“the facts”
What causes indoor
air pollutants?
Indoor air quality
and asthma.
In short, we do!
It is estimated that some 80%
of asthmatics are allergic to
dust mites (or more specifically
to the faeces of these creatures).
Dust mites are too small for
us to see but they can be
present in huge quantities in
soft furnishings and more
worryingly, in our mattresses
and pillows.
We wash, we cook, we clean.
The faeces can also float in
the air when you shake your
bedding or when you walk
over the carpet where they
have settled.
We use aerosols.
We decorate and furnish
our homes.
How can external
pollutants enter
the home?
Obviously through open doors, windows,
air bricks and trickle ventilators (usually
housed above your double glazing).
But, there are other less obvious points
of entry. Every home has thousands
of tiny gaps through which unfiltered
and unheated external air can enter.
Even modern homes built to current
Building Regulations will have some
degree of uncontrolled air leakage.
Some of us smoke.
All of us breathe.
All of the above day to day
activities can contribute
pollutants to some extent.
Combined, they can have a
significant impact on the
quality of air in our homes
and consequently our health.
Good ventilation will deal
with these pollutants.
3
It is the inhalation of this
allergen that can trigger an
asthma attack.
Dust mites breed best in a
humid environment.
Just the sort of environment
you will have if your home is
poorly ventilated.
Ventilating a home can create
a hostile environment for the dust
mite; mite populations can fall
and faeces production reduced.
Clinical research has proven
that whole home ventilation
can play a significant part in
controlling dust mite allergens.
Nuaire's own experience
through hundreds of reports
from satisfied customers, who
claim significant relief from
their condition, backs up
this research.
NB. Nuaire do not claim that the use of their
products will cure asthma nor eliminate
asthma attacks.

“excess water vapour...
the major pollutant”

Just where does
condensation
come from?
”a growing problem”
These days there is no stigma attached to
having condensation dampness in our homes.
It is a common consequence of modern living
and more energy efficient homes.
How condensation
can affect the fabric
of our homes and
our health.
From us! Through bathing
and showering, cooking,
washing and drying our
clothes and by us just being
there, because every human
emanates moisture.
It is estimated that all this
amounts to 4 pints per day
per person!
Most homes will experience
condensation on their windows
and in many cases windows
will stream with water.
The limitations of
extract fans...
• Usually activated at time of moisture
production which is often too late.
• Rely on additional background
ventilation such as trickle ventilators,
throughout the home.
• Can be noisy.
• Need considerable maintenance/
cleaning for efficient operation.
• Can use significant electrical
power.
• Draw in unheated, unfiltered air
into the home.
• Can compete for air with opened
flued combustion appliances which
can result in poisonous carbon
monoxide gases entering the home.
...and what about
dehumidifiers?
• Do not ventilate a home.
• Can consume large amounts of
electrical power.
• Can be noisy.
• Require regular emptying of
condensate.
But condensation can also
lead to mould growing on
our walls and in some cases
on our clothes when stored
in wardrobes.
This is not only unpleasant, it is
damaging and costly causing
premature redecoration or
replacement.
This dampness can also be
evident through musty smells
in our homes.
You can't see this moisture
once it is absorbed into the
indoor air, until such time as
it comes into contact with
a cold surface for it to
condense on.
This is why significant
condensation will occur
overnight as the fabric of
the building cools
We have all seen this effect
on bedroom windows first
thing in the morning.
This is the result of moisture
laden air condensing on
the cool surface of the
bedroom window.
Condensed water on the
surfaces of our homes provides
ideal conditions for mould
spores already in the air to
germinate and grow.
Many people associate this
mould growth with health
problems.

Home Ventilation
“the modern way to
ventilate your home”

“low energy positive input ventilation”
The UK’s most popular method of
whole home ventilation
Energy benefits.
Your roof is an energy source.
South east to south west facing tiles or
slates absorb energy from the sun.
Even the loft space itself is a
substantial source of energy. During the
heating season it will almost always
be warmer than outside because of
solar gain and conduction and
convection losses from the home.
Positive input ventilation units use
the tiles/slates and/or the loft space
itself to warm the incoming air
before delivering it into the home.
Solar air collectors can also be used
for even greater pre-heating of the
ventilation air.
This has the effect of helping to heat
the home which can result in lower
fuel bills and, for those interested
in the environment, reduced carbon
emissions.
The input air enters your home at
ceiling level, usually on your landing.
This method re-circulates the warm
air that rises and collects there as
well as reducing the heat loss to
your loft.
The slight pressurisation effect created
helps reduce infiltration of unheated
air through the leakage points
found in all homes, having a
consequential energy benefit.
In simple terms, a good quality low
energy positive input ventilation unit
will provide a significantly greater
amount of energy in the form of heat
into the home than the energy it
consumes in the form of electricity.
In short, providing a considerable
net energy gain.
How does low
energy positive
input ventilation
work?
Unlike extract systems
which draw in unheated,
unfiltered air, even a
basic
positive
input
ventilation unit gently
supplies tempered, filtered
air into a home using
otherwise unused heat
within a roof.
The benefits of this are
enormous;
Firstly, it means that a
significant proportion of
external pollutants are
prevented from entering
the home.
Secondly, the use of the
otherwise unused heat in
the roof results in the
ventilation unit providing
a significant net energy
gain to the home.
7
Thirdly, there is no better
way to ventilate a home
than from the inside out via
a single, centrally located,
supply air diffuser.
A good quality unit, fitted
in your loft, will operate at
an almost imperceptible
noise level. You will hardly
know its there.
A properly designed and
installed unit will ensure
that old, contaminated,
vapour laden air in your
home is continuously diluted,
displaced and replaced
with good quality air.
The result is improved
indoor air quality and an
environment in which
condensation dampness
cannot exist.
The old air exits through the
thousands of air leakage
points found in all homes.
Indeed, positive input
ventilation will even help
to suppress unwanted
infiltration (draughts).
The installation of a low
energy positive input
ventilation unit will ensure
the air in your home is
completely replaced with
better quality air around
20 times a day.
This is the recommended
rate to maintain good
air quality.

Drimaster Ecosmart
is an all year round, low energy positive input ventilation unit that
will take advantage of the solar energy collected by your roof
tiles/slates.
Your roof acts as a solar collector
The sun warms the tiles/slates, which in turn creates
a warm “boundary layer” (1) and heats the area
between top of felt and underside of tiles/slates (2).
Drimaster Ecosmart draws air from this area via a
plenum (a sealed chamber) fitted to the underside of
the rafters and a system of ductwork.The air is then
replaced with external air via the tiles/slates
1.
Over 10 million unused solar collectors in the UK!
Every roof is a potential solar collector. Drimaster Ecosmart
allows you to realise the potential of yours, whether it be a
‘warm roof’ or ‘cold roof’.
How can Drimaster Ecosmart realise the energy
saving potential in you roof?
The energy benefit of using a loft to help preheat ventilation
air has been known for many years. There is however more
energy available than just in the loft.
Extensive research has established that the air on top of
slates/tiles (boundary layer) and trapped between your
slates/tiles and the roofing felt can be significantly warmer
than your loft during the heating season. Drimaster Ecosmart
uses this additional heat, when it's available.
Drimaster Ecosmart automatically determines the best location
from which to draw warm air to suit your selected needs
by continually sensing the air temperature in the various
roof locations.
All year round ventilation
Drimaster Ecosmart operates 24 hrs a day, 365 days a year.
Unlike conventional positive input ventilation units which only
draw in air from the loft, Drimaster Ecosmart is also capable
of drawing air directly from outside. This is particularly advantageous during the non-heating season.
Your unit control will automatically select air from either outside
your home, the loft, or under the slates/tiles according to
your selection.

”ECOSUN
is an all year round, low energy positive input ventilation unit,
capable of capitalising large amounts of solar energy via
roof mounted solar air heaters“
An intelligent approach to whole home ventilation, solar air heating
and air cooling. Once you have determined your requirements at the
user control, the Ecosun intelligent control system will monitor a
plurality of temperature sensors around the system and your home.
It will then automatically control the air flow through the system to optimise
energy efficiency while always providing adequate ventilation to
your home.
High efficiency solar air heaters
Each Drimaster Ecosun comes complete with two high
efficiency, light weight and waterless solar air heaters.
These solar air heaters incorporate a unique absorber
material and have been tested to EN12975-1,2: 2002.
Method of Operation
The unit is similar in operation to the Drimaster Ecosmart as
described on pages 12-15, the only differences being that
the solar air heaters are used in lieu of the roof tiles/slates
to provide even greater energy heat gains from the sun.
Excellent aesthetics
The neutral colours used in the solar collectors help them to
blend into the vast majority of roofs. In situations where
something a bit more special is required e.g. for blending
into a pre-fabricated metal roof and there are sufficient
quantities to justify the extra expense, we are able to provide
bespoke units.

1. Roof Mounted Solar Collectors
Attractive, roof mounted solar collectors, incorporating a unique absorber material, are used to absorb
heat from the sun and transfer it to air that is passed through them. During the heating season they can
be used to help heat the home by passing the ventilation air through them before delivery to the dwelling.
When heating demand of the home has been satisfied or during the non-heating season, the collectors
can heat the hot water. The heated air is then directed via an air to water heat transfer coil integral to the
low energy air handling system. The resulting warmed water is then pumped to a storage cylinder thermal
store in a similar way to a conventional solar hot water heating system.
It is also worth noting that the collectors can even be used to help cool the ventilation air. At night the
unique absorber material can cool down as it loses heat to clear night skies. If desirable, the external air
can then be cooled by passing it through the collectors. This can be particularly beneficial during the
summer months.
2. Low Energy Air Handling System
The air handling system is of robust lightweight construction and incorporates low energy consumption
components and low maintenance, high performance air filters.
It directs the air as required to optimise energy gain while always providing whole home ventilation via the
well established "positive input ventilation" principle. Indeed at the heart of the system is a Nuaire DRIMASTER,
the UK's most popular low energy positive input ventilation unit.
3. Solar Hot Water Heating Facility
sunwarm can be supplied with a full range of hot water cylinders. It can also be easily linked to any hot
water cylinders provided by others.
4. Ceiling Mounted Supply Air Diffuser
As sunwarm provides whole home ventilation using the "positive input ventilation" principle, a single ceiling
mounted supply air diffuser is often all that is needed for adequate air distribution throughout a home.
5. User Controls
Each sunwarm system is provided with an easy to use control system that will also provide you with system
status information including when the systems filters need changing (every 5 years).
