What Are HRVs and ERVs?
T
o understand these products and
their functions, here are a few things
to remember.
H
eat Recovery Ventilators (HRVs)
are recommended for colder areas of the
country that have longer heating seasons
a
s well as drier desert areas of the South.
Energy Recovery Ventilators (ERVs)
are designed for warmer, humid climates
w
ith longer cooling seasons.
Heat Recovery Ventilators and Energy
Recovery Ventilators are complete whole
house ventilation systems that incorporate
a supply motor and an exhaust motor in
one unit. The supply motor draws fresh air
in from the outside and the exhaust motor
pushes stale contaminated air out. The
two air steams are separated by a heat/
energy recovery core which tempers the
air making it the most comfortable solution
for a healthy indoor environment.
For information on how these units can
help you save energy and lower heating or
cooling costs, read “How Do They Work”.

How Do They Work?
Heat Recovery Ventilators (HRVs)
An HRV is designed to bring a continuous supply of fresh air into a home
while exhausting an equal amount of contaminated air. HRVs use what is called
a “sensible” heat recovery core. This special aluminum core transfers heat
from the exhaust air stream to the incoming air stream. Fresh incoming air is
tempered by the heat that is transferred from the outgoing air so you save on
energy costs. Fantech HRVs are equipped with automatic defrost mechanisms
so even if you live in the coldest climates you can use your HRV all year long.
Energy Recovery Ventilators (ERVs)
Fantech’s ERV works much like the HRV but it is designed with a different
type core. The enthalpic core at the center of the unit transfers heat and moisture
from the incoming air to the outgoing air. The air brought into the living area is
cooled and the humidity is reduced for maximum comfort. The load on your
air conditioner is less and you save on cooling costs.

Port Configurations
Five Port Models feature motorized damper for
recirculation mode and defrost. Positive shut off of
supply port when unit is in standby.
Four Port Models provide constant ventilation even
in defrost mode without the need for additional parts.
An exhaust only (fan shut down) defrost strategy is
an effective method at an affordable price.
