WATER FLOW FLUCTUATES
More than one or two hot taps (018, 020 and 022 models) or more than two or three taps (024, M24 and
026 models) in use at the same time may cause a decrease in the hot water flow from the taps. This can also
be evident if the water heater has been installed as an in-series gas booster to a solar water heater and the
solar heated water is at a low temperature.
• Are there more than one or two hot taps (018, 020 and 022 models) or more than two or three taps (024,
M24 and 026 models) open, or are appliances such as a dishwasher or washing machine, in use at the
same time?
Ensure only one or two hot taps or appliances (018, 020 and 022 models) or only two or three taps or
appliances (024, M24 and 026 models) are on at the one time.
• Check the flow of the water from one tap, e.g. the shower.
The shower should be adjusted so the hot tap is fully open.
