Build/plaster tiled stove

[deklerkk]

I have 3 large and well-functioning tiled stoves. Good draft in good anthill, etc.

BUT

In some places, the tiles are starting to show signs, even if small so far, of needing to be reset.

This is a problem that I understand affects all stoves sooner or later, correct?

Tiled stoves are a good heat source if you read up on them, but they are fragile and need repairs/rebuilding, etc. They are sensitive to being fired hard, etc.

Has anyone repaired or plastered it instead when the tiles started to give way? Fix what is needed in it, then rebuild.
I'm thinking of removing the tiles. Then simply plastering them with, for example, a few centimeters of fireproof or other suitable mortar instead of tiles.

Wouldn't this be much more durable?

What you are describing is a rörspis also known as a "poor man's kakelugn". Has no advantages as far as I know. https://sv.wikipedia.org/wiki/Rörspis Regardless of what you choose, it must be built with kakelugnslera otherwise the construction will crack.

What you are describing is a chimney stove, also called a "poor man's tile stove." It has no advantages as far as I know. [link]
Regardless of what you choose, it must be built with tile stove clay, otherwise the construction will crack.

Well, there are only mortars that remain at a bit over 1000c. A chimney stove is essentially a tile stove in function.
I'm thinking more of fireproof mortar and something that holds the colossus together.

Hello,
Small cracks in the tiles are not what causes a tiled stove to need resetting. Instead, it's when the inner masonry gives way, the bricks in the inner channels are what get replaced when a tiled stove is reset, the tiles, even with cracks, can be reused.

Well, there are only mortars that keep just above 1000c. A chimney stove is essentially a tiled stove in function. I'm thinking more about refractory mortar and something that holds the structure together.

I don't understand what you mean. The tiles are part of the flue channel's construction, not just decoration. I understood that you are thinking of a fireplace built like a tiled stove with plastered bricks instead of tiles, essentially a chimney stove. Or are you thinking of completely replacing the tiles with mortar? In that case, I'm convinced you'll fail.

Tiles hold sand and cracked mortar in place.
The same function as if you had built with refractory mortar

Good luck! Looking forward to the follow-up.

A lot of exciting and fun reading at Kanerva.

Unfortunately, one can only draw one conclusion: kakelugnar are beautiful, but extremely delicate and often break.

I have lived with tiled stoves for a large part of my life and never had one that needed relining. They are not particularly fragile if you know how to fire them, and I would say they are very durable.
There are two parts to a tiled stove, the stove itself and the tiles; you reline the stove and keep the tiles, maybe every 20-40 years depending on how much you use it, and it's not insanely expensive either. It's usually the tiles that are expensive for an older stove. So it's a good investment and a very good heat source.
If you have a good stove, you light it morning and evening all winter and it should then be constantly warm throughout the day.

It was exciting reading. But the theories on how a tiled stove should be fired seem like a way to avoid repairing substandard deliveries.

Tiled stoves fired according to Kanerva's instructions probably last longer, but they hardly fulfill their function. I.e. as a good heat source.

Tiled stoves that are fired according to Kanerva's instructions surely last longer, but they hardly serve their function. I.e., as a good heat source.

It seems like you have burned or severely mistreated a stove and now want confirmation that you haven't done anything wrong.

You can destroy anything with fire, and you have to be very uninformed if you burn out a tiled stove, just as you can burn out a cast iron stove or anything else.

These are not theories; a tiled stove works in a certain way, for hundreds of years people have been using these masterpieces, and they still do. Durability is also fantastic.

A tiled stove is a heat source that warms around the clock, which you fire moderately once or twice a day. It is not a stove where you throw in logs and fire for the moment.

I don't completely agree with you in your response to the South African.

You can burn relatively heavily in a masonry stove. However, running it at full throttle and with an open damper for an extended period while feeding in wood is, of course, not recommended.

It's not as easy as people in various threads seem to think, to burn a brick oven to pieces.

Then it's challenging to get maximum efficiency out of every liter of wood. It requires some practice and experimentation.
Each stove and chimney functions differently.

You have a point. A kakelugn that can't be fired in the morning and evening is a bad method.
I have been firing for at least 10 years, morning and evening for 6 months a year. They haven't even loosened the clay plaster on the inside.

KANERVAS kakelugnar should be fired once a day. Then emptied of embers and closed.
Not a chance in He**** that firing for three hours can keep the oven warm for 24 H.
Lukewarm or room temperature maybe..

Do you have to be a master to state That

- the less you burn, the less wear.
- the weaker you burn, the less wear.
- if you interrupt the heating, the oven is better off?

Rather simple and logical reasoning. Like all things, if they are not used, they do not wear out. (General reasoning)

It's impossible to get any real effect if you burn like Kanerva.
A tiled stove for 100k+ must of course, and should withstand being burned 2 times a day, at least 120 minutes each time. Say, 5 hours a day.
