Recover calories on the pipe of a wood stove

I deliver the extracts of the departmental regulations to you. (valid for all departments)

ARTICLE 53:
Kitchen heating or hot water production systems by
combustion
53-1 - General rules (AP n ° 2549 of August 5, 1982)
The evacuation of combustion gases to the outside of heating, kitchen and
hot water production is carried out under the following conditions:
‹Installations of appliances using liquefied gas or hydrocarbon fuels must
comply with the provisions of the regulations in force (1);
‹Installations of appliances using solid or liquid fuels must be
connected to a flue gas evacuation pipe.
53-2 - Drainage pipes
A combustion appliance may only be connected to an exhaust duct having the
draft and thermal insulation characteristics provided for by the regulations in force (1)
(2). The external openings of these exhaust pipes must also comply with the
current regulations (2).
Any repair, reconstruction, raising, modification or addition of conduits
flue gas outlet must be carried out in accordance with the provisions of
current regulations (1) (2).
All measures must be taken to avoid siphoning, whether it concerns
flues or ventilation ducts.
The connecting conduits serving the homes must be visible throughout
course, easily removable and kept in good condition.

Except in the cases and conditions provided for by the regulations in force, they must not
enter a room other than the one in which the home they serve is established. Their journey
should be as short as possible. Their section must be at least equal to that of the nozzle
the device they serve. Their assembly must be correct, in particular their connection to the
fixed duct, to avoid any risk of obstruction.
The construction of flues, that is to say fixed, horizontal or
oblique, is subject to the rules for the construction of flues, in particular those
aimed at thermal insulation. They are fitted with buffers, especially when changing direction,
to allow their sweeping.
When the connection of a combustion appliance to a flue is compulsory,
the appliance must be connected directly to the flue. It must not be connected:
‹In a construction stove with chest or oven,
‹In a chimney with a heat recovery device forming the bottom of
chimney and obstructing normal cleaning,
‹In a fireplace hearth constituting an open hearth, except permanent arrangement ensuring
normal draft and sufficient tightness.
These provisions do not prevent the installation of a heat recovery system on
the connection duct, even subject to making the necessary arrangements for
maintenance of an efficient draft and the emptiness of the flue.
In any event, such a device must not be installed at the outlet of a device whose
the combustion rate is only regulated by the air intake.
It is established at the bottom of the fixed duct or, failing this, on the movable duct of
connection, a fixed or mobile device, such as soot box, soot container, connection tee,
intended to prevent any accidental blockage of the duct and allowing easy cleaning.

I'm going to tell you a real story that I lived 10 years ago.
I worked in the petrochemical industry, and every year I had a fire safety course.
That day, I had an internship, and the professor was the fire commander of a barracks; he was very impressive from all points of view.
That day, he told us to come into this room, and each in turn, you will be called.
That day, my turn came, it was fire training, I came running, because it was a fire simulation.
The commander said to me while shouting, there is fire in this electrical cabinet !!!
He said, I'm going to open the cupboard with a shovel, and you're going to extinguish it with this fire lance !!! always shouting loudly ...
I said BUT !!!, he said your face, and do what I tell you.
Three times I said BUT !!! we can not send water to an electrical cabinet ...
Finally, I sent the water, and directly he said to me "CLEAR CONNART, YOU ARE DEAD" ...
Conclusion, sometimes you shouldn't listen to the authority.
There were 23 colleagues .... 20 died ......
Yours

[Christophe]

Uh is this story true?

I don't quite understand the fall of the 20 dead ...

[Cuicui]

I plan to recover calories from the pipe of a wood stove to heat the water tank when the solar collectors do not work (snow, lack of sun).
I first thought of the coil inside or outside the pipe, but that would have made dismantling for sweeping complicated. The pipe is not made of stainless steel and I do not want to set it on fire to clean it, otherwise it is annealed, soft like a pie chart and rust quickly.
This stove pipe first rises vertically, then leaves horizontally for about 1,5 meters towards the duct in the wall. I intend to recover the heat only on this horizontal part which until now heats the ceiling (and the floor of the attic).
I am thinking of making a kind of thin and flexible radiator formed by copper pipes connected by copper sheet. This insulated top radiator is fixed to the ceiling and partially envelops the stove pipe. It does not prevent the disassembly of the hose.
The calorie recovery will probably be modest, but I hope enough to maintain the hot water tank if the fire burns day and night.
The circuit will work with a small circulator and a thermostat.
Of course, there are also the kettles that heat constantly, but having hot water at the tap is also good ...
I hope to tell you more this winter.

I guess there are 20 who obeyed the order and only 3 who refused ...

Yep, 20 colleagues obeyed the orders of an idiotic chef (it was a simulation of an idiotic chef)
The 20 knew that they should not put out an "electric" fire with water. And yet they obeyed orders.
It was a simulation, there was no electricity in the cabinet.
But the commander considered us dead, and stupid.
Since that day, I have been able to say shit to a chief, or to a law.
This commander opened my eyes
Excuse the mistakes of French ....

*************************************************
Once, I wrapped a coil around the nozzle + insulation; the result was not great.
Anneal the pipe by setting the chimney on fire? No, because the water continues to circulate in the coil when I put the fire on the chimney.
Now, with the coil which is in the stack gas, the result is acceptable BUT ... my circulator is controlled by the regulator of the solar collector (I installed a switch, which directs the regulation towards the collector, or towards the chimney coil.
At the beginning, I had put the circulator with a beast termostat on / off, and the result was very bad.
So, now, the speed of my circulator varies according to the T ° of my coil.

[Christophe]

It was a simulation, there was no electricity in the cabinet.

Ah ok you reassure me ... so it was a false simulation because there are many exercises with real fire ... I have a friend who made the firefighters in Paris and he drooled ... and I don't think he was simulating

[krashman]

This is the regulation, after you do what you want, I would not continue on the regulations for chimney sweeping, I think it would have the same effect.

But hey if one day you sell the house dismantled all before, it would be silly to kill people.

hello, little digging up of subject, in addition to season.

site with good things and surely good ideas for the do-it-yourselfers.

here is a thing of not bad besides my coil behind my wood stove. to have.
