Ok, had a reply. 510mm for filter AND the heat exchanger is plenty. Fan is small so no issues with that. Door is 440mm projection when open. If you speak to Nick or Will at CVC and mention my username and the forum he will give you a discount off the Brink unit ( if you’ve not purchased already ). I organised the same thing for BH members wanting unvented cylinders and buffer tanks with Trevor at www.Cylinders2go.co.uk That offer still stands. “Every little helps” etc etc. ?

This is his last warning before we move to DEFCON 5. ?. Put it all together in the same wet sealant session. Resistance is futile.

Borderline IMO, and that’s if the installer is the one to hook up, test and commission and NOT the OP. Chain is as strong as it’s weakest link. This is new works, not existing, so it’s illegal work for both the installer and the OP. Not at all. The BCO comes to witness the works at strategic intervals, only allowing such works to be covered up / over AFTER they’ve been to visit, witness, and agree the works have been done correctly. Unless your GSR guy has x-ray vision then how can he say the integrity and execution of the installation is safe? Simple, they cannot. There is no exception here sorry; GSR person 1st fixes, GSR person completes and commissions. Anything else is imagination and interpretation for justification of one’s own actions. No sale.

That stuff not so easy. That’s up a few levels from CT1.

Yes you will.

Do as your told. ?

Through a dwelling, not just a wall I do apologise, I’ll get to this presently you (expletive deleted)er….?

~30 years of every gas fitter I’ve ever worked with telling me the same thing is good enough for me to go on. Gas “rules” seem hopelessly open to the interpretation of DIY’ers and over-confident self-appraising buffoons a-plenty. Just deem yourself ‘competent’ and crack the (expletive deleted) on. ?. I doubt you’ll find it, as I couldn’t even get definitive answers on this from the GSR themselves, ( when this came up here a while back and I found myself up against another brick wall …..) Do your own thing, if you live alone and nobody will ever come inside your property, ever. That’s ‘OK’ apparently, but if you cause the death or destruction of someone else, you’re liable. Why I struggle over conveying this is just utter disbelief. It would be less of a battle to move @pocster’s walk-on glazing onto a new owner.

I’ll get answers on all the above from my go-to guy at CVC Direct.

Every gas fitter I’ve worked alongside for nearly 30 years, including multiples of domestic and commercial installers, would all disagree. The likelihood of a fire, vs the robustness of soldered on gas is not a valid debate not walk away from soldered joints, afaic, but also, good luck to running a gas pipe right through a residential dwelling without having exposed compression joints.?. Every single fitter I’ve worked with has instructed me, implicitly, to seek out and cut out any such compression joints and replace with new soldered sections. No, no, and thrice……no.

Sometimes, I wonder why I bother.

I’ll be working on one on Tuesday. If you can hang on I’ll measure it for the minimum requirements?

Yup. I spent 2 days back and forth ( at my expense ) trying to get the curve right. Vaillants own tech guy just told me to ramp it up and walk away or I’d be there forever…… OK if it’s your own system and you can give up the time necessary. I still doubt it’ll make a hot of difference in a well insulated / high performing dwelling. Definitely a place for it in lesser energy efficient builds / commercial, but when a property loses 2oC over 24 hours then you have to ask why you bothered…..

Weather prediction vs compensation so to say. Interesting. My experiences of weather comp ( Vaillant ) was not great. Hopefully things have improved.

Every install I've ever done, ( immediately supervised and signed off by the GSR fitter I used to work with ) has had soldered joints. Oil is different, compression or leaded solder IIRC. Apparently the issue was with the more brittle / different composition with the unleaded solder, but I could be wrong about that ( been a while since I worked on an OFTEC registered job and legislation changes may overrule me on this.

With UFH pipes in a thick passive raft, and a cellulose-blown frame, do you really think WC’p will be effective given the likely very long thermal time constant you’ll end up with?

A couple of mm a second is plenty of pace, after all you don’t want to get 900mm down a 1000mm tile and then shell the edge in a rush. How do you find the last inch to nothing on the cuts? On the grade 5 stuff I really struggled with I also then had issues with the tile breaking away before the machine completed the cut. Some foul language came out of me on that job. I ended up cutting into the finish side an inch, then turning the tile around and then cutting right through to meet that starter cut. Just go slow and steady, it’s not a race! Cleaning up with the diamond cup afterwards is sadly the likely way forward if you want super-fine finishes.

It’s not the best pipe instal, but the compression joint ( and olive ) will have confirmed to grip and seal onto that without issue. I doubt you’ll have any problems tbh, but 2 mins with a pipe bender would have done this the world of good. I’m surprised at how many plumbers don’t own one, but some seem a bit scared of them. Either that or they simply cannot be bothered.

Always a tax to pay when convenience shopping though Good that they’re covering everything though, so a silver lining to any RHI clouds.

Then your RHI payments will buy a few rounds of drinks. They’re based on your heating ‘needs’ so payments will be in the gutter.

I was referring to the HSE arriving AFTER there has been an incident. ….or advise, offer reason why, and also give further advice on how to execute such work to make the best of a bad practice in light of “Although one chap did agree to certify my installation in the new year if I went ahead and installed” ?

What is your DEPC showing you’ll achieve?

Nor is there any attention to detail in the execution of the installation of things like sheet PIR insulation, as it's installed by site workers who get paid on volume, not detail. Their rates are screwed down too, so no incentive to go "above and beyond" as you often would get from a stand-alone builder / sub-contractor. The public get to buy these after it's too late to inspect the work, or they just don't care enough to ask to. One new build on a site is was on back in the day had the deposit-paid clients turn up mid build, and demand a full refund, as the workmanship was just horrific. The site was full of horror stories which ended up in the local paper. If covered up in time though, how would anyone know........

Under a run of base units would be what now? "Surface mounted" that's what.
