You’re god-damned right there should be!!! Theres zero stopping the frames from moving. Open the window and push it to see for yourself.

I can see a concrete screw, but no packers

Quite normal for a window company to underside, but what have they done for fixings? Also, often the head of the opening used the window millions and frames for structural support, so I wonder if the opening is suitable to take this simple swap. Worth checking, particularly with curved bays. One way these are otherwise supported is if the floor joists from upstairs project outboard to take the weight of the above elevation/bay. Can you take a pic showing the front and head of the opening? To seal up, if they’ve fixed them robustly, you would want a continuous bead of Illbruck 330 foam Link (NOT regular builders foam) which will reduce noise and draft to an acceptable level, and then uPVC ‘makeup’ usually gets set in place to make things pretty.

UFH flow and return switched intentionally
Nickfromwales replied to Rubics's topic in Underfloor Heating
Yup, agreed, but the isolations are probably moot as there is just so little system volume above the manifold rails to not have to worry about 'draining the whole system down'. -
UFH flow and return switched intentionally
Nickfromwales replied to Rubics's topic in Underfloor Heating
The combi should have an integral bypass, but that should be a failsafe only. WRT losing the UFH manifold pump and blending valve, I’m not so sure that’s a good idea as then you are at the mercy of the flow temp from the boiler. How long has the heating been on for, and do the floors feel warm/hot with flow going in at 70°C?? The hottest I’ve set these to in adverse conditions is about 45°C to get a floor surface temp of 24/25°C, and a room temp of 21°C. At 70° it should be like Barbados in there. How is this performing currently? -

That's the flow out of the pump. -
UFH flow and return switched intentionally

Hi. For one, the flow gauges iirc will only register flow if the water is going into that rail, as the water pushes into the pipe loops there is a slider that gets drawn into the current and that pulls down the flow register in the gauge. As per your pic, the pump is running but the gauges aren't appearing to be doing anything? The other thing, is that pumps are suppose to be mounted vertically, but that's just old school mentality from 30+ years of plumbing (I don't mount pumps any other way) so air can rise upwards with flow vs against it. Also, as the boiler is only servicing UFH via a mixing valve, there should be a bypass, other than the one ion the boiler, so when there is pump overrun (the boiler pump is pumping faster than the UFH is consuming that flow/pressure) it can cycle back on itself. That promotes longevity of the boiler, and shouldn't be dismissed as 'unnecessary'. Finally, does that gauge show 70oC flow temp?!? Who commissioned this and what is the target/design flow temp that's supposed to be going into the floors? -
Does the flue exit on that wall or at 90o to it? If the same wall, is it sealed up properly so no rainwater can penetrate and get into the mortar joints? Is this evident when it rains/immediately after, or 24/7?

Yup, they would have known about the paternity stuff roughly 9 months in advance...?

+1. Maybe get a rudimentary bill of quantities done, to show the lender that you have your side in check eg that you know the actual costs required to get to a completion certificate. All you need here is the BCO’s sign off, architects are being dicks.

They’ve used JG Speedfit, and as always there are no circlips installed behind the collars….. This is why I only use Hep2O (Wavin Hepworth) push fit in every permanent installation I do, and have done so for the last decade. JG has the ingenious flaw of slowly undoing itself over time, and this will be 20X more of a concern with heating as it’s going hot-cool-hot-cool so will expand and contract for the rest of its serviceable life. Get the circlips (collets) LINK fitted before the boards go back down and sleep soundly. Copper is king, always will be, but modern push fit is perfectly acceptable when installed CORRECTLY.

Wall tiles out of level / not flat surface
Nickfromwales replied to MortarThePoint's topic in Wall Tiles & Tiling
Yikes. I’ve dot & dabbed tiles more times than I can remember, but always with cementitious adhesive and never without having completely buttered both the reverse of the tile and the wall. I’ve tiled for over 3 decades, never a callback / other issue, not with grout and not in wet rooms or wet / splash areas, so the principal is fine I assure you, just this guy is too comfortable riding the luck train. Is that ready mixed adhesive from a tub? If you’ve heard sounds then that sounds like excess adhesive having the moisture sucked out of it from the porosity of the tile and the bone dry plasterboard. That usually results in the adhesive shrinking back and tiles drying in place differently than where they were ‘laid’, often resulting in kickers and uneven finish. Here the walls simply don’t look bad enough to have any reason not to have done bed & butter, plus there’s no sign of him ‘squishing’ the adhesive into the tile and board by moving them around as they’re set into place. -
Some stopcocks have a washer that falls to the closed position in the absence of ‘flow’, but that’s a random addition to the possibles for the process of elimination here tbh. The problem with noises in a plumbing system is they can be produced somewhere away from where you think you hear them. Swap that back to a gate valve, as that’s a cheap possible win. Then try again!

Wall tiles out of level / not flat surface
Nickfromwales replied to MortarThePoint's topic in Wall Tiles & Tiling
Yup. Nice isn’t good enough, needs to have quality or what’s the point. Make sure you have spares of the batch of tiles above, then ask your new tiler to cherry pick the few bad ones and re-set new tiles in to reduce the issue. Does just seem a bit of complacency had set in from the pics, as just the odd one vs a whole shite lay….. shame as you say but needs doing properly, simples. -
Where is the F&E teed in? Possibly look at relocating that.
-
Heat pump yes, but the demand will have to be known, and the temps won't be much or any better unless it's a high-temp split which will give a decent CoP at 60+oC. That leaves you heavily reliant on burning wood to keep the whole house 'warm' if the rest just adds background heat, but in bedrooms and other spaces away from the WBS I expect the rads are actually doing much more than you may first realise. Turn them off over winter and test this theory afaic, and then maybe readdress this in the new year when the UK warms back up a little.
-
Just the worst possible one, in honesty. Not unless it's massive. The losses will outweigh the gains I'm afraid, as, for one, the storage type and useful energy capture to then run these high temp emitters will be of negligible practical benefit in actuality, plus the accumulative losses and poor responsiveness will further add to the negative maths. The last TS I installed for space heating to rads was 2600L, and took up a 1/3 of a garage (for comparison). That stored at 85oC btw. Driving this into a slab with UFH would work, but for rads I'm afraid it's a battle on a good day to suggest this is a 'good idea', sorry!
-
Just a 'not great' solution to be honest, the immersions into a TS, so these are my thoughts.
-
This may require a second G3 sign off, as you're then sealing up a pressurised cylinder which could go "bang" in the perfect storm. The thermal store type needs to be considered and whether or not it has a T&PRV relief valve or not, but a decent installer can talk you through this for feasibility before committing. It's just the thought of your heating costs via indirect immersions and then the losses of the F&E setup that make me think there's a better way perhaps. It may require a new TS in the worst case, but if this is your heating solution for life, I'd even consider an electric inline boiler and do away with the TS altogether as that is a very convoluted and inefficient way of changing electricity into heat tbh.
-
As this is now an expensive way to heat the home, I'd defo consider converting to sealed and pressurised, and do away with the F&E arrangement for good. Then there's also no way for air to get in. https://www.bes.co.uk/intafil-plus-24ltr-heating-vessel-and-sealed-system-kit-20246/ for example

Replacing first level joists in tight area
Nickfromwales replied to Paulie80's topic in Floor Structures
Hi. I've recently done a 16th century cottage bathroom and the floor was like a piano keyboard, as you walked the floor deflected downward at each joist. Then ensued the biggest pig of a job you could wish for, getting it solid and level enough to be converted into a quality ensuite with bath and wetroom shower area. I sister'd the biggest timbers I could get in, but on both sides where it needed it, glued and screwed to death with zero nails used ANYWHERE!! You can park a car up there now. Do all the strengthening work, then get an electrician to drill the joists to re-route the cables, and then lay 22mm P5 deck, again glued and screwed, and you'll be fine. It's a LOT of work to do these properly (retrospectively) and I did have to re-do some of the plumbing tbh, but you get out of things whatever effort you put in. Good luck! -
Oddly the blade appears to be installed in that saw backwards….may be worth asking why if considering buying.

If you’re doing skirting and architraves all day every day then crucial, but most have it at entry level anyways. Dual bevel is nice if you can spare the few extra £10’s.
