Onoff

Presumably 25 ish turns of normal ptfe tape on this stopcock? Wind in well but don't wind back. Like with the bib tap fittings:

The nice man from Warmflow came back to me: "The boiler is best installed top and bottom opposite sides for efficiency reasons to make sure the water is circulating completely through the boiler and not having a hot and cold side, which will happen if the flow and return are piped on the same side. So if you changed the pipework to box the boiler in for efficiency reasons, you would actually be making it less efficient".

At least nobody can ever accuse us of finishing early... ?

Demoralizing, when you realise you've started more projects than you've got years left to be able to finish.

Don't be silly, those indents act as a key for the render.

Weirdo.

No idea. It's actually in what's a bit of an attached outhouse that's been prettied up. After a bit of net searching I found, see the top line: Looks like I won't be moving that pipe then!

I've emailed Warmflow.

Nor does it fit with Onoff diy ethos.

Because I want to box the boiler in and it's a pita having that pipe there. I can only get a very slim timber frame in level with the window reveal. To have a bit of u shaped pipe sticking out of the wall will look silly. The full height boxing in will be easily removable as an aside. I do share your concern despite what Nick says ?) and am thinking "diagonal" flow from bottom right to top left is needed. I might contact Warmflow. My guess is when installed this was just easier and they didn't fancy messing around with or didn't have the 28mm 45deg fittings Nick mentions. Could be wrong, I'll fire off an email to Warmflow and report back.

Yorkshire or end feed? Wonder if I'd get a bend in there...I could bend a bit of 28mm at work.

All joking aside it looks pucker. ?

First problem, the original 28mm pipe clips seem pretty short. <25mm from wall to centre of pipe. The IntaKlean isolators are 70mm wide/long. I suppose I could just turn them through 45deg. I'm going to swap the boiler flow pipe from one side to the other but it's offset by about 20mm. I wonder if the vertical pipe might just move across a tad when the clips are off? Might end up a little off plumb...

When I did mine my first thought was wider door to the bathroom. Then new, strong ceiling joists in case a hoist is ever needed. Bath is slightly sunken so bath floor is level with the bathroom floor. Making an area open plan for the elderly can be an issue. If they fall, they're falling further and hitting the floor harder. Long term I see a plastic garden chair and me being hosed down!

It's a sad fact of life that anything shipped with screw terminals particularly can loosen in transit/ storage. Consumer units as a good example. People throw them in but only check the security of the connections they have to make, trusting the prewired stuff to be be tight.

If you haven't bought a Fugi Cramer tool kit buy one now. https://www.amazon.co.uk/Cramer-Grouting-Silicone-Profiling-Applicator/dp/B07H8K5W8D/ref=asc_df_B07H8K5W8D/?

Euphemisms abound..

Sorry, what's F&E?

Thanks. Was just thinking less to drain down to add the cleaner from the header. As you say though, I'll need to drain down to fit the Magnaclean! I'll see if I can borrow a 28mm pipe slice from work. I'll do at the weekend. Kid less then so nobody but SWMBO to complain they're cold! I'm going to have to sort this one I think. When I've drained from here before it takes an age to drain, hardly comes out at all to start with. This isn't anyway the lowest drain on the CH system. Down to 4 different floor levels in the house since I did the bathroom! ? Looks like 1" and 2" spanners.

Who knew? I removed the covering board from the 28mm flow and return pipes to the boiler and there's a bloody great gap where I can see straight into the loft. Must be some heat loss up through there! Plan is to put the Magnaflow in the right hand pipe, return to the boiler. Can anyone see why I can't move the flow from one side top to the other? It's not quite in line though: I've been up above the dormer ceiling and though I can't look inside, I've measured the header tank as best as. I reckon there's about 20L of water in it. If I tie off the header tank ball cock then drain off say 30L of water via the boiler drain cock can I chuck my 2L of system cleaner into the header? Then I assume let refill then bleed the rads.

Seems I can get a grant for 2/3 for something... The intent is a manifold. There's a temp sensor run to the centre of the bathroom floor. Kindly sent to me by @PeterW many moons ago.

I must download it. Did my bathroom layout on AutoCAD:

@Nickfromwales, morning. Appreciate the tip ref the low loss header and that, size wise, would certainly allay SWMBOs fear over losing under the stairs storage space (for ever more crap). Assume I fit a manifold then with provision for at least 7 circuits, roughly: Bathroom loop Bathroom towel rail Study Kitchen Lounge* Diner* Bedroom NB: No loop in the hall or stairs room itself. (* Going to be one big room eventually, not sure if one loop is big enough). Would that "small" 25kW llh be big enough for all those loops? Maybe I'd be better now arguing for a bigger space for a bigger tank? Should I, as an exercise, calc the eventual runs of pipe now, before I venture too far. Similarly, I aim to EVENTUALLY do away completely with the downstairs single pipe system. If I then heed the sage advice given here over the years and fit a UVC or TS the obvious place for it is under the stairs. If there is a "tank" already there it's easier for me to sell the idea to her. One ideal I suppose is that whole under the stairs area gets given over to me for a mini plant room. An alternative perhaps is our plan for full height cupboards either side of and over the bathroom door entrance to house the stacks of tat! (You'll walk through a corridor in effect made up by the cupboard sides). Maybe one side of that gets given over to house a tank? PPPPPP! ?

I don't believe it.

As @PeterW says, on the return before the boiler! Pro_Installation.pdf
