Methods of organizing heating in a cottage
The most common in domestic country houses, an autonomous heating system for the home is water. As a heat carrier, it uses water heated in a boiler or furnace. After heating it with the help of batteries and pipes gives off heat to the rooms, creating comfortable conditions in them.
Heating systems, depending on the connection diagram of heating devices, are divided into:
- Single tube - with a serial connection of radiators, according to which the coolant is supplied and removed from the device using one pipe;
- Double pipe - with a supply and return lines and a serial circuit for connecting devices to pipes, according to which the coolant is delivered to the device with one pipe, and the other is removed.
Both types of heating systems are available with upper and lower type of wiring. The first option provides for laying the supply pipe above the location of the devices receiving the coolant, the second, respectively, below.
The location of the pipes relative to the heating devices can be vertical and horizontal, on the basis of which the heating system adopts the same technical term.
The first type is used mainly in multi-storey buildings or in single-storey cottages with an attic, within which it is possible to install an expansion tank and lay a pipeline for supplying a coolant in a separate branch to each device.
A horizontal heating circuit is built in small-sized private buildings. The reason is the lack of performance and length restrictions - the network cannot be longer than 30 linear meters in length.
The risers are connected to the radiators according to a one-sided or two-sided circuit, i.e. with connecting pipes from one or two sides. If the batteries are connected on the one hand in a vertical single-tube system, then it is called an overturned circuit. The latter variety is not recommended for systems with steel or cast-iron appliances.
According to the type of water circulation in the pipes, heating systems are of two types:
- Natural - mean gravity of the coolant due to the laws of physics.
- Forced - suggest the presence of a circulation pump to create a circuit of the carrier of thermal energy from the boiler to the devices, and after cooling in the opposite direction.
The first option is simpler than the second in design and installation. But the heat supply in the natural system does not lend itself to automatic regulation, the coolant in it moves through the pipes due to gravity and the difference in densities of cold and heated water. But unlike the forced option, it is non-volatile.
When the power supply is turned off, the heating system with natural water circulation will continue to function properly if its main unit is a non-volatile boiler. There is no pump in it that needs power from an outlet.
However, gravitational pressure has its limits. The heating power with natural circulation is simply not enough to supply the coolant to the branched circuits.
Sometimes it is not enough to supply heated water with the temperature required for heating when the distance between the radiator and the boiler is 25 m, if the pipeline is made of a material with high hydraulic resistance: steel or cast iron.
If a wooden house has a small area, then the natural system is quite enough for it. However, a large cottage with two or three floors requires a more powerful version with a pump that will pump hot water to all rooms remote from the boiler on all floors.
In addition to using gas, the coolant can be heated by electricity or by burning other types of fuel. Also autonomous heating in a private house, where there is no connection to the gas main, it is often organized using convectors, infrared heaters and heat pumps.
The choice of a specific heating device arrangement depends on many factors. The climate of the region of residence, the quality of the insulation of the home, as well as the availability of one or another type of fuel are important here.
Heating circuits with steam circulating through them and heated air are arranged according to identical principles.
Of special note is the “warm floor” system, which is a network of pipes with circulating coolant under the floor covering. The main advantage of this option is that as a result of heat from below, the air in the room warms up optimally at the level of human growth, and not somewhere under the ceiling.
Alternative to gas: choosing a boiler for water heating
Natural gas is far from the only fuel for autonomous heating systems. Solid or liquid fuels are also burned as fuel in boilers.
It is also possible to use electricity for heating water. Someone prefers traditional stoves for wood or coal, while someone prefers pure electricity. But it is worth remembering that in case of interruptions in the networks, there will be zero sense from electric boilers.
Option # 1: Solid Fuel
Solid fuel stoves and their more modern counterparts, boilers are the oldest and most popular way of heating private houses in areas without gas. It could be like traditional russian stovesboth modern boiler equipment industrial production with various automation.
As solid fuel are used:
- briquettes from straw;
- wood pellets.
Such equipment is cheap and easy to operate. Fuel is also not very expensive. However, as a result of its burning, sufficiently large volumes of ash are formed, which must be constantly disposed of. Plus, you have to visually monitor the operation of such equipment, which takes a lot of time.
On the one hand, cheap fuel, and on the other, regular cleaning of the furnace and chimneys.There is no unequivocal decision for or against. But in a situation of living near coal deposits or near a forest, the choice in favor of solid fuel boilers or stoves is obvious to many, and often the only possible one.
As a variant of a solid fuel unit, you can safely consider a fireplace, although there is a steady opinion about its low efficiency. However, a fireplace with the right arrangement is not only a decorative element of the interior, but also a good alternative to gas boilers. Moreover, it is completely non-volatile, which eliminates interruptions in heating for any problems on the power grid.
Most fireplaces are designed in such a way that they can heat only one room. However, the standard fireplace design can be supplemented with a coil around the chimney, which will heat the water for the radiators of the heating system. And you can immediately dissolve warm air in rooms using ducts with adjustable dampers.
Fireplace heating is very inert. It takes a long time for them to warm up a private house. The best option is to constantly heat the fireplace. However, firewood in this case will need a lot. But all these minor inconveniences more than overlap with the ability to observe the burning process of logs and the aesthetics of their own hearth.
Option # 2: Liquid Fuel
In terms of efficiency, liquid-fuel (diesel) boilers differ little from gas counterparts. However, they are more dimensional and heavy. For their installation requires a separate non-residential premises. Installing them in a cottage under the stairs or in the kitchen is strictly prohibited.
The combustion of vegetable oils and petroleum products produces significant amounts of harmful emissions. The boiler room for these installations should be equipped with high-quality ventilation and a flue system. Plus, with improper installation and operation, they can begin to smoke.
The following types of liquid fuel are used to heat private wooden houses:
- Diesel fuel.
- Fuel and lubricants testing.
- Fuel oil.
- Biofuel from vegetable oils.
Due to the specific smell and high probability of ignition, it is recommended to store such fuel outside the cottage. But in winter, liquids freeze on the street, so you will have to make a separate heated room for such fuel or organize its pre-heating. And these are additional and significant expenses.
Among the benefits of using liquid fuel equipment for heating, it is worth noting the high efficiency, the absence of the need for registration of permits for installation and the autonomy of the work.
However, the high price of fuel interrupts all these advantages. To arrange heating a wooden house without gas using a diesel boiler is only in cases where there is no other alternative, and it is not even foreseen in the future.
Option # 3: Electricity
Electric boilers do not require a chimney. They are safe and compact in size. Heating of the coolant inside them occurs due to the heater. Electric boilers can be used as both the main and additional source of thermal energy. They are convenient to operate and efficient, but heating with them is quite expensive.
If the electricity networks in the village are not encouraged by the constant voltage, then choose electric boiler for heating own wooden house is risky. At some point, you can be left without lighting and a heating system at the same time. The only option for this case is a backup diesel generator.
The capacities not always allocated by the power engineers are enough to fully heat the cottage. And the extension of an additional power supply line will result in serious waste of money.
Installation and heating electrical equipment are relatively cheap, but the latter consumes a lot of electricity. If you plan to equip heating in a private house without gas with an electric boiler, then you should prepare in advance for a serious increase in light bills.

How else can you heat a wooden house?
To create comfortable conditions in the rooms of the cottage, you can use other methods of heating. There are many new products on the market of autonomous heat engineering. Some of them have a high price, but have high efficiency. And others suggest the use of alternative energy sources.
Infrared Heating Options
The main feature of IR heat sources is the heating not of air, but of objects and surfaces in a heated room. Already from heated furniture, walls and floors, heat is transferred to the air masses in the room. As a result, with minimal energy consumption, it is possible to create the most comfortable conditions in the home.
Electric heaters with infrared radiation are sold in the form of:
- hanging panels in cases of various shapes;
- film devices for mounting on the ceiling or floor;
- floor models (a la ordinary radiator).
Function IR heaters in automatic mode. Just plug them into a power outlet and adjust to the desired temperature.
Installation of wall and ceiling models is extremely simple, in the case or on a film all necessary fastenings are provided. Difficulties can only cause the installation of "warm infrared floor." But with strict adherence to the instructions, everything is done elementarily.
IR heaters allow you to quickly create a reliable and efficient heating system in any private house where there is no gas. When compared with a heating electric boiler, they save 30–40%. Moreover, the heating of the rooms is an order of magnitude faster, almost instantly.
Infrared heating devices can be used as the main source of heat or complement other heating systems of the cottage. The variety of the model range makes it possible to fit them into any interior, and, if necessary, quickly increase thermal power.
Among the negative aspects of IR electric heaters are static electricity, which contributes to the attraction of dust, and considerable initial investment.Nothing special can be done with statics, and equipment costs always pay off due to low power consumption.
Heat pumps as a useful addition
Among the alternatives to gas, when heating a wooden house, heat pumps, extracting it from the environment, stand apart. Structurally and technically, this air conditioner is vice versa.
Only the heat pump does not cool the air, but heats it. Moreover, he generates all the necessary thermal energy due to the wise use of free natural resources and phenomena.
Disadvantage heat pumps lies in their dependence on the presence of voltage in the outlet. Without constant power supply they will not work. Plus, in severe frosts, their effectiveness decreases sharply. In warm regions with winter temperatures around zero, the returns on them are excellent, but in Siberian conditions they are of little use.
Heat with low potential heat pumps can collect from:
- street air;
- land through wells or pipe systems in the ground;
- water (any nearby body of water or wells).
Heat pumps are good for everyone. However, you have to pay a lot for “free” energy by purchasing expensive equipment. For a large house, costs can exceed a million rubles.
Solar Power and Windmills
Another option for green energy is solar panels and collectors. The former generate electricity, and the latter, using the rays of the sun, heat the coolant for supply to the home heating system. They do not need any gas for work, they need only a constant wind and cloudless weather.
In the future, electricity and a heated coolant can be used to heat a private house by installing a heating system in it with radiators and various electric heaters.
Solar systems are generators of electric and thermal energy.The rooms themselves are heated thanks to a variety of heating devices that are connected to these generating devices.
In turn, wind generators convert wind energy into electricity. And then heaters are connected to the power supply.
The main disadvantage of all these clean energy sources is that they depend on external factors. Cloudy weather and calm nullify their effectiveness. As an additional source, they are a very suitable option for heating a private house without gas, but to build the entire heating system only is not worth it.
The most economical heating option
From the point of view of fuel costs, the most economical option after main gas is the option with wood. It is difficult to find cheaper fuel for boilers, stoves and fireplaces.
Then comes coal, and then electricity and diesel. In the case of alternative energy, the costs of this article are generally zero or minimal. However, do not forget about the cost of heat engineering units for heat generation.
In the aggregate of all costs, heating a house without gas is cheaper than electricity. But this applies only to cottages with good insulation, as well as situations where the power of existing networks allow you to connect heating electrical equipment. In other situations, it is better to opt for more traditional solid fuel stoves or boilers.
