Hello,

I have a room in my house, which also serves as a laundry room, entrance in winter, small storeroom etc ...
I count the renovated, this room is not heating, knowing that I already have the washing machine, I would like to arrange a drying tower there.
what does it consist of:
a tower in wood panel or other, a system to be able to hang clothes in it quite easily, and a bottom a small heating fan (additional car heating for example in 12V) in order to be able to dry the laundry faster, because in the laundry room , the laundry does not dry at all in winter.
Of course, don't worry, the laundry is outside.

what do you think of this idea?

This idea is very interesting, and not only in winter ...
In summer, drying the clothes outside when the neighbors are making grilled sardines means flavoring their sardine laundry ...

More seriously, on the old continent, the habitable m² are worth gold. The problem is therefore to dry the laundry as quickly as possible, using the least amount of space possible, and spending the least energy possible ...

Each achievement will therefore depend on the configuration of each home.
We removed the dryer when replacing the boiler (space issue and militant energy approach), but this posed new problems that we have not yet resolved ...

Congratulations therefore on this subject, while waiting to see the (realizations) modern of this type of dryer.

We have never had a dryer at home, an ideological question too.

this tower (size of a fridge) would simply be there so as not to have the laundry in the dining room as it is currently. I like everything has its place each place for one thing ...

there is a bathroom upstairs, but the laundry does not dry very well.
If this basic system works well, I think the consumption of a small fan with heating is ridiculous. Maybe even put it on a small battery and with a solar panel to power the battery ...

I will do my first tests as soon as I have my mini heater, in an old metal cabinet.

Yeah, but.

In winter when you put the laundry to dry in the house (so a heated volume):

- the energy necessary to evaporate the water must be provided by the heating ...
- and then you have to evacuate the humid air so throw it all outside (unless you have a double flow vmc)

morality, put a monobloc air conditioning in a box with your linen, it will consume 4x less electricity than your idea of ​​heating ...

I do not totally agree,
indeed to dry the laundry there hi and we put it in the main room, so yes we use the energy of central heating, and wood fireplace. No vmc in the house, because finally saw the type of house (1900) which is not airtight. And the humidity in winter is 25 to 50%.
vmc releases too much energy outside the home.
opening windows regularly is more suitable.

I installed. A vmc but I cut it after 1 year.
because I am not convinced that it is a good idea.

but cac is another subject.

how a tower (box) with a mini fan heating in 12v, would consume more than an air conditioning ???

I don't think it will work. Stirring the air is not enough.
It is also necessary to evacuate the water vapor.
To dry my clothes, I hang it in the kitchen in the evening before going
to bed. The house is heated by a stove / boiler
wood that is placed in ... the kitchen.
In the morning everything is dry, there is nothing left but to put away.
It has been going on for a few years now and I don't think it
have a better system. In my case it allows to humidify the
house which would otherwise be too dry.
It is more rustic than a tumble dryer but less expensive to use.
J despite a whole tumble dryer whose resistance has been unplugged.
I use it when a tissue has been left in a pocket.

In fact the principle would be a small heating blowing low position and openings high positions. Holes or opening on the facade etc ...

thank you for your advice rabbit

Because water has a latent heat of vaporization 2.2 MJ / kg, or 0.61 kWh / kg. So to evaporate 1 l of water it is necessary to supply this energy.

If the laundry comes out of the washing machine with 4 liters of water in it if you have a machine that spins well (1000 turns or more), with the losses, it takes at least 3 kWh to evaporate all the water ...

Either you have dry air (in summer) taken outside and reject humid air outside with a fan: it doesn't cost you anything, apart from the holes in the walls, it only consumes slabs, it's like spreading the laundry in the garden but it works in the apartment.

In winter when you will have cold and humid air available, it will not work or very slowly. So you are going to replace your heating with a radiator ...

With a thermodynamic machine you consume 3-4x less.

Otherwise you take a wringer machine that rotates at 3000 rpm, in 2 minutes it's done ...

too bad the idea was attractive ...

thank you for your response

Hi sapper3873
If you use a dehumidifier, (280w for 0,6l)
you spend as much energy as heating,
but as a bonus your laundry will normally stay dry.
(and you will not have to heat the laundry room to dry it
(me it is the cellar which took moisture from the linen).

The dehumidifier makes it possible to sanitize humid rooms,

In humid winter as in the middle of a hot heat wave,
lowering the humidity of a room increases comfort

In summer, lowering the humidity below 65% allows perspiration to remain effective,
while above 70% we suffocate by overheating for lack of
cooling by evaporation of perspiration.

It also serves as a dehydrator for garden products or for drying,
low consumption if enclosed in a reduced volume, large carton.
