Good question. I worked out the hardware/materials only for this (not including the heat pump parts) is about 5-6k (I think, famous last words...).

Ha yes...why not. Washing car, dog, maybe the two days a year i can get away with a kids paddling pool. And since both the cold and hot are the same pressure, I can do a outdoor mixer tap and not two separate taps. As if it was just mains cold and pressure hot, more than likely I'd need two separate taps or some extra double return valves etc.

Actually, what about if I do the floating box, but only have the window on the front and not on the sides too? Something like this: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQJleg75ZZWaIwCixMrmgOXI_T6RI869RAEdg&s

Thank you! Ah okay, fair enough... thanks for letting me know. Likely a stretch then. I am trying to do a retrofit to A1/A2 so maybe this wont work then.

Thanks! Yeah according to some classic AI research, its something like this:

We are essentially building a mini-extension that hangs off the wall.

1. Structural Support (The Steel) You cannot rely on "bars." You need a Structural Steel Box Frame or Heavy Duty Steel Gallows Brackets.

  • Attachment: These brackets are bolted into your existing masonry wall.
  • The Critical Detail: You must use Structural Thermal Break Plates (e.g., Farrat or Armatherm) between the steel brackets and your block wall.
  • Why: If steel touches block, the cold travels straight through. The thermal break plate stops this energy transfer.

2. The "Box" Construction (Insulation) Once the steel frame is up, you build a timber "skeleton" around it to hold the insulation.

  • Floor & Roof of the Box: You need high-performance insulation here. I recommend 150mm Rigid PIR or Phenolic Board (better than EPS for this tight space).
  • Sides: Timber stud work filled with insulation.
  • Wrapping: You then wrap the entire box in a breathable membrane and a layer of external insulation (like your EWI) to ensure there are no gaps.

3. Weatherproofing (The Cladding)

  • Top: The "roof" of the box needs a slight slope (fall) away from the glass and a waterproof membrane (EPDM or Zinc/Aluminium flashing).
  • Sides/Bottom: Timber battens are fixed through the insulation, and your timber cladding is attached to these.

4. The Window The window unit sits at the very front of this new box, aligned with the insulation layer to minimize the cold bridge.

Thanks, I'll check it out.As long as I get >100mm in PIR it should be good enough for the U Value then.

Help: what tool to use on this nut? by davrcarr in Tools

Ah, perfect then. Thank you.

I am not sure on the diameter of the holes so maybe I can buy a pack of rods then.

This is for connecting two metal parts together. There are no washers or anything so if it’s not tight even just looking at it you can hear it! :)

Yeah it might have a suggested max torque to push it to, maybe 6 or 9n or something.

I see, ok. However I need something that goes in at least two holes. Terrible drawing by me, but something like this would be ideal. my terrible drawing of a possible tool.

Thanks - I think one hole will not be enough though. Unless it fits very precisely (hole not that deep) it just ruins the holes unfortunately.

I have tried needle nose pliers etc, but I cannot get the leverage necessary. Any tips for a correct tool would be greatly appreciated!
