Solar mounting ROTEX Sanicube 538?

[harley58]

Hi,
I just install a Solaris Sanicube rotex 538 / 16 / 0 and 5 panels to supplement my chappé boiler fuel, low temperature, with outdoor sensor and operating module.

Looking at the instructions for use and installation of the Solaris Sanicube rotex, I came across a paragraph (5.3.7) dealing on blocking the operation of the burner or other external device heat generation by means of a contact. I examined my setup and found that the liason between the Sanicube cable management module and the boiler was inexsistante.J'ai contacted my installer and the çi told me it was not necessary.

When do you think? Does anyone could give me further information or give me his experience on this subject
If this function exists, there are reasons

Here is a Sanicube documentation: https://www.econologie.com/rotex-sanicub ... -4072.html

thank you to all

Hi,
This topic also worried me, reads:

My question about the Forum:
""Hello,
The equipment was delivered (boiler, screws, rotex ball 5 the panels are laid on the roof, the elevator! Remains the hopper)
I searched and found the ÖkoFEN manuals (user and installer).
I plunged in to understand before the arrival of the installer and the technician (end of January). the forums help me well (TEM regulation).
I have a question perhaps silly:
The boiler and its regulation can manage solar (7 level) but the ball combined Rotex SSC 538 / 16 / 16 has its own Regul. The what is going to be used?
This ball should it be considered as a combined storage or as a storage tank?
At the 16 page of Regul. TEM TPO probe denoted probe p15 ball is drawn into the boiler ...
Sincerely.

Answer: Post 111927 from Forum:
as it is a drain-back solar system, I'm not sure it would be wise to do so by managing the boiler.
I'd rather let it manage alone. there against by a cable with dry contact failure to prevent the boiler from starting if the ball is hot enough. In my view, it duplicates the probe régu.l boiler is deported to the ball and sees that it is hot enough. so I do not cablerais this contact either.
has noted that the doc. solaris has air rather advocate the opposite; that is to say that the boiler does not probe for information about the temp. but the ball is the ball which informs by contact when the ball is hot.
we should still be able to return a boiler probe in the pocket of the balloon would be better (ECS probe TBO)

I think we manage it as a storage tank, not a buffer.
first of all, the okofen modulating boiler does not need a buffer and it should not be forgotten that a buffer is a palliative to the problem of non-modulating boilers such as wood-logs. accumulating the trawl to redistribute it later is not energetically ideal because there are losses. It is better to "manufacture" the heat on demand. In addition, this balloon is small. Even when used as a DHW tank, there is still the icing on the cake with the return heater which can, on occasion, add a few additional solar calories (if available)
by cons I do not understand the usefulness of 2eme exchanger in your version of 16 / 16 instead of 16 / 0 ???

for the TPO probe, when there is no buffer tank, this probe is placed on the top of the heating body and sees the boiler temperature. normal, therefore. ""


Until perhaps other answers enlighten you.
Kind regards.

JC

Manet you should mention the subject that you quote because it's hard to understand.

I did not know the system ROTEX (I found a .pdf) but in principle, what I had experienced with our wood boiler (ECS passes in the exchanger) and it does not work terrible ( ca see this page if you are interested: https://www.econologie.com/forums/photos-et- ... t4368.html ).

Obviously it was not designed for, but I ask myself the question anyway: do not you temperature variation with rotex?

A priori, the water should be warmer start right?

In their documentation Rotex Sanicube it is written:

Heat capacity available kWh / 24h: 1,4

What must be éronné because only one shower (L 50 30 to heat ° C in winter) is roughly 2 kWh (magnitude) ...

[harley58]

Good evening,

Thank you for these responses.
I would also mention another point that bothers me also is that my installer returns connect radiators on the output of the additional heating exchanger and not on the entry. Meme, it uses the most hot water tank in the boiler to produce and store hot water, but warmed directly Sanicube.

Thank you for all the answers that you could bring me

Hello,
Sorry, no communication specialist ..
I do not know how to cite the tropic.
Now I ask myself the problem for not being caught ..
Kind regards.

many questions with this rotex ball.

the "instant" DHW heating system: why not if the heat exchanges between the DHW coil and the "dead" water in the tank are sufficient to transfer the necessary heat.
actually, Christophe, the water that is already in the coil is warmer than that which comes after, but on installing Chaboum (which seems to me correct the hydraulic point of view) there is a thermostatic valve output that ensures mixture with cold network water to make a ECSA at constant temperature.

harley58,
there must be a connection between the boiler and the tank but it can be done in two ways:
- either the boiler is "basic" old style oil boiler and we use the famous contact of the Rotex regulator to force the burner to work as long as the water in the Rotex is not at temperature.
-either the boiler can manage a storage tank (which is the case with yours a priori) and deports the DHW temperature sensor of the boiler Rotex in the thermowell.
in this case, the boiler knows whether or not it is necessary to heat the flask.

for connection: the radiator must go back to the central blue entrance and the center red output (heated) should return to the boiler after getting connected with the blue out of the cylinder primary exchanger.



that the old ball of the boiler is no longer used is not critical in itself. he would see how it was hydraulically connected. I suppose it is not heated, suddenly? .

[Christophe]

OK for the valve, by cons I still do not understand the line of .pdf:

Heat capacity available kWh / 24h: 1,4

(1.4 kWh is really not much energy available for 24h)

[dirk pitt]

probably a translation error because lower, it is said that without heat, we can draw 220L to 40 ° with cold water 10 °. it must be within the capacity 7kwh.
I know however is the 1.4kwh / 24h, maybe the heat loss of the ball ??

[Christophe]

Oh yes, well done! Sacred translation error say so!

But 220L to 40 ° C with an elevation of 30 ° C it gives: * 220 4.18 30 * / = 3600 7.7 kWh.

In another subject ( https://www.econologie.com/forums/a-quelle-t ... t6544.html ) I do not remember who said that the "normalized" loss in 24 hours should be a maximum of 10% ... or 1.4 / 7.7 = nearly 20% there ...

Mystery, then!
