Problem
Water heater is heating, but
the water temperature is not
hot enough.
28
GB
Cause
User temperature set-
ting too low.
Flow rate is too high.
Crossed wires.
Voltage less than 400
volts.
Mixing too much cold
water.
Solution
Increase the temperature
setting on the unit.
Depending on your incom-
ing 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.
If it's a new installation,
have your electrician double
check the wiring. Is possible
that the wiring is incorrect.
The heating elements on
your water heater are design
for 400 volts. When used
with a lower voltage, they
produce less heating power.
You may need to upgrade to
a larger input heater.
You do not need to mix
as much cold water with
your tankless water heater
compared to when you use
a conventional water heat-
er. You may also have an
anti-scald feature on your
faucet that is mixing cold wa-
ter. These types of faucets
can usually be adjusted to
reduce the amount of cold
water mixed.
