Andehh

This all sounds like a storm in a teacup, it's not ideal.. But pissing your builder off in the final stretch is even worse Let him do more work, wait for next payment to be requested... Then link payment to site tidy up. Going to council or the police is a one way street to a loooot more stress.

It is really useful to keep an eye on what's going on, and adjusting temperatures and times I wouldn't be without it.

I've used the self adhesive plastic hooks/clips successfully. Ensure the surface is clean, and stick them below gutter for some protection from the elements.

Also very interested in this! For what it's worth, the Chinese generally make the best and cheapest batteries. They're several years ahead of the West, and even batteries made outside of China... Everything comes from them anyway.

Good luck mate, keep us updated! Well done for holding your ground.

We had 7 x electric roller blinds, incl 2 x 2.5m wide and 2.5m drop, for around £1800 fitted. Local family firm in the Midlands. Came back a few times to tweak and adjust to my OCD. About 2 years ago.

Will see how it is tomorrow, and give it a rub down to smooth it off. I think one side is a good few mm lower then the lip which I missed due to poor lighting. Only noticed it taking the damn photo, but 2 hours later I don't want to fiddle!

Thanks all, have finished the job. Forgot to pull in any mesh in, but for a small job I'll keep my fingers crossed. Not 100% happy with it, but it's one of those if I faff with it any more I risk making it worse... Only want it to last a year or so, as I'd like to tile the garage floor eventually... For now it's just trying to make it look tidy! We shall see.

Thanks! How do I achieve such a perfectly flat/smooth surface though? Or am I over thinking it? Do I need to do return after X hours etc for a final go over etc?

Yeah, that small semi circle area is sitting on insulation which the bastard screeders buried as they ran low in material. Builder missed it when he dig out and relaid the rest. I'll chisel it out and reconcrete, but want to achieve a very smooth flush surface!

Still like my idea of gallons and gallons of water proofing drowning the entire area, after a dry spell!! 😁

It was originally but builder dug it out, a miss communication with their team meant they didn't go far enough... So I need to just take out a bit extra. Rest has been down about 8 months without issue! You can see the sort of semi circle which is causing the problems!

Thanks all, sorry the water bit is just dripping from the car! Nod - are you able to link to the sort of thing you suggest? cheaper the better with it being such a small area!!!

When we had our garage floor done, the sub contracted bastards hid an insulation panel under the surface, likely as they ran out of material. Our builder came back 2 years later to rectify, and his team achieved a brilliant finish. The only issue is there is about 1sqft they missed, it's probably not worth me getting the builder out, so I'd like to cut this chunk out and reconcrete it myself. I've mixed plenty of concrete in my time, but achieving such a smooth finish I'm unsure of.... Pics attached, I filled a chunk with silicone just to stop water getting in. Other pic is what the builder achieved, and I painted over it. Any recommendations??

We had good renderers, but up or down lights are savage at showing up everything!!! Consider using then to light up plants or flower beds or the driveway instead IMO

Thanks John, with your estimations then, my system shouldn't be hitting 3 bar?

Unless you're going mad with insulation, I really don't think an ASHP makes sense in this sort of property. Why not replace gas, for gas?

Still following with interest! Good luck... These things can be a bastard for sure.

Go on then, what happened!? Post up some pics

For what it's worth.... I was in the same situation when I realised my wall mounted TV in the lounge, I'd forgotten to put Ducting in to the corner for my AV Amp, sky box etc... Realised just as the Plasterboarding started in the next room. I panicked out of work, was half way to screwfix when the site foreman raided the plumbers supplies and channeled out the wall for the pipe to be installed, and saved my day!

Wickes or equiv, will do all you need.... Small drainpipe (for shed guttering etc) , and or white sanitary drain pipes would work as Ducting as well. Use duct tape to seal the joints together,to avoid any liquid seeping in. https://www.wickes.co.uk/Products/Heating+Plumbing/Plumbing/Waste-Pipes+Fittings/Solvent-Weld-Pipes+Fittings/c/1000550 They open at 8ish, so grab, go and push fit, and you'll be having a cup of coffee by the time the screeders arrive!!

Several long screws pushed deep into insulation, either side of the Ducting, then any old wire tied over the top?

Damn!! They're so flippin' cheap. I'm not sure who I'd try and move to tbh!?

ASHP 12kw, with 230sqm of 16mm pipe, at 150mm spacing. Run temp is prob low 40s/high 30s? 18L expansion vessel. This pressure drop has been around since early on in the post installation phase. We had it for most of last winter, and maaay have had it during our first winter... We just had so many other bigger post move in focus points it wasn't a priority. So it may have been there originally, it may have gotten worse year in year?

Thanks, for the sake of £150 or whatever, I'll give it a go!
