Heat my house with the air from my veranda?

[kumkat]

if I had made the link correctly, the idea is technologically attractive even if the fan is too tight,
but does that justify a solar panel and a battery instead of two mechanical regulators?

Yes and no ... it depends where you place the ventillo and how many m of cable you need to lay ... It is case by case. It was you who said above that you didn't want to feed stuff 24/24 so I don't really know what you want

You can do without the battery: it just acts as a timer in the event of a decrease in brightness ...

Either way the best is that you test with an unregulated fan to start with.

(there is an external cladding which is a little singular but it had no place to do otherwise)

it is especially the 12 volt kits requiring to have 230V / 12V transformers permanently connected which I do not want ...

my air intake in the house will be opposite the veranda and under the fireplace
all my cables and sleeves will go underground so no prob

thanks for the link, I'll watch that

I think this is the crux of the matter; bring into the veranda a volume of air equivalent to the volume "pumped" and bring out of the house a volume of air equivalent to the volume pulsed.
Extractors, as powerful as they are, cannot beat an overpressure or vacuum part.
And so much the better, we have to breathe

The hot air comes out of the veranda from above for the house by opening shutable at rest with a fan and a similar opening below shutable automatically at rest with another fan allows the cooled air to return to the veranda spontaneously balanced.

Totally agree Dedeleco.
But we just went on 2 pages of 1 fan, 1 thermostat and 1 hole in
2 fans in 2 holes with 2 thermostat + shutter grids

AND in addition we did not solve the problem of the volume of air to pass.
(Okay, we have no data concerning the veranda, orientation, volume ...)
It would seem logical to me to have "low power" fans that run for several hours in a row (especially solar = zero consumption) than large ones that stop 2 hours after 15min of use. It seems more comfortable to me and less risk of destabilizing the main heating.
What do you think?

Small fans are enough to change the air in the veranda while the sun heats it in winter for a few hours.
If 10m2 on 2m50 high, or 25m3, a very small fan of 25m3 per hour is enough !!!
Above all, a shutter valve is required if the fan is stopped without sun.

I rather estimate around 100m3 I will make a footage this weekend.
You know where I could find on the web this kind of shutter valve stp?

Let's say that as a base and without big investment, valves for hoods or dryers can do the trick

not stupid thank you
