Whole House Ventilation
Whole-house ventilation systems provide controlled, uniform
ventilation throughout a house. These systems use
one or more fans and duct systems to exhaust
stale air and/or supply fresh air to the house.
Heat and Energy Recovery Ventilators
(HRVs and ERVs) are whole house
ventilation systems that can provide
a continuous stream of fresh
outside air while exhausting
stale indoor air. These
machines are the best
ventilation solution
available for comfort,
health and safety when
constructing or remodeling a
tight home. HRVs and ERVs are
low flow systems that are usually run
continuously whenever the house is
closed up.
In typical installations, fresh outside air is supplied to
bedrooms and home oces while indoor air is exhausted
from bathrooms, exercise rooms and kitchens.
ERVs transfer heat and humidity.
HRVs transfer heat only.
