Mr Venty Condensation-Control Units
This user guide relates to the following Mr Venty products:
MOISTURE
The typical household creates around
100 pints per week - from showers,
baths, cooking etc.
CHEMICAL EMISSIONS
From everyday household furnishings,
building products etc.
FUMES
From tobacco products, exhaust
gases etc.
DUST
From furniture, carpets, bedding etc.
= Poor Air Quality = Condensation, Damp & Mould
In a dwelling of 4 people, each will contribute
approximately 4 pints of moisture per day –
through showers, boiling kettles, cooking etc
totalling over 100 pints of liquid per week. Other
airborne contaminants which exist in a typical
dwelling like dust, tobacco products, exhaust
gases – even chemical emissions from furnishing
and building products further deteriorate air
quality.
In older, less energy ecient dwellings, there is
a natural escape for this hot, damp problem air –
through ill-tting windows and doors, uncarpeted
oorboards, lofts without insulation and so forth.
Improved building features such as cavity wall
insulation, double-glazing and draft proong
prohibit ‘natural ventilation’. Stale, humid air is
trapped – increasing the condensation problem
in the dwelling.

HOW DOES MY LOFT UNIT WORK?
The Mr Venty Range of energy-ecient condensation-control units work by supplying fresh, ltered
air throughout the home to transform a stagnant and stale atmosphere into a fresh, healthy and
condensation-free environment.
The units can deliver air into a home via a single input, usually located in a central landing (ECO
2
Loft,
ECO2 Loftight and ECO2 Air models) or via twin inputs, located in a central landing and another area of
the home (ECO2 Twin, ECO2 Loftight Twin and ECO2 Air Twin).
HOW DOES MY MR VENTY UNIT HELP?
It prevents the build-up of moisture in the house, controlling steam/condensation during bathing and
cooking to prevent the formation of black mould on walls, behind cupboards etc. It will also help to stop
general dampness and musty smells caused by poor ventilation.

ENERGY SAVING BENEFITS
Your Mr Venty units also help to save energy in the following ways:
Minimum Energy Consumption
Using the latest technology, the units are powered by ultra-low watt motors to achieve low
running costs.
Solar Gain
The units* take maximum advantage of the benets from solar gain within the loft space. This
is the natural accumulation of heat from the sun on bright days. Temperatures in the loft are
on average 3°C higher than outside, which results in a relative saving of around 150 Watts per
day in an average modern family home. This equates to approximately 10% of annual heating
costs.
Heat Distribution
Warm air accumulates at ceiling level. This air can be up to 7°C higher than the internal air
at ground level. By introducing an air supply from the loft space, the Mr Venty units help to
redistribute heat around the home to further reduce heating costs.
No need to open windows
To reduce humidity and condensation during the heating season, signicant energy loss
occurs by opening windows. The Loft Units provides fresh, ltered air to the home and reduces
humidity without the need to open windows, saving energy and heat loss.
HEALTH BENEFITS:
Reduces mould spores, a trigger for respiratory problems and allergies
Reduces house dust mite populations by lowering humidity levels - a main trigger for asthma
and allergies

WHAT FEATURES DOES MY MR VENTY UNIT HAVE?
All models
The intelligent low temperature comfort heater* is designed to temper the air during periods of low
external temperatures. It is capable of holding incoming air temperatures accurately at 10°C. With the
function enabled, the heater may be on 10% of the time, depending on the fan speed setting and only
at loft temperatures at or below 10°C.
All units have an automatic increased airow setting. This function increases airow rates per setting
by 10% to deliver additional air into the property at temperatures above 19°C.
*Heater may be omitted on request by the customer.
WHAT FEATURES DOES MY MR VENTY UNIT HAVE?
ECO2 Air and ECO2 Air Twin models
Your unit is tted with an automatic summer by-pass as standard. This switches the unit’s airow from
the loft source to an atmospheric source when the temperature in the loft reaches 25°C. This is to avoid
hot air being delivered into the property and maintains the correct level of ventilation at all times.
MAINTENANCE
The Mr Venty units have been subjected to rigorous testing and are constructed from durable materials.
There should be no requirement for any maintenance within the ve year period.
