The cost in building valleys is in the joinery rather than the leadwork. A 6m roll of 450mm will set you back about £100 all in, the valley rafters and associated timber boards etc will be your cost. Are you planning a cut roof or a truss roof..? And are you planning on built in solar panels..?

Visio uses a slightly different method - they aren’t stored as icons and the libraries are a custom data type as I’ve tried to export them and transfer to LibreCAD previously using a couple of different tools. I’ve got the stencil files somewhere.
-
Lucidchart is the Visio for Mac. There are symbol libraries available for that too but not sure what ones. @vfrdave I will dig out the file names later so you can search for them or I can send them over.
-
Visio has a massive library of M&E /HVAC symbol libraries if you know where they are - they are installed but not visible usually. This is my ASHP done in Visio

But the soffit is plastic or coated aluminium ..? Render will wipe off. Don't create a problem for yourself, get the trades to do it properly ..!

Warranty inspection woes.
PeterW commented on curlewhouse's blog entry in Sips and stones may break my bones...
Don’t forget that private companies bid for your work in effect so there is no harm in providing a draft set of sample plans and asking them if there is anything untoward that they aren’t used to. I can recommend a company in the Midlands that I’ve used - helpful and very keen when he saw it was a self build and saw the quality of the build work so far. -
Depends what you’re trying to stop getting onto the soffit...? If it’s render, the best way is use nothing and get the render team to keep it clean and wiped off as it makes them clean as they go... otherwise you can end up with tape stuck behind the render and the only way off is a knife ..!

Design of drainage in to be built over mains manhole
PeterW replied to Jml's topic in Waste & Sewerage
I’d put a pair of 45 or Y branches into the existing manhole, one each side. New stack into one - that needs to be your venting compromise unless Thames agree someone else is venting the sewer as you could fit an AAV. Second branch to the kitchen, carry on up past it into a rodding eye if you can and roberts your aunties husband .... -
Don’t these also need the i-box too so that’s another €50 on the price.

Isn’t the Hansgrohe one you can programme the time for the bath filler..?? So you can start it and wander off and it’s filled to the correct level when you get back ..? Think I am going the Mira route ...
-
26l/min is an average bath in 5-6 mins. Not unreasonable for a perfect temperature bath ..?
-
Thats a standard property of carbon film resistance heating - the warmer it gets the less it conducts. It doesn’t care if the heat is from the electrical resistance or from an external heat source, it will self regulate. It’s the same technology that has been used in trace heating tape for years.

Should..... but some of the Baxi’s used to have a bleed screw as the top tapping was just below the top edge ...
-
Ok ... do all the rads have bleed screws that work ..? does the boiler have a bleed screw on the top of it ..? If so, then close the valves to all the rads and open the fill valve for the header tank and let the boiler and system fill up. Bleed the back boiler if you can at this point so you know that’s full. Then one at a time, open a radiator valve and then open the bleed screw to let the air out. Work from closest to the boiler and ground up so lowest to highest. When you have done them all, turn the pump up to max and turn the room stat up and let the system circulate and go round again and drain the air out. Finally... light the fire and it should start to heat everything

Impey trays tend to need a good push to make the drains click properly. Have you pushed it down hard so it clicks ...??
-
So are you not looking to polish the floor..? Just a pure powerfloated finish ..? It will need protecting whilst you’re working as otherwise plaster, adhesive etc will get into it. Once you’ve done then it will have to be sealed otherwise it will continually scuff dust up so that’s an additional expense. This will need to be maintained too. If you are considering polished concrete where the aggregate is exposed by grinding then you are talking about a fairly substantial cost on top of the laying. The concrete pour also needs to be done carefully and not over worked and has to be as flat as possible as you can’t fill troughs you have to grind down. I’m pretty sure someone on here had polished concrete and the costs are around £60-70sqm, which is far from being a budget item ..!

Not worth it IMO as they are so cheap to buy. Only time I’ve made something rather than used biscuits is when I joined two long sections of work surface and used a thin strip of ply down the whole length.
-
It was Visonic - not Texecom - I had an issue with..! Sorry ..! Just checked the codes on my phone ....
-
Texecom stuff is good but they supposedly don’t supply to end users and getting engineer codes is down to searching the interweb from experience.

https://www.mouser.co.uk/ProductDetail/MikroElektronika/MIKROE-1630/?qs=QhAb4EtQfbUP1yCGjXhiRA%3D%3D I’m sure I’ve seen one of these as a home brew air quality sensor - just looking for the link.
-
So.... I would ditch the EPS and go 150mm of PIR which gives you 0.1 on the uValue. Then it’s 100mm of concrete on top - Agila or similar flowing / self compacting and that gives you 35mm chairs for the mesh, 16mm pipes and 50mm over. Quick and cheap.
-
Is this sand & cement screed over insulation over a concrete oversite or slab..? whats the floor make up as that will affect the thickness needed
-
Looking into this they are taking the components as standalone, not part of a system. So in that instance if you have UFH mat as part of a larger "system" then the control element comes into the equation but their efficiency calculator doesn't take this into consideration. Not that this has affected the 20,000 or so eBay products available currently....
-
Oh I don’t ...!! As someone who’s been involved in taking regulations into legislation, I’ve seen more than my fair share of these not just from the EU..! I think its a rather amusing human trait that wherever there is a test or a standard that needs human “involvement” then the human element will try and bend the rules to make things pass ....!!

There is a method of brick slip that uses a preformed and skinned EPS backing board that is about 25mm thick. It has tracks built into it that space the slips vertically, and then allow the slip placement in the grooves. I spoke to the supplier who said it was used for retrofit solutions but could be used on ICF. I’ll need to dig the details out.
