  1. gonna be someone elses' chinesium surely?
  2. the inner layer is white on all of 'em...
  3. each will have a spec for the maximum screw length. Looks like the DS50 does 55mm, dunno about the Parkside.
  4. @TerryE which post are the photos in please?
  5. you need a way to force the flow out of the floor loops and into the willis...
  6. Yep. I was able to mod my manifold to get flow out into the Willis, but only because a. it had a bypass and b. said bypass pointed at the return of the Willis. And I have the Willis underneath the manifold so have the chance of convective flow anyway. You'll need a pump... unless... where does the braided hose at the far right go? Tee into that and connect to the bottom of the Willis, and go from the top of the heater to the supply into the manifold. Cap the return. Sme of your flow will be diverted through the heater and the mixer will then sup heated water.
  7. Because mains electric is Alternating Current. The V (dash dash) is Direct current, you'd use that around a car or to test batteries etc.
  8. Just the 600.
  9. It's V (squiggle) 600 you need, round to the right.
  10. Where is the pump going??
  11. and the meter is set to VAC, not DC correct?
  12. I think they're seperate. Looking at the menu for the non-inverter controller it does seem to have two temperatures but the timer programming bit doesn't allude to DHW and CH schedules.
  13. looks like it's using it's own programmer to do the flow temps based on times?
  14. no reason you couldn't use a poured thin screed over the timber deck either. Our FF is 50mm hemihydrate over caberdek , on 254 pozis @ 400ctrs, with a span of 4.7m. It's impressively stiff and quiet.
  15. Yes, the motors are known to fail and are replaceable. Hopefully your plumber also does electric. Not all do...
  16. the valve works when it gets a supply of electrical power. You haven't yet confirmed that this is happening. Once you do this than you can confirm that either the valve (it's motor on top) has failed, or instead part of the control circuitry upstream (UFH wiring centre/ stats/ timeswitch/ ASHP controller even maybe)
  17. only niggle is that those stats have a pretty wide hysteresis so a "too-low" setting may let it run for a bit and then just... stop.
  18. tried hitting it a whack?
  19. ... once you've verified that it's failed and there isn't a supply/ control issue...
  20. Correct fitment is indeed terminal box down. I don't think I've ever heard of one failing ever but I do know that the housing is light-gauge copper and the chances of unscrewing the element out of an elderly one are small. Hence some now being sold as a soldered-up unit. interesting note also that in their normal application- from the bottom to the top of the DHW cylinder- running the heater for a minute or two to get hot water moving means that you can then open a tap to a low flow rate and have continuous hot water. The willis basically bypasses the tank...
  21. yep, done this a number of times at our current place.
  22. nominal bore of a black-iron pipe of that size IIRC?
  23. found the blurb... NIbrochure_0119.pdf datasheet-v5.pdf
  24. lucky you're not in the RoI then, where modern MLCP pipes are still used in true imperial sizes... They're a kinda copper-coloured creamy brown...
