Extractor Fans Always Advised For Ventilation!

Whenever a shower is installed it is always advisable to fit an extractor fan to remove excessive water vapour and condensation. This is especially important in rooms without windows or en-suites where the moisture-laden air may cause discomfort if not removed.Effective ventilation is now a primary consideration in the design and construction of all buildings. Greater use of sealed heating systems, double glazing, and increased insulation combined with the moisture created in kitchens and bathrooms, makes efficient ventilation a high priority.An experienced and qualified plumber will need to assess correct extraction rates, the power and correct placement of the extractor, establish the source of return air, take into account energy saving issues and the correct choice of ducting through which air must flow efficiently. City & Guilds NVQ Plumbing training through the different levels at AbleSkills will provide the approved knowledge and practical training qualifications designed to handle all types of daily domestic plumbing issues.One of the main problems that can reduce the efficiency of an extractor fan is poor placement. A fan should be installed in the furthest window wall or ceiling from the main air inlet point and at a high level. This will ensure maximum airflow of fresh air throughout the whole room. Internal grilles in the door, ceiling or wall will provide sufficient replacement fresh air.Most bathrooms will be fitted with a through the wall extractor but a shower enclosure, or a shower in a confined space e.g. basement will require an in-line extractor which can extract the moist air over a longer distance.The extractor fan can be turned on via a pull cord, which must be beyond the reach of anyone using the shower, a humidistat which automatically turns on when needed or a switch connected to the lights. The latter is usually used in rooms with no windows and is a building regulation requirement. IEE regulations require mains voltage fans to be positioned out of arms reach of the person using the bath or shower. Mains voltage fans and controls should also be sited away from potential water spray.If installing a fan in a room containing a fuel-burning device, which has a non-balanced flue, there must be sufficient replacement air to prevent fumes being drawn down the flue when the fan is on maximum extract. Exhaust air must not be discharged into a flue used for exhausting fumes from appliances supplied with energy other than electricity.Do not site fans where temperatures are likely to exceed 50??C, or above a cooker hob or eye-level grille. Wiring should be carried out in accordance with current IEE Regulations (UK). Ensure that the instructions provided are followed during installation, with particular care taken to check the supply voltage, fuse rating and wiring are correct.
