Hello,
I am looking for a used wood boiler. I went to see a 30 Solo Innova 2009KW. It is "clean", has no tar or oxidation. All the stones have been changed but the bottom one (where there is a lengthwise opening in the middle) is split in the extension of the opening.
The boiler did not work very well with new stones.
Can you tell me if this crack is serious or not (it is 1mm wide)?
Thank you for your comeback.
cordially
Cracked refractory stone wood boiler, is it serious?

Re: cracked stone wood boiler
It doesn't matter (there are also slits around the other parts), but you can always try sticking a bead of refractory cement on it if you're worried. Afterwards, I don't know if it lasts long, I've never used it.

Re: cracked stone wood boiler
It is not a "stone", but a molding in refractory materials which are subject to cracking due to expansion during heating. Normally, this is not worrying.

Re: Cracked refractory stone wood boiler, is it serious?
Well thank you for those answers.
But a silly question, when should these casts be changed? and why do they know?
Come on, let me have one last question! When I go to see the boilers, I pay attention to the refractory mouldings, the interior sheets, the cleanliness of the flue. But is there anything else I should look at?
Thank you for your valuable explanations!!
Good night

Particular attention should be paid to the condition of the interior sheet metal at the bottom of the hearth: it is common for condensation of acid vapors in the lower parts to attack the sheet metal and cause leaks...

Yes, the tendency to oxidation is a tangible fact over time. I stop this phenomenon with diluted citric acid without rinsing, it's like the Frameto for much cheaper and without danger.

Re: Cracked refractory stone wood boiler, is it serious?
we change this stone when a piece of about 2cm is missing.
Condensation:
This is an inverted flame boiler with the assistance of a fume extractor. The fire of such a boiler must not be smothered.
I adjust this type of fire to obtain a fairly white but not blue flame (primary/secondary air), the T° of the fumes around 250°, and the T° of the water around 80°.
unless it bistre in the extractor.
If you have thermostatic taps and heating control, you will need 2000L of buffer.
Here, and there no condensation and no bistre.
