Powersaver offer a range of Ventilation and extractor fans suitable for all rooms in the home. If you are looking for a ventilation fan for a bathroom, kitchen or toilet then we have the ideal solution for you. The 2 main problems relating to poor or lack of ventilation are stale air and condensation.

Stale air can be caused by cooking smells, smoking, odours remaining in the bathroom, a general lack of ventilation around the house as well as a damp atmosphere. All these problems cause an avoidable level of discomfort as well as the risk of respiratory illness and general poor health.

Condensation problems occur when steam from the kitchen or bathroom finds cooler surfaces around the house on which to condense. Attempts to conserve heat by sealing windows - and therefore reducing natural ventilation - makes this problem even worse. Condensation can cause considerable problems from peeling wallpaper and mould growth to severe structural damage such as wood rot and damp.

The Building Regulations Document F1 (2006 Edition) outlines the importance of ventilation and stipulates that mechanical ventilation must be installed in kitchens, bath/shower rooms and toilets. All our fans comply with or exceed current Building Regulations and are capable of extracting the rates required by Building Regulations. This means that humidity is removed at source before it can reach the cooler part of the dwelling and cause damage.

Specific requirements of The Building Regulations Document F1 (2006 Edition) on ventilation are as follows:

Intermittent Fans

Bathrooms/Shower Rooms:

The Regulations require a fan capable of minimum extract capacity of 15 litres per second when installed.

Toilets (Separate from a Bathroom):

The Regulations require a fan capable of a minimum extract capacity of 6 litres per second when installed. N.B. If a room does not contain an openable window the fan should be fitted with a 15 minute over-run timer.

Kitchens:

The Regulations require a fan capable of extracting 60 litres per second when installed.

Utility Rooms:

The Regulations require a fan capable of extracting 30 litres per second per second when installed.

Continuous Fans

Bathrooms/Shower Rooms:

The Regulations require a fan capable of minimum extract capacity of 8 litres per second when installed.

Toilets (Separate from a Bathroom):

The Regulations require a fan capable of a minimum extract capacity of 6 litres per second when installed. N.B. If a room does not contain an openable window the fan should be fitted with a 15 minute over-run timer.

Kitchens:

The Regulations require a fan capable of extracting 13 litres per second when installed.

Utility Rooms:

The Regulations require a fan capable of extracting 8 litres per second per second when installed.

The siting of the fan is as important as the selection of the fan itself.

A fan should always be sited in the furthest window or wall from the main source of air replacement to avoid short-circuiting the airflow. It should be located as high as possible in the window or wall nearest to smells or steam, but not directly above eye-level grills or cooker hoods.

If the room contains a fuel burning device (such as a gas boiler) with a non-balanced flue, it is essential that there is enough replacement air to prevent fumes being drawn down the flue when the fan is extracting to its utmost capacity.

IEE Regulations (U.K.) require that a conventional mains voltage fan in a bathroom or shower must be located where it cannot be touched by a person using the bath or shower and well away from any water spray.

Alternatively, our range of 12 volt S.E.L.V. (Safety Extra Low Voltage) fans are specifically designed for the safe ventilation of toilets, bathrooms and shower rooms and can be fitted within the splash area with absolutely no risk of
electric shock.
