    CO² REDUCTION: 2144.8 tonnes in 10 years

The Schlosshotel Lerbach is equipped with a WOLF CHP unit GTK 35 M offering 60 kW thermal and 35 kW electrical output. In addition, the installation included two WOLF gas condensing boilers MGK 250 in a cascade, together with a WOLF LS 2010 cylinder loading system with SEL 800. The additional investment in the CHP unit – as against a comparable heating system – will fully pay for itself in around four years. This benefits not only operators, but also the environment, as CO² emissions will already be lower from year one. Whilst the boiler and power station together generate around 421.8 tonnes of CO² per annum, the new CHP unit, together with a peak boiler, generate only 207.3 tonnes of CO² per year. Calculated over a period of 10 years, that represents a reduction of 2,144.8 tonnes of CO².
