I have just fitted similar myself, and yes mine protrude far more. I hade to cut away the plasterboard when I fitted the valves to get them far enough forward, so the only thing that reduced how much they protrude was the tiles. As I did mine myself I was able to mock everything up before finalising the depth of the valves. so yes unfortunately you are going to have to re position the valves much further forward, so if you can get to the back of them that’s probably easier than removing the tiles.

I agree for £40 it’s worth a try as it seems the most likely culprit

Oh right mine didn’t say that, it has a set pressure. yeah doesn’t explain where it going, you’d think the diaphragm was leaking but you said no water from the valve ?

The label says 3 bar so I’d do it to that.

The only metal you should have would be copper, which also will not rust, but yes it’s more likely to have condensation Not sure what you mean by metal-y or plastic-y ?

Have you represurised it, I think those ones need quite a bit of pressure, 3 bar as on the lable If it’s not pressurised the expansion of the hot water will cause the overflow then the working pressure drops and you start again

They won’t rust as they won’t be steel the rising main is mostly likely blue and is mdpe which won’t corrode or rust I don’t get any condensation on either of my rising main pipes or any of the cold pipes under the sinks ?

With the Veismann 151 the 16L buffer is located in the indoor unit with the DHW cylinder. don’t know if there’s another small one in the outdoor unit

I put truss clips on as building control wanted them

Yes exactly like that Before the concrete was poured I had the wall plates sitting on the scaffold with m12 rods pre drilled through the timber and made a float 47mm tall so I could set the height of the wet concrete, then just pushed the m12 rods with nuts into the concrete. After the trusses were fitted and nailed to the wall plate I cut away a little of the inner eps to fit the truss clips

Have you tested the 4G speed ? I have recently completed a 4G set up and consistently get more than 120 Mbps I got an unlimited data sim on EE for £30 a month

I didn’t have bird mouths, I had the trusses cut to sit on top of the wall plate, which fixed with bolts imbedded into the concrete, the wall plates were flush with the top of the ICF block, I then fitted the rafter overhangs after.

Mines around £1100 m2 ICF chalet bungalow, Alu clad timber windows, German kitchen. but did a lot of the work myself. Will be a bit more once landscaping and driveway done

Dot and dab is fine if done correctly with a continuous bead of adhesive all around the perimeter of each board, then wet plaster skim

Yeah they are bloody expensive, not up to a Stiebel Eltron though they are really expensive. I do also think the Veismann indoor unit is very neat compared to most separate DHW tanks and associated gubbins, it doesn’t take up much more if any space than a traditional ( non slimline ) tank

Well for £1800 fully installed with extended warranty I’m not complaining. You certainly could not purchase and install a better system yourself at that price,

Well it’s installed exactly as Veismann recommend. With no Glycol or antifreeze valves

The buffer is only 16L it’s not your traditional extra volume buffer which I agree in a properly designed system with sufficient volume are not needed. And it does not need an additional pump. I think Veismann know what they doing

The Veismann unit doesn’t have any surplus crap. the only valve is for Heating or DHW, the buffer is there to assist defrost, so no glycol or antifreeze valves needed. I run mine open loop UFH so very simple. I did my research before buying, I was going to buy and install myself, but for £1800 for a top end system with long warranty why would I do it myself ? I think others get caught thinking they’ll save money doing self install and ignoring the bus grant.

Why not ? It’s very neat and efficient compared to having it all separately plumbed in. Especially if you had limited space

No the indoor unit is the DHW cylinder and all the associated pumps and valves, makes it really quick and easy to fit, the outdoor unit is the heat pump

I fitted windows first then the render

A plumber local to me near Norwich mines a 4KW but they go up to 16kw I believe no idea on service cost.

Pro Clima Aerosana Visconn from https://www.ecologicalbuildingsystems.com/products/airtight-windtight-systems/membrane

They retail well north of 5k nearer or over 8k Fortunately the plumber charged me trade price on the unit but made £3k on the install which only took 4 days
