Installing a ventilation system (MVHR) in an existing home
Video blog of a DIY installation of whole house mechanical ventilation with heat recovery (MVHR). The retrofit is in a flat in an existing victorian terrace house.

How much you charge to install
Did you have any concerns with locating the intake and exhaust vents so close to each other? I'm installing a similar system and everyone keeps advising against it due to air feedback loops. Any thoughts?
It isn't ideal, but you only need slightly further apart to reduce any cross contamination. There's only a very low flow out and lots of mixing externally so the risk is small. In this case it's first floor on an exposed street so quite a lot of air movement. If you're worried about it you can get combined intake and exhaust terminals that are designed to avoid mixing air flow.
Thank you.
"Danish warning" made me lol Great video thanks
Well done also looking for a compact system to retrofit with humidity sensors
How did you decide on the system and size it too?
What was your spend on this system in equipment? Do you have a shopping list as I am about to do a similar project
You are a champ!
I just started looking at these systems and came across your first video and I would like to thank you so much for sharing this short video covering all the main points of a MVHR and how you went about actually installing it into your flat. I would like to look at getting a similar system for my 1200 sqft 2 story home that was built in the late 1990's. The question that came to my mind is what type of heating system did you have in the flat? And did it improve the efficiency of your heating system after installation i.e needed less kWh. I currently have a radiator based central heating system and was not sure if this system might be more suited for electrical heaters.
hey please do a lot of new video! I love to watch your process
amazing work!
Cool. Another illegally installed ventilation system that will fail permit inspection and have to be removed before the house can be sold. This is idiotic.
The system was commissioned by a BPEC engineer, signed off for UK building regulations and the flat has since been sold.
Thanks for this - very interesting!
Great video! Just wondering how your controls work - do you turn it on/ off manually? or is there some kind of occupancy sensor? I'm looking to install MVHR in a music studio where occupancy is less consistent than in a home, so I want to avoid having the fan running 24/7. Similarly with the heat recovery, are there any automated controls for bypassing that in the sunmer? Or would you do that manually?
Hello Stevie, it's a manual controller with 4 speed settings. I leave it running 24/7 at one speed, a good strategy for most homes, but you could set a time program or there's a humidity sensor option for different speeds. The summer bypass is automatic based on internal and external temperature. For your application I'd leave it running all the time at a very low speed, then turn it up manually when you use the space. Some manufacturers do an app now (of course) so that might be useful to you. Most of the time it's a bit overkill.
Delighted to see this kind of product in action in the UK! We are sooo late in terms of air tightness and whole house ventilation!
does the ducting have to be inside the thermal envelope? Does the unit have to be inside the thermal envelope of the buidling?
Thanks Will! This inspired me to DIY install an MVHR system in my house. I managed to do 75% of it myself with the remainder done with some help from my plumber. I got ducts to every room in the house with only needing 1 section of boxing out in the corner of a room. Delighted with it and I’m already enjoying the benefits of the summer bypass as the weather starts warming up! Thanks again for the inspiration :)
What brand and where did you buy please? Looking for recommendations for a Victorian terrace
I really like this project but my lease won't allow whole in the walls 😢
How noisy is this system?
Does this heat the home too?
What to do if you don’t have a suspended ceiling?
Find some neat areas to box in ducts, an area where you can drop the ceiling like a corridor, or use the loft (under insulation). The solution needs to match the property, the only rule is that there's always a solution!
Thanks for recording your install and sharing. This gives the DIYer an insight to process of retro fitting these 👍🏼👍🏼👍🏼👍🏼
Great stuff. Really helpful vid
Outstanding work. I'm just about to install a single room heat recovery Ventilator but your job is a work of art. Well done 👏
Maybe this way will work for you: ruclips.net/video/9MXjsS6J7Cc/видео.html
@@ajavrick thanks for the video. That's quite a sizeable unit! I've completed mine now. It runs on a constant trickle feed and turns on via a humidistat. Seems to work well so far. Thanks again for sharing your information 😀
Any idea on running costs?
Thank you for sharing Do you have any info on running costs? And is your house warmer?
About £40/year, but saving more than that on heating so will be net gain. Not much on my flat as I don't have great airtightness, but about 15x for newer build.
Not warmer by default, but warmer for the same air quality as I don't have to open windows in winter.
@@wilfredsouth2482 my house is old like your flat
Really cool! How’s it working out now after 2 years?
Great work nice video great technical skills neat finish well done
Now we just need to fit this to EVERY home. Nice work. Please put links in description
Could you share some installation costs? How much for the unit? How much for piping materials?
great job, man
Great video! Thanks for sharing, I just noticed that you intake and exhaust are too close to each other!
fuckin hell would have been easier to plug a dehumidifier in christ
It's not just water vapour that lingers in a house. Carbon dioxide builds up really quickly too. I'm planning to install a system, but my motivation is the fact that the CO2 level in my work-from-home office rises to 3800ppm after working in there for just three hours, and that's enough to stop one thinking clearly and give one a headache. And the condensation on the windows too.
Excellent video, so Wilfred that is your new business! if not it should be, you have a Knack for teaching.
Boss Video Wilfred.
What type of Nilan heat recovery box is this? After watching your video I may also make a false ceiling.
Great video. Thanks for the walk through.
Really nicely done - thanks for sharing your experience.
"They look great" ... I see what you did there. 😆
Great! Thanks for sharing. Is MVHR possible to conduct pipe across different floors in property? I plan to install MVHR in my garage on the ground floor. Is it possible to conduct pipes to bathroom and bedroom on third floor where I think were the most damped in home? Or should I install the MVHR on the loft, thanks for your advice
Great video. Very helpful. You mentioned that you will need someone to measure and commission the unit after installation. Can you recommend someone? Thanks in advance!
My auntie Hussa has this MHVR diffuser vents in her kitchen!
Can't hear a bloody thing!
Thanks for the video, very useful for me. Cheers! May I ask where did you buy this MVHR system? Thanks
I need a service to my unit any recommendation
Open job Wil, some bloody tuff obstacles to overcome there i think you could do that as a full time installer.
Hello, great video. Can you tell me where I can get a design specification done? Thanks
very good I need to install at home
Lovely job, what a pro. The trick with the magnet was the best tip!
I'd have never thought of that trick. Brilliant.
Awesome video! Did you source all the kits yourself? I'm based in South London, struggling to find someone to design and supply the whole system. Any recommendations? Thanks
Yes I sourced it direct from the manufacturers. Nilan and Lindab. You also could try Enhabit, Green Building Store, Passivhaus Store, or Greenwood for a design and supply service.
