Our chocolate cabinet is situated in a corner and creates quite a bit of heat.
This obviously means it's fighting itself to keep cool in summer.
Our rear windows are barred and grilled so we can leave them open all the time and creates a nice breeze through the shop.
This breeze totally misses the chocolate cabinet.
How big a hole and how close together can I drill a hole in a wall so that I can get some of the breeze into the corner?
When I drill a hole the dust is dark grey and the building was built in the 30s.

Bump.
Sounds like block.
Could you cut a 100mm hole and install an extractor above the chocolate cabinet with a flap vent on the outside?
6" hole with a core drill is relatively easy - maybe even 8" Much bigger than that or several of those close together the wall might be somewhat weakened and if its a supporting wall thats an issue
I the problem is having a cupboard made of chocolate tbh.
How far apart would 2 X 6 inch holes have to be?
2 storey flats above us.
Hah I was wondering what middle class lunacy was a chocolate cabinet, until I saw the shop part, carry on... :p
...you could switch that Aircon unit on! 🙂

duuno - a foot or so? Just a guess
Piece of piss

Eat the choclates, problem solved
Can you use a simpler option of pointing a fan at the cabinet (ideally at the cooling fins/grille) to create some airflow around it?

got me as well!

That would seem the choose to me too. Keep the heat moving outside.
Buy a fridge
Oh god that's it kicked off...
Jesus Mark what were you thinking.
What heathen puts chocolates in the fridge.
I could tell you all about drilling holes in walls but it is boring
Applause for WCA
Dredged up from a joke I told at my Dad's retirement party at a International Association of Hydrogeologists event. He was a hydrogeologist - drilling for water in shitty parts of the world.
I was told I had to make a speech about how great my Dad was and what great life it was being dragged from the arse end of Thailand to Darfur, to no where anyone ever wants to live in Sudan...
I was a petulant youth and didn't have a great relationship at the time. I stood up, smiled at the audience and said "I would like to tell you about the exciting life Dad lived but it was basically boring" and sat back down.
Cue awkward silence followed by one person in the audience getting the joke, laughing and then loudly whispering to a couple of others. It took about 5 minutes to spread across the whole audience but I got a round of applause in the end.
Another solution, although it does involve a new fridge but might be less disruptive than having to empty the whole shop to avoid grey dust on everything.
Can you get a fridge where the compressor unit sits outside, like with the Aircon unit? That way the heat from the fridge doesn't heat the shop and it fights itself less. Only downside is that in winter more heating might be needed inside.
Also if you haven't already can you put a door on the fridge or get one with a door? I know it's another job to shine it with windowlene twice a day but fridge will use way less power and people will poke the door not the products unless they are actually buying.
PS I have no idea how much shop fridges cost and that may blow all your profit for years or you may already have super duper modern efficient fridges.

Still, prepared you for the reaction your jokes get on here....🤷♂️
Slowol ,there's more details on my super exciting electric meter thread.
Fair enough that is a super posh, and pretty up to date fridge. Getting the heat away from the compressor more efficiently should in theory help efficiency by lowering the temperature difference between either end of the heat pump that does the cooling. As the maker doesn't do a remote compressor option could you duct cooler air in from outside directly into the compressor house at the base of the fridge?
As for hole drilling you can chain drill a hole any shape you like for ventilation if you don't have a core drill then knock out the piece with a cold chisel.
I hope the chocs are a good earner! That's a lot of investment and electricity.
Technically you can drill any size of hole in any wall, depending on the drill size...I think I might have missed the complicated part or something...
Masonry bits are usually bout 15mm though, for electric cables, anything bigger and the possibility of a concrete wall is proper equipment, a standard 15mm masonry bit is about a tenner, 3' long and will bore 3' of sandstone on one charge of a battery gun..just, as a guide.
If it's through to the outside wall it's the same as a central heating vent, you get a plastic cover thing that stops rats going 'look everyone, a door to a chocolate cupboard'
Behind that wall is the office which has the windows to the outside.
I’m thinking big hole up the top and if that fails small hole with extractor at the bottom. This will keep Mrs zips feet warm in the office.
If it helps, when we drilled an 8" hole from the inside of a room outwards using a clutch drill, to prevent mess (and trust me it causes a LOT of dust!), I placed a plastic biscuit / cracker tin/box over the site which had a circle cutout for the drill bit and a smaller hole in which I gaffer taped the Henry hoover tube as suction. Worked a treat (requires two people).
