Boiler or wood boiler installation

[Christophe]

Here is the 1st draft:


Not bad this Dia really!

Do you think that an anti-thermosiphon valve is necessary in my case? (everything is more or less on the same level)

[Christophe]

Isn't my diagram beautiful? No one has an opinion?

[toto65]

Very nice project. All my encouragement. A day does not necessarily have 24 hours.

[Christophe]

So you think there are no "big" mistakes or oversights in the diagram?

Can I start to break through the walls?

Hi Christopher!

Very beautiful diagram! Long live Dia!

So you think there are no "big" mistakes or oversights in the diagram?

Can I start to break through the walls?

Wait a minute, I took the time to read the whole subject, I looked, and finally understood your diagram ... well, almost.

The connection to the solar panel is not very clear (is the thing marked P on the drawing?), And the preheated water, where does it come from? From your huge water tank, or what?

Otherwise, I didn't quite understand why you put your safety valve on the "cold" return side of your boiler ...

For the rest, the regulations look coherent, however lack your management of the heated floors, in particular for the control in T °, ​​based on the T ° ext (probe) and at least one probe in the atmosphere of a piece.

In any case, you're not far from the truth, nice job of plumbing in perspective!

I am your answers ...

Uh there are no solar panels connected directly to this circuit. Yes, solar preheated water comes from the solar thermal buffer, this is the indication EPS. I see that I forgot the legend for the probe / sensor: P = pressure gauge and T = temperature but I think everyone will understand ...

Otherwise, I didn't quite understand why you put your safety valve on the "cold" return side of your boiler ...

Ah yes, little mistake can be? In fact it was to go in the "right direction" with respect to the circulator ...

For the rest, the regulations look coherent, however lack your management of the heated floors, in particular for the control in T °, ​​based on the T ° ext (probe) and at least one probe in the atmosphere of a piece.

The heating floor management circuit is already present and is downstream from this circuit, which is only a replacement for T °. I'll do the full diagram as soon as I find a moment (I know you're in a hurry ...)

In any case, you're not far from the truth, nice job of plumbing in perspective!

I am your answers ...

Ben in fact ke counts "everything" to do in a flexible network (high density crosslinked polyethylene) like that if there is a modification to do it will be much simpler. And given the current price of copper, it's not a luxury at all ... quite the contrary.

In addition, it allows the tubes to pass fairly easily through a wall to hide them (there is one).

As soon as I start, live photo report ...

[Christophe]

Well I changed my mind ...

I will connect (in addition to the buffer in the diagram above) directly the deom boiler to the central heating circuit (heated floors), on the hot side of the 4-way valve.

I say and show you when it's over

Heated floor, it seems to me, that one cannot go too high in temperature, for underfloor heating.
Have you thought about that?

[Christophe]

Yes but as there is already a 4-way mixing valve so it will be fine (Finally, I hope...)

[Christophe]

I have almost finished the final scheme (I hope).

I have a little headache, here are the 4 possible operating modes, 2 of which are thanks to the addition of the wood boiler:

a) DHW solar and / or heating (therefore without any other contribution)

b) DHW wood with solar preheating and / or heating without solar preheating

c) DHW wood with solar preheating and / or heating with solar preheating

d) Emergency operation: DHW oil and / or heating

+ mix between d) and other functions but not very interesting.

I wanted each mode of operation to be possible independently of the others, so we can choose which energy does what ... with the aim of using 0 fuel oil (this is the case for the moment but winter is not still arrived so I have to shake my ass to ride this Deom!)
