DIY rocket stoves

Thanks to the advanced level of modern technology, there are many different types of ovens that can easily perform their function effectively. In these rows the furnace—the rocket—occupies its place. It does not give way to its competitors. In addition, it is easily possible to do it yourself. DIY rocket stoves are real. This will be discussed in this article.

Operating principle of the rocket stove

In order to understand the instructions for constructing the device, you need to know how the unit works, as well as what the advantages and disadvantages are. The functionality is achieved by two methods, which are quite simple to understand.

The first is the free flow of fuel gases, which are directed through the channels. In this case, draft is created by the chimney, therefore, the structure does not require forced ventilation. This option is used in the simplest devices. The other is when, after burning wood, flue gases are burned. This method is most often used when long-term burning is required.

Variety of designs

Using a detailed analysis of each of the technologies, we will consider their activities.

Simple design

As for the device itself and its appearance, these are two small parts of the pipe that are connected to each other. The device is perfect for use in open spaces, namely for heating various liquids and preparing simple dishes. Heating occurs by collecting branches or wood chips. After their combustion, the results move into the chimney. The free circulation of heated air implements the principle of all actions.

Improved design

Due to the need for space heating, it is worth considering the named device, since the previous one operates exclusively for the manufacture of products. It is he who is able not only to cook, but also to maintain and maintain the desired temperature for a long time, thereby warming up the space. All this is done due to the second body - the heat exchanger.

Unlike the simplest unit, this one can be installed in the house, but the pipe must go outside. However, you should not leave it unattended, especially in residential buildings. It is recommended to define it in garages or small areas.

Modernization introduces another changes:

• Availability of insulation in the form of fire-resistant material.
• Installation of a duct to supply secondary air.
• Blowing occurs through a closed door.
• The outlet pipe is now located at the bottom of the furnace.

Rocket stove with a warm bed

Despite the fact that this economical type of design has significant dimensions and takes up a lot of space, it can be used instead of a bed or sofa. This provides the user with both a source of heat and an area for relaxation.

What is the “trick” of such a stove: long and interconnected channels pass through the distance from the stove itself, where the cooking channels are located, to the materials (usually clay, bricks or stones) from which the surface of the stove is laid. While the warm air mass follows this path, it cools over time and exits through a chimney located on the street, next to the house. To build super-efficient furnace models with your own hands, you need to prepare rocket drawings and remember the following nuances:

1. The firebox, which must be closed with a lid, is located in the lower part.
2. It, in turn, moves into the fire channel, which is located horizontally.
3. When using brick as a material for a bench, the channels can also be made from a similar product.
4. The combustion hole is vertical.

IMPORTANT! There should not be a huge amount of air, otherwise the gases that are initially released will cool down.

Advantages and disadvantages of the rocket stove

We can immediately say that such a device has a sufficient number of positive aspects. Let's look at some of them:

1. The most significant ones are simplicity and low cost. Its construction will not require a lot of costs or various funds. And even a master without experience in this field can handle the process.
2. In addition, a variety of types of fuel can be used: wood and solid.
3. Not afraid of long breaks.
4. The thermal output pleasantly surprises with its performance - it can reach from 10 to 18 kW.
5. It is allowed to add fuel during the combustion process.

Naturally, everything has its downsides. This device is no exception.

1. It is prohibited to use in baths due to the inability to provide heat for a short period of time.It is also undesirable to install it in residential buildings.
2. You can't leave him unattended. The device requires constant supervision.
