Thermostat and insert fan

[antoinet111]

Hi guys, a quick question.

My Deville insert has a two-speed centrifugal fan, I would like to couple it to a thermostat to let it run at low speed overnight until it's cool.

so, I think to couple a thermostat of this kind pushed to the max at the exit of the air.



what is your idea?

Goods.

This is very possible with the addition of an air flow rate depending on the home's T as at home, varying continuously from zero to cold focus to maximum if warm focus instead of limited to 2 speeds.
Many circulators have such an incorporated thermostat with thyristor and a semiconductor T measurement KT.

a simple system, one off would be enough for me.
it would work, on the other hand, I wonder if, it would stay in time, it is simple, and rustic, I would ask a heating technician if I in one choppe.

This kind of simple thermostat works more than 10 to 20 years on old simple boiler, if of correct quality !!!

So no problem, but it is also necessary that the air circulates if the home is much too hot, so 2 measures of T, that of the hearth in the exchanger to evacuate the heat if it is too strong to force the circulator to turn and that of the room to be regulated if the fireplace is at a low heat not too hot to turn if the room has cooled down.
But no problem to operate this, just put the thermostat that controls the circulator which should rather be T min end of the fire to stop when the incoming air becomes cold.

I will try, it is not expensive.

I would make a return, thank you.

I just installed a fan 2 speed for the hood of my insert.
The temperature "regulation" is very simple. This works with a simple clixson (bimetal switch) which may not start up fast enough for a few minutes (also depends on the arrangement of the piping) and turns off at around the time, instead of stirring air. lukewarm.



As it costs that we can take several to better target the desired temperature and trigger once the high speed, once the low speed etc ....

thermostat of this kind

of atmosphere at 20 € rather for fridge:

Antoinet111 with bulb is as good, and more reliable because T adjustable at will as needed.
But he is limited to 35 ° C, a little weak.

The cheap interbimetal are mainly used as safety in case of overheating and therefore less reliable for a large number of off-stops
I prefer this one universal bulb that I use to 15 €:

and to 12 €:

but, like that of flytox, with the electric wires in the hot air at more than 100 ° C, not very recommended whereas the distant bulb avoids to bring the wires in the hot air.

For my insert I prefer the one with proportional thyristor which regulates the flow of air to the temperature, which maintains its constant T and allows to heat quickly with a lot of air with a strong outbreak. !!!

With this, a potentiometer and a simple CTN or KT probe to control:

or this simple that I own, adapted to 220V

Hi, I do not have the gear, nor the time to make a montage, not the knowledge either.
I am going to move towards a simpler editing.

it's a pity that the proportional m would have much more, but the second speed made a lot of brothel, before the tv it would be too much.

also, thanks a lot for the links, really interesting.

This exists commercially in many extractors for chimney insert to 150 to 300 € approx.

Example to 163 € 2 fan group page

Leroy Merlin is annoying, it is impossible to refer a page falling on the next time !!!
Quality is also debatable !!
You should have had the thermostat set instead of absurd bivitess to 20 € less !!

Hi, it's really too expensive like trick.

it will take 10 years before making it profitable.
