How to arrange water heating in the country by yourself

As a rule, during the construction of country houses a stone wood-burning stove is installed. However, over time, the houses "overgrown" with extensions or it just turns out that the furnace is not enough to fully heat the house, as a result of which there is a need to install a water circuit. Therefore, in this article we will look at how in such cases to equip water heating in the country with their own hands.

General information

In order to equip water heating in the country, it is not necessary to acquire a boiler, because there is an oven that differs from the boiler only in the absence of a heat exchanger. Accordingly, for arranging water heating it is only necessary to add this missing element.

Of course, in addition to the stove with water heating, you will need pipes, radiators and some other heating elements. In general, to equip such a system under the power of every home master, as we will see below.

Heating arrangement

Heat exchanger

It is necessary to begin work with performance of the heat exchanger. This device is a metal structure, welded, usually from pipes.

This part is installed in the furnace or behind the furnace, at the very beginning of the chimney. The latter option is more preferable, as the efficiency of the furnace for the dacha with water heating in this case increases.

Most often for the manufacture of the heat exchanger used pipes of ordinary black steel, because of their low cost. However, the device will be much more durable, if for these purposes to use heat-resistant stainless steel. However, in this case, the price of the product will increase significantly.

The shape and size of the heat exchanger depends on the design of the furnace, and more precisely - the furnace. It can be a g-shaped or even a flat tank with a volume of 20-30 liters, a coil, a cylindrical tank, etc.

The only thing when designing this part is to take into account the following points:

• The greater the difference between input and output - the better.
• The efficiency of heating depends on the area of ​​the heat exchanger - the larger it is, the more power, respectively.
• The design should be designed so that it does not impede the loading of fuel and does not interfere with the combustion process.

Note! To install the heat exchanger you will need to partially disassemble the furnace. Perform this operation carefully to avoid problems during assembly.

It should be noted that correctly made heating furnaces for summer cottages with a water circuit are almost as effective as factory boilers.

Tip! As the heat exchanger, you can use a cast iron battery. True, to install it, the firebox must be of sufficiently large volume.

System arrangement

After installing the heat exchanger, we can assume that half the work is done. It remains only to complete the installation of the system itself. Since the disconnection of electricity in rural areas is not uncommon, but even a regularity, the best option is a gravitational system, i.e. with natural circulation of the heat carrier.

Tip! Pipes are best to use polypropylene, as they are of low cost and durability. The only thing for their installation will need a special soldering iron, which can be rented.

Before you do the heating, you should prepare a project. For natural circulation, a one-pipe circuit is used. In this case, the inputs and outputs of the radiators are connected to one pipe, respectively, all batteries are connected in series.

One-pipe water heating of the dacha implies the presence of a booster tank, which is connected to the heat exchanger and is located as high as possible.

In general, such a scheme is as follows:

• From the tank circuit goes down and passes through all the rooms of the structure. Moreover, the pipe should have a constant slope, which is necessary for the natural circulation of the coolant.
• Radiators are connected to the circuit in the places marked on the diagram.. It is desirable that each battery has a bypass and valves. This will allow you to adjust the level of heating radiators.
• Having walked around the house, the contour returns to the furnace and is connected to the heat exchanger inlet.

It must be said that such a scheme is ineffective in large houses, where it is more expedient to use a two-pipe system. However, in this case, you will need a circulation pump to provide the necessary pressure. In addition, the price of such heating will be higher, since it requires almost twice as many pipes.

The meaning of this scheme is that the radiator inlets are connected to one pipe, and the output - to another. In this connection can be made both sequentially and in parallel. This solution allows for uniform heating of the batteries.

Tip! If 40 parts of salt is added to 100 parts of water serving as a heat carrier, then its freezing temperature will drop to -20 degrees.

An essential element of the heating system is the expansion tank, which is designed to compensate for the thermal expansion of the coolant in the system. Typically, this element is installed near the circulation pump.

Here, in fact, the whole instruction on the arrangement of heating in a country house.

Conclusion

Arrange water heating to give their own hands is quite simple. The main thing in this case is to make a suitable heat exchanger and place it correctly. Otherwise, the work does not differ from the installation of a conventional heating system.
