The modernized traditional hotel Polys, located in Katachas, Pieria, was opened in mid-2012 and serves mainly domestic tourists and workers from various European countries due to the high industrial activity in the area. This project was HelioEnergy's first step in the tourism sector and is certainly one of the most successful.

The energy requirements of the hotel, due to its non-seasonal activity, are high and varied. Combined with the lack of organized support networks in the area, Helioenergy installed modern cooling, heating, and drainage systems. Polys has been equipped with a heat pump that provides domestic hot water, heating and cooling (during the summer season). The common areas of the accommodation are equipped with hydraulic underfloor heating and cooling, creating an extremely pleasant atmosphere in winter and summer. An extremely quiet and odourless biological rainwater system is responsible for the accommodation's drainage needs. A 20kW PV installation more than covers the energy needs of the accommodation, making its use completely environmentally friendly.
