Wood stove "Iron Dog I" .... who knows it?

A reason for the prices for your selection is the fact that they are without storage stones and without cladding. Now, purely from a price perspective, material is omitted there, and appearance is a matter of taste anyway. In several consultations, we were quickly advised against pure steel stoves because they release their heat very quickly into the room and can lead to overheating in new buildings. That’s why we chose a rather massive one. For us, it was just right and has proven itself. No problems with overheating and the stones retain heat well for 12 hours after the fire is out. It also weighs 550kg.

... or blow it out through the chimney. Everyone has to decide for themselves what they prefer. Storing heat for a long time or quickly in/out.

meanwhile have I found "cheap" fireplace inserts.

:)

Would you like to write which ones.
We still have to make the decision here too.

Good (looking) stoves are available that cost under 1000. Fireplace inserts - according to my research - at least 1000. Here, inserts were mentioned that cost 5000 ... :eek: I didn't find the Kratki MBM 11 precisely, but they were all around 1500? ... but talking prices with me is basically nonsense because I never remember them anyway and then get them mixed up ... :rolleyes: That cast iron stoves release heat quickly into the room does not have only disadvantages. That more heat accumulates in chamotte stoves probably also means that more of it goes out up the chimney because it is open there. Arguments can sound plausible and at the same time be misleading ... (don't I also know that from Corona?) That's why I find experts important who deal with a subject not just once but for a long time. I usually stick to the specialists I consider trustworthy ... completely subjective ...

I don't think so, the heat goes into the fireclay bricks and is stored there, then slowly released to the surroundings. I had a fireclay insert in the fireplace in the old house, but for the cladding I also used fireclay bricks as a basic framework and only then put the cladding stones on top.

Where does the heat go?
That is – for me – a question one can discuss well without getting a verifiable answer.

Undoubtedly, a large part goes out the chimney.
A material that absorbs heat quickly also releases it quickly.
Cast iron, for example, is faster than fireclay.
Temperature differences are therefore released into the room faster by a cast iron stove than by one with fireclay.
The fireclay stove holds heat "tighter" for longer and thus spreads out the release over a longer period.
And in that time, heat continuously slips out the chimney.
The faster the transfer to the room is, the less can disappear through the chimney.

As far as I know, cast iron stoves can have an insert made of cast iron instead of fireclay.
It also stores ... and releases quickly. The materialthickness naturally also makes a difference….

I don’t find the matter really clear-cut.
I don’t claim that cast iron is better than fireclay, but different – and not in every case worse.

In my estimation, the advantage of fireclay lies in the fact that it is usually more pleasant when the heat "comes" slowly and evenly.
The closer the stove is to the user, the more noticeable – and probably more unpleasant – temperature fluctuations are.

How this affects consumption (how much wood for how much heat) and the cleanliness of the exhaust (higher temperature means less "dirt"?) can presumably be measured better than theoretically assessed.

... I just like to babble ;)

One reason for the invention of fireclay was – I believe – that it (or he?) is cheaper than other refractory stones and can be easily worked into stoves. Originally, it had nothing to do with heat storage.
