Erfurt (dpa/th) - Fewer and fewer gas heaters are being installed in new Thuringian apartments. In more than half of the 1734 new residential buildings (55.2 percent), renewable energies are the primary energy source, as the State Statistical Office in Erfurt announced on Friday based on figures from 2021. Accordingly, gas was only used as a primary energy source in 40.7 of the new residential buildings. Compared to the previous year, this was a decrease of 3.2 percentage points. Oil, electricity or coal heated only 1.3 percent of new buildings.
According to the statisticians, where renewable energies were used, these were primarily environmental thermal systems (78.7 percent) that extract heat from air or water. Geothermal systems, which use heat from the earth's interior, were planned for 12.7 percent of the new buildings.
More than half of the new buildings are also heated with an additional heater. Here the builders rely primarily on wood: More than every fifth residential building ready for occupancy is to be additionally equipped with a wood heating system.
