Condensation and Mould
In Britain, condensation in houses is a problem particularly where warm moist air is generated in areas like kitchens and bathrooms or by drying clothes over radiators. The moisture in the air gets left on surfaces in colder parts of the house resulting in water running down the windows leading to black mould on walls, ceilings and in cupboards.
The ‘average’ family produces approximately 27 pints of moisture per day.
How can we reduce humidity levels:
- Adequate Heating – Air is like a sponge, the warmer it is the more moisture it will hold
- Adequate Insulation – Prevents cold surfaces for moisture to condense
- Adequate Ventilation – Removes the excess moisture held in the warm air and provides fresh air resulting in better indoor air quality
Provide adequate ventilation
Traditional intermittent extract fans provide peaks of airflow, this means we
are warming indoor air and then extracting it to outside, which is not energy
efficient.
Instead, continuous running extract fans in bathrooms, kitchens and utility
rooms work with the natural air flow in the house meaning you have a constant
supply of fresh air which prevents germs multiplying and spreading, giving you
a healthy home, but without the heat loss associated with intermittent fans.
Walls, ceiling, floors & soft furnishings quickly show signs of black mould growth.
What is it and why is it there?
The Vent-Axia Lo-Carbon Response 7 has been designed to meet the requirements
of the Building Regulations for bathrooms, kitchens, utility rooms and
toilets. This fan is designed to run all of the time 24/7, keeping your home
fresh, healthy and free from condensation.
What does it do?
The fan is designed to run continuously at a very low trickle rate and boost
automatically when required. The fan is constantly monitoring the air it
extracts and will boost itself to a higher setting when the humidity levels
within the property reach a certain level. The low running rate means it has
extremely low noise levels – as low as 13 dB(A). That’s quieter than a
whisper! The fan is designed to operate at a lower flow rate than normal. You
will notice it may not clear steam/condensation as quickly as you may be
accustomed, but will clear condensation 100% over a longer period of time.
How will it help?
This fan will help prevent the build up of moisture in your home by removing
steam and odours created whilst cooking and bathing. This will help reduce the
risk of black mould forming on your walls and behind cupboards.
How do I control it?
The fan is fitted with an integral humidity sensor which controls the fan
automatically so you won’t need to worry about any controls. Please note the
fan may run at the higher boost rate as the dwelling dries out this should
settle down once the dwelling has had time to dry out. You also have a manual
switch in the kitchen/utility room to switch the fan from trickle to boost,
you also have a switch adjacent to the light switch for the WC, bathroom, and
en-suite.
Excessive humidity and smells
In extreme circumstances, where there is excessive moisture in the air, or
strong smells are present, there may be a requirement for additional purge
ventilation. The fan will not detect strong smells in the air.
Does the unit require any maintenance?
Maintenance is minimal as the fan is designed to reduce the amount of dirt
build-up. However, to clean the unit the fan’s power supply must be turned OFF
first, then carefully pull the front panel off of the grille upwards away from
the base part of the grille and wipe the inlets and front face with a damp
cloth until clean. Be careful not to push dirt into the airflow sensor.
DO NOT switch off the product
The fan is set to run continuously 24 hours a day, 7 days a week.
What are the running costs?
Even though the fan will be running continuously, you won’t receive a large
electricity bill because the Lo-Carbon Response 7 costs less than 13p a week
to run.
