Good afternoon, my reader. A dacha is a temporary dwelling, where the owner usually visits only during the warm season. However, there is a desire or need to live there in winter. What is the best way to heat a summer cottage with an iron stove?

Pros and cons of an iron furnace
For a summer residence, the traditional brick structure is of little use: it is cumbersome, difficult to build, and expensive. It is best to use a metal ready-made oven. It is enough to connect it to the chimney - and it is ready for operation. But, oddly enough, the advantages of such a furnace can also be its disadvantages at the same time:
- Compactness. The metal stove is easy to install, easy to dismantle and take to the city, if necessary... and because of its compactness, it almost does not keep warm. Even if there is such a fire inside that the walls are red-hot, they are thin and do not work as a heat buffer.
- Fast heating. Modern designs of ovens with improved convection warm up the room quickly - they do not need to be heated for a day like a traditional Russian or Dutch oven. But this means that there is nothing to store heat either: with a high efficiency, such stoves immediately give off heat to the air, and if you make a fire hotter, you will get a faster, not longer, heating.
- Good traction. There is minimal or no risk of acne from ingesting excess CO during a night's sleep. But this also means that the fuel will not smolder for a long time in such a furnace and will quickly burn out.
How to improve efficiency
To sleep peacefully, without throwing up firewood every minute, you need a good heat capacity. How do I get it?
There are several ways:
- Facing the oven with bricks. There is a healthy grain in this method: a brick is good for its heat capacity. However, at best, a lousy brick oven with an iron core will come out, and the bricks themselves will work more as a heat insulator than a heat exchanger. However, the good thing about cladding is that it forms an insulator between the hot stove and the wooden structures of the country house. So it makes sense to lay out the foundation and "landing nest" about a third of the height of the stove itself.
- Iron water tank. And here the initial thought is sound: water is the most heat-absorbing substance on Earth, and, having accumulated heat, it will then give it back to the air in the room. But the problem is that the tank itself is too small. If you can afford to make a storage tank in the form of a tank over the stove, piping and radiators to heat the room, this will work great. But this is already a full-fledged water heating, which is too expensive for a summer residence.
- Iron container with sand. The principle is the same: the sand heats up, stores heat and, when the stove burns out, will gradually give off heat energy to the air. The problem is that in the end the structure will be too bulky, but minimally heat-intensive.
Why all methods don't work
In fact, it is impossible to increase the heat capacity of an iron stove. The thing is that two mutually exclusive qualities are required from a summer cottage winter stove:
- Warm-up speed provided by convection.
- Specific heat and ability to keep warm for a long time.
But the problem is that a stove that heats up the whole room in a matter of tens of minutes (you don't want to spend a day heating a summer house?) Won't hold heat in principle: the laws of physics forbid. And vice versa: a Russian or Dutch stove will cool for hours, delighting the owners with warmth - but it also takes a very long time to heat it.
What can be done realistically
In order not to throw up firewood at night, you just need to properly heat the stove. For this:
- Make a big fire to keep the room warm.
- Fill the combustion chamber with wood or briquettes for 2/3 of the volume.
- Limit the oxygen supply so that the wood smolders but not burns.
As a result, the stove will heat up for a long time, giving off heat all night.
IMPORTANT: Do not block the chimney! Adjust traction with the blower only! Carbon monoxide, CO, is tasteless, colorless, and odorless - but deadly.
