    what panels are they?

    Now I'm gonna strip a connector today to confirm it to myself but it's my belief that the collet doesnt get "done up" on the white domestic stuff. The collet bites into the pipe automatically and grips tighter as line pressure increases like with any pushfit. All the twist does is move the outer stop such that the collet won't depress surely? The horseshoe clip has been used as a positive *lock* for years on the beige and black systems. regardless I'm still waiting to hear exactly what has been happening to cause Nick's comment: " the crap design from undoing and flooding your house "...

    no, the rotate bit disables the collet in the same way as the horseshoe stop. So why have I been successfully just pushing pipe into fitting-s per the MIs- of mission critical fittings for years and (other than pipe collapse of vinyl and nylon pressure tube and hardening of O-rings) never see leak or failure?

    Nick, I've been around JG and their collets for what? 30 years on gas air and fluid systems. How come you see problems with their domestic water fittings that don't occur anywhere else? How do these fittings leak? If it's fully inserted and under pressure, the pipe aint coming out...

    any chance you've accidently got 16mm pipe?

    what are your ground conditions?
  7. dpmiller
    there's Tees with something running upstairs there.
  8. dpmiller
    or you just get them all lifted and queued at one end and position by hand?

    no friendly farmers locally?

    would coke work then?

    Certainly in terms of fixings etc the likes of GSE are very definite about the number of nouting points and batten sizes etc to stop even their flush mounting system being sucked off the roof. There's detail in the MIs

    it's not really management, just overcurrent protection and low-voltage switchoff. /my first Dewalt lithium pack was bought dead and cheap in the hope that it wasn't really dead but had a dry joint or similar. Infact the cells has just turned off and giving each 3v for a few seconds woke'em up and it then charged fine...
  13. dpmiller
    0v often just means "turned off" bt the cells own internal BMS rather than dead/flat. It needs to see volts to waken up, per @Miek above. If the whole group is @ 3.2v , what charge rate are you at? How much charge has actually gone in?
  14. dpmiller
    why not box and tile the whole thing then if it's just for appearance-?

    @ProDave broken blade sadly
  16. dpmiller
    can you fabricate a ring of something to fill the gap?
  17. dpmiller
    fans need to be a close fit in their housing otherwise efficiency is reduced, the air basically recirculates.
  18. dpmiller
    our guys did neither of those.

    Why would the TF company need mains power?

    certainly L&Cs take on hybrid is to switch from ASHP to the other boiler when ambient temp crosses a set point, it's configurable with DIP switches to temps betwen +5 and -5C. Presumably they reckon that the COP loss plus defrost cycling means the alternative fuel is cheaper in those circumstances.

    You know, I've just re-read your story and brief and it's amazing just how similar it is to ours. And this is what *we* ended up with. dorm093-350-Miller-NI-A.01.pdf dorm093-350-Miller-NI-A.02.pdf
  22. dpmiller
    Some heatpumps have built-in control for the boiler using similar strategy. The Peak/ Lailey and Coates unit for example.
  23. dpmiller
    You'll need to get a design SAP done for Building Control so that'll be a useful bit of modelling.

    thee are some good "book plans" out there to get you started. We used this guy http://www.irish-house-plans.ie/index.html Shaun is really good, he totally re-drew one of his base designs to suit our needs. he's got a wide range of examples and you might be able to find portions of some that suit.

    ^and it works. very well.
