Is it possible to reduce costs for heating a private house? To solve this problem, efficient boilers are installed with a maximum efficiency factor of up to 100%, radiators are mounted with the optimal heat transfer value. But in addition to this, you can use alternative energy sources, thanks to which you can make free heating of a private house with your own hands with photos and videos. But first, consider their specifics.
Alternative Home Heating Methods
The main task when creating any heating systems is to efficiently use energy to transform it into heat, to maintain the temperature in the house. In addition to traditional solid fuels, liquid and gas, others can be used. These primarily include solar energy and the geothermal properties of our planet.
It should be noted that free heating of the house is conditional. In any case, electricity will be expended for the operation of the installation for converting solar energy or temperature difference in deep layers of the soil. In practice, you can do the following types of free home heating yourself:
- Solar collectors. They convert solar energy, which is transferred to the coolant. Can be used as a source of hot water in the summer;
- Geothermal installations. They work on the principle of increasing soil temperature with increasing depth. More effective than solar collectors, since they are practically independent of external weather conditions.
In each of them, electrical installations are used - pumps, compressors, etc. Therefore, the full extent of truly free-of-charge heating of the house with your own hands, a video about which will help organize such systems on your own, depends on the efficiency of a particular installation.
First you need to calculate the power of the future installation for heating. In this case, the dependence of efficiency on weather conditions and technical characteristics of the house should be taken into account.
Do-it-yourself solar collector for heating a private house
A solar heating system for a private house is a good alternative for organizing an additional source of heat. In order to make this type of heating for yourself free of charge, you need a solar collector.
The principle of operation of factory models is based on the transfer of thermal energy from the coolant to water through a heat exchanger. The circulation of fluid in the network of tubes occurs due to the temperature difference at the top and bottom points of the structure. As an additional device to increase efficiency, a pump can be included in the free heating of a private house on a solar collector.
In vacuum installations, heat from sunlight is transferred to a special gaseous mixture. This reduces the inertia indicator - water heating through the heat exchanger is much faster than for liquid models
The cost of ready-made models directly depends on their rated power, design features.
| Model | Characteristics | Cost, thousand rubles |
| Vacuum with frame | Only construction | From 62 |
| DHW manifold, 3600 l / day | Together with highways | From 180 |
| DHW + heating | Including storage tank | From 325 |
Given such a high cost - is it possible to make home heating free energy on its own? To do this, you need the following:
- Wooden frame. The optimal size is 2000 * 1500 m;
- Tubes made of transparent polymer - cross-linked polyethylene.They need fittings and adapters;
- Heat exchanger. Can be used from an old heating boiler. Best of all - from gas;
- Cumulative capacity.
Tubes are installed on the frame, and they should be located vertically. Using fittings and adapters, they form a serpentine contour. To reduce heat loss, the front part is protected by a sheet of transparent polycarbonate, which is then painted black. You can find more details about the technology for making free-of-charge home heating at home in the video material:
However, such projects for heating a private house for free are ineffective. The main disadvantage is the dependence on weather conditions.
The solar collector must be filled with antifreeze or gas. The impact of negative temperatures should not affect its state of aggregation.
Geothermal home heating
For the practical use of truly useful free home heating, the installation of geothermal systems is recommended. They are three circuits, each of which performs a specific function.
To make such a free heating at home only with your own hands is problematic. The catch can be the organization of the main components of the system:
- Outer contour. It should be located in the ground at a depth of at least 10 m. An alternative is to immerse the pipes in a nearby body of water. It is important that the temperature of the medium is 7-8 ° C higher than on the surface;
- Middle contour. In it, with the help of a heat exchanger, energy from heated water (at least 10-12 ° C) is transferred to the refrigerant. After compression in the compressor, its temperature rises to 65-70 ° C;
- Inner contour. For free do-it-yourself heating using a geothermal installation, you need to transfer the temperatures of the refrigerant to the water in the heating system. This function is performed by the second heat exchanger.
However, even at the design stage, they often face the problem of independently organizing free heating of a private house. First of all, in the installation of pipes of the external circuit. A preliminary calculation is made of the depth of the trunk, where the temperature will be optimal in the winter. The use of a reservoir as the main medium with elevated temperature is not always physically possible.
For free do-it-yourself heating with a water-to-ground heat pump, you must first check the freezing depth of the pond. Pipes should be 15-20 cm below this point.
Also, for heating the house with the help of free energy, you need to perform earthwork. Drilling vertical wells will require the services of a specialized company. And it seems that it is impossible to make heating a private house for free on your own without a project. The cost of a comprehensive service along with equipment averages 750-800 thousand rubles. But this figure can be significantly reduced if we make a competent distribution of funds when organizing free autonomous heating of a private house:
- The heat pump can be purchased independently. On average, it will generate 10 kW of thermal energy per 1 kW of consumed electric power. The cost of soil models is 290-300 thousand rubles. Pumps of the type "ground-to-ground" will cost more - from 340 thousand rubles;
- To calculate the duration of the outdoor main in the free heating of a private house, you can use the online calculator. But at the same time, the accuracy will be significantly lower than when ordering a paid geothermal installation project. Such documentation can cost 25-30 thousand rubles;
- Soil drilling can be entrusted to the company organizing autonomous water supply systems. They can install elements of free heating at home. Doing it yourself is problematic.
Everything else is done independently.An example of organizing free-of-charge heating of a frequent home with one's own hands is shown in the video:
For independent design and installation of free heating of a private house with your own hands, it is best to familiarize yourself with the photo and video materials. A good example will help assess the complexity of future work, and will also become the basis for organizing the entire process.
