Yup.... ....and yup.

Normally ass-ociated with a pasty-rich diet. 💨 🤢

Spraying 30mm of foam will defo help keep the bath warmer for a bit longer, and leave access for plumbing ( with some strategic foaming / cutting out ). Certainly won’t hurt that’s for sure!!

Yup. Problem swerved is the cheapest option, just need to be sure with a heat demand over 3 manifolds, that it is manageable / practicable. A lot of programming can resolve it. Quite odd that it’s been set up to overlap tbh!!

The 3x 2-port ( UFH ) valves go downstream of the W-plan 3-port DIVERTER valve on the heating out port. Cylinder to HW port. Problem solved. Depending upon number of occupants / build type / DHW consumption, this may need a decent sized buffer to maintain heat to the house whilst DHW recovers fully.

Needs to be set up as W-plan aka DHW priority not S or Y plan

Cracking bit of kit for the money, I’m very impressed with the ones I’ve installed to date. I’d install this plus a HP UVC now, as you’ll defo regret it in 5-10 years eg after it’s too late to recover the spent ( ever rising in price ) electricity. I used to be a fan of an all electric ( non-HP ) PH, but after seeing how ( exceptionally ) well these units perform and the unarguable CoP values…..not any more. No ma’am. Add slab cooling as a residual ( free ) bonus, and it’s a zero brainer. Introduce an EV and attempt to charge that during daytime pockets of ‘excess’, and then you’ll be saying a very long “goodbye” to every ounce of excess previously earmarked for “other diversion”. That means either the majority of your DHW comes from the grid, or, you opt to charge the EV to near full overnight, and only use it to capture any excess during the day by tethering routinely and filling the remaining ‘gap’ you’ve purposefully left. Unless retired that’s a little impractical in honesty. PV into a HP as a multiplier is the logical path, giving up to 3x the revenue per kWp of roof space. Turns a 4kWp array into a 12kWp equivalent. Couple this with; both heating an oversized UVC and charging the slab from cheap rate EV tariff, and you’ll be sub 5p/kW for a huge chuck of the winter heating and DHW, where PV output will diminish to less than 25% of the net micro-generation. Measure twice, cut once 😉

100%. A major problem occurs when the ‘agents’ look to the client, some who’s balls greatly exceed the size of their brain, and follow their lead. Only possible if you understand the disciplines required to arrive at each milestone, but much more manageable even if being done with the minimum level of professional support.

Apologies for my straight-talking nature, but it’s far better to see a big mountain of 💩 coming, vs being stuck up to your neck in it with the ‘exit routes’ all bolted shut. Best thing you can do now, is formally request a list of ALL of the contractual omissions from the frame company, broken down into an itemised list. Then look at what it will cost / what you could undertake and reassess the situation. Best for a reality check and regroup.

Positivity is a beautiful thing, but utterly wasted when folk have to start asking “so, who was SUPPOSED to be responsible for that?” when it turns out nobody is, ever was, and nobody bothered to mention it ( until after they were deposit paid and locked into a contract riddled with ‘small-print’ )…… MBC TF ( zero affiliation btw ) take full responsibility for this slab / frame coordination, plus it means the frame goes into production when you pay your deposit ( as with any turnkey slab + structure supplier ) thus avoiding huge delays, eg waiting for the slab to be done before the chosen TF company will come and measure it and then go into production. Typically, the majority of things which are laborious, require huge input, and time, are often in the list of items referred to as ‘by other’. Fine by me, as it keeps me exceptionally busy all year round. 👌.

British Gas hired Bristol crown court to reenact this exact scenario as an example to what would / could go wrong. My mate was part of that theatre, and trust me, when HSE turned up to my other builder mates site ( after a labourer fell two floors and fractured his skull / multiple near fatal injuries ) that’s the first thing they hunted for. He was dragged over the coals, fined massively, and had to undertake strict site HSE training etc and more. Plus he had mysterious visits to his registered sites for some time after. What is written seems to be contradictory to the HSE’s own actions after such an event.

Yup. A lot of mess and confusion. I walked away in the end.

Having a few local PIR's will allow the lights to come on as you walk towards, and stay illuminated for x mins after you've walked onwards / away. Simples. I do this within my normal lighting designs, and it's relatively cheap and simple to achieve with a bit of thought / planning.

There were a number of 'gaps' in the turnkey package they were supposed to be supplying to my M&E client. I went through a number of things with him, including the through-foundation services penetrations etc, and that highlighted a number of concerns; with whom was responsible for the slab matching the frame, windows fitting the openings, thresholds detailing ( for flush / level thresholds at sliders and front door etc ) transitions for services through the build fabric for larger bore services, and more...... I wasn't impressed tbh. BTW, they were not doing the slab, nor did they offer that option ( at the time ) so shared very little interest.

At least C19 nonsense has evaporated sufficiently now. It is manageable now, site CDM etc, but I just pay a site manager to do all of this remotely for me these days. RAMS is just a copy / cut / paste affair, and takes my chap about an hour to format site to site. Biggest issue with HSE will be fire, first aid, and dust control. Keep a cheap cyclone vacuum on site, and encourage hoovering vs sweeping up wherever practicable. Tags on scaffold is an absolute must, as a death from scaffold without a tag will result in a manslaughter charge.

Merry crimbo folks 🍻🎅🏻🏴󠁧󠁢󠁷󠁬󠁳󠁿👍

A 9kW electric fire connected via a 13a plug, but nobody could tell it was burning the wall socket out due to the 60-100 fags a day my parents got through. No wonder I can’t bloody smell or taste anything these days.

Lego.

If DIY then a lot here have used Midsummer iirc, but ‘we’ install Solarwatt mostly. Turnkey only, so no “supply only” I’m afraid.

Clients get told to do their OWN research, and to instruct us to crack on, or not. 👑 👆👎👌

Variable resistance created by an automatic bypass ( sprung ), installed immediately prior to the manifold rails across, flow and return, which closes as the resistance downstream becomes lesser, and vice versa. General health and safety foremost, and yes, flooring manufacturers stipulate max temps before certain types of flooring get damaged / adhesives begin to reconstitute etc.

I’m not a fan of an install without local pumps and blenders ( thermostatic mixing valves ) at the manifolds tbh, as without them you have to accurately control the flow temps and guarantee that they’ll never exceed 27°C, plus that type of setup also attracts expensive digital ( electromechanical ) mixers and PWM pump sets / CPU etc etc. Overly complex imho. Driving directly into the manifold rails also doesn’t allow for dynamic bypass, so you can’t really do this without PWM pump control tbh. That’s the exact same LLH I fitted for a recent client and it does the job perfectly. Primary pump in the HP circulates back on itself unhindered, and the UFH manifold pump ( immediately adjacent ) sucks whatever heat it needs as loads vary.

If the heat load is as low as stated, bloody good for a retrofit ( EnerPHit? ) his sounds like a candidate for a low loss header or very small wall mounted 2-pipe buffer with a constantly open bypass at the manifold. The manifold pump will happily ‘suck’ whatever heat it needs as and when so you’ll probably be fine with the LLH. If you go LLH then you’ll likely need a pump between it and the manifold, but if you go 2 port buffer you can just pump straight through it to the manifold from the pump in the HP. Doubt you need to complicated this much at all, just needs the water from the HP to be free running back on itself to smooth out demand vs relying solely on the value / temp of the return from the loop(s).

Put them on, see if anyone cares. Unless your neighbours hate you or it is obvious from the roadside then I’d say you’ll be fine.

Well, ‘we’ve’ got a few in without complaint or interest, and they are bigger than 9m2. Lucky for me I’m in Wales, and not many people care about much more than the price of beer down here. I shall proceed as planned ( or not planned lol ). “Death before dishonour”.
