Climate protection and economic savings do not need to exclude each other. This is proven by Seniorenresidenz Rahlstedt in Hamburg with its modern way of heating. Since february 2009 it relies on the innovative contracting model and got a compact CHP unit GG 50 by SOKRATHERM installed.

This reduces the energy costs by impressive 16.000 Euro per year. At the same time it gains from the comfortable service heating package and does not need to care about maintenance or repairs. And since it applies especially CO2-saving heating technology, director Markus Berns can carry the title UmWeltmeister in the category accomodation and gastronomy. „It feels good to do something for the environment and to enjoy such tangible advantages as cost reduction and full heating service at the same time! I would recommend contracting to everybody.“ resumes Markus Berns.full article (in German, published in IKZ Energy 5/2010)
