I fixed it. You can only edit posts for 30 mins after paying. After that, you can report your own post and ask the mods to edit.

Yes, we've required a £100 deposit (roughly the cost of the unit, I believe) for two or three years now. Basedon feedback from users, I've been thinking about increasing the hire price a little to cover the cost of getting/keeping it calibrated.

These documents are from the anemometer hire thread that you can't see yet due to not having enough posts: NHBC MVHR Commissioning.pdf Passivhaus MVHR Commissioning Requirements V121.pdf domestic_ventilation_compliance_guide_2010_edition.pdf Vent_Calcs(1).xls MVHR_Sizing(1).xlsx That thread also includes the following additional comments that might be of interest: To calculate the flow from speed, multiply the m/s by the area of the anemometer vane opening and then 3600 to m3/hr To calculate the area of the anemometer vane opening use the formula A = π r2, r being 1/2 of the diameter. There are calculators online where you can enter the radius or diameter and it does the calculation for you. Alternatively, spend a few minutes working out a small range of m3/hr values using the vane opening measurement so you have a ready reckoner to check. As well as a cone, you ideally need a flow straightening section, although this is less important with a vane-type anemometer. With a vane type unit, you ideally need to ensure that most of the airflow goes through the vanes, as long as that doesn't cause too much of an obstruction. For domestic scale measurement a 100mm diameter measurement section is usually OK - it's a reasonable compromise between getting the flow velocity up to a measurable level whilst not impeding the flow enough to significantly change it. Here's a photo of the unit I made up with a 100mm length of duct: This shows the Testo being used, and the reading is in m/s. To convert this to l/s, then take the internal cross sectional area of the measurement point (in this case it happens to be 0.007354m², allowing for the bit blocked by the sensor probe), and use this formula: Flow rate (l/s) = flow velocity (m/s) x 0.007354m² x 1000

It's working - see the rest of the sentence with the link: Having lost two hired anemometers to members who disappeared, we won't hire out the remaining one without at least some evidence of engagement on BuildHub.

Unfortunately, if they aren't selling, the price is probably too high. FB marketplace is often a good way of getting a sale if you price well.

Drawers all the way. The one issue is that they massively increase costs compared to cupboards.

We did just this with a tired old 1950s bungalow in 2015. It's almost certainly the right decision - far fewer compromises on both design and construction, plus you derisk the job considerably. You'll be amazed how quickly you pick things up. Good luck!

Lovely looking project. How awesome to have had so much involvement, too!

Ah yes, the MVHR sub-forum. I should never do anything on the mobile.

Welcome! Post any questions or concerns over in the ASHP sub-forum and I'm sure you'll get the help you need.

Welcome to BuildHub. I've moved your question to the ASHP sub-forum where it's more likely to receive more attention. If you want specific help, you need to be specific. No-one knows whether they have the same problem as you if you don't tell us what it is!

Fundamentally, planning departments are reactive. We'd nearly finished our build before it sunk in that the planning department has no practical interaction with the build after planning permission has been granted, unless someone complains. I can't imagine anyone complaining about removal of protective fencing, and even if they did, what could the council do? The general cure for a breach is to correct it (e.g., "You need to plant and maintain a hedge along boundary A"), but since the protective fencing has been removed, there's no longer any way to correct the breach. They're hardly going to make you reinstate it so you can ask them to approve its removal! We had a similar condition on the extensive fencing protecting the trees around our house. I only realised that when re-reading our planning approval about three years after we took the fencing down! We were also supposed to have regular inspections by the arboriculturalist, but decided against it. We felt the worst that could happen had they found out was that they would require us to start doing it. We figured we might have saved the cost of several visits by then.

Good luck!

If I understand what you're trying to do: in the new post, place the cursor where you want to add a quote, then go to the post of interest and click the "Quote" button. If you have to go to a different page in the thread to find the post you want to quote, it might place the quote at the end of your current post, but you can just drag and drop it - see the top left corner of the quoted block while hovering over it - to where you want it in the new post (unless you're on a mobile, in which I case I can't help you because I've never managed to this working on my phone!)

Welcome! Best bet for searching is Google your query and add the word "buildhub".
