I would point out the ‘defects’ and let the joiner come back with a reply, no different from any part of the snagging process when sometimes builders don’t follow drawings and it make decisions based on time/ effort. hopefully you have issued all drawings electronically and his quote has no omissions stated.

Try BES. They sell everything!

I’ve fitted these before and can confirm they can be ceiling mounted and ducted away

I like the current set up rustic appeal, appreciate its just concrete kerbs but not a fan of the plumb slate thing

He’s meaning you need to switch the output side ie the 24 colts you mention above and not the 230 volt AC side I wouldn’t do a drawing. Ie you’ve found these.

Are you hanging over them all day, ‘supervising’ That can be a tad tiresome, clockwatching lunch breaks?

Manage remotely with Wi-Fi controlled devices/feedback

Broken mortar on the ridge tile?

Have you looked at the hafele website I mentioned before. they do a lot of shopfitter based gear inwill draw something tomorrow for you to use the Normal switches

I think that’s the best option, UFH on wet and towel rads electric, gives redundancy, ability to utilise as a dump load.. I use a smart socket)out with bathroom) and set a time schedule for mine to utilise cheap night time tariffs.

The UFH will have a thermal effect on the cabling, so allow for this in calculations, a conduit/kopex/ duct makes it easy to pull cables in.

Maybe a cats paw, better for keeping surfaces intact.

With that size of property there must me some PV going on the roof! coupled with ASHP/A2A it’s a no brainer

Your BCO is the person to discuss this with then.

Can’t see a problem lots of electrics fitted under boilers that fit in kitchen cupboards hiweber if it does become an issue you could fit the loxobne unit in an IP enclosure?

Glad it went well a good milestone

Sure building control. don’t think the OP has ever mentioned a building warrant in any of the threads

Planning has already been approved

https://trystanlea.org.uk/heatpumpradiators some interesting reading from someone who works in monitoring, self installed a heat pump too.

https://www.houseofwindows.co.uk/downloads/fensa-guide.pdf have a read of rhis

Tell him you are getting a third party to give independent advice on the roof, if they say it’s acceptable you will pay, if not you will be looking to seek monies back for the roof. likely he will bugger off

If you have no diy experience please look for a qualified roofer to save you going through this pain a second time NFRC would have a list… good luck

I’m afraid it looks like a £50 tarpaulin, indeed my garage has had a £50 tarpaulin that’s been 100% reliable for 2 years until I get going

How can you add a window if you cannot get access to outside?? like the rendering, fascia soffit, guttering You really need to address this issue, or what will you do when the neighbours call the police and the builders walk off the job??

a mini split is for heating or cooling not ventilation. you need a ducted vent system, you could incorporate heat recovery too in a single unit and run supply and return ducts to each room or a single unit in the style of a wall fan
