No real need tbh, unless it's in particularly dodgy place.

This isn't going well for me.

That's me snookered then. Take me now lord.

In Ian's words, "long on promise, short on detail". I'm not qualified to comment on the insulation, but that advert has inspired my new plumbing brochure

Git

Clearly, the celebration here is that you found a good plumber. Im lost for words as to how this has been responded to, and can only hope that Byron will come back to me after his holiday and offer some resolve. I will most definitely be providing closure from this matter, through accounts of my own exchanges, by means of posting here accordingly with the outcome. Ill hold off recommending a screed company

It's something that gets overlooked when cutting holes in buildings / walls / ceilings tbh, so feel free

If you want to extend the chrome stub Chrome 35mm compression socket I use those plastic reducers but I fit the bent one in the wall so you can't see it. A few options here

That pic shows the tee. Is there a piece that you have that screws into that which leaves you a stub of pipe?

No dosh, no alterations. My days of working for free were during my years as a daft young man who went self employed. I want to go back in time and slap myself. ?

Plus 1 As the voltage goes down, the current goes up. . That means MUCH bigger cables, more complex voltage drop calcs, power supplies to fail and more. Feed the outside lights and power circuits from RCBO's which reside directly after the main switch in the CU. That will ensure that no circuits in the house get affected by outside faults

I love those ones, but if theyre happy to pay for it, let them fill their boots.

Ceramic ?

The grey stuff is compatible with most 15mm stuff, but does have the Achilles heel of being able to be rotated until the joint comes apart. One of the things I hate about JG but ok if you can leave these exposed and confirm their state prior to commissioning.

The point is to stop a fire melting the pipes and travelling through to the first floor joist space .

Don't let it get wet. It's done by weight in most places .

Something for nothing ? The video about the Innotech which produced Hydrogen from natural gas is quite interesting, but he stumbled a bit when mentioning that biomass may end up producing the electricity required to support the conversion process Still makes me wonder where the Hydrogen will come from when the gas runs out / is too expensive! Thanks for the video link, I was too knackered the weekend to think of something so simple. Now I realise the ecogen isn't a Combi ( my assumption sorry ) and that makes it a bit more relative to your application. A quick browse sees average MCS installs at between £5k to £6.5k. A regular system boiler would be circa a grand, so about £1800 fitted ( retro fit price ). That leaves you the £2.5k you need for your genny, plus between £700 to £2.2k to run it. Dont forget that the CHP baxi only produces 1kw when delivering the full 6k of the primary gas burning side . Best to yank all your insulation out and drill a few vents in here and there to increase your gas usage . ( been a long day, sorry ). With a low energy house you may struggle to get any meaningful electrical generation tbh, and I was reading about this from 06:00 to 09:00 this morning so have researched as much as I could before replying ( still not long enough to realise it wasn't a Combi though. D'oh! ). With the stand alone genny you'll be able to produce heat and or electricity when you need it most, rather than have the boiler dictate when you get additional electricity. What is your design heat loss in kW?

I've had a good read tbh and it's a tough one to call, because of your particular circumstances ( off grid ). As I'm quite familiar with your 'case' I'm privy to the fact that you'll have a sizeable ( non MCS ) Pv array, and that you are considering a chunky generator plus battery bank. As im 100% unfamiliar with this technology I'm on as steep a a learning curve as you are btw, so, I'm asking the questions as much as answering them The links. The ecogen The Dachs ( Sener Tec ) unit The Baxi unit is a combi, and only a 24kw combi, so at first glance doesn't really seem to be a contender for your property due to dhw production constraints. As producing instant dhw in any reasonable capacity is going to be non-sympathetic to your situation I'm pretty sure the Baxi can be discounted from this equation unless you see LPG providing a lot of the space heating where you could just ignore the dhw side, make that off to a local hot outlet ( kitchen sink / utility would be ideal but any hot outlet would do ), and zone valve the heating output to split between space heating and heating of the dhw cylinder/s. That would bring it back onto the list of 'possibilities', but one major upside is it's got a very low modulation rate @ circa 3kw. At that low output both the electrical output levels and the boiler efficiency would suffer, so again a complete bar steward to get this through without highlighting pros and cons a plenty. Next is the Dachs unit. A quote from Page 38....... "The Dachs is a micro CHP system to cover heating, electricity and domestic hot water demand. The output, reliability and functionality is suitable for small buildings with high heat demand as well as for commercial, office, public and multi-apartment buildings. The Dachs can operate as a single unit as well as in a multi-module system with up to 10 modules. Each Dachs unit can provide 5.5 kW electrical and up to 14.7 kW thermal (with condensing unit)." As you can't export excess electrical generation and CHP isn't eligible to claim RHI, you'll either need to be able to consume it, store it ( batteries ), or, most importantly, ensure that you've not spent too much money on producing it in the first place. The benefit of a simple generator over the CHP is that you can run the genny without having the issue of what to do with the produced heat i.e. you can run the genny in the summer without worrying about excess heat energy production. The benefit with the genny is that a water-cooled one can provide heat energy which can be gleaned for consumption ( via a TS ) and given the genny will most likely be used in the colder / darker ( little or no Pv generation ) months of the year, the heat energy created will largely be consumed by the property ( as it can charge the proposed large primary ( seasonal ) TS, the heating and dhw preheat TS and the UVC as heat batteries ) whilst the electricity produced is charging batteries and offsetting the immediate electrical demand. The only way to run the CHP for electricity is to store the bi-product ( heat ) as thermal energy in a huge TS, but that'll soon max out and the boiler will then go into standby. Then, if you don't use that heat energy it's been wasted as it'll be lost as the latent heat ebbs from the TS. From a glance, it seems that the Dachs is only really beneficial if your burning gas for any meaningful time during any 24hr period. With a well insulated, reasonably airtight house with low temp space heating ( Ufh ) and MVHR, your situation doesn't really match the criteria that these units are intended for. That coupled with no incentive schemes, in your individual case, plus the high capital cost makes them an unwise choice IMHO. So simple.

Ok, just mowed the garden ( another couple of hours I'll never get back ) ? Couple of things. Are the towel rads off the pre blended flow or off the manifold ? The bath feed can tee off and service the shower I'd have thought. Saves on one run and one less manifold port. Only observation beyond that is that the system is solely dependant on the cold mains pressure, and the dhw flow rate of the combi so those are major factors in this design

Fwiw, if there's no dependant kids / infirm occupants you can certainly do away with the second tmv if you wish. The tmv should be set around 50oC anyway so not going to cause issue for a normal household tbh. Personally I just like the hot water comfort of flicking the tap to the hot position and opening it and getting the exact same flow and temp each time regardless of what others are doing with outlets elsewhere in the property. Can't be arsed setting the temp, then it stabilises, then having to set it again, a proper pita.

Sorry for any night terrors, but I wet shave in the shower . Smoother than Ghandi's heel . The only thing id do differently from that pic, with hindsight and no pressure being a wonderful thing, would have been to put the secondary tmv immediately off the TS hot outlet. Upon reflection, and with 28mm hot pipework before it, there may have been a bit too much 'dead' cold water to draw through everything ( as it is there ) thus offsetting the benefits of running 10mm to the basins. It was a tricky install actually, with both high flow dhw plus energy efficiency being thrown into the remit. At the time my assumption was that the leg of 28 before the first blending valve would never be 'stone' cold, and the subsequent design was born. I don't loiter after jobs so can't really report on the actual outcome, but I'm reasonably sure that the TS, being kept hot 24/7, would have allowed a bit of heat to escape and reside in that first leg thus reducing the 'issue' somewhat. That install was done 'on the fly' so not too bad considering. Tmvs can be mounted in any orientation, I just wanted that as easy to lag as possible, hence the Munson rings to space the pipe from the ply etc.

Live by the sword......

Hello, and welcome Hair is a funny thing. My dad's family business was hairdressing and I remember my free haircuts well. I was not a dedicated follower of fashion My hair grows like I sleep with my head in a grow bag, and my dad used to say "you may go grey son, but there will be plenty of it". My BiL and I were joking yesterday about how our hair looked ( after our wives were questioning theirs ) and I told him he may want to sit down as I had some bad news.....then I told him he didn't have any. There was an awkward silence, then a few belly laughs. His hair was parted by Moses. Don't worry about wiring, that stuff practically fits itself, but do give us a shout when the pipes are due to go in

Sorry. I did have a moment where I thought I'd opened this post but was stuffed if I could remember what and when. Ebuild had a forum page where unread posts were bold, and opened ones weren't, but here the just disappear after you open them. Still getting used to this forum. . Catch this up tomw .

Long term solution.... Go to b and q and buy some thick shelves, cut them to size and forget about it. You can do it when you blah, blah, blah etc.
