Hi all. Running my ductwork and installing plenums currently. I have a plenum that due to lights getting in the way is currently tucked in a corner. It will eventually have a Ergovent diffuser attached, as shown in the link. https://www.ventilationland.co.uk/en_GB/p/ergovent-frameless-ventilation-valve-round-125-mm/18706/ I currently feel it is too close to the corner of the room at 200mm from the centre to each wall. But I am a bit stuck for space due to lights/ joists etc. Any views? Cheers Dave

Thanks 👍

What heat battery did you use?

Thanks for pointing me towards the Cavius smoke detectors. They are just the type of thing I have been looking for.

They look good. I will have a look at that website. I was looking at ones like the round diffuser but they were over £150. £80 seems more acceptable. I totally agree about trying to keep the clutter off the ceiling. If only I could fine smoke alarms that look nice.😂

I was looking at the Zehnder ComfoValve Luna S125 for the supply. The recommended minimum distance from corners is 350mm in there documentation. They have what looks like a foam segment that you put in to slow the flow pointing toward the corner. This is where the 350mm came from. I quite like the look of these valves and they seem affordable. However what I would like is a plaster in type diffuser so I don't have anything protruding down from the ceiling but I cant seem to find any that don’t cost stupid money. Any recommendations?

Yes it is one large kitchen diner. The extract over the island is close to where the hob is. I could ditch this and just have one extract.

Yes I would like to remove the address, silly mistake on my part. How do I edit my original post? Yes I am trying to make the property as airtight as I can. It is a 1930's house so there has / is a lot of sealing done or to be done.

Hi all. I am in the midst of designing my MVHR system for my house I am renovating. I am happy with he design on the whole but I have one room that I am not sure about the vent placement, indeed even if I should have supply vent in that room at all. I have attached my proposed layout / vent placements for the first and ground floor. Any comments are more than welcome. I have also attached a ground floor layout marked up with a 3.5m distance between a supply and extract vent. My question is this a great enough distance to prevent short circuiting? Also do I even really need this vent? I added it to help bring down the air velocity in the main air supply vent on the ground floor. I realise the ducting takes a convoluted route on the ground floor. This is because I am dropping the ceiling level every where on the ground floor by around 100mm to accommodate services except in the hallway. All vents located near corners are 350mm away from walls. Also would you normally put the vent in the bathroom above the bath / shower area? Thanks for any advice.
