The starting point Hotels make high demands on warm water and comfortable heating. Heating and warm water make up as much as 20 % of the overall operating costs. In addition, a very high degree of operating reliability is necessary in heat generators in the hotel sector. In the case of the StrandHotel, the greater part of the energy requirement was to be covered from regener- ative sources all year round, in order to make operation largely independent of energy costs. The planning was based on the following facts: • Hotel with 12 rooms. Area to be heated: 2,800 m². • Central heat generator: two gas-brine heat pumps. • For flexible coverage of peak demands (e.g. in the mornings and evenings): two gas condensing boilers with wide range of modulation. • A supplementary solar installation to cover a large portion of the warm-water treatment with solar energy. • Planned energy consumption: 307 MW per year. • Energy standard: ENEV 2007. The new system ELCO succeeded in winning over the hotel’s operator with their high degree of system competence and reference systems installed in other hotels. The main feature of the system solution in StrandHotel See- blick is the two cascaded AQUATOP T 35 H brine heat pumps for heating warm water and for cooling, and 2 cascaded modulating R30 gas condensing boilers with a wide power range. The system is supplemented by a 40 m² SOLATRON R 2.5 flat collector for support of the warm-water and heating, and for the hygienic treatment of fresh water. The special hydraulics and control system ensure maximum energy utilisation in com- bination with the heat pumps, the gas condensing boilers and the solar plant. The harmonised, modular construction simpli- fied assembly and saved costs. This intelligent heating-system solution sustainably minimises the energy consumption of the StrandHotel. Monitoring of consumption is optimised via the Internet. With the Longlife service package, ELCO ensures optimised operation of the system with clear, calculable costs.
