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,
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
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
When you pick up an extractor fan from your local electrical factors or builder's merchant, you're probably looking at the price. Maybe you'll scan the back of the box, where the manufacturer makes some claims about how fast it can extract air from your bathroom or cloakroom. So if the manufacturer has tested the fan
Vane anemometer? Is it possibly some kind of aeroplane? Maybe a spare part for a helicopter? Do you want one in your tool chest? And why will PEATA lend you one for free? If you spend any time searching Google for "flow rate tests" or "part F airflow tests", you'll quickly come across references to
Clutching a whole penny change from a new twenty-pound note, PEATA was happy to bring the Manrose Gold 100mm Bathroom Extractor Fan back to the test bench. This isn't even Manrose's cheapest fan. As you'd expect from a budget fan, it's not much to look at, but is still perfectly inoffensive. When we did the flow
Perhaps your building inspector has asked for a flow rate test. Maybe you just want to know whether your home has sufficient airflow to be healthy and meet building regs. Either way, you need to know what a flow rate test is! A flow rate test, sometimes called an airflow test, extractor fan test or
