Problem Cause Solution
Water heater is heating, but the water
temperature is not hot enough�
User temperature setting
too low�
Increase the temperature setting
on the unit�
Flow rate is too high�
Depending on your incoming
water temperature and the kW of
your heater, your water flow rate
may exceed the physical heating
capacity of your water heater�
Reduce the flow rate by installing
a Flow Regulator�
Crossed wires�
If it’s a new installation, have
your electrician double check the
wiring� Is possible that the wiring
is incorrect�
Voltage less than 380 volts
(3-Phase models) or less
than 220 volts (Sin-
gle-Phase models)�
The heating elements on your
water heater are design for 380-
415 volts (3-Phase models) and
220-240 volts (Single-Phase
models)� When used with a
lower voltage, they produce less
heating power� You may need to
upgrade to a larger input heater�
Mixing too much cold water�
You do not need to mix as much
cold water with your tankless
water heater compared to when
you use a conventional water
heater� You may also have an
anti-scald feature on your faucet
that is mixing cold water� These
types of faucets can usually be
adjusted to reduce the amount of
cold water mixed�
