FAQ
Is
it
possible
to
improve
temperature
performance?
In
order
to
improve
the
efficiency
of
your
heat
pump
it
is
recommended
that
you:
protect
the
pool
with
a
cover
(floating
cover,
roller
cover,
etc.),
to
avoid
heat
loss
choose
periods
when
the
outside
temperature
is
warm
(on
average
>
10°
C)
in
order
to
facilitate
the
temperature
increase
(this
may
take
several
days.
The
actual
time
will
vary
according
to
weather
conditions
and
the
power
of
the
heat
pump)
the
higher
the
ambient
air
temperature,
the
more
efficient
the
heat
pump
will
be
keep
the
evaporator
clean
Check
that
filtration
time
is
sufficient
during
the
heating
phase,
water
flow
must
be
continuous
(24/24)
to
maintain
the
temperature
throughout
the
season,
allow
for
“automatic”
flow
of
at
least
12
hours/day
(the
longer
automatic
flow
is
used,
the
more
time
the
heat
pump
will
have
to
function
and
to
heat
the
water)
Setting
the
set
‐
point
to
maximum
will
not
heat
the
water
any
faster
