I was thinking of hiring but then as I will need to use again, perhaps buying something is more sensible. I would like to get something by Thursday / Friday... any of these do the job of fixing plasterboard to battens?

I'd ideally like to keep it under £100 unless resale would be good.

When checking if we could use a certain set of bifolds, I asked our Building Control guy about this and I specified they were not laminated, and he said 'either laminated or toughened'. Our joiner was of the same opinion. I'm sure others have said only laminated. Might be worth you asking your BC as thats what it comes down to.

Hey onoff... here is the tap it’s going onto if that’s what you mean

Ok I have been taking a look at what I’ve got and have a quick question. Ive got some straight tap connectors 3/4 inch. They have an extra washer in the packet and it’s angled... Do I put it on the end? Which way up? Also the shower instructions say to use ptfe but that’s not necessary with these is it?

As an update, I tried liquid soap and it didn’t work. Think I’m going to try sending it back but it’s quite scratched now alternatively i I can keep it, leave the rubber washer out and seal and fix with silicone ??‍♀️

That makes sense. I think because our shower mixer is concealed that was why I haven't planned on using them well i will certainly post with questions when I come to tackle it... maybe over the weekend ?

so they are, thanks!

So there's like a continual movement of hot water going to and back from the studio, then when someone wants to use it it's there?

In this pic, what is the finished look? I'm wondering what the copper bits are for and whether we need them. I can post a pic of the tap I am thinking of.

Yes so for additional context it is a small place and has one proper bathroom, then the shower room in the studio. But it's generally a home office. At the moment there is just the two of us but we are youngish and might expand beyond that in the future. We also might not stay here forever so the sizing should be right for whoever might move in to a one double and one single bedroom house with one bathroom and a non residential studio.

Also @JSHarris and @Nickfromwales the installer recommended down here suggested a 6kw sunamp for the DHW for just the house. Just for interests sake I thought I would tell you that. So I had thought with this new plan of upgrading to 9 so it could cover the studio. If we got the 9 and used too much water, could it be charged up during the day if we were on octopus agile rate - as it has dips in cost during the day too

Thanks @JSHarris and @Nickfromwales ! To clarify, we dont have the intention to use PV for a long time, we cant afford it, but I like the idea that we could do it in the future. Not sure if that changes anything you have said. I think I am ending up on the same page in terms of burying a pipe so it's good to hear that advice. Originally when it was mentioned I didn't like the idea of taking up all our shed space with an UVC and running our hot water to the house from the shed, but not having a UVC, and running just the hot water underground TO the infrequently used shed seems much more reasonable. Um, what is hot return circuit in? I understand the words but dont know what it does or is for.

Yes, he said he was waiting on sunamp to confirm whether they would/could do it but it was his understanding that it would be fine. So is this the one I want to be able to electrically charge it? http://www.bublshop.co.uk/sunamp-uniq-e-hw-hot-water-store-heat-pump-pv-model/p2038 OK thats interesting. It's actually less likely that we'll get a high temperature heat pump (that is high enough for the sunamp) than it is that we will get solar electricity panels in the future. But it would be OK to connect solar panels at a later date too?

Love how the bubbles light up! ?

Thanks @AnonymousBosch! I'm going to 'just bloody do it' and see what happens! And post photos on here to see if anyone has any thoughts. I'll probably leave the pipes in the main house to someone who knows what they are doing, but for our little shower room in the studio I'll give it a go... I spent ages on screwfix website ordering bits and pieces. Their shopping cart is crap and kept deleting things so I ended up missing a lot out. But hopefully today I will have what I need and can start having a look at it all together. ?

Thanks Jeremy. This was actually the sunamp recommended installer (that charges £600) who said this.... I do think they are quite new to sunamp too but still. He said he was waiting on sunamp to confirm whether they would/could. So you can't buy the electrically heated sunamp and then connect it to an ASHP later (this is what the installer suggested)? Can you connect it to solar pv later?

Thanks everyone for your help. Now thinking of just ordering the sunamp from bublshop (are they the only off the shelf shop?), brings up some questions I've had lurking in my mind for a while. When going through the sunamp recommended installer down here, they mentioned that we could get a high temperature heat pump that heats at 62 degrees, and that they are talking to sunamp about whether they will update their controller software to allow the sunamp to charge a couple of degrees less than it does at the moment. I saw one of these heat pumps on ebay but wasnt ready to commit to the idea, but if I see one again, is this a legitimate thing? Can sunamp actually just update their software? It's not about the actual material not changing state until the exact temperature? He said we could get everything now and if sunamp update their software we can just update it in the future to make them work. My second question is, is the mains electricity charged sunamp the same as the one that can be charged by a heat pump? p.s. sorry this is segwaying a bit, but I didnt want to mess up other threads

Ah haha thanks! I can stop wondering now.

Thanks both. Maybe this is the best of both worlds as keeps things simple, and doesnt waste space. Just a bit more effort. This seems off topic but is a question emerging from potentially locking in the sunamp earlier than planned, why can't high temperature heat pumps do domestic hot water directly? As in, not using a tank, or a sunamp. Is it because of flow rate?

Thanks Jeremy - I think I confused things by talking about the Sunamp, as the quote wasnt related to that as the sunamp is going in the main house. I just meant we were trying to avoid immersion heaters taking up space on the property in general, which was what led us down the path of the sunamp, and now we might end up with an immersion heater anyway That probably didnt clear anything up... sorry I'm a rambler If it helps the attached are our electrical plans... we are probably going to reduce the number of downlights by a fair amount but used this to get quotes. How difficult would it be to bury an insulated pipe between house and studio (about 6m) to just use hot water from the sunamp in the house? We could get the sunamp early and put it in the studio until we are ready to move it (or leave it there). I think you (or someone on buildhub) might have even suggested this to me when we were talking about just having an ASHP and immersion heater.

OK so... I went back to our electrician who fitted our outdoor socket and he also says he doesnt have an issue with the shower (he's got our full plans for the house too), however, he said if we go for an immersion tank then we would save ourselves about £100 because of cabling and labour. Although, we'd then pay £350 plus extra costs of the tank (an extra £1-200 compared to instant heater) so we end up paying more. And an immersion tank takes up more space and *could* run out of water. Also the whole point in getting a sunamp in the main house was because we didnt think we had space for an immersion tank and now we might be putting one in the workshop again... ? I dont know what to decide. It feels simpler to go with the instant water heater... but also seems against some good advice! EDITED because I got the saving wrong

I can get the rubber ring off and then it goes over, but when i put the rubber ring back on and try and pull it on from the back it still wont come ?i'll see what we have got to grease it

There are two but this one is way bigger so has to be this way around. It's like it almost fits, but gets stuck on the rubber inside the ring. I could try taking that out if it isnt glued

nope ?

I mean it serves me right I guess, but I actually would have bought a 75% more expensive one from soak but I didn't like the proportion of the wall plate...
