Today, the organization of heating a private house without gas and electricity is a very relevant issue.
The regular increase in the cost of these traditional energy sources leads to the search for alternative, more economical sources of heat.
And today, combined heating systems are increasingly used, using main sources of thermal energy and local ones.
There is a category of residential buildings in which alternative heating is the only possible option. These are houses located in areas remote from civilization, where there is no way to connect to a gas or electricity network. This group also includes some dacha cooperatives, in which it is customary to turn off the power supply in the winter.
Types of alternative heating
Today, several heating systems for a private house without gas and electricity are used — both traditional and innovative:
Heating of housing by means of a wood-burning stove has been practiced in Rus’ from time immemorial. Then they were used to heat small wooden huts, usually consisting of one common room.
With the beginning of the use of non-combustible building materials, for example, natural stone, brick, the heating scheme based on the European stove has improved significantly. A rough was created — a chimney-heat exchanger, which is a serpentine system of channels built in the wall.
Thus, it became possible to effectively heat two separate rooms, and the efficiency of the furnace increased significantly — hot smoke did not fly directly into the chimney. Today, such a heating scheme is used in many small summer cottages, hunting houses.
In the twentieth century, another improvement in stove heating took place. The furnace began to be equipped with a special tank in which the liquid coolant (in the simplest case, water) was heated, after which it circulated through the pipes, giving off the accumulated thermal energy through heating radiators. Now it has become possible to heat a multi-room house.
In the future, this scheme was more and more improved: expansion tanks began to be used to protect the system from overheating and destruction, circulation pumps that effectively supply the coolant to the upper floors of a multi-storey private house, and various electronics that control heating. But the last two elements already require a functioning electrical network, therefore, in areas where there is no electricity supply, they are practically not used.
To date, laying a furnace performed by representatives of a licensed construction company can cost about 70–1000 $. The services of a private trader can be much cheaper.
Operating costs for wood/coal heating depend on the cost of firewood in your area, the quality of the stove, the rough or heating system, the thermal insulation of the house, the area of glazing, outside temperature, wind strength and other factors.
If there is a lot of dead wood nearby, then the operating financial costs can be reduced to zero, only your skills in cutting trees and chopping firewood will be required.
Heating fuel boilers
They are an improved modification of the furnace. To date, heating a private house without gas and electricity can be carried out using the following boiler modifications:
- solid fuel;
- liquid fuel;
The following types of raw materials and products are used as solid fuels:
- pellets and others.
Solid fuel boilers are classified according to several criteria:
- Versatility. There are modifications that can run on any type of fuel and are designed to burn a specific energy resource. Universal boilers are much more expensive, less durable and efficient.
- Power. An indicator that determines the calorific value of boiler equipment, respectively, the maximum volume of the heated space.
- Energy dependence. Models are produced that do not require connection to the mains — with fully mechanical manual control and require low power consumption — modifications equipped with an auto-fuel system and control / protection electronics.
Oil boilers diesel fuel (solar oil) is used as a heat carrier. There are also volatile and non-volatile modifications. The former are safer to operate, since they are equipped with automatic parameter adjustment and protection circuits in emergency situations, but more expensive. The latter are cheaper, but require constant monitoring and manual adjustment.
Universal boilers can operate on several or even all energy sources — gas, diesel fuel, wood, pellets, electricity, coal.
The cost of boilers depends, first of all, on their performance. So, the price of the most low-power European-made solid fuel boiler, capable of heating a small house with an area of 50–60 square meters, starts at 100 dollars. Installation and connection of a boiler with a chimney will cost from 30 dollars, depending on the dimensions of the unit and the complexity of the work being done.
Operating costs, again, depend on the cost of the fuel used in your area or the availability of free resources.
In fact, this is the same European stove, only with the ability to admire the flame. They are more decorative than functional equipment, although modern models are able to heat a rather large room. Traditionally, wood is used as fuel.
Fireplaces come in two main varieties. The first one develops brickthe second, manufactured metal, purchased as a set. The cost of brick fireplaces depends on the complexity of manufacturing, the qualifications of the master and starts from 100 dollars. The purchase of a finished fireplace will cost you at least 40 dollars, and its installation services — from 20 dollars.
Economical diesel heat guns
There are several variations of heat guns. They can be portable and stationary, use various energy carriers. In our case, we consider stationary diesel gunsequipped with a system for removing combustion products. This equipment is the fastest way to warm up the room.
It cannot be called completely non-volatile, since it uses a blower fan, so you have to use a battery or a diesel generator in parallel.
But heat guns are an ideal tool, for example, for a short winter visit to a summer cottage.
The purchase of a liquid-fuel heat gun capable of heating a room with an area not exceeding 80 square meters will cost a minimum amount of 100 dollars.
Installation and installation of a pipe outlet for combustion products can be done independentlyit is enough to adhere to all the conditions described in the attached instructions.
This equipment belongs to a fairly new category of devices capable of extracting thermal energy from the environment, namely, using solar energy.
The collectors are designed to heat the coolant, the energy of which is then used to heat a private house without gas and electricity or household needs (if water is used).
There are two main design variations of solar collectors:
- flat, capable of heating the coolant up to 200 degrees;
- vacuum, heating the coolant up to 300 degrees.
Flat-plate collectors are much cheaper, but less efficient in cloudy winter conditions. A standard minimum set of equipment with a thermal power of 2 kilowatts will cost 160 thousand rubles, installation and connection to an existing heating system will cost at least 100 $, and operating costs, subject to all recommendations, are zero.

Many of the above alternative heating systems require significant upfront costs, but they often pay for themselves faster than schemes using mains energy sources.
