Thanks @markc also I seem to have reduced this video enough to upload! IMG_0492.mp4

I’ve taken some images of a random patch - went over quickly with bottom range vacuum, and it obviously has some paint and plaster spots I should get up. I tried rubbing with a crow bar and not much dust comes up, it seems pretty hard . Did video but don’t seem to be able to upload due to file size the glue you trowel on with a 6mm bead I think, which then compresses. I do need to triple check with a straight edge, I don’t have anything very long but will borrow sometching!

Thanks Mark! I was worried about the idea of water coming in and just sitting there against the wood of the door? Otherwise this sounds like a simple plan!

Thanks @markc @Bitpipe and @nod . So you’d recommend compound even if floor is flat and level and latency not an issue? partly reluctant because all our floor is in there waiting but I’ll get over it and move it if necessary!

Hi nod, the floor is pretty flat and level, would you use self levelling compound anyway? That seems like added expense . I see it could be a nicer job than sanding although I might mess it up!

This was installed by the window fitters, my instinct is to cut it back and potentially silicone along it on the inside. Anyone have experience? I’m about to lay engineered oak floor onto this slab after cleaning it

Hi everyone i’m about to lay my engineered oak floor to my concrete slab, sticking using sika 54 glue. a floor fitter I spoke to said we should sand the concrete slab to remove latency, at a very low grit. I haven’t found any other information about this online so can anyone share their experiences? The slab is pretty flat otherwise except for a few spots I can manage with a hand tool. If I don’t need to sand the slab I won’t as it doesn’t sound like a nice job and I would need to hire a floor sander Is it generally recommended to prime the concrete? Or is that only if it’s dusty? edit to add: the slab has a membrane, insulation and ufh pipes underneath it. It was a single pour thanks!

There are little pins that compress to keep window bars (not security ones, decorative ones to make it look like a 4 panel window) in place on the front of windows in a Scandinavian style chalet. Anyone know what they are called so we can google them to buy more!

Hi my mum has a wooden chalet that has wooden ceilings and she had to paint a fire proof product on the ceilings. It’s gone milky in some places and completely white in others as if it’s an actual paint. does anyone know how to reverse this whitening? Or would it be a sand back job. I think she has since realised she should have finished with a top coat that stops it going white but there we are.

So I went and investigated again today and realised the ASHP is on too (I hadnt noticed as it's so quiet), and some of the pipes into the tank are warm - the tank itself doesnt feel warm. I asked the plumber and he said it could be an anti freeze thing but the weather is quite a lot warmer than it has been (and we're in cornwall). He said he wasn't sure and to call Grant technical ?‍♀️

It's not RHI but I will give him a call tomorrow and see if he can pop by or advise!

If it's the immersion would it need to move water? It definitely sounds like water moving through/into the tank

Yeah definitely sounds like a 'doing something' noise. I just would be surprised if I happened to be there each time it was doing a legionairres cycle!

I'm not there right now but yesterday my energy account says the house used 1.16kwh, with nothing on except the standby of these displays for the heatng. That was between 6pm and midnight

It's been on whenever I've been there the last few days which would be a coincidence right? Ive got no idea though

The tank doesnt feel warm, and I dont understand why it would be if I have set the heating and hot water to always off. Unless theres some standby heating

Any idea why it's making this noise even when the hot water and heating are off?? I noticed when the hot water was off but heating was on, but heating should be coming direct fromASHP so I turned it off to see if it would stop and it hasnt? WhatsApp_Video_2021-01-12_at_15_13_20.mp4

Thank yoooou just wanted a good place to start!

Hi Peter, turning it one way makes the thing I am turning twist up and the other go down, any idea which is hotter or colder? The temp guage doesnt change immediately so I'm not sure!

OK I just tried turning it and nothing happened... I turned the room thermostat up too. Hope I turned it back to roughly the position it was in before! This is whats inside the little unit I pictured before

Thanks! but start lower, from 12 and increase like a degree every couple of days? Thats what I was told by the plumbers Yeah it's heating our downstairs to 17 degrees! Mad.

it's 125mm rockwool plus 40mm celotex in the extension and 55mm celotex in the barn (500mm granite walls) all one area, about 35 square metres But 2 big bifolds in the extension too The pipes are in the slab, one pour no screed, and we havent got the finished floor down yet, it will be engineered wood

also what flow temperature should I be aiming for eventually? and how slowly would you increase?

thanks! do I just turn it??

This one at the bottom? Then read the temperature at the top?
