Modern spa benefits from green technology

Welcome to the heart of the UNESCO natural heritage area «Aletsch-Jungfrau»

The Aletschspa and the Alex Hotel

The Aletschspa is the newest part of the Alex hotel and is fully dedicated to spa and wellbeing facilities. It features an 80 m2 pool and offers many ways to relax, from the ergonomically shaped bubble loungers to the air-filled “aqua rondo” water station. The spacious pool has enough room for aqua-fitness. Children can enjoy splashing around in the small fountain in the separate children’s pool.

“Thanks to Thermia’s modern and efficient geothermal energy system, the new Aletschspa can entertain its guests in the knowledge that they are caring for the environment and saving money.” Milos Bill, Managing Director, eta Group

Low-carbon system in wellness center

The Aletschspa is heated by two inverter-driven Thermia Mega ground-source heat pumps with a heating capacity of 14-59 kW. Ground water with a temperature of around 10°C is the energy source for the heat pump. The heating system covers floor heating as well as pool and floatation pool heating. Cooling (air-conditioning) is provided by passive cooling, which means that energy to cool the facilities comes from the ground water.
Domestic hot water is provided by a compact heat transfer station mounted on one of the tanks. The primary side uses returned (re-used) hot water to heat the clean domestic water. The advantage of this is that the inverter technology, heat transfer station and hot gas technology combine to provide more hot water at a higher temperature. This removes the need for a hot water tank and eliminates potential problems with legionella bacteria as all hot water is produced ‘just in time’.
