How to make a heat exchanger with your own hands

Let's consider an example of calculating the power. First, you need to determine the power of the equipment that can provide heating of the room. For example, we will operate with 5 kW, capable of maintaining the microclimate.
The heat exchanger should be taken with a reserve. We accept its area of 1 square meter, capable of operating at a power of 10 kW.
Explanation. When making calculations, you need to take into account the proportion - 10 kW is equated to 1 square meter. To take into account all heat losses, the values are adjusted. The moj data takes the following form - 1 sq. m. = 10 kW - 3 kW.
Using this approach, you can achieve the desired room temperature by heating the stove once or twice.
To make the device yourself, you need to decide on its type.
Below are instructions for heat exchangers in a bathhouse for hot water of two types: near the chimney, inside the stove.
Heat exchanger in a sauna stove near the exhaust pipe
The simplest and most effective way is to use copper pipes. Here the diameter of the chimney is taken into account, relative to which the length of the pipes (up to 2 meters) with a diameter of about 10 mm should be taken. The smaller size of copper devices significantly increases the speed of boiling water in the pipes, and the movement of the liquid is limited. It is recommended to use 10 mm pipes.
Flared adapters are placed on both ends. Flaring is done with special devices. This procedure must be done carefully. A flat surface must be achieved to avoid leaks. Copper wire is "wound" around the chimney in the form of a push-in, the ends are connected to a water tank. The structure is ready.
