Ambaz79 Posted September 11, 2023 Share Posted September 11, 2023 Hello I have the MVHR all installed and now just need to set the flow rate for each room. I'm sure I have seen there is a Anemomitor available to borrow if I leave a deposit. Please can someone point me on how to get this organised?

Bonner Posted September 11, 2023 Share Posted September 11, 2023 That reminds me … @jack, is the anemometer still available? Link to comment Share on other sites More sharing options...

Yes, follow the link @Bonner posted above and I'll add you to the list. It's been stuck with someone for a while but I've sent a reminder this morning.

Thanks! Hi Vas (and welcome to BuildhHub). The link becomes available after you have a certain number of posts (10, I think?) and it isn't possible to access it before then. There's short queue of people for the tester in front of you, so it'll probably be a few weeks from now before it's available. If you work on getting the required number of posts in the meantime, I'll add your name to the queue now so you keep your place. Link to comment Share on other sites More sharing options...
Vas Posted September 17, 2023 Share Posted September 17, 2023 Hi @jack, Could you please add me to the list and I will try to be more active on the forum! Thank you! 1 Link to comment Share on other sites More sharing options...
Hastings Posted October 12, 2023 Share Posted October 12, 2023 Be aware that a UKAS calibration certificate (less than 12 months old) might be asked for if you are being inspected by building control. Link to comment Share on other sites More sharing options...

Definitely worth checking with your BCO before relying on this unit, although I haven't heard of any of the nearly 30 people who've used our uncalibrated unit having had an issue with building control.

joe90 Posted March 19 Share Posted March 19 My BCO didnt even ask for any figures, but yes best to check. Link to comment Share on other sites More sharing options...
Hastings Posted March 19 Share Posted March 19 (edited) The requirement for a recent calibration certificate is in the 'Domestic Ventilation Compliance Guide' along with a commissioning procedure checklist. I based my own commissioning report on this in because I couldn't risk the additional cost implications of a rejection. I will never know if the BCO ever looked at my DIY report (see attachment). The hire of the calibrated (and on an approved list of models) anemometer was £150 including shipping both ways, still leaving me a saving of about £650 over the best quote I could get for having someone else do it for me.

RafM Posted March 20 Share Posted March 20 I'm part way through installing an MVHR system. I've seen pretty cheap anemometers for sale and was going to use one to set everything up. Are they not up to the job? (I'm not having a BC inspection) Link to comment Share on other sites More sharing options...
Coanda Posted March 20 Share Posted March 20 I set my DIY system up with one I got on a well known online auction site. How accurate does it need to be? Link to comment Share on other sites More sharing options...

My BCO would not budge and had to rent a calibrated unit from Sun Rentals. The BCO then accepted my own report but this was an unusual case compared to most on the forum. 1 Link to comment Share on other sites More sharing options...

I did the measurements just to satisfy myself that the as-installed settings were about right. Link to comment Share on other sites More sharing options...
