no, a good old mechanical bimetallic strip (as in water heaters) is suitable.
so you would buy the wind turbine and the alternator but not the electronic controller?
Preheating by wind
no, a good old mechanical bimetallic strip (as in water heaters) is suitable. Okay, now I'm more comfortable
so you would buy the wind turbine and the alternator but not the electronic controller?
This seems to be looming, yes. Ideally, no batteries, no transformer. Wind turbine type, alternator, cable, heating element, that's it.
I also meditate on a trick to accumulate energy for 24 hours, kind of mega watch spring or counterweight system to compensate for the absence of batteries with a pendulum to balance the flow when no wind but in this plan I have no leads yet. I'm going to work on it.

Like, what kind of alternator? If it's a car, 50% yield so forget about it.

> kind of mega watch spring
10 joules can lift 1kg from a height of 1m
1 kWh = 3600000 joules
if your wind turbine produces 10kWh during the day to store it in a spring it will be about the size of a train ...
if you want hot water, store in hot water

the spring ? truly the energy storage solution of the future! compare a toy with a spring motor, or with an electric motor and cd battery or ... don't you have the impression that for the same weight the electric toy works 100 or 1000 times longer?
another comparison of the same kind, a quartz watch with a needle rotates its hands for 1 year with a tiny battery ... a good old spring watch must be wound every day
takes a big car suspension spring compresses it and measures the force
energy = 1/2 force x stroke
do the calculation and compare with the energy that can be put in a battery of the same weight .... the difference is huge
spring without interest

why the thermostat would require a battery ... there are 36 types of existing thermostat, just put the right one
the simplest are the bimetal thermostat ... we said that they did not like the direct current 220V ... but your alternator will never make direct current ... even if it does not make the 50HZ sends the variable frequency and basta
well known it is not easy to understand with the dynamo of bicycle which are alternator ... and the alternator of car which make of the continuous one because the rectifier diode are assembled directly in the alternator
in a wind turbine it is not very smart to mount the rectifier diodes in the wind turbine: it is better to lower the 3 wires of the three-phase and put the rectifier with the rest of the electrical equipment

you should not let yourself be impressed by the enormous power in high winds which are very rare
http://www.gual-statoeolien.com/Doctech.pdf
looking at the doc of a serious wind turbine we see that it does not put an alternator capable of using the strong wind which are too rare
http://www.vergnet.com/pdf/specs-mpc.pdf
we see that they put an alternator which reaches its maximum power for 13 or 14 m / s depending on the model, which proves that the stronger winds are too rare for us to make expenses to take advantage
with a conventional wind turbine, when this maximum wind is reached, it automatically reduces the incidence of the blades so as not to capture more power than you want, and reduce the effort on the mast
with your massive wind turbine there is no adjustment possible, it will have to be very solid to support the high wind: which makes the huge weight that we see on your doc ... and the weight makes the price
a classic wind turbine to do the same power at 15m / s will be much lighter
theoretical power of betz = 0,355 SV ^ 3 = 0,279 D ^ 2 V ^ 3
to make 1,3 kw at 15m / s if the efficiency and 0,65 you need a theoretical power of 1,3 / 0,65 = 2kW
D ^ 2 = 2000W / 0,279 (15m / s) ^ 3 = 2,12
D = root 2,12 = 1,457 m
there is nothing to hesitate about a 1,5m diameter propeller wind turbine will always be less expensive than a 4m diameter and 1,5m high thing
and yet another trap, the wind speed announced in the weather is measured at the top of a 10m mast without obstacle ... for a wind turbine to benefit from the same wind you have to set it to the obscale: when there is a house you have to put it at a double height from the house ... or 10 times the height of the house
putting the wind turbine on the roof of the house will give it a considerably weaker wind than the normal wind if it were better placed
the classic wind turbine is easy to put on a mast because it does not pull too hard ... the vertical axis wind turbine, larger for the same power would make catastrophic efforts on a mast ... and in addition does can do nothing to reduce the effort in high winds

OK, spring is not the idea of the century but a counterweight system is feasible in the barn where it would be installed.
if you want hot water, store in hot water
This is a good idea to calculate the volume of water in the tank to cover, say, a week of preheating. Not easy!

No danger of sending variable frequency AC to a bimetallic thermostat?
in a wind turbine it is not very smart to mount the rectifier diodes in the wind turbine: it is better to bring down the 3 wires of the three-phase and put the rectifier with the rest of the electrical equipment.
The wind turbine will be on the roof of the barn so easy to put all the paraphernalia below in a room fitted in the roof expressly for that. Anyway, if the thermostat and the heating element are not disturbed by frequency variations, I don't see the point of a rectifier. These are losses in addition to me. No ?

http://www.gual-statoeolien.com/Doctech.pdf
I don't let myself be impressed, don't worry . If there will be 5m / s, on the roof, on average in winter or +/- 90 days, it will be normal or even good for the region and the season. The annual average is 5,5 m / s in the ZDE CC Pays de Meslay-Grez and CC du Pays de château-Gontier where the wind turbine will be installed
with your massive wind turbine there is no adjustment possible, it will have to be very solid to support the high wind: which makes the huge weight that we see on your doc ... and the weight makes the price
The barn is capable of supporting weight without causing it to fold an additional knee. It is a 17th century barn designed to have a split slate roof. Today with its sawn slate roof, we are able to add 50 tonnes on the back without her noticing.
a conventional wind turbine to do the same power at 15m / s will be much lighter.
Forget a conventional wind turbine for an installation at this place. Countryside, trees nearby and farm building with all that implies turbulence, a conventional wind turbine will never deliver the goods to a similar place

Hello Cyril!
You answer to Dedeleco who will not be able to answer you because he was banned having not understood after a 2 week vacation the modo permanently struck him out at the request of several members including me!
NB: he can still read your answer and itch to not be able to revive you!
