You've not got any pubs near where you live?

Thermal imaging for airtightness testing is a load of nonsense AFAIC. Heating a house up and then running around outside before it cools down will not show you where it's leaking inside. Indiscriminate on a good day, utterly useless on a bad one. Snake oil if you ask me, and bloody expensive snake oil too. "No".👎

Expert status is now upon you. 👊

It basically sheds any excess energy, above a set point, to ground ( via the earth pin ) instead of dissipating it via a sacrificial component ( as an SPD does ). All good, give it a whirl.

TBH I'd go for the Belkin, as it's rated at 13a and offers a guarantee against failure of devices plugged in to it. Download the MI's from Belkin and read up a bit to see if it says no pumps / inductive loads over x number of Watt's etc.

It's mandatory, but wont solve this particular problem. The OP needs a filtered supply to remove spikes / soften disconnects when the grid drops. An SPD isn't for that and won't 'trip' in these instances ( or the world would go potty as that would be £200 or more each power cut, plus the wait for an electrician to attend to replace the SPD ). Remember that an SPD is a single shot device and blows like a HRC fuse would.

All wastes are top access ( aka “self-cleaning” ) with nothing underneath than waste fittings. There’s nothing to ‘get at’ so don’t worry about that I waffle on considerably here;

It needs to be a filter, vs a one shot SPD etc. That will give protection from frequent fluctuations, and not need expensive replacement by an electrician ( after every power cut / surge ). The shower is a digital mixer so no big power supply. The one linked in Screwfix should be fine. Or; https://www.argos.co.uk/product/9473188

Greggs sausage, bean and cheese melts are available in the N, E & W so not a problem. Down South it's a cartel.

AFAIK "have" to. It's to limit the current on the consumer tails. @ProDave?

If there's a 100a in the supply head, and there needs to be a 3rd party SF as the tails are >3m, then you're supposed to de-rate to 80a in the SF.

What is there not to like about this chap? 👍

Most is down my back Makita 18v hairdryer lol? SWMBO can then share my batteries.

Hi, and welcome. I'm a very big fan of MBC Timberframe's turnkey slab / frame package, and if you want a stress free / as seamless as possible a build then that's a great option. Not the cheapest option afaik, but very quick and simple with the majority of the paperwork / red tape / professional services all encompassed. I don't know of any other TF suppliers that actually offer this as turnkey, and I do know some suggest this but then fall quite short on delivering. Go up and see MBC's factory, and you can even go and see builds in progress, which may be beneficial to you. Other companies offering this likely do exist, and I'm sure others will post here accordingly. Happy hunting, and good luck. Don't forget to search this forum for everything else, as there's a massive amount of good information and support available here .

If you were happy, could you share their contact details here please? Subject to their agreement also.

Yup. Total and utter nonsense. Stands to reason then that she would be far too busy that day to spend any discernible time at each property, eg helping the client locate and cure any leaks / improving the score whilst on site. No thank you.

It's a bloody bathroom! Go in there, drop the kids off at the pool, wash your grotty bits, and then get out of there? Toothbrush charger / docks are now commonplace, phone ( ? FFS ) try charging it before you go into the bathroom to take that "important call" ( defo go on hands free, hygiene first people ! ). Speakers? The amplifier goes inside ceiling mounted speakers, been fitting them for years. Vanity mirror lights? Never needed anything other than a 230v cable behind them ( and then you can also have the shaver socket incorporated into it. The world has gone mad. Doubt we'll see upwards of 1kW through a USB for hair tongs any time soon.....

Largely due to the amount of grog they consume The beer displaces the water in the human body, so they cannot conduct electricity. Very wise people, we could learn from them me thinks. Stick that in your 19th Ed

Copyright infringement alert NOTE: I only did this like a ring as there was a large cold mains accumulator to boost the cold mains, and the client wanted to be able to run 4 showers simultaneously, plus other cold devices ( appliances ) running too. So an extreme case.

Still nicer to have reliability, and infinite capacity on tap to fortify solar / batteries etc. Means the generator can go bye-bye then too.

The £20k will be a far better investment afaic. I've priced a few off-grid domestic systems, and quite often we're up at way over £60k when it's all done and totalled up ( for a system that will actually let you live a normal life ), plus with off grid you can forget charging an EV whilst using anything else electrical. Get the contestable works done in-house, see if the roads can be mole'd under instead of closed and excavated, and save wherever you can. But in a nutshell, stump up and pay for a grid connection is my strong advice.

What size joists are going in the floor, and how much insulation are you installing? The UFH will need a significant amount of insulation under it to perform well without huge running costs. What will be supplying the heated water? Existing heating system T'd off to a single room UFH kit?

Shut off the UFH so the primary's are only flowing the the FF heating eg so whatever the pump has to offer is only pushing water to the FF rads. Leave that run for an hour or two and revisit to see if the air ( which is the problem here for sure ) has made its way into the rads. Do you have / did the plumber install an AAV ( automatic air vent ) on the upper ( flow ) pipe feeding heated water to the cylinder?

That’s the problem with a heat pump Nobody knows until you fit it in it’s new surroundings and switch it on. Ambient air temp, target flow temp, external air temps etc etc all go towards the output power. Output power is only ever stated as a hypothetical, and the design / suitability / expectations get managed by “running the numbers”. Each instance differs so it’ s down to the individual circumstances which will dictate ‘power’.

So basically a 2-speed system Where do you think the “noise” goes?
