What Are HRVs ?
To understand these products and
their functions, here are a few things
to remember.
Heat Recovery Ventilators (HRVs)
are recommended for colder areas of the coun-
try that have longer heating seasons as well as
drier desert areas of the South.
Heat Recovery Ventilators are complete whole
house ventilation systems that incorporate a
supply fan and an exhaust fan in one unit. The
supply fan draws fresh air in from the outside
and the exhaust fan pushes stale contaminat-
ed air out. The two air streams are separated
by a heat 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?”.

Heat Recovery Ventilators (HRVs)
An HRV is designed to be a cost-effective and reliable
way to bring a continuous supply of fresh air into a
home while exhausting an equal amount of contaminat-
ed air. If it is properly maintained, an HVR can meet a
home's total ventilation requirements by itself. 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.

Port Configurations
Five Port Models feature motorized damper for recir-
culation 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.
