I gave up on standard extractors and instead fitted two in-line fans in the loft. They simply amazing, and have (especially in the bathroom) completely eliminated shower condensation.
@@markrainford1219 Well, we did, Mark, and it's been perfectly fine. The loft is so well ventilated that our timbers are still as they were, 18 years on. I'm an engineer, and I've done a few things that 'can't be done'.
These in wall fan bug the ever loving hell out of me also the ability for people to turn them off cause of the noise my mother was terrible for not turning it on before a shower. Just use a decent in-line fan with hard tubing! dont bother manufacturing them crappy ones, and the cost will go down! If the uk routinely adopted the European standard of heat recovery ventilation, then there would be even less of a problem, we are SOOOO far behind it's not even funny. Conduit wireing for easy rewire or additions is another perfect example of how far behind we are. I could go on all night, but i got a whole playlist to catch up on. 👍
If housebuilders cared enough to pay the extra price for MVHR systems I will eat several of my hats. In my experience they will only do it if the council wants them to meet noise/pollution regs. Being near an airport or motorway, etc. The few times I was asked to use solid duct in a roof was when the site manager knew that plot was getting inspected for an award.
Heat recovery ventilation is still pretty rare here in mainland Europe. They are starting to put them in new homes now, partly because of the new and more onerous EU energy label scheme.
When I fit inline fans and ducting, I put the fan as close to the outside vent as I can. Less pressure to push against and let the power of atmospheric pressure fill the slight vacuum behind.
When fitting a fan with a humidity sensor, never set the sensor to anything below 50% as very often the air will be naturally above this level, a low setting will result in the fan running constantly, generally 75% will be ok.
In my opinion, it's actually best to go for a Heat Recovery Fan which is on all the time. Many have a boost feature which you can activate while you're in the bathroom.
Great video but you've missed the one item that will trip up any casual fan fitment. They are a controlled fitting under B.Regs ie. Building Control must be notified and latest regs says the installation MUST be tested AS INSTALLED, to show it meets the performance required, by a CERTIFIED professional, and results forwarded to Building Control.
Really! What else are building control going to stick their oar in to next. I’m sure we are all going to die if we don’t have a fan in our bathrooms and it’s thoroughly checked by a well paid fan professional. I’m not renting my property, it’s mine. I own it. If building control did what they should then I wouldn’t be spending huge amounts of money to fix the bodge done by the cowboys that built it. Sadly this is still going on with new builds so it’s not like building control are actually doing anything for the money they cost. Provided it’s safe then it’s nothing to do with building control and they can jog on.
@@davideyres955 I feel like that. We had a wood burning stove, but didn't tell anyone (and it didn't go into a liner, either), and in my bathrooms, I have normal light switches, not pullcords. My house, my rules.
Nice presentation, however I mis the notice of the supply of air in a (bath)room. If you want to suck out moist air, you need to to supply fresh air. Next if you live in a area with lots of bugs like 🦟, take a vent with a filter or beter with flow-shutters etc.
@@srpacific houses in the UK are generally very cold and inneficient. Power is very expensive (especially in the last few years). Many want to sacrifice poor ventilation for warmth.
Tbh I think 4 inch (or "100mm") fans are pathetic, I'd much rather have a 12 inch (or "300mm") and with adjustable speed. Admittedly what I came across was in a kitchen not a bathroom, but about 17 to 20 years ago, a family I know lived in the most random old-fitted-out "multi-storey house above a shop" ever (sadly since converted to boring flats) with a weird random layout and multiple bathrooms (one leading into one of the bedrooms and another leading into the laundry room), and the kitchen had a 12 inch (or "300mm") Vent Axia T-series wall extractor fan, yes in a domestic house! I can't see why one couldn't be used in a bathroom either?
Best would be to replace the fan by a whole house ventilation unit with remote control/humidity sensor and have it ramp up when necessary, and never have it turn off. Also, remember that the air needs to come in from somewhere otherwise you're just making a vacuum!
@@efixx Correct, and it also adds some bends too. Not to mention retrofitting whole house recovery... Easier to build a whole new house almost if it's entirely brick and concrete. That aside, this video intrigued me to replace my fan. It's a cheap design model but the amount of cubic meters per hour compared to the decibels it made it seemed quite on par with premium models. I should definitely look into one for myself. In fact, it also seems that the manufacturer is listing the cubic meter airflow for covered design fans without the cover plate installed while they are obviously meant to be used with the cover. Shady marketing.
Ah please! Envir-o-vent? Anyone in continental Europe will tell you that S&G fans are 4 times more efficient and twice as quiet. This is simply because they turn their fan blades around 90 degrees to all of the other manufacturers. However i admit there dip switches are far to complicated for options. And yes, solid duct should be mand if you look at the maths.
Insightful knowledge. The title of the video was the shocking truth about extractor fans. I have found little shocking facts from this video. What aspects are shocking or highly insightful about Extractor fans. Why I have found shocking is that simply opening a window to ventilate us much more effective in managing a humid or condensing environment in a bathroom. My vision is that bathrooms in homes today are simply designed inadequately and a extractor fan is simply a symptom of a design flaw. Would like to hear if there is any truth to this. I have always found duct fans limited in their functional and capacity. I have had a loud extractorfan installed because of building code. The bathroom is built on an I terror facing wall, with no wall being next to or an exterior wall. There is all this refined and quasi placed ducting to manage a ventilation system. The problem I see is that the fan does pull humidity and condensation, bit there seems to be an area of static area across from the ventilator that does not clear quickly. While all other walls are dry quickly, the furthest wall stays condensates for a while even at maximum ventilation rate setting. The radiator fan border the door, which has a open slot at the bottom for ventilation. What I see happening is that there seems to be a strong air flow from this slot to the extractor fan. I can clearly feel as air flow from this slot to the fan box. The rest of the bathroom seems stale in airflow. This has given me an impression that likely an extractor fans performance is perhaps also only as good as the way a bathroom is built and in which spot the ventilator is actually placed in the space. If I could choose I wouldn't want my house dependent on an electrical system but rather gave natural ventilation. Is think this would leave us less dependent on energy consumptive technologies and maintenance and perhaps unnecessary overhead cost. Electric does have its conveniences. But in a world where the is increasingly designed to cater for elictric systems, which come with priveleges, but also obligations (which are often glanced over), makes me more excited in the current climate to thonk of ways to passively ventilate a bathroom rather than being dependent on more costly active systems. I am curious to know if others share this view in this energy transition zeitgeist and what similar or more refined ideas people may have.
I’d suggest you checkout our CPD on ventilation and the building regulations. As buildings become more airtight and insulated the requirements for properly designed ventilation increase.
Envirovent is premium? I have one of those pieces of trash keeping me up every night.. the bearings are made of beach stones.. at least that's my best guess based on the sound
Good informative video. The fan in my bathroom is on the wall & leads straight outside. It is 20 years old, noisy and only works with the light on. Is there a better option and are they easy to install?
Humidistat fans are your best option, but if you don't know what you're doing, you should get a qualified electrician to change it. Should be simple in theory, but if any problems come up then the experience will be invaluable.
@sparking2016 Once fitted a humidistat fan and it would turn off and then not restart. Turned out the heat from the dropper resistor would desiccate the sensor 🤦♂️.
Like fighting a uphill battle. Apparently when I have the NICEIEC do our assessment for ventilation we are the only company in a huge radius. We sign off all new installs with a certificate and notification to building control. Bloody no one does it, no one does it right it’s a joke. Maybe add the ventilation course on to the apprenticeship course just to give some basic knowledge on the subject
Cause we are fed up being scammed and paying to work for marketing companies like the nic.... im either qualified or im not, paying to be * member* is a scam, really is. Just do what everyone else is doing, notify nothing.
@ agree with the “scheme cough cough scam” but it’s doing a course be it at a college or even at a manufacturing company it gives a better understanding of what should be done. Also using a dedicated tester to commission the fan will give you an idea if you have installed the correct unit for the space. I have seen so so many piss poor installs for Ventilation it’s a joke. Provides me with lots of work which is good but not good for the customer. Should not be having to pay twice for dumb installers. Like I said if basic installation methods and basic regs were taught in the electrical apprenticeship course it would help with what the video is banging on about .
Half the problems I had were that builders would insist on underspecced fans and then complain when I failed their fan tests. Company told me to fudge the numbers to make them pass. I wouldn't put my name on those certs and eventually left.
It was only a matter of time before you had an onlyfans episode.

Yes, I did that 18 years ago when we moved in...but be sure your loft is well ventilated, as you are sending damp air up there.

Putting moist contaminated air through a system with filters is pointless

Great tip
If only architects paid attention to that idea and roofers didn't occasionally forget the vents and install them near the apex :)
I always had this in my mind but never looked into it. It's a great idea, although not always works out .

140mm 12v brushless PC fan, thermostatic speed controller, 12v psu -sorted. much quieter, more air flow and only runs when its actually needed.
Easy to replace when the bearing goes bad too! Commodity components ftw
I used to be a tractor fan, but not anymore.....
Boom 💥
A fan isn't just for condensation in a bathroom with toilet. So humidistat isn't suitable in such areas
Humidistat versions also include switch input so do cover all “problems”
