slimline, efficient, low energy solution to
controlling condensation and pollution.
It provides low level continuous ventil-
ation in a kitchen and up to six wet
rooms, extracting moist, polluted air
and replacing it with fresh, filtered air -
recovering up to 79% of the heat from
the outgoing flow.
The user can to boost to maximum
performance when required. The
slimline WHHR100/90DC is easily
installed in the loft or roof void, or a
cupboard The noise level and running
costs are extremely low, and it is com-
pliant with Parts L and F of the Building

The Vectaire WHHR100/90DC heat recovery system provides
who e house mechanica venti ation to iving areas, bedrooms, kitchen
and bathrooms. They extract sta e, contaminated air from kitchens,
uti ity rooms and bathrooms, and use the heat recovered from this air
to warm fresh, incoming air to create a f ow of fresh air throughout
the dwe ing. The extract and intake air streams are separated to
avoid contamination.
Heat is rec aimed from extracted air and used, via the heat exchang-
er, to warm incoming fresh air. The system wi operate continuous y
to create a stab e, comfortab e, hea thy environment avoiding the use
of excessive energy and saving heat a ready generated.
The heat recovery unit wi genera y be insta ed in the oft of a house
or the void above the cei ing in an apartment (but may be insta ed in
a cupboard) and wi be connected by hidden ductwork to vents sited
in the cei ings of the rooms which require venti ation. Each unit is
commissioned individua y a owing its performance to be tai ored to
suit the performance required. There wi be a faci ity to boost the
extraction rate when desired (e.g when cooking or bathing or po utant eve s rise). This may be done automati-
ca y or manua y.
