Whether right or wrong, I’ve had 4 extensions done on my bungalow and none of them have mortar below the DPC, only above, and haven’t had any problems in the last near on 20 years. I have read people mortaring under the DPC but not sure what it brings really, plastic is never going to adhere to mortar, not strongly anyway, and the weight of what’s above will keep it where it should be

No better people the ask than the worktop template people, they’ll have come across is many times I’m sure. I couldn’t recommend anything as I don’t have an island unit

As above, what council are you under…they should be a department and more than a single person, although you have a named contact, others there should also be able to come out and advise. May also be worth copying in the entire department email address along with your named contact, could help move things along… and the other thing, they could just be on annual leave

Was watching an episode of the great house giveaway only the other day from series 1 and that had a property on it with a single skin extension and the chap said it needed another skin to be mortgageable

Definitely much much better than 2G, and they also do one with thicker glass on the outer pane which lessens it even more, designed primarily for use in bedrooms, so may be worth looking at that unit

Definitely not ivy. If its a shady wall, you could look at Hydrangea Petolaris which is a climber

Mines wall mounted, and yeah some sort of sound absorbing is a wise move, maybe not to start with, but as the unit ages and the fans inevitably get slightly unbalanced, it will help to stop any vibrations making their way out and about.

How about just getting a shorter one? https://bpcventilation.com/collections/ductwork-silencers/products/quiet-vent-semi-flexible-silencer-range

Ahh I think I know what you mean, I remember reading or watching a video that the bumps will pull in when it dries, I got a few on one of my walls and no such luck! Hope yours did. As for the reason, I’ve absolutely no idea why it happens

Photo? Don’t forget to spray a little water on when you are doing your final trowels to help your trowel glide over it without pulling it up (may be what you are describing?)

seems even manufacturers are going to need to retest or reformulate their products for our planets ever increasing temperatures

Really interesting that, not what I expected. So essentially there are losses and the sunnier it is the greater they are, but even then it’s minimal and saves buying another inverter.

wonder how that comes about? Just can’t imagine it from my own install. Have you done this and observed the output difference?

I believe Tesla powerwalls do this, but it’s a hard thing to achieve in the UK as in the event of a power failure, any generation or potential export should turn off or island, and for that reason most don’t operate the whole fuseboard on backup, rather just a backup socket for emergency loads to be plugged into. Maybe someone else knows more about this, but mine certainly doesn’t as an AC coupled. Don’t agree with East and West connecting to same MPPT, my east and west panels are both active in differing amounts simultaneously, and in winter east does far better than west. Either use a separate inverter, or get a triple MPPT one to handle all 3 strings, these are widely available as normal and hybrid. A good question, do you get the feed in tariff? If you do then don’t go hybrid, as it will wipe out a lot of your income.

Work out the airflow capacity you need for your volume, and then double it so you run your unit only ever at 50% (less the better for noise), and then keep an eye out on eBay, loads of units come up, many are brand new and much less than buying from a store, they’re often mis-specified units which get sold on to recoup losses
