In this article we will consider Alternative heating of a private house when you find yourself without gas and electricity, how to make heating with your own hands ? More on this in this article. ...
Leading countries around the world have long been switching to alternative energy sources.
This brings a huge number of advantages, both for the owners themselves and for the environment. How to choose a suitable heating option for your home and not regret your choice?
Which system can fully provide the building with heat, and which one will only supplement the main one?
It is much more diverse and colorful than in a city apartment. Most people, realizing all the advantages of their own building, strive with all their might to change stuffy rooms for the freedom of a private plot.
And even if it will be only the summer season at the dacha, and not a permanent place of residence, the owners are trying to put all the best in the house. The supply of communications, centralized gas supply is not always available to independent buildings.
It is quite possible to completely replace the usual heating system with an alternative one. And there are a lot of examples around the world.
Unfortunately, this tendency is just beginning in our country. But given the steady rise in the price of conventional fuel, the spread of alternative heat sources will gain momentum.
The first thing you need to be prepared for is a significant investment at the initial stage.
It is necessary to perform a lot of calculations to provide sufficient energy for the whole house, and draw up a layout diagram of the nodes.
After purchasing the necessary equipment. In order to make the costs more democratic, the last point is better done by hand.
Let us consider separately the most common heating systems without gas.
Their action is based on the transfer of heat from a source with low potential in the living space.
Interesting! The elements of a heat pump system are very similar to those of the most common refrigerators. They have a heat exchanger, an evaporator, a compressor.
Freon, through the capillary hole, enters the evaporator and evaporates during a sharp change in pressure. The evaporator walls, heated by geothermal water, transfer thermal energy to the refrigerant.
The compressor, in turn, sucks in and compresses the refrigerant, thereby heats it up to 125 degrees, and then gives it to the condenser, directing the heat to the heating circuit.
The cooled refrigerant becomes liquid again. And the whole process is repeated from the beginning. Heat pumps cannot operate without electricity, so their use is only possible if there is an available power source.
There are the following types of heat pumps: soil-water, water-water, air-water, air-air.
Ground-water pumps are considered the most versatile alternative heating sources for buildings remote from the city.
They are less tied to climatic conditions.
Their versatility is due to the fact that even in permafrost zones at a depth of tens of meters, the soil temperature is above zero.
A device that allows to take heat from the ground is immersed in deep wells, several tens of meters, from which it is clear that the cost of the system is decent.
Drilling of only one such well is estimated at several thousand rubles. And several wells are required.
Tip! Slightly more economical is the option of a ground-water pump with a horizontal collector.
Another disadvantage of the system is the requirement of considerable installation space.
Water-to-water pumps are appropriate if there is running groundwater near the building. The price category of such systems is not high and the complexity of implementation is affordable. It only requires one immersion heat exchanger probe.
The immersion depth is from 10 to 15 meters.
Air-to-air pumps are the cheapest. An example of such equipment is a split system with a heating mode.
The air-to-water pumps operate on the basis of outdoor air. The heat exchanger in this case is a radiator with a sufficient fin area, which is blown by a fan.
The systems are also affordable and easy to install.
The disadvantage is that when the air temperature drops, heat transfer decreases.
The system is directly related to the intensity of sunlight. In the cold season and on cloudy days, the generated energy cannot cover the needs of a residential building in full.
However, solar panels are optimal as an additional source.
There are collectors with a vacuum tube and flat. In summer lighting conditions, the performance of both types will be equal. But in the winter time, the vacuum will dominate. Flat collectors can heat air up to 60 degrees. Vacuum - up to 90.
Also, both of them can be used to heat water.
Main the node is a wind generator (vertical or horizontal). Next come: blades, mast, weather vane, controller, batteries, inverter. The wind rotates the blades attached to the mast high above the ground.
The performance of the entire structure directly depends on the height.
The rotation of the blades acts on the rotor of the generator. It produces electricity, which is converted by the controller into direct current.
Electricity is stored in batteries. At the exit from the batteries, the current goes to the inverter, where it is converted into an alternating frequency of 50 Hz and a voltage of 220 W.
They are also called eco-heaters.
Their work is based on the transfer of heat in the form of infrared radiation to objects, and he already transfers it to the air. Such systems are capable of heating both the rooms of a residential building and people in the open air.
IR emitters provide significant savings in heating, due to directional heating of only the necessary segment of the space. Can be mounted on the wall, ceiling, installed on the floor.
A relatively new way of alternative heating.
The hydrogen boiler system works by reacting hydrogen with oxygen. The interaction of these two substances gives H2O molecules and heat of about 40 degrees. It is this that starts up to heat the air.
Huge choice, widespread use, ease of installation and modest dimensions speak in favor of the most ordinary electric boiler .
These include industrial waste:
This waste is tightly pressed into peculiar granules ( pellets ), which are intended for combustion in boilers.
The advantage of such pellets over ordinary wood is in the duration of burning and a large amount of released heat. One type of biofuel is biogas . It is formed by the decay of organic waste.
When choosing heating options , sometimes alternative heating of a private house will be more profitable.
That is, a heating system based on the use of wind, sun, water, heat from the bowels of the earth, biofuel and other sources.
There are also significant savings from the use of spontaneously renewable energy, although initially it does not seem so. Usually, such projects pay off in 4-7 years, then only the costs of maintaining the system remain.
