Ventilating A Room?

[Ken's Deputy 4,456]

Looking at the likes of @NEWKID here.

I have two, conjoined rooms. Big one and a small one. Big one was a 'barn'. They just poured a concrete slab down as a floor. Thick as shit. But it's still damp in there.

Little room, I had floored. Membrane down and concrete top. Damp

This isn't a damp I feel in the walls though. It's the air. Books and wood get white spot in there, in pretty short order.

I'm no builder. But, I figure, as the only ventilation in there is a small fireplace? Where can the air go?! So, I'm thinking about putting holes in the door out. Top and bottom. Grilled vents.

Reckon that'll do any good? I simply can't afford electricity. Dehumidifiers or Bar Heaters are out.

Thanks.

Lose the HID lamps and swap to LED's...invest in some quality extractor fans and filters

Get a decent dehumidifier one that you can set to what humidity you want. Bob’s your uncle no more problems

Knaps, air bricks aren't an option. Trust me on this. That's why I'm thinking the chimney feeding into, and the air vents in the door, letting it out, should do the same thing?

I thought to myself, today: That chimney lets air, from the outside In. ... Then what? Air can't suck up and down. So, it'll just sit in there. Surely?

Doesn't take Einstein to figure out it needs an escape route. Can't use air bricks. So, use the door.

I've actually done exactly that with the door on This room. CO alarm's shut the fukk up since.

Yes mate, that should do it aswell like you say as long as theres air flow it should do the job eventually

There is a system that works purely on convection with no electricity required. Basically there is a vent through the wall that leads to a large radiator type thingy, double walled so when the sun hits it it warms up the air causing it to rise and escape through a vent in the top. That causes a through draft inside the room as long as there is  a vent to allow fresh air in. The  convection thingy needs to be on a south facing wall.  Alternatively, fit a solar panel to power a small DC ventilator.

I recently used a decent dehumidifier in a house and over four hours it took 8 litres of water out of just one room.

I'm afraid there's Nothing going through these walls, Pix. Just not happening.

And, what ever I do has to be on a shoe string. Like; I have the tools to put a couple of holes through a door. The money to pay for even quite nice vent covers, to go over them. But, that's about it.

Just to chew some fat; It's funny. I have a fukk off big kitchen, okay? One chimney. Two doors. One vented.

This room adjoins it. One chimney. Door now vented to the kitchen. Room's okay.

Other side of the kitchen? Small 'bedroom'. Now my tool / work room. Door unvented. But, chimney and vents into the roof. That room is Arid!

Rooms I'm talking about? Absolutely fukking Murder! One chimney. No other ventilation. Walls seem fine. But the Air must be shit. Because anything paper or wood I put in there gets white mould on it.

See? Only defining difference I can see is that the air, in those rooms, with the adjoining door wide open between them, comes down the chimney. Then is stuck.

Figuring some nice, brass vent covers should fit in

Ever put a Humidifier and a Dehumidifier in a room, sat back and watched the fight?

Knock all the walls down, but leave the door standing
