Tech/Engineering - Energy / Power Generation / Solar hot water storage unit

German term or phrase: Dauerleistung VL 80 °C, ZT: 45°C (L/h)

This is a list of specifications for a solar hot water storage unit, with things like height, diameter, rated output. I know that Dauerleistung is continuous output, but can anyone work out what VL and ZT are please?

21 mins confidence:

Vorlauf / Zirkulationstemperatur

Explanation:
VL stands for "Vorlauf", and ZT probably stands for "Zirkulationstemperatur" (another option is "Zonentemperatur", but not as likely).
Standard terminology in hot water heating circuits.
Vorlauf = supply flow / outflow
Rücklauf = return flow
However, the (L/h) is slightly puzzling, unless it is followed by a value that specifies the hourly (circulation) flow rate.

Notes to answerer

Asker: Sorry to close this without grading - I'd like to have split the points between you, but I can't. I went for your "supply flow" and Bernd's "tap temperature". Thank you very much for your helpful answer.

Nochmal auf deutsch:
Ich kann bei einer Vorlauftemperatur von 80 °C pro Stunde X [die Zahl müsste in der nächsten Spalte stehen] Liter Warmwasser mit einer Temperatur von 45 °C zapfen.
