The use of natural gas is the most economical way of heating a wooden house. Fuel is among all the other alternatives is cheapness, and boilers it is the ultimate ease of operation. But how to arrange heating private houses without gas, it is not always a gas pipelines. What are the alternatives to this fuel, which option is the best?
The ways of the organization of heating in the cottage
Most frequently encountered in the domestic country houses, heating homes is water. As the heat carrier, it uses the water heated in the boiler or furnace. After heating it with batteries and pipes gives off heat to the rooms, creating a comfortable environment.
Heating system depending on the scheme of connection of heating devices are divided into:
- One-trumpet – serial connection of radiators, according to which the coolant is supplied and removed from the device through one pipe;
- Twin-tube with supply and return lines and the sequential scheme of connection of devices to the pipes where the coolant comes into the device to a pipe, and plays the other.
Both types of heating systems come with a top and bottom type wiring. The first option involves the construction of a feed pipe above the location of the coolant receiving devices, and second, respectively, below.
Location of tubes relative to heating devices may be vertical and horizontal, whereby the heating system adopts the same name the technical term. The first type is used mainly in multi-storey buildings or in single-storey cottages with attic, within which is possible to install a surge tank and laying of pipeline for supply of heat carrier on a separate thread in each device.
Horizontal heating circuit build in the small area of private buildings. The reason for lack of productivity, and limitations on the length of the network cannot length to be more than 30 meters.
Attaching the risers to the radiators is performed by unilateral or bilateral scheme, i.e. with the connection of pipes with one or two sides. If vertical one-pipe system connection batteries are on the one hand, it is called circuit overturned circulation. The latter is not recommended for systems with steel or cast-iron appliances.
The main elements of a typical heating system in a private country house include: boiler, radiators and pipelines of the heat supply By type of water circulation in the pipes of the heating system are of two types:
The natural – mean drift of the coolant through the laws of physics. Forced – suggesting the presence of a circulating pump to create circulation of media of thermal energy from the boiler to the devices, and after cooling in the reverse direction. The first option is easier the second in the design and installation. But the heat in the natural system cannot be automatic control, coolant it moves through the pipes due to gravity and the density difference of cold and heated water. But unlike the compulsory option, it is non-volatile.
When the power goes out heating system with natural circulation of water will continue to function properly if the main unit is non-volatile boiler. Pump, which requires power from an outlet in it either.
However, the gravitational pressure has its limits. Power of heating with natural circulation is just not enough for delivery of the coolant in the branched circuits. Sometimes it is not enough to supply the hot water required for heating temperature when the distance between the radiator and the boiler is 25 m, if the pipeline is made of a material with a high hydraulic resistance: steel or cast iron.
If the wooden house has a small area, then it is enough for the natural system. However, the large two to three storey cottage requires a more powerful variant with a pump, which will pump hot water to all remote from the boiler rooms on all floors.
In addition to the use of gas coolant can be heated by electricity or the combustion of other fuels. Also independent heating in private house, where there is no connection to the main pipeline with gas, often organized with the help of heaters, infrared heaters and heat pumps.
The choice of a particular method of the device of the heating system depends on many factors. Here, the climate region you live in, the quality of insulation of the home and the availability of a particular type of fuel.
Air heating is a good substitute for water, but because of the complexity of the calculations and design of it in our country rarely used the heating Circuits with circulating them with steam and hot air are arranged in the identical manner.
Of special note is to mention the system "warm floor", which is a network of pipes with circulating coolant under the floor. The main advantage of this option – as a result of receipt of heat from below the air in the room warms up to the optimal level of human growth, and not somewhere on the ceiling.
Alternative gas: the choice of boiler water heating
Natural gas is not the only type of fuel for Autonomous heating systems. As fuel in the boilers also burn solid or liquid fuel. Possible use for heating water electricity. Somebody prefers traditional stoves wood or coal, and who prefer the clean electricity. But it is worth remembering that in case of failures on networks the use of electric boilers will be zero.Option # 1: Solid fuel
Solid fuel stoves and their more modern counterparts boilers – the oldest and most popular method of heating private houses in areas without gas. It can be as traditional Russian stove and modern boiler equipment industrial manufacturing of various automatic equipment.
Ordinary solid fuel furnace is not too effective, better to take a more productive and efficient pyrolysis boilers long burning as a solid fuel is used:
- straw briquettes;
- wood pellets.
Such equipment is cheap and simple to operate. Fuel also is not very expensive. However, as a result of combustion formed fairly large amounts of ash, which need to constantly get rid of. Plus you have to visually monitor the operation of such equipment, that takes a lot of time.
On the one hand, the cheapness of fuel, and the other is regular cleaning of the firebox and the chimney. A unique solution "for" or "against" not here. But in a situation of living near coal deposits or near a forest, the choice in favor of solid-fuel boilers or furnaces for many obvious and often the only possible one.
As an option solid-fuel Assembly can safely be regarded a fireplace, although there exists a strong opinion about his poor performance. However, the fireplace with the right device is not only a decorative element of the interior, but also a good alternative to gas boilers. And he is absolutely non-volatile, which eliminates the interruption of heating in case of any problem on the grid.
Traditional fireplace means of the air heating only room where it is located, but nothing prevents to bring to it the pipe for heating the coolant most of the fireplaces are arranged in such a way that it is able to heat only one room. However, the standard chimney design can be supplemented by a coil around the chimney which will heat water for radiator heating system. And you can immediately warm the air to separate the rooms using ducts with adjustable dampers.
Fireplace heating is highly inert. To heat a private house requires a lot of time. The best option is to heat the fireplace constantly. However, wood in this case will need a lot. But all these minor inconveniences more than cover the opportunity to observe the combustion process of the wood and aesthetics of their own home.
A fireplace can be used as a boiler heating the heat medium for steam, air and water heating networksOption # 2: Liquid fuel
efficiency fuel oil (diesel) boilers differ very little from the gas counterparts. However, they are larger and heavy. For their installation requires a separate non-residential premises. Install them in the cottage under the stairs or in the kitchen is strictly prohibited.
The combustion of vegetable oils and oil products generate significant amounts of harmful emissions. Boiler for these plants must be equipped with high-quality ventilation system and chimney. Plus, incorrect installation and use they can start to smoke.
Two major drawbacks of liquid-fuel boilers – high cost of fuel and the need to comply with strict safety requirements For heating of private wooden houses, the following types of liquid fuel:
Kerosene. Diesel fuel. Testing of petroleum products. Oil. Biofuels from vegetable oils. Because of its specific odor and a high probability of ignition to store such fuel is recommended on the outside of the cottage. But in the winter in the street of the liquid freeze so we have for this quadcopter to make a separate heated room or make it preheat. And this is an additional and significant expenses.
Among the advantages of using liquid-fuel equipment for heating, it is worth noting the high efficiency, no need for registration of allowing documents for installation and Autonomous operation. However, the high price of fuel getting all these advantages. To arrange for heating of a wooden house without gas with diesel boiler is only in cases where there is no alternative, and she's not even expected in the future.Option # 3: Electricity
Electric boilers do not require a chimney. They are safe and have compact sizes. The heating fluid inside them comes at the expense of PETN. To use the boilers as both primary and secondary source of thermal energy. They are easy to use and effective, but heating them is pretty expensive.
Cost of heating boilers for electricity is comparable to gas models, but require less maintenance and more secure If the power supply in the village are not encouraging constant voltage, then you can choose a boiler for heating a private wooden house is risky. At some point, you can stay at a time without lighting and heating system. The only option in this case is a standby diesel generator.
Not always allocated energy capacity is enough for full heating of the cottage. And pulling the additional electricity lines will result in serious waste of money. The installation and the heating equipment is relatively cheap, but the last consumes electricity a lot. If you plan in a private house without gas heating equip with electric boiler, it is necessary in advance to prepare for a serious increase in your phone bill.How else could I heat a wooden house
To create comfortable conditions in the rooms of the cottage you can also use other means of heating. The new Autonomous heat now a lot. Some of them are expensive, but highly effective. And others suggested the use of alternative energy sources.Options infrared heating
the Main feature of the IR heat sources are heating not the air but objects and surfaces in a heated room. Already from the heated furniture, walls and floor heat is transferred to air masses in the room. As a result, when the lowest cost of electricity can create in the home to maximize comfort.
Electric heaters with infrared radiation are sold in the form:
- hanging panels in the buildings of various shapes;
- film devices for mounting on ceiling or floor;
- outdoor models (a La a conventional radiator).
There are IR heaters in automatic mode. It is sufficient to include them in the socket and set to desired temperature. Installation of wall and ceiling models are very simple, in the housing or on the tape includes all necessary fasteners. Complexity can only cause the installation of "warm floor infrared". But strict adherence to the instructions, everything is simple.
Film heaters under the ceiling is an excellent alternative to gas boilers: economical, does not burn oxygen in the room and completely safe from the point of view of the emergence of Pozarevac heaters allow to quickly create reliable and efficient heating system in any private house, where there is no gas. When compared with heating boiler they provide savings of 30-40%. Moreover, the heating of the rooms is much faster, almost instantly.
Infrared heaters can be used as a primary heat source or Supplement other heating system of the cottage. The diversity of the lineup gives you the opportunity to fit them into any interior, and, if necessary, to quickly increase heat output.
Among the negative aspects of the IR heaters static electricity, contributing to the attraction of dust, and considerable initial capital investment. With statics, especially anything to do will fail, and the cost of equipment is always worthwhile due to the low consumption of electricity.Heat pumps as a useful Supplement
Among the alternatives to gas for heating of wooden houses stand the heat pumps, extracting it from the entities of the environment. Structurally and technically, it is a conditioning to the contrary. Heat pump not only cools the air and heats it. And for heat energy it generates through judicious use of free natural resources and phenomena.
Heating based on heat pump for private houses without gas – this is the maximum savings on energy. But in our latitudes this type of heating can only serve as a Supplement to the main heating network the Disadvantage of heat pumps is their dependence on the voltage at the outlet. Without a constant supply they will not work. Plus, when severe frosts sharply reduced their effectiveness. In warm regions with winter temperatures around zero, the returns are excellent, but in Siberian conditions they are of little use.
The warmth with lower capacity heat pumps can collect from:
- outdoor air;
- of the earth by means of wells or pipe systems in the ground;
- water (any nearby pond or wells).
The heat pumps are all good. However, for a “free” energy have to pay a lot buying expensive equipment. For larger homes the cost can exceed one million rubles.Solar energy and wind turbines
Another option of “green” energy – solar panels and collectors. First generate electricity, and the second with the help of the sun's rays heat the coolant to supply in-house heating system. No gas is not required for operation, only need a constant wind and cloudless weather.
In the future, electricity and ground source heat pumps can be used for heating private houses by devices of the heating system with radiators and various electric heaters. Solar systems is a generators of electric and thermal energy. A heating of the room due to the various heating devices that connect to these generating devices.
Alternative energy requires significant investment at the stage of purchasing equipment, but then – no spending on fossil energy To turn wind generators convert into electricity for wind energy. And then to the power supply connect the heaters.
The main disadvantage of all these clean energy sources is that they depend on external factors. Cloudy weather and calm nullify their effectiveness. As a secondary source they are a sufficient way of heating private houses without gas, but to build the entire heating system just for them is not necessary.What kind of heating is the most economical
From the point of view of fuel costs the most cost-effective after gas main is an option with the wood. Cheaper fuel for boilers, furnaces and fireplaces are hard to find. Then there is coal, then electricity and diesel. In the case of alternative energy, the expenditure under this item is generally zero or minimal. However, we should not forget about the cost of thermal units for heat generation.
The cheapest in initial cost is heating with electricity, the equipment for such heating system is the most affordable of the totality of the cost to heat the house without gas it is cheaper electricity. But this only applies to houses with good insulation, as well as situations where the capacity of existing networks allow you to connect the heating equipment. In other situations it is better to opt for a more traditional solid fuel furnaces or boilers. published
