Been a long time since I posted here, but started a new project on Croatia. Here are loads of old tile stoves, often not build all that well, and you can get them for grabs. Looking at the door, great to use with little changes of a bb rocket, I thought this was a cheap way to make a nice retrofit. The tiles would act like a stratification chaimber, after that the gasses will go through a short mass that is already here and was fitted before with a 100 mm 4 Inch J rocket dragonheater Peter van den Berg style.  Here it is difficult to get the right sizes for the floor channel, so I came out to the 115 mm as the sizes for the steel were available here.  This photo is just for show as the heatriser will get higher. The heatriser blast will miss the ceramic top by 2,3 Inch, 6,2 cm and I will put a steel plate on top of the gap, no tiles. Now, those tiles are meant to be able to stand some decent heat, but Satamax got me worried. He said that there might be a chance that the tiles would heat up too fast in the middle causing stress as when they are in the top of the stratification chaimber.  You see they have a thick rim, but the middle is just 3/4 Inch thick or 14 mm. Do I need to protect them from the heat of the heatriser? Like I need to fill them with a clay and woodash mix, or can I glue ceramic felt in them? Cheers Bart |

Hi Everybody.
What i was explaining to Bart, is that Peter few years back; was advising to line the inside of a brick bell, in the same kind of configuration. To avoid cracking of the joints.
We spoke quite a while, and i was saying, at least, to not use the top rounded tiles, and make his cooking plate bigger, and removable, jointed with superwool. So he can open the stove, if anything needs to be done.
If it was for me, i would fill those with cob. Or something similar.

nice idea. Those stoves have a decent efficiency as they extract a lot of heat but combustion efficiency has to be like a regular box stove (70%).
those tiles can handle heat and if joints crack I just fill them with clay/sand mortar.

Thanks Guys,
I think I will use the curved to tiles after all, as I am afraid that I will overheat the room in no-time when the top steel plate gets too big.
I can take them off and put on straight tiles later if I want.
Main question is those tiles, if they can stand the flash heat, the fast heating up.
I got screened clay ready to fill them up, if need to be.
Cheers Bart

those tiles should have been filled with chamotte plates (3,2 cm thick) and such mortar and clamped one another with a metal clamps.
Additional layer of 3,2 chamotte as another accumulation and airt tight layer is pretty advisable in case of those tiles.

I haven't seen the results on FB, but Bart started to fill the tiles with clay or mud. By the way, i find we haven't seen Peter for a while here. I hope he's all right. |

peterberg let us know you are live and kicking. Yes I am, thanks for asking. Busy with a project, I'll need to update some thread. |

Good to see you peterberg |

So in other words, these old tile stove tiles can't stand heat at all? I'm just saying how those stove were constructed. It used to be a channelled setup. The layer of the tiles filled with clay will hardly serve as air tight bell. We retrofited a few stoves like that (sized 3 tiles by 5) but with a chamotte plate inside the tails and additional layer of them glued with chammote mortar to that tailed surface. |

Sorry Satamax, With the online job, I haven't had much time to do anything. ![]()  I filled the tiles with a fireclay/perlite mix and that crimped more that I expected, so I had reform and at the end I filled the sides with fresh clay.  The wire holes I used for a pin, that keeps the clay tile fixed in the tiles stove tile.  The space for the mortar (sand, aluminium cement and lime) is almost 5 cm deep, so I thought that would be safe enough to be air tight. These are the lower tiles that I didn't fill. The top 2 layers will be filled, the 3rd layer of tiles with clay/perlite and the 4th layer of tiles with aluminium cement/perlite/sand mix as I don't have the time to wait for them to dry. |

bartjmeijer I don't see any pictures, do you have some? I'm just saying how those stove were constructed. It used to be a channelled setup.

We retrofited a few stoves like that (sized 3 tiles by 5) but with a chamotte plate inside the tails and additional layer of them glued with chammote mortar to that tailed surface. interesting I thought it is a straight swap since those tiles and joints could withstand over 400C in original setup.

Ah thanks,I used aluminium cement with some line and fine sand, so it should be fine
