Solar combisystems - thinking big for a sustainable energy future. Adopted on a wide scale, this technology can significantly reduce carbon emissions. European Commission stated goals for solar thermal by 2010 correspond to an overall installed collector area of 100 million m2 - that's 120,000 solar combisystems each year. Here, Werner Weiss takes a look at what is already on the market, and at international measures to introduce better systems and standards. DHW storage is 2 x 0.8 m3 while the heating storage tank is 5 m3 with built-in stratifier.
Auxiliary heating is from a woodchip boiler.
AEE The increase in the use of solar collectors in recent years for domestic hot water heating has shown solar heating systems to be a mature and reliable technology. Every day, thousands of systems worldwide demonstrate the possibilities of this undisputedly ecologically harmless energy source. Motivated by the confirmed success of these systems for hot water, increasing numbers of house builders are considering solar energy for space heating, as well.

In Austria, Denmark, Germany and Switzerland, for example, they have a significant market share, as Figure 1 shows.
