To reduce the hotel's energy costs, two liquid gas-fired combined heat and power plants supply the hotel with electricity and the spa area with heat.
Hotelier Marc Traubel, owner of the Hotel Hubertus Mountain Refugio Allgäu in Balderschwang, Oberallgäu, opted for an efficient energy concept when building his new spa area in 2019. Instead of a large and rather unprofitable pellet heating system, which supplied the spa area and the hotel, two liquid gas-powered combined heat and power units, each with 50 kW of electrical heating, now work much more efficiently and economically.
The liquid gas is stored in an underground 30 t tank. Secured with a concrete slab and buoyancy protection, it was installed avalanche-proof in the slope behind the hotel. And equipped with a drive-over dome shaft.
Two pellet boilers only cover the peak load when the heat demand is particularly high. As liquid gas is not piped, the concept increases the security of supply for the business.
As an accommodation provider in a vacation region that thrives on unspoilt nature, it is very important to keep the hotel's emissions as low as possible. This is why the decision was made to use liquid gas. Compared to the previous pellet heating system, the energy balance has been significantly improved.
