ᐅ Wood-burning stove "Iron Dog I" .... does anyone know it?

During my search for a "suitable" wood stove, a few options caught my attention. They are all small, as a larger stove would not be practical.

Brunner, Iron Dog 1
Jotul, F 602
Nordpeis, Orion
and Nordpeis, ME Wall

For the intended use, I like the "Iron Dog One" the most. However, I can’t find any reports worldwide from someone who actually owns one.

The chances might not be good, but I’ll give it a try:

Does anyone know it?

One reason for the prices of your selection is that these are without thermal storage stones and without cladding. Simply from a cost perspective, this means less material, while appearance is always a matter of personal taste. In several consultations, we were quickly advised against choosing pure steel stoves because they release their heat very quickly into the room and can easily cause overheating in new builds. That’s why we decided on a fairly massive stove. It has suited us well and proven effective. No issues with overheating, and the stones retain heat for about 12 hours after the fire has gone out. It also weighs 550 kg (1,213 lbs).

... or push it out through the chimney. It’s up to each person to decide which they prefer: long-lasting heat storage or quick heating and cooling.

meanwhile I have found "cheap" fireplace inserts.

🙂

Would you like to share which ones?
We still have to make that decision ourselves.

There are good-looking stoves available for under 1000.
Insert fireplaces – based on my research – cost at least 1000.
Here, inserts costing 5000 were mentioned... 😱
I didn’t find exact prices for the Kratki MBM 11, but they were all around 1500?
... but talking prices with me is basically pointless, because I never remember them properly and then get them mixed up... 🙄

The fact that cast iron stoves release heat quickly into the room doesn’t only have disadvantages.

The fact that more heat is stored in fireclay stoves also means that more of it likely escapes through the chimney, since it’s open in that direction.

Arguments can sound convincing while still being misleading... (don’t I know that from Corona too?)
That’s why I find experts important who don’t just deal with a topic briefly, but study it thoroughly over a long time.

I usually stick to specialists whom I consider trustworthy... completely subjective...

I don’t think so; the heat is absorbed by the firebricks and stored there, then slowly released into the surroundings.

In my old house’s fireplace, I had a firebrick insert, but for the casing I also used firebricks as a base structure and then covered them with the facing stones.

Where does the heat go?
This is – for me – a question that can be discussed extensively without arriving at a verifiable answer.

Undoubtedly, a large part of it escapes through the chimney.
A material that absorbs heat quickly also releases it quickly.
Cast iron, for example, does this faster than fireclay (refractory bricks).
Temperature differences are therefore transferred to the room more quickly by a cast iron stove than by one made of fireclay.
The fireclay stove retains heat longer and spreads the release over a longer period.
During this time, heat continuously escapes through the chimney.
The faster the heat is transferred into the room, the less can be lost through the chimney.

As far as I know, cast iron stoves can have a cast iron insert instead of fireclay.
This also stores heat and releases it quickly. The thickness of the material, of course, also makes a difference…

I don’t find the matter entirely clear.
I’m not claiming that cast iron is better than fireclay, just different – and not worse in every case.

In my opinion, the advantage of fireclay lies in the fact that it usually feels more comfortable when heat is released slowly and evenly.
The closer the stove is to the user, the more noticeable – and probably less comfortable – temperature fluctuations are.

How this affects fuel consumption (how much wood produces how much heat) and the cleanliness of the exhaust gases (higher temperature means less “dirt”?) can probably be measured more accurately than estimated theoretically.

… I just enjoy talking about it 😉

One reason for the invention of fireclay, I believe, was that it is cheaper than other refractory stones and can be easily shaped to fit in stoves. Originally, it had nothing to do with heat storage.
