Question wood boiler assembly with accumulation

[turbozender]

Hello
I am installing a wood boiler with 2 buffer tank 700l

I also have to change my electric balloon by a bigger one

my question: is it possible to use the old one (150l) as is going to expand for my heating installation


2e: tell me what you think about this




thank you in advance

1.If you make an assembly with open vase, yes. Otherwise, no.

2. If I understand the diagram, I do not think it's good. But I have a big doubt about my understanding.

1 mounted vase vase
but I saw on a site that there was vase without membrane so it equates to my balloon with the hot water outlet clogged



2 / it's the party balloon / boiler wood of which I am not on

the connection on the existing fuel circuit is ok
it works since 3 year with an old boiler wood / coal

the I replace the boiler wood by a more powerful for which it is able to warm the balloons

[Philippe Schutt]

1. I had been taught that the air dissolved in water in the long run.

2. yes, I guess it worked. You had what I had called in an old post a dormant loop that is active only when its circulator turns.
But here, let's say that the ambient TH is "on" and that the wood boiler is hot and the balloon cold. the balloon circulator will pump a mixture of hot water (from the wood boiler) and cold water (from the balloon)

Finally, I do not see the usefulness of your check valves. what would cause the water to flow in the opposite direction?

[turbozender]

1 / ok I'll buy a 100l expansion vase if I find a competing mag that sells it


2 / the anti thermosyphon outlet of balloon is used to avoid that the return radia heats the balloon (it did not heat old boiler wood in fuel mode)


the 2e which is between the wood and balloon should serve precisely created a loss charge and that the pump out balloon pump only in this one

but now that you talk about it I'm not sure that's how it should be done (do you have a solution?)

the circulator at the bottom left will be enslaved to the t ° water boiler wood or the t ° of the wood boiler smoke (I did not bend over)
which will prevent the boiler wood from being held in t ° and create calorie losses coming from the balloons

thank you for looking at my project

[Philippe Schutt]

it would surprise me that there are thermosiphon effects when circulators turn. finally...

I do not see a simple solution, except to wait until the ball is hot to take advantage of the "wood" heat.
But with some contactors we get better:



The control laws of the valves could be:
If Tamb "on"
-If Tbal off and Tbois off then Vfioul on and Vbois off and Vbal off
-If Tbal off and Tbois then Vfioul off and Vbois on and Vbal off
-If Tbal on and Tbois then Vfioul off and Vbois on and Vbal off
-If Tbal on and Tbois off then Vfioul off and Vbois off and Vbal on

If Tamb off
-If Tbal off and Tbois off Vfioul off and Vbois off and Vbal off
-If Tbal off and Tbois then Vfioul off and Vbois on and Vbal on
-If Tbal on and Tbois then Vfioul off and Vbois on and Vbal on
-If Tbal on and Tbois off then Vfioul off and Vbois off and Vbal off


Resulting logic of the contactors (3 should suffice)

Vfioul = Tamb x no (Tbal) x no (Tbois)
Vbois = Tbois
Vbal = (Tamb x no (Tbois) x Tbal) + (no (Tamb) x Tbois)
Mamb = Tamb
Mbois = Tbois2 (Tbois-5 ° for example)

That's it, it's rectified!

[turbozender]

AH YES c not bad

the problem is that it completely neutralizes the thermosyphon between wood and balloon in case of power failure

[Philippe Schutt]

not if the valves are open at the time of the cut and the pipes big enough

[Philippe Schutt]

in passing I see that the attributes "crossed out" have disappeared during the copy and paste, the logic is false. I rectify.

Hi turbo,
