Retrofit of a Solar System in Sport Center in Mallorca

The building was built in the late 90s, had a solar installation of 200 m2 with 4 tanks of DHW and the support of diesel boilers and district heating. After 16 years 25% of the solar collectors are damaged, and some of the storage tanks have rust and lime with leaking. A new design and retrofit is needed to improve the existing installation. New advanced systems are being designed in different phases. The first phase consists of installing new collectors and combisystems tanks. If we add the pool to the system, it is further possible to improve the water management of the building. During this first phase 25% of the solar field will be added with higher efficiency collectors. The estimated energy savings are 14% and the cost savings will be near to 30%.
