combination with geothermal and solar energy,” says Elías Casañas.

The challenge for the plant engineers was to work with aggressive desalinated water and – as is typical on Lanzarote – high humidity, which results in the formation of condensation on the pipes in the cooling area. These two factors lead to corrosion, especially in metal pipes. However, products of aquatherm consist of the material polypropylene, which does not interact with aggressive waters. The simple installation, in which the pipe and fitting are briefly heated and then joined together, saved a lot of time during assembly.

The plant has now been operating for six years and both the owner and the maintenance manager and engineers on the project are very happy with it. “Products from aquatherm have provided us with solutions even in difficult situations. During the installation of the pipes, aquatherm even exceeded our initial expectations,” explains Diego Fernández, maintenance manager at Club La Santa. “After six years of operation the aquatherm pipes and valves are like new. There is neither corrosion nor incrustation. For this reason, the circulation pumps consume the same energy as on the first day”, says Elías Casañas.
