General Information
The Vectaire WHHR100/60DC heat recovery system provides
whole house mechanical ventilation to living areas, bedrooms, kitchen
and bathrooms. They extract stale, contaminated air from kitchens,
utility rooms and bathrooms, and use the heat recovered 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 exchang-
er, to warm incoming fresh air. The system will operate continuously
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 cooking or bathing or pollutant levels rise). This may be done automati-
cally or manually.
The system is designed to run continuously and should NOT be switched off except for maintenance or filter
replacement.
