Quart de Poblet, Spain
Hotel | 137 sqm installation
| |
Description The installation is formed by 72 SOLAHART collectors, mod. L, situated in a suitable area. The 72 collectors are divided into 12 batteries of 6 collectors. The system uses a variable temperature control system which operates the primary and secundary circuits. The collector heat is transferred to the storage tank by an external heat exchanger. The variable temperature setting to start/stop the circulation pumps is 6 ºC. System use: ACS with a solar fraction of 80 %.

The owner of the hotel was interested in solar system, he knew all the costs, the investment and the savings were calculated.
The director of the Hotel contacted the installer and the technical department of SACLIMA designed the installation and provided the solar system.
The installation is working right.
