Thank you. There is a spot on the ground level in the boot room, so not a problem. Was just wanting to locate the CU with the solar Inverter and velbus relay box on the first floor. Keep it all together. Common sense would say ground floor, I agree!

Hello, Can a consumer unit be installed on the first floor in a new build? Maybe an easy answer for someone with knowledge? Part M dictates accessibility of the unit i.e. height off the floor, but doesn't actually dictate ground floor? I know a plasterboard tent I used to rent had the CU under the stairs. Technically it was at the correct height - but was basically inaccessible even to me, no chance if you struggled with mobility. Thanks

Occasionally we got a clash of batten/cladding screws. Mostly we angled the cladding screw to get around the batten screw. Occasionally we had to remove the batten screw and move it 20mm one or other way.

Don't recall snapping any. stripped a hex head or two when I wasn't paying attention/pressure on the impact driver. I and another guy installed all of ours, we're the careful types, not the bang it up types.

I went with SS screws for what it's worth. Same layup, 60mm external insulation, 25x50 counter batten. 50x50 batten. Once you start getting custom cut larch, the price must be similar?

Man that is cheap. Did you use one? Thanks you for the suggestion. Never used Ali. Any idea on pressure loss? Another reason for DIY is because carbon filters for "plant growing" will never be discontinued, how would you get replacement filters in this case? I guess you could buy another whole unit if it is discontinued, bit of a faff tho.

How's this idea for a DIY inline carbon filter? Will be placed on the supply side of the MVHR. The reason to DIY is to double the carbon bed size at a slightly reduced cost when compared to Blauberg Clean box 150. The Blauberg Clean box 150 has carbon filter: 220 x 400 x 45 = 4,000,000 cubic mm DIY Rhino Pro Carbon Filter: Pi 150 x 300 x 50 = 7,000,000 cubic mm Lifespan: Rhino pro states 2 years at 600m3/h. So at 150m3/h (my case) expecting an 8 year life span. Part List: 150 duct. £15 / 3m 150 coupler. £3 Rhino Pro Carbon Filter: 150x300. £100 Custom 150 F to 355 M Reducer. £45 355 Duct. £90/3m Standard 355 to 150 Reducer. £20 Totals About £270 Blauberg £400

Thank you, supplier list: CVC systems BPC Anyone used: Paul heat recovery? Blauberg? 21 degrees?

Who did you use please?

The cheapest option is to cut you heating demand. This is done by cutting your heat loss from the building. This is primarily done with lots of insulation (very cheap to do) and triple glazed windows (very reasonable options exist). Solar orientation, building form and air tightness also have significant effects of heat loss. Is it simply money/month or do you value human comfort too? If you then follow the rabbit hole to its conclusion, you might consider building a certified PassivHaus.

Thank you. No not from my place, was an example i found of someone elses PH. We did exactly this, DPM on slab. Sole plate atop. Warranty instector was happy.

Appreciate that. And I agree. Finding it in non fencing sizes is not easy however. Also about 4x the cost. Pragmatism won out. UC2 used. End grain sealer on cut ends. DPM paint on top of the horizontal surfaces.

Literally having this issue now! I think counter battens should end early. So the drip tray can sit on the roof deck with a slight kick to the eaves board. The membrane sits on top of the tray. The vent sits on top of the membrane to allow air into the cavity behind the tiles, exciting at the ridge vents (and take moisture away from the building) The tiles then sit on top of the vent strips.
