    Condensation - Home Ventilation Fans

    Humidity control is rapidly becoming a priority maintenance considerati­on for landlords, councils and home-owners. Damp and mould are the blight of many UK households that have insufficient heating or inadequate home ventilation to stop condensation and mould.

    As condensation is formed from airborne water vapour, expelling the humid air is a vital step in reducing condensation levels.  Correctly addressed ventilation will combat most condensation problems by replacing moist humid air in the home with fresh air from outside the home.

    Window openings and open chimneys have historically allowed a building to breathe and supplied sufficient airflow through a building to get rid of excess water vapour.­  Building Regulations now call for more energy efficient and airtight houses and flats, most with sealed double glazing, central heating and no open chimneys. Accordingly passive ventilation now requires greater design input to allow the home to breathe naturally.

    The three most common types of home ventilation are:

    • Positive input ventilation
    • Heat recover ventilation
    • Passive ventilation

    What is positive input ventilation?

    Positive input ventilation works on a different principal to extraction ventilators. It supplies a constant input of fresh clean air into the home so that the positive pressure indoors is greater than that outside. Nuaire ventilation fans gently supply fresh and filtered air from a ventilated loft or an external grille.­  The positive indoor air pressure that the unit creates displaces humid, stale and contaminated air, forcing it out of the home, to reduce the risk of condensation and improve indoor air quality.
    What is heat recovery ventilation?

    Heat recovery ventilation, also known as HRV, is an energy efficient mechanical ventilation fan that both expels humid, stale and polluted indoor and brings in fresh, clean air from the outside. Generally used in areas of high water vapour generation such as kitchens, bathrooms and laundry rooms, heat recovery units use a heat exchanger to transfer the heat energy from the outgoing air to the fresh incoming air, recovering 80% of the heat energy.
    What is passive home ventilation?

    The windward side of the building has greater positive pressure than the leeward side.  It therefore follows that if vents and floor plans are orientated ap­prop­ri­ate­ly then it is possible to ensure air flow travels naturally in through the windward side of the building and out of the leeward side without mechanical assistance.
    Radon Fans
    What is Radon?

    Radon is a colourless and odourless radioactive gas that occurs naturally in the ground. Produced by the decay of uranium in soil and rock, radon gas naturally migrates from the ground into environment and can accumulate in buildings. It is the second leading cause of lung cancer and is responsible for around 2,000 lung cancer deaths in the UK every year.
    Is my home or business affected by Radon Gas?

    Radon is everywhere but some parts of the country are more likely to have high levels in buildings than others. The radon level in the air we breathe outside is very low but can be much higher when trapped inside buildings.  Public Health England publishes a UK Radon map showing areas most at risk of Radon conta­mina­ti­on.
    What is Radon Ventilation?

    Home ventilation systems can be used to extract excess radioactive Radon gas from buildings. Radon fans are used to extract the gas from a Radon sump formed beneath the building.­  The fans pump the gas from the sump to the environment outside of the property to reduce Radon con­ta­mina­ti­on levels.

    Twistfix supplies a range of Nuaire positive input ventilation fans and Stadium heat recovery units to manage home ventilation and stop condensation effectively. We also supply Radon mitigation fans across the UK  reduce harmful radioactive gasses.
