quacking good yarn
Hi Robin, really enjoyed this and so glad you state all the parts, manufacturer etc. It really helps the rest of us for research - so ignore the "advert" comments.
Some of us are too busy to find out about these excellent products & rely on informative videos like this to learn from.
Thank you.
Regards
Tim
Thanks Tim,
Very true !
Hi Robin. How no noisy is the unit / vents when it's running?
Excellent presentation, installation,,great job guys!
Instablaster.
Awesome product and a awesome job! Well done Robin.
Loving the Capel build keeps it up guys!
Another informative, educational & inspiring video - brilliant work!!
Brilliant work Robin!
Excellent video. Many thanks.
quality as always, well done Robin
Beautiful work! Thank you for the video!
I'm loving the specs of this build. Quality work.
A modern solution for a modern building. Definitely the way forward. Great video guys. And, as per usual, the thought and prep that's went into installation resulted in an asthetic and efficient system. Expect nothing less from robin 👌
Thanks you John
Mircea I think ur right, there should be a proper filter like the ones inside, would it not help with the intake and output so close together too.
Hi, I have been watching the CAPEL BUILD from the start and am blown away by the attention to detail. I'm a carpenter joiner by trade and love to learn about all the new in innovations in home building that are out there. Thank you for putting this valuable content out there. I really appreciate the amount of effort your channel puts into being real, honest and professional.
Thanks again
really excellent video Robin, well done,top job!
what a peaceful educational video. Love your personality mate.
Imagine the size of the container you’d need to house all of Robin’s handy little templates!
Great video. Thanks for posting
That place looks amazing keep it up
What an excellent video and clear explanation. Thank you. I get the impression that this is really a system that you need to install yourself. Robin took such a lot of care to make sure it was a good job. It would be difficult to find anyone that would do it to this high standard. To see how everything runs through the building, well, it’s almost like a piece of fine poetry. Well done!
Thanks for your comment David..
This has been an amazing watch, I’m starting a new job which is completely new to me as an MVHR designer, and I’m learning all about it. This has been a great video to show me what goes into installing a system
Robin you are a what I can only describe as a construction geek! Your attention to detail and consideration of every element fitting correctly is brilliant. Its a breath of fresh air.
Fresh air. Where? Lol
What a great video. Thank you very much
Excellent video, really enjoyed that, cheers mate 👍🏻
Your welcome Ted
I love MVHR systems and i cant wait for it to become a must with building regs
Aye, especially after those two reports came out showing trickle vents and DMEV systems don't work
Theyre now going to become the norm with the new part L, F and L regs our this year :)
Skips to 23:53 and see the ghost on the top right corner. What the...
If you look close, it looks like a monkey.
Great video, cheers
Excellent video , very informative. 👍. Great product as well
Hope people can learn from this how important airflow is to a structure.
Another great video, more please.
Not as important as it is to humans ! Super airtight house, you'd suffocate. : )
That was really superb; a logically crafted instructional video production.
You guys are compulsive viewing on everything you present, thank you.
You only mention bathrooms for extraction, but surely ideal to connect a (pre-filtered) duct from the cooker hood as well, perhaps electro valve switched with the cooker ?
EXCELLENT EXPLAINATION...
Hi, I'd be interested in a video that discusses retrofitting MVHR into a typical 80's brick and block house. I saw the loft condensation video hoping it would cover it but it didn't go that far.
The 80s house is air tight?
I doubt it. Wouldn’t that be one of aspects to address among many other factors?
Giday Robin, thanks nice nice work , Cheers from AUS.
Hello there! Rod I hope you are not in lockdown.
I like the way you let the rain go through a bird mesh into the horizontal spiral 19:30
Loved this, many thanks. Been teaching building services for years. A great practical demonstration of how it works and how to install it. Hope you don’t mind but I’m going to put a link to this in the learning environment for my first year construction and surveying students.
please do. The more views the better
Great vid, these systems haven’t changed in 30 years really since I was installing these for Johnson & Starley, they are just more sophisticated, truth is though they work great and if you have a dampness issue they cure it.
Another great video Robin. Ideally you should seal the ducts after first fix. Not every joiner uses a dust extraction system like you do and this prevents harmful building dust contamination of the ductwork. If people are considering retrofitting these, I believe MVHR suppliers recommend a minimum air tightness of 5m3/(hr.m2)@50Pascals otherwise there is excessive leakage via the building fabric, making the system less effective
Was just wondering about installation mid renovation work 👍🏼
Fantastic video chaps! I’ve a 15 year old Mvhr system and been recommended to upgrade. Learnt some quality extra information from vid, thanks. Would love to go with similar system but think pipes will limit me to staying with same brand.
If you're going ahead with that, just be wary that the pipes don't affect the system by creating pressure drops which will decrease the efficiency and increase the noise. You could have the most efficient mvhr going but if you put shoddy ducting (PVC/flexible) in then it'll be rubbish
Sounds great but extremely expensive. Love the videos👍👍
Hi Rob, great video. Do you plan to insulate the ducts to outside to avoid condensation forming on them? Also have you fitted any silencers between the unit and manifolds?
It would be interesting to know if an airtightness test was ever done on the build in the end and what permeability was achieved ? Thanks 👍
Nice to know that amongst the cowboys the industry is served with skilled professionals too.
Top Vlog..👍
Brilliant explanation of mvhr units and what they do! Great system too. Questions. What are the flow/extract rates @ litres per second. What is the air tightness target for the house? Passive house?
Neat system. I wonder how much energy this actually saves. And the boost mode should be energized by the shower light switch; wouldn't be too much trouble to add a small 2 conductor cable zip tied to the return pipe and over to the control panel. But boost scheduling will be decent for set schedule homeowners. GJ R&R
You should avoid triggering based on light switches as that is incompatible with smart bulbs.
Better to trigger based on sensors like humidity, or connected to the smart lights.
Great Video Guy's
Quality install, we love the attention to detail, the coarse you went on is a big help i bet to understanding the install and operations of the MVHR, will you now become an NICEIC registered installer.
Great quality build.
Hi the course I completed was The BPEC course it was a really good course and I learnt so much, thanks for the comment and also the comment on my staircase video, oh your channel looks interesting some watching for me tonight!!
Robin Clevett Thanks Robin that means a lot to us, it’s early days for us but we are all enjoying the experience.
Have a wonderful Christmas and New Year 👍
Regards Tony
Wowsa!
That seems like a great air handler. Maybe a squirt of silicone spray on those rubber gaskets would slip in and out with a bit more ease.
Very informative, thank you. Very neat holes to exterior but the metal ducting is "one big thermal bridge". Any ideas on how to get around that?
Really informative video and beautiful installation as always! Can anyone tell me what accreditation’s an installer would have to have to commission a system like this with regards to UK building regs. It’s something I’d be interested in offering alongside my electrical business?
To reduce noise from the unit the mass of the mounting wall should be much higher than this stud walk. It might even emplify the noise.
Hi Robin, Love your videos, please keep making them. Couple of questions for you regarding MVHR, I am just about to fit a similar system (Blauberg unit + Lindab 200mm spiral duct) and was interested to know why you don't seem to be using any mechanical fixing of the the ducting (self tappers or pop rivets) as recommended by Lindab and also why you don't have any silencers on the house side of the MVHR unit?
Hi Robin. Really enjoyed your video as an insight to MVHR. I've been working with this kind of stuff for many years as a hospital mech tech and understand all these principals. The only thing different, is that a huge catering kitchen as in a hospital has direct extraction to atmosphere via hoods over the cooking appliances. How would you incorporate this in a domestic setting. As a hob or oven gives out a huge amount of wasted heat, how would you incorporate this heat into the domestic MVHR system without the risk of cooking odours and above all, grease, oil and steam contaminating the main filters, ducts etc and permeating throughout the house? Many thanks. Derry.
Grease tends to ruin the heat exchanger.
Vent direct and have make up air imo.
Filter hood with carbon filter can go a long way
What air flow is this unit? To what m2 of the building. I am trying to find best solution to my new build.
Great video. You got yourself new fun👌🌟
Why is it ghostly apparitions appear in your videos. Its happened a couple of times now 23mins 53secs, top right corner. Old guy with a beard. Great video as usual. Very informative.
Thank you for the video! What is area of the house?
Hi Robin, great video, thanks. Perhaps a rude question, but how much were the components for the system? Fantastic detail in your explanations. Love this channel. Thanks.
Im looking to fit mvhr to a self build soon but wondered, them wooden supports you fastened up, do they require anything to prevent the ducting vibrating against the timber, like cushioning?
Great video. At what point did you cut the plenums to length and how did you do it.
Hi Robin
Great video!!
Can I ask why you chose the Blauberg unit as apposed to the Vent Axia units Lindab offer.
Huge thanks in advance
Robin thats fascinating great vid. Can you tell me what earphones you have around your neck ? Cheers
Help!
I have an early 18th Century terraced cottage. It's roofed with thin Yorkshire stone, typically 15 to 18mm.
It's the original roof, most of the lime mortar and timber fixing pegs are in place but I have a number of cracked slates.
I've had a number of reputable local roofers out and they are all reluctant to go onto the roof. They think that they will probably do more damage just by putting ladders onto the roof,
If I reroof, I have to use the same slim slates so that they match the houses either side. There's also the issue of getting hold of enough slate to do my roof. I'm getting quotes of £10K to £15K just for the stone to do one side. It seems that the quarries don't like cutting thin slates, they get get more breakages and it wastes precious stone.
I'm considering having closed cell PU foam sprayed on the underside. The foam is from BASF and is applied by their approved contractors. Price is about £5K
What are folks views on this sort of application?
Awesome video! Thanks
Does the unit separate the moisture from the warm air coming from the shower? Like a dehumidifier ? Ie it has a water catchment or hose that leads to the drain
If the unit was loud would u consider building a sound proof box around it ?
How does it deal with smell of the toilet ? You don't won't that smell distributed around the house haha
So basically to have a healthy house you first make it water tight then air tight then control then control the air inside? Is that how it works kinda like aircon in a car
It takes the warm smelly air from the bathrooms, passes it through a heat exchanger, then vents it outside, the cool fresh air from outside is warmed in the heat exchanger and sent to the living rooms, so no, it doesn't distribute smells within the house!
You can get either a enthalpy heat exchanger which puts the moisture back into the house (usually used in large houses with only a few occupants so the air doesn't become too dry) or a regular heat exchanger which takes the moisture out with a condensate pipe attached to a drain. Don't think the Mvhr he's used has that option though.
Daniel Payne ok just googled ....Ideal in-home humidity levels should hover around 45%.
Anything under 30% is too dry, over 50% is too high.
Really interesting. Just one question. As the air extracted from the bathroom will contain a lot of water vapour, is there a risk that it collects in the steel duct when it cools and condenses?
Robin, does the system detect moisture, say from a shower, in trickle mode automatically speeding up to boost mode and then automatically drop back to a trickle again when the moisture level has dropped back down?
Don't know about his but you get some like the Zehnder CAQ series which do. I've heard of some which go on a timer, but personally I'd rather have one that boosted until the humidity was gone instead of when the timer ran out
I worked in a pub where they put the output to the ventilation from the smoking shelter next to in air intake to the kitchens. Oops. The kitchen smelt like a wet ashtray for weeks.
Hilarious how they could get that wrong.
Hi Robin, what render is on the Magply board ? I have a 460mm fascia and don't want to use plastic, the Magply board might be what I need . Ideally I would like to but join the board , scrim tape the joint and roll some kind of render or finish on the board that doesn't cost an arm and a leg to buy. Any ideas would be most welcome. Thanks .
Really good video, just one question as you have underfloor heating would you get condensation in the plastic ducting ? as it would be relatively cool in that space with the type of heating you have
Without looking at the build, I am sure if you can get the duct off the MVHR to run through the timber frame as you could get it to the manifold and have shoes off your 200 dia good big to each room. Not a fan of flexi duct would of run it all in solid and the safe fittings aren’t as good as portrayed. Duct seal is better. Also mounting the unit on cantilevers with anti vibes or dropping rods from timber is much easier to level of and reduce vibration and noise
Great video Robin, with Roger in the background this time. You guys are amazing.
Thank you for keeping your promise to produce a video on MVHR and Cheers for that. Been waiting for months.
Qs. Most of it, maybe Lindab can answer.
If I were to be using this system in a hot and humid climate with air conditioning to cool the house, the same system should work right? I ask this because there is always talk of only heat recovery! I guess simple principle of physics should hold true for cooling recovery as well. Just asking.
Second, do you have longer version/footage on the plastic ducting through bends and walls and awkward turns? That will be useful, particularly the fastening/clips part for installation.
Third, what about a multi level concrete house; concrete floors, walls, ceilings.... Duplex or Triplex. How will the ducting work?
Fourth, How do you do sizing of the unit? How does one determine the inward/outward pressure?
Fifth, What about timers? Is the system on all the time? Or can you set it to work for 5 mins, or so, in an hour so it effectively works for about 2 hrs in a day!
Just asking. Please let me know.
Rajesh Iyer couple of answers for you. The size of the system is determined by the size/volume of the property. The system is on all the time . It Can have automatic boost or manual.👍
Hi RajeshCooling options are available to temper air temperature, not all MVHR systems provide cooling however even without, the fresh air can make a room more comfortable. We don't have a video of any longer examples of the ducting unfortunately however we can advise on any individual project. Without seeing the specific design of the building it is difficult to advise on the ducting requirements for duplex, triplex or multilevel houses with concrete walls and ceilings however, we have a solution for most applications and could provide advice relating to a particular project with more detail.Again, each unit is sized upon assessment of the requirements of the individual projects and a variety of factors are taken into account such as the volume of air and the preferences of the client which can be discussed at system design stage. The air flow levels can be set at commissioning stage. MVHR systems can be set to run on timers however they are designed to run all the time at a minimal level which maximises efficiency and provides a comfortable air quality. Please feel free to email residential@lindab.co.uk if you would like to discuss further.
Can you add extra cooling to this system, modern houses if south facing can get extremely hot?
The first valve you fitted had 2 spigots is that to loop to the next valve ( obviously not a return) if so, how many times can you loop into a valve. I take it this can also be done on a return extract run?
Assuming you mean the plenum (the metal box the valve pushes into) ; this is to prevent too much air flow going down the one duct. For the 90mm ducting he's using you wouldn't want more than 30m3/hr per duct as it'll just increase pressure drops and noise. With the Octopus system he's using the plenums are connected to the manifold only, so you wouldn't have ducts running to one plenum then onto another.
I’ve just bought a property in Portugal west coast. It suffers from most of the expected problems with older Portuguese builds, (insulation, humidity, mould etc). I am getting the outside of the house insulated, but I am still looking for a solution (as ‘eco’ as possible) for both heating and ventilation. I’m now 100% sure that a MVHR setup would be perfect for my ventilation requirements, however, I am still unsure why these systems cannot be integrated with some form of efficient heat generation as well as already ‘recovering’ heat from wet rooms? The house has a wood burning fireplace in the living room, but I don’t believe this can be used to introduce heat into the ducting system. Are there other options for heating the air being moved around?
Hi robin I noticed you didn't insulate the external vent pipes. Were you advised to? As I would have thought bring cold air into a thermally sound house through steel pipes would produce condensation!
Hi Clive, although not shown in the film the supply pipe to the unit and the extract pipe from the unit where fully insulated between the unit and the outside for exactly the reason you suggest, hope that helps many thanks for your comment
Anyone know hat happens with condensation in the ducts, does it drip away or evaporate, do ducts need drainage angles at any point?
Another great video, I suppose you can only install that system if you’re using those joists?
Hi Steve, if you plan your initial house design well then you can use this with traditional joists in some larger new builds the may have concrete 1st floors and they fix the dusting to the underside on the floor and it is hidden by dropped ceilings
Robin, I have a wood burner in the living room, when it’s on the living room gets very warm but doesn’t really get to other areas of the house very well so I feel like allot of the heat is wasted a bit, would this system be able to direct the hot air from the living room to other areas? And have it set up as an extractor in the bathroom? Another great video as always, really enjoying your build.
There is very strict rules that surround the use of wood burners and a whole house ventilation system, I was planning to have a wood burner but the device needs to be room sealed and it takes its air from a duct directly from outside, only about 5 percent or less of available wood.burners are totally compatible with MVHR, we have opted for a room sealed gas fire as the look we want to achieve was so expensive with the equivalent wood burner that it became ridiculous!!! Hope that helps
This guy should be the prototype of every so called professional installers.
Minute 19:22 my only concern is the way the plates were notch to run the duct.
There is no real load there. The roof joist run the other way at this point
How does the unit handle the moisture removal? Is there a catch can?
Hi Miles the unit is plumbed into the drains with a condense trap great question mate
Hope you got that at a very good price robin as you have just sold it to me
Hi. What was the airflow meter called? The cone you put up to the ducts? Did you then pair it with the phone a standalone unit to read the measurements? Thx and great video
It's a Testo 417 anemometer
So does this provide the heating for your house or do you still have a separate heating system.
Great video! I m a Lindab fan also. Nice to see other products to potentially use for future projects. Btw what brand are your winbags? Look decent
These where from Lidl they where about 8 pounds for the pair!!!
Robin Clevett thanks! I ll keep my eyes peeled 👍🏻
How do you measure accurately for the position for outside hole? Whenever I encounter this problem things never line up despite seeming to measure multiple times I am off!
use a pilot drill and you can then adjust the position if you are a little bit off.
Not seen any in Aberdeen yet .dose the ducting need insulating to prevent condensation ?
Great question... if any ducts are not within the insulated envelope of the structure then yes, the main extract air and intake air ducts need insulating away from the main unit too, thanks for the comment
Top notch install, as expected . I've always been keen to fit this at home but i doubt our house is efficient enough. Just one question, the bathrooms only get an extraction point, not a supply as well?
John Mackay Obviously with extract only it could create a bit of a vacuum in the bathroom so a small gap under the bathroom door is required just to allow some fresh air in.
@@TheBigSugs so what's replacing the warm air being extracted. Is that not the same as what Robin disliked about an extractor fan. Or am I missing something?
Air is drawn into the bathroom from under the bathroom door (whilst showering etc)
@@TheBigSugs so it's no different to having a normal extractor fan above the shower. It will just suck the warm moist air out of the room pulling air from under the door at the same time.
I believe so yes. There is a significant advantage though and that is that the additional warm air from the bathroom (caused from showering/having a bath) will be extracted & recovered by the MVHR system rather than just going straight to outdoors like a typical bathroom fan would do.
Hello,
Hope you well?
Thank you for another interesting and informative video.
Do you need any qualifications to install this system?
Did you require any form of training to install it?
Thank you
Ash
Hi Ashley, I went on a BPEC course and sat an exam that consisted of a multiple choice paper and a practical assessment, The course I did was at Blauberg UK in Leicester
How easy is it to retrofit this to an existing property and is it something you’d recommend? I like the idea of cutting down heating costs?
Great video 👍🏼
I think it would depend on whether you have joists like that and can access the ceiling space.
I think the technical term is a fkin nightmare. You can only really do this if you're doing a full refurb and I still don't think it's particularly easy even then. Solid joists everywhere!!
Robin, where did you buy Lindab equipment for the residential houses? I am looking everywhere, but no luck so far. Thanks a lot!
It came from Lindab
1300: looks like the bowels of Heathrow Airport
Does anybody know what the diameter of the semi flex ducting is? Looks quite big!
Beautiful system. Looks incredibly expensive
So how much does a system like that cost?
Is it possible to retro fit these in a Victorian terrace house. I have a 1900 terrace house and issues with damp in the kitchen and bathroom. It's a big house and a dehumidifier is struggling to keep up and costing a lot to run
All that house needs is some thermal mass and it would be lovely
Robin, what's the bell for at 11:12?? Intriguing... Cheers
Last orders!!! No when I bought the place this was the front door bell!! So we use it a coffee time!!! Thanks for watching
@@ukconstruction Ah, nice idea :)
I just wanted to say how much I thoroughly enjoyed the video too. Very informative and engaging! You're eye for detail and meticulous planning is great too... it's all the little details that most people skip over normally that turn a good build into a great build.
@@edwardholmes91 Thank you Edward
Great video. I'm adding EWI and re-windowing a late-60's house, starting to ponder if there will be enough passive ventilation when I'm done. Currently assuming trickle vents will do the job. I like th idea of MVHR, but maybe its a bit overkill unless you're going hardcore passive-haus?
is the main unit made by Lindab or Blauberg?? sure i saw it printed on it??
Can this be made in incorporate a humidistat?
