The ETAhybrid systems L, XL and XXL, as a combination of heat pump and dark radiator with calorific value technology, meet the general requirements of the GEG 2024.
The ETAhybrid system L combines the split heat pump and a dark radiator with calorific value technology. The heat pump is only operated in the high COP range, which results in low power consumption. At low temperatures, using dark radiators prevents unprofitable operation of the heat pump. The system is therefore energy optimized.
