Mould can be a major problem in any home during the cold winter months when people spend more time indoors, and the cold temperatures outside make condensation on windows and exterior walls more common. Landlords have a responsibility to their tenants to provide a quality living space and must take steps to prevent mould as it can be damaging to health.
Rented properties create specific challenges in the prevention of mould, as it is not always possible to inspect the home to identify a problem before it becomes serious. As such, installing effective ventilation in the property is essential.
Extractor fans are devices that remove moisture laden stale and humid air from a room so that it can be replaced with fresh and dry air. With a single extractor fan, this air is drawn from elsewhere in the home. The lower air pressure from an extractor fan will draw fresh air into the home through vents and ensure that the air circulates through different rooms to. Extractor fans should always be installed in bathrooms and kitchens and other wet rooms such as WCs and utility rooms, where most of the moisture is generated.
Extractor fans can help to stop mould in rented homes several different ways:
There are different types of extractor fans available, such as axial, centrifugal, or mixed flow fans. They can also vary in size, power, noise, and features. Some extractor fans have timers, sensors, or switches that control when and how long they run. Some extractor fans also have heaters, filters, or lights that enhance their functionality and performance.
The EnviroVent Cyclone 7 extractor fan features a moisture sensor that detects the humidity level in the air and adjusts its power level accordingly. This means that it reduces the amount of water vapour in the air of a bathroom much more quickly and allows it to work more efficiently over time which can help to reduce energy use.
The effectiveness of extractor fans depends on several factors, such as:
To get the best results from the extractor fans that are installed in your property, it is important to consider where and how they are installed, as well as ensuring that they have sufficient airflow to cope with the environment where they are placed. The minimum extract ventilation rates for intermittent extract systems are as follows:
When planning the installation of extractor fans in a home, a specialist will be able to be advise what type of fan is required based on the size and layout of the rooms, but fans should always be installed by a qualified electrician.
Extractor fans are not a magic solution to mould and damp problems in any home. The residents need to ensure that they are correctly used and that any excess moisture is removed from walls and ceilings.
Tenants should avoid drying clothes indoors where possible, and open windows each day to allow fresh air into their homes. Extractor fans should always be used when cooking or bathing, and left running for at least 15 minutes after use.
Ensuring that your rental properties are well ventilated helps to prevent condensation causing problems with mould and damp that can affect the health of your tenants as well as damaging the value of your property.
