Footnotes regarding Table 8.1 Specification
1) at rated output, 80 °C flow temp., 65 °C cylinder temp., 45 °C DHW temp. and 10 °C cold water temp.
2) Explanation: The specific water flow rate to EN 625 is the cold water flow rate when raising the average temperature by 30 K, that can be delivered by the GasSolarUnit/GasCompactUnit in the course of two
consecutive drawings of 10 minutes duration respectively, starting from a primary temperature of 65 °C. This is based on the standard delay of 20 minutes between drawings. The GasSolarUnit/GasCompactUnit
achieves this value even at substantially shorter delays.
