@junglejim Does the picture depict your situation? Masonry build with a cavity?

The frames provide the support, the walls around them just hold the tiles. No need for ply or doubling up of anything. Done a load of these over the years and never any issues whatsoever, ever with the Duravit, extra-long projecting pans. 6’2” Canadian was asking if they would move, so I stood in my socks on the very front edge and bounced up and down. MBC TF house and all supports / studwork done in chunky timber, and client was going white waiting for the pan to snap off the wall (which it didn’t). These are rated to allow for a human to trip and fall onto them, so landing your arse down with a less-than-graceful ‘thump’ or slipping and falling onto these is accounted for; impact rating of 60-odd stone / ~400kg or something iirc. Just do NOT use the stupid gasket they sometimes include, instead I mask the tiles and set the pan back into a bead of clear CT1, tighten up and level off, and then remove the displace sealant with a load of cheap baby wipes.

Hi and welcome. Are you aware of the zero VAT rule, if you decide to use either a bulldozer or an excavator to knock it down?

You can have the heat pump tbh as most modern, inverter-driven heat pumps have a very low inrush current as these ramp up vs ‘turning on’. Also, if gas is available, you could go for a hybrid ASHP with a gas burner (Grant do these); whenever the heat pump becomes overwhelmed the gas burner kicks in to fortify output. They’re a bit pricy though.

I have to ask about the exterior 'screen'? Don't you feel it interferes with the views? Lovely corner windows, great views, and then you look out onto (into) the additional timber screens.

You'll be surprised at just how much you can abuse an 80a connection. You'll not actually be doing as much 'constant, full-wallop' consuming of the juice . These things are a lot worse on paper than in reality. You'd not believe what one previous client was running off a 60a connection previously, when I was approached to refurb and add PV, and that was a large property full of electric showers / all electric cooking / fully occupied, and a self contained annex with the same all-electric setup in there sharing the same supply.

You have a bit of luck, as the base of each handle has those larger 'feet', so I would just drill incrementally up in size until you get to where you need to be. If it's up/down, then maybe use the 5mm bit to just elongate to make a slot, vs making bigger holes, plus you may need to fit washers to the screws so they don't pull into the (real wood) of the door and then move back to where you don't want them to be from the tightening action (rotational movement of the pan head screws). Very slow and very steady wins the race, so don't do this in anger.

UVC doesn't give higher flow rates at the 50o+ temps? Combi's can't usually be compared. 3 showers is very good, at what flow rates?

Mostly pics tbh

You’re still always constrained by the physical max flow rate of water, whatever temp, through a combi.

My books are all still wrapped in the cellophane as I didn’t bother going for my NAPIT in the end; Covid put that on ice, and a change in career path (coming away from the coal face) put it to sleep. Maybe I should give them a read lol.

Yup. Nails are soft, screws are hard, and those bits (and the Erwin ones, as long as you buy the correct ones)) are defo rated to go through nails; I have these and they plough through nails with relative ease. Screws is a very different thing as there’s nothing other than diamond that eats those. The Starret bits do go through, but after a few holes / screws you’ll defo see the teeth beginning to fail. I treat these as a consumable and just but multiples of the go-to sizes and bin when they start to struggle. Same with flat wood bits, just buy cheap ones off amazon, boxes of multiples of 12/16/20/25/28/32mm and treat as disposable. If the know there’s a screw, try to remove it, if you’ve gone through nails, whack a screw in after to reinforce what you’ve removed. Another joyous day of house-bashing. These are the best ones imo, if you’ve a whole house to 1st fix for plumbing and electrics. LINK

Anyone experienced and competent, you meant to say

Yup.

SELV covers up to 50v iirc.
