Husky Vac Ireland are providers of whole house ventilation systems which will provide clients with a comfortable, fresh and healthy environment, whilst continually saving them money. Heat Recovery Ventilation Systems (HRVS) recovers the heat energy in exhaust air as it leaves the building and transfers it to the fresh air as it enters the building. Efficiencies in excess of 90% are guaranteed, meaning that the fresh air being supplied is virtually at the same temperature as the air being exhausted. It works by extracting the warm, moist air from rooms such as bathrooms and kitchens where condensation is a major factor. The unwanted air is passed through a heat exchanger then ducted to outside. Fresh air from outside is drawn in and passing through the heat exchanger; recovering up to 90% of the heat taken from the extracted air, it is then ducted throughout the house encouraging positive air circulation.
Why do I need Heat Recovery Ventilation?
Ventilation is essential in modern well insulated homes, not only to prevent the very visible problems associated with moisture generation, but also to provide a better indoor environment free from atmospheric pollutants with ample fresh air for healthy living. Mechanical Ventilation with Heat Recovery (MVHR) provides the most effective method of achieving energy efficiency and adequate ventilation.
The key to efficient living space ventilation is controlled and balanced airflow. Traditional ventilation methods in the home rely on some form of extract to remove the moist air and pollutants, generally an extract fan or passive ventilation duct installed in the ‘wet’ rooms, where the water vapour is generated.
The extracted stale air must be replaced by fresh air from outside and this is normally achieved by natural leakage through openings in the building structure and the installation of trickle ventilators. The provision of these replacement air openings means that the ventilation rates cannot be controlled with wind pressure and direction varying the air flow, as a result the air change frequency may be as high as four or five times per hour but not necessarily in the rooms where it’s needed. Far higher than the one air change per hour generally accepted as the optimum level to maintain a fresh atmosphere in the home.This over ventilation achieves no gain in resident comfort but certainly wastes energy and causes potential occupant discomfort due to draughts.
Condensation is the most visible effect of inadequate ventilation. Streaming windows and puddles on window sills are a common indicator of moisture build up. On average activities such as cooking and bathing mean that each person in the home produces four litres of water vapour per day. Unless this moisture is removed problems soon occur. Not just the inconvenience of wiping surfaces dry but the greater, potentially expensive, problem of mould growth ruining decoration.
Even the fabric of the building can be at risk if the condensation problem is not addressed. But condensation is not the only problem. A poorly ventilated home can mean the build-up of harmful gases. Building materials, paints, furniture and carpets all give off gases which can be detrimental to occupant’s health if not correctly dissipated. In some areas of the country the poisonous gas Radon can add to the potential increase of unhealthy pollutants. Modern airtight construction can mean a stale musty atmosphere high in carbon dioxide tainted with the odours produced by our everyday activities in the kitchen or bathroom. Altogether an unpleasant household environment!
Other health issues include the dust mite, a minuscule household insect that is a major contributor to the increase in Asthma cases. Dust mites thrive in moist conditions resulting in increased numbers with a corresponding rise in suffering. House dust mite allergy is very common and is associated with asthma, eczema and perennial allergic rhinitis. A significant amount of exposure to house dust mite allergen happens in the bed, so taking precautions in the bedroom by using allergy-proof covers on bedding, washing it regularly can sometimes help, although clinical trials suggest that multiple measures need to be taken, possibly including the use of chemicals called acaricides, in order to see an effect. However, remember that dust mite allergen is found in all rooms of the house, on the floor and in soft furnishings, not just in the bedroom hence that’s why you should consider talking to Husky Vac Ireland about an appropriate vacuum system to suit your needs.
