general Information
The Vectaire WHHR100/90DC-B Plus Bypass heat recovery system
provides whole house mechanical ventilation to living areas, bed-
rooms, kitchen and bathrooms. It extracts stale, contaminated air
from kitchens, utility rooms and bathrooms, and uses the heat recov-
ered from this air to warm fresh, incoming air to create a flow of fresh
air throughout the dwelling. The extract and intake air streams are
separated to avoid contamination.
Heat is reclaimed from extracted air and used, via the heat exchange
process, to warm incoming fresh air. The system will operate contin-
uously to create a stable, comfortable, healthy environment avoiding
the use of excessive energy and saving heat already generated.
The heat recovery unit will generally be installed in the loft of a house
or the void above the ceiling in an apartment (but may be installed in
a cupboard) and will be connected by hidden ductwork to vents sited
in the ceilings of the rooms which require ventilation. Each unit is
commissioned individually allowing its performance to be tailored to
suit the performance required. There will be a facility to boost the extraction rate when desired (e.g when cook-
ing or bathing or pollutant levels rise). This may be done automatically or manually.
The system is designed to run continuously and should NOT be switched off except for maintenance or filter
replacement.
