1. Wiring regulations

Since electric and drinking water could make for a fatal mixture, strict regulations were introduced dividing the bathroom into 4 zones: 0, 1, 2, 3. Area 0 is certainly in the bath. Zone 1 extends vertically 2.25m above the bath. Area 2 extends everywhere for 0.6m from area1 and zone 3 extends laterally for 2.4m from zone 2.

You must install the correct fan in the right zone. Bathroom fans come in two voltages; Mains voltage (240v) and SELV or Security Extra Low Voltage (12v). Mains voltage bathroom extractor supporters may only be utilized in Zone 3 of the toilet. In Zones 1 and 2 SELV bathroom fans (12 volts) ONLY can be used, with the transformer becoming housed in Area 3. The only exception to the rule may be the Airflow QuietAir: A mains voltage bathroom extractor enthusiast that is specifically made with an IP45 ranking to be used in every 3 zones. Inline fans are another special kind of 240v bathroom extractor fan which is housed in the loft space above the bathroom in the center of two lengths of ducting. Because the engine, impellers, and all-electric parts are out from the zonal region, with just the duct and grille in the toilet ceiling, they as well are suitable for use in areas one or two 2 above the bath or shower.

2. Types of bathroom extractor fan

There are two main types of bathroom extractor fans: Axial and Centrifugal. Axial fans will be the ones that you will be used to viewing on wall space and ceilings and generally have air extraction rates of between 85m3/hr and 95m3/hr on the 4-inch models. They are ideal for standard installations where the fan will be ducted through the wall structure. Centrifugal fans tend to be (however, not usually) inline duct followers. (see earlier section). Centrifugal followers are usually a lot more effective than axial enthusiasts with air extraction prices of between 110m3/hr and 220m3/hr on the 4-inch models. Centrifugal enthusiasts are particularly suitable to installations where lengthy duct lengths are needed. The Vent Axia Solo Plus, for instance, can be utilized in duct operates up to 50m!

3. Sizes of bathroom fans

Domestic bathroom extractor fans can be found in two sizes: 4 inches/100mm and 6 inches / 150mm. In nearly every case a 4-inch bathroom extractor lover will suffice. Six-inch fans want only be looked at in bathrooms higher than 3 meters squared, or where particular circumstances need a more powerful enthusiast,...such as bathrooms without organic ventilation or particularly chilly, north-facing bathrooms.

4. Air Extraction Rate

Measured in 'Litres per Second' (L/s) or 'Metres Cubed per Hour' (m3/hr), the airflow extraction rate of a bathroom extractor fan is normally one of the most crucial considerations. The Building Rules stipulate a bathroom extractor fan must extract at least 15L/s in a typical domestic bathroom. Most 4-inch bathroom extractor supporters far surpass this minimum amount requirement, and today the standard is 85m3/hr. Any bathroom extractor lover with an extraction price of 90m3/hr or above could be considered powerful.

5. Operation

Bathroom extractor fans have a variety of operational features to match different applications. The easiest is on/off via the bathroom light switch or integral pullcord. Bathroom followers with essential timers are excellent in bathrooms where huge build-ups of steam trigger condensation complications, as the over operate timer could keep the enthusiast running for a preferred period after it's been turned off....especially useful if the fan is wired into the lighting circuit. Parents may choose a bathroom fan with a PIR sensor that may operate the fan immediately when anybody enters the toilet, whilst Landlords like people that have humidity sensors, which activate automatically when the relative humidity gets to an arranged level. This implies that tenants aren't relied upon to manually operate the bathroom fan.

6. Noise

Common dB measurements for axial bathroom fans range between 35dB(A) and 45dB(A) with the better centrifugal bathroom fans between 40dB(A) and 55dB(A). Whilst centrifugal supporters are louder, it must be remembered they are housed in the loft space and are also insulated and additional away, lessening the quantity somewhat.

7. Aesthetics

Remember: you'll likely see this fan each time you use the toilet. The amount of money you saved onto it when purchasing will be forgotten, therefore don't install an ugly lover because it's cheap. Homeowners are spending more to make their bathrooms gorgeous with cool light and funky fittings and fan designs possess improved immensely. The aged 'box with grilles' is usually slowly being changed with unobtrusive and delicate 'tile' type styles which sit easily with any bathroom aesthetic.
