The gas heat pump Logatherm WSW 192i from Buderus is winning in the categories of high quality, design, functionality and ecology. Different from the standard gas condensing boiler technology, the Logatherm saves up to 30% of energy cost and CO2 emission. Mechanical components guarantee its quality and reduce maintenance costs; the cooling circuit itself is maintenance-free. The Logatherm can be used for one- and two-family houses and also be combined with other systems, e.g. geothermal energy or photovoltaics. The design of the Logatherm with the titanium glass surface looks elegant and fits into the design of modern household devices.
