• TURBULENCE PLATES 1, 2. Ceramic burner; 3. Ceramic chopper. Turbulence plates – a technology invented and patented by “Astra” engineers, used for capturing more heat from the hot exhaust smoke. It forces the exhaust smoke to hold, become turbulent and thus transfer more heat to the adjacent heat exchanger. -
Page 7: Intended Use
INSTALLATION AND OPERATION MANUAL 3. INTENDED USE The heating boiler is designed for the heating of residential and public buildings, manufacturing shops and other buildings where a closed heating system has been installed. Control and regulation devices are installed in the boiler, which automatically maintain the set water temperature, ensure economically efficient usage of the boiler and safe operation. -

HEATING BOILERS: Astra G-100E accumulate the excessive heat. If the boiler is operated without the accumulation tank, its lifetime can be shortened because, in such a case, a relatively low temperature of the outflowing water is maintained in the boiler (65-70°C). Therefore, the temperature of the water returning to the boiler from the heating system is as low as 55-60°C. - Page 9 INSTALLATION AND OPERATION MANUAL Fig. 5 Principle scheme of the house heating system including heat accumulation...
