That was me doubting, aka squeezing a doublé entendres out of it ( on the other, "now reduced" thread ) . My talents are wasted lol. Now, back to your dubious conduit porn ??

How many loans before a pool becomes "exhausted" eg each person has maxed out their comfort amount. I think to be fair this was initially raised to help poor old @ProDave out, so let's stay focussed on that as there's nothing worse than feeling that hope was within reach but then fizzled out in the peripheral white noise.

News ? ? Thats all ive been watching today

1) Agree an amount to lend 2) You state that the repayment need to be a min of 2 years / max of 5 years 3) You state any interest / fees / terms and agree the settlement amount. 4) You exchange emails stating the outlines of the agreement and each agree by return. 5) As its unregulated you hand over the ?and it's done afaics? There can't really be any more to it if it's on trust. ?

Hi and welcome @Simon Dave Please use the "Introduce yourself" section to tell us a bit about yourself and your project . Regards, nick.

And again, this forum shines brightly. To quote @ProDave, "this is more than just a forum". This is an extraordinary example of that.

Relax dave, I think the clue is in the reference to "lending", based on people's knowledge of you, your character and your known future worth. Im quite intrigued by this concept TBH, just as I am with this Bitcoin business. I believe this indeed refers to the money being loaned.

In your situation that's exactly why it there. Remeber though that my comments here are case specific to @richi's setup

No. that's there to protect the pump in a sealed system boiler typically. It will only open if say you turn the heating on and every radiator valve has inadvertently been shut, and the hot tank is satisfied. That arrangement would not use a PoR. If the automatic bypass were used for heat dissipation it wouldn't be very good as it would just circulate the very hot water back around the primary HEx, and you'd then be solely reliant on the latent loss of that and the short connective pipewort to dissipate the heat. ? That all depends, of course, where the pump is, as the pump protective bypass valve needs to be at the pump or before any downstream control valves. Thats the reason you always see these true setups with 1 x 3-port mid-position valves rather than 2 x 2-port ZV's as in the de-energised / park state a 3-port MPV always leaves a fully open path to the heating circuit so the pump overrun only needs to control the pump ( as opposed to the complex solutions first discussed here ). Proper heat loss PoR setups are designed to draw cool water back into the boiler to be effective. With gravity it needs to work in the event of a power failure, hence my further suggestion ( above ) of a normally open ZV on the DHW circuit ?

My head is up my arse at the mo with work, so I'll nudge this later, but this could be simplified and a bit safer with a ZV that is 'normally open' eg energised to close for the DHW ZV.

Keep the faith . He will finish it before I put the last 6 tiles on my bath panel . 3rd year this Xmas. God I need a few days off, ( but no work no cash ) ?

The heat in any boiler always goes to the PRIMARY HEx ( what the burned fuel actually heats ) and then from there if it's a combi it gets diverted to the plate / secondary ( DHW ) HEx. The oil boiler here will be treated as a heat only / open pipe setup as the huge amount of residual heat in an oil boilers HEx needs to be dissipated after the flame is extinguished. Every oil boiler you buy these days has a pump control terminal on the PCB which fires the pump and does PoR, likewise with any modern system or heat only unit. It's infinitely more problematic with oil and more again with an old oil boiler as it'll likely have a manual resettable high limit stat. If left to boil, then cool, with no PoR, inevitably that safety device will nuisance trigger.

I have to ask, with P2P lending in particular, what's the security based on ? Tbh I never knew such a thing existed, other than "loan sharks" of course. Tis a diverse place this .

If it's cosher, and you don't want it.....

"No need to squeeze them out ever again" for eg ?

You will still need a pump overrun ( PoR ) with that setup as it's a heat only boiler When the cylinder is hot the DHW ZV will be shut, and when the demand for heating is lifted that ZV will shut too, therefore creating a sealed loop where residual heat in the exchanger will be free to boil and knock the OH stat out. Any arrangement with PoR needs a path to a heat loss circuit ( which EVER that is ) which is open in the standby state or worse a power failure. Ok. Assuming the hot tank is staying as is long term and is still plumbed in and remains in commission. What I'd do ( as a long term / end solution ) is do the 2 x 2-port ZV's so you you have an s-plan, and energise the DHW valve from the 'heating off' terminal in the time-clock. NOTE : 28mm ZV on the hot circuit if it's 28mm pipe So, when the heating runs, the DHW ZV shuts ( from stored energy ) as it de-energises, and the heating runs through the heating ZV as per normal. When the heating demand is removed the heating ZV will close and the DHW ZV will open ( these will operate nigh on simultaneously so you'll never get a closed circuit as far as the pump circulation is concerned ) and and residual heat will then be free to naturally ebb away via the gravity circuit to the tank. The return water in the DHW gravity loop will be ambient ( cool / cold ) so will cool the boiler down nice and quick. As for normal DHW production, when you recommission to use DHW again, you just leave as-is but then connect the power for the DHW ZV to a simple timeclock for timed DHW. A nice side effect of this is you get to have a gravity DHW system but retain the option of having the DHW off whilst running the heating. It would need a tweak to the wiring to achieve that. No complex timers / non-standard controls too so ongoing maintenance / repairs are easy.

That's a good idea, seeing as there's rear access. I'm glad I inspire you to come up with these ideas

You robbed me of gold, and now he wants the silver too I doubt any mere mortal would ever get the flush pipe to soil pipe centres spot on enough to offer the pan on without issues.

Tres bien Rodney ??

Bugger. I meant to edit that out of his post so I won ☹️ ??

D'oh ? You'll be buying them ANYWAY. Take me now, Lord.

In an arrangement like the one you show in the Marley design, yes you can use equal branches, but I wouldn't in your situation as you have the opportunity to do a better and IMO more reliable install. Ive done as above in offices and nightclubs etc where there are 4 / 5 / 6 or more WC's in a row, tight together and no room to use y branches. The nightclub ones often blocked with any 'excess material' sent down so the rodding eyes we fitted got used a LOT. ( I know this because I DJ'd there and my ex boss did the install ). When you clearly have the opportunity to go Y branch......Y wouldn't you ??

So, another Geberit frame went in today. Looked to see how you can go rear horizontal exit with the gubbings supplied. @JIH Ok. So in the picture the black bits are : Left one is the pan connector which comes supplied too long and you cut it to length. That is inserted into the bent connector ( item on the right ) when you fit this as God intended. Middle is the 90x110mm reducer. Right is the bent bit ( pan connector receiver ) that gets clipped into the frame to make it a captive fitment. So, for this exercise we take the pan connector and affix the rubber seal. Then fit the reducer straight onto the pan connector as shown. That will take you out the back and push fit into a regular 110mm soil fitting. Bingo. No need to buy anything else as you have rear access to both the cisterns and can offer these on once the frames are in an the pans are on. With no rear access you'd need the captive element so the pipes don't push away from the pan when you offer it against the pan connector and flush pipe, but here you can just make the soil up in the service void and clip it all together nice and tight. If the pan ever has to come off and be refitted, then the pipework will be held by the fact the soil is all clipped / mechanically fixed appropriately.

@richi Why do you need the pump overrun ( POR )? Any residual heat will just go via the gravity hot pipes. POR is only required where lifting demand / call for heat closes any water path from the heat exchanger.

Result. Top bits of kit. ?
