How
Many
Units
Do
I
Need?
When
determining
the
right
number
of
units
to
install
in
a
conventional
home,
the
following
items
need
to
be
taken
into
consideration:
The
insulation
factor,
and
window
size
&
placement
The
mean
outside
temperature
during
the
coldest
days
of
the
year
The
size
of
each
room
The
overall
size
of
the
home
The
number
of
floors
involved
The
Entrance
and
Egress
points
In
lieu
of
overall
engineering
calculations
and
thermal
loss
calculations,
a
general
rule
of
thumb
can
be
applied
to
determine
the
number
of
units
to
be
installed:
Notes:
Calculate
4
‐
6
hours
of
running
time
per
day
per
heater
installed
to
calculate
Btu’s
and
electrical
energy
cost.
Also,
remember
that
multiple
unit
installations
in
larger
rooms
can
be
coupled
to
the
same
low
‐
voltage
thermostat
or
regulated
separately.
