Ventilation can be tested using a number of different types of equipment. They each have pros and cons, and each is useful in different environments. Here’s a list of the main ones: Hotwire anemometer With no moving parts, these can be very robust. They work by heating a wire to a known temperature using electricity,
In our previous article, we looked at a couple of different ways that intermittent extractor fans can be controlled. These are the fans that you regularly see in bathroom walls or ceilings, and hopefully keep your bathroom or cloakroom fresh and dry! If it's not - if the bathroom is damp or smelly - you
It's all very well having an extractor fan, but what controls it? How does it decide when to come on? How does it know when to turn off? There are several options, and they all look pretty similar from the outside. In previous articles, we’ve talked about why extractor fans are important, and how much
As well as being unsightly, black mould - usually found in the corners of rooms, near windows, or at other "cold spots" - has been linked to a number of health conditions. If left unchecked, it can cause serious damage, perhaps even structural. Even if it is regularly treated with a proprietary spray, the spores
Like drainage, hot and cold water supplies, and electrical cable runs, ventilation ductwork benefits from a bit of forethought. Unfortunately ventilation is often left until the last minute - just stick in a cheap extractor fan and a bit of Flexi at the end of the job. Unlike drain runs and hot water, it's not always
The 2010 (revised 2013) version of Part F of the building regulations, details the specifications required for extractor fans in domestic premises. It also specifies when and how to do airflow tests, and that (under most circumstances) a Commissioning Notice is required. A Commissioning Notice, also known as a Part F notice or PEATA Certificate,
So your Building Inspector has called the client, and the client has called you. Where's the Part F Commissioning Notice? Did you do an airflow test? Have you completed the certificate and the form? Flow Rate tests, also known as Part F tests, PEATA Certificates and Airflow Tests, have been a requirement of the Building
So you need a ventilation commissioning certificate. Perhaps an airflow test certificate, or Part F Commissioning Notice. The building inspectors wants one, and the client wants you to make it happen. Luckily, here at PEATA, we try to make your life easier. No-one wants to spend time filling out forms and generating paperwork when they
Let's be honest, the first thing most of us look at when we're picking up an extractor fan is the price tag. Particularly if we're on a price and the client hasn't specified anything fancy, we just want something that is going to get the job done. So why is there such a range of
To be honest, we thought the Manrose Gold 100mm Bathroom Extractor Fan that we tested before was pretty good value - if a little noisy, and not much to look at. The Manrose Standard 100mm Bathroom Extractor is the even-cheaper little brother. This fan isn't going to win any prizes for it's design. It's chunky and
