NOTE: The heat-up time is based on a primary flow rate of 9
l/min at 80 °C. Temperature rise from 5 °C to 65 °C
Static operating pressure of the cold water supply
The displayed flow rates apply to installations in which the
cold water supply is of appropriate dynamic pressure.
Please contact Glow-worm if the static water pressure is
below bar.
