Today, undoubtedly, the most affordable, efficient and economical option for heating residential buildings is gas water heating. For apartment buildings, in the private sector, in places where there is a centralized gas supply, gas is becoming the main type of fuel. However, when the heating season is in full swing, situations often arise when the allotted limits on gas consumption are quickly exhausted. What to do in such cases? How to save gas in a private house, thereby reducing heating costs? The only way out in such situations is to have auxiliary heat sources on hand.
What are the best heating alternatives to gas? How much something costs and what effect is achieved in this case is a problem with several unknowns that we have to solve.
There is no gas — we consider all possible methods of heating
Increased financial costs for heating a residential building during the cold period, excessive consumption of blue fuel, a common and well-known situation for many owners of private houses. Let’s try together to find the best way out of this situation. The main condition, which is relevant in this case, is to obtain economical heating, which is not inferior in its technological parameters to the gas water heating that is familiar to us.
Having assessed all the technical capabilities of various heating options, we will dwell on each of them in more detail.

The most proven and oldest method of heating a residential building is stove heating. In rural areas, in the private sector, you can still find houses where a traditional stove stands not just as an element of ethnic decor, but as an important component of home life. Combination ovens are mostly common, which play the role of a heat source and serve for cooking. The presence of a stove in the house will save gas, especially if there is an abundance of firewood and their quantity is not limited.
If such a stove is available in the house, the issue with an alternative option for heating the house has been resolved. Despite the existing shortcomings that are characteristic of stove heating. When the house is warm at a relatively low cost, few people pay attention to the soot and soot present in the room. The only aspect that remains in attention is the fire safety of stove heating.
Important! The oven needs constant cleaning. The optimal operating mode depends on the condition of the chimney. Good draft avoids the accumulation of hazardous combustion products, and fresh air access guarantees an acceptable level of CO2 in room.
Another equally convenient option, if there is no gas, is to use liquid fuel heating systems. The main type of fuel in this case is diesel fuel. Less common are boiler models that run on rapeseed oil or kerosene. Heating a private house in this case will be effective, given the high efficiency of liquid fuel boilers. Heating of residential premises with diesel fuel is used quite rarely. The reason for this is the difficulty of storing large volumes of diesel fuel and the high fire hazard of such heating systems. And who will like the constant smell of diesel fuel in the house, the eternal dirt and soot.
The use of solid fuel in cases where gas needs to be saved is the best option. In our country, neither firewood, nor coal, nor peat are outlandish, therefore it is convenient, rational and efficient to use them as fuel, from an economic point of view. We have already talked about a home stove, the option remains with the installation of solid fuel or universal boilers. It is up to you to decide what is more profitable to heat with wood or coal. It all depends on the availability of each type of fuel in a particular region.
Modern technologies have stepped forward, providing consumers with a wide choice of models of equipment that, through the combustion of solid fuels, has a high heat transfer. Solid fuel pyrolysis boilers have a fairly high efficiency, about 80%, are equipped with automation, do not require the constant presence of a person and frequent fuel loading. Solid fuel is still the cheapest way to heat. It is up to you to evaluate the existing disadvantages of such heating options, especially when there is a question of quick and efficient replacement of the missing gas.
Combined, multi-fuel boilers, offered today by many firms and companies, have a high cost. Due to objective reasons, such equipment has not yet found its niche in the consumer market, given the financial capabilities of the population.
Important! Before you take up the calculator and make calculations of the efficiency of heating a private house without gas, it is necessary to eliminate the confusion between volumes measured in cubic meters. meters and the mass of fuel, measured in kilograms. All types of fuel, except for electricity, are best measured in kilograms, since the calorific value of the fuel is related to weight.
Here it is appropriate to conduct an unbiased analysis of the efficiency of using different types of fuel. The above table will give you a visual idea of what type of fuel is most efficient today, the cheaper it is to heat a house.
These tables allow you to make simple calculations yourself by substituting the current cost of fuel.
The cost of thermal energy obtained by using each type of fuel is calculated as follows:
We divide the approximate cost of fuel in your region by the specific calorific value of the fuel. We divide the data from the second column by the parameters indicated in the third column. In the fifth column we enter the data from the calculation:
- for heating a private house in 100m2 during the heating season, 5 kW / h will be required;
- 24, the number of hours in a day;
- we take into account the duration of the heating period — 180 days (6 months).
As a result, we get: 5 x 24 x 180 = 21600 kW / h.
As can be seen from the table, the data for all types of fuel used in our homes are the same. This indicates approximately the same efficiency of the proposed heating options. The only amendment is possible when it comes to different sizes of the building. The domestic intensity of the use of heating devices and the thermal efficiency of a private house play an essential role. The value of 5 kW / h taken into account is typical for a building well insulated with modern materials. The duration of the heating period may also vary depending on the climate of the region.
We multiply the cost of 1 kWh of thermal energy in each individual case by the total number of kilowatt hours, we get the cost of each type of fuel. We divide the obtained figures by the theoretical value of the efficiency of equipment for burning each type of fuel, we get the actual efficiency parameters and the answer — the more profitable it is to heat buildings without gas.
Also, do not forget to get acquainted with the methods of saving on heating in the apartment.
Electricity is a worthy replacement for gas due to its absence
Economical, efficient heating of a private house, dacha without gas should be more focused on maintaining familiar living conditions. The level of comfort determines the choice of an alternative method of heating, in addition, today technology provides ample opportunities for maneuver. To achieve gas savings in the cold season will allow the availability of electricity. Not without reason, many owners of country houses and country cottages, due to the lack of technical possibilities for connecting to a gas main, prefer electric heating systems.
Compared to other heating devices, electric heaters have almost 100% efficiency. A boiler powered by electricity is easy to maintain, inexpensive. In this case, the need for exhaust and chimney equipment is eliminated. Electricity is by far the most affordable alternative to gas heating in terms of efficiency and serviceability.
Main article: cottage heating with electricity.
In addition to installing an electric boiler for a water heating system in a house, convectors, heat guns and infrared emitters are actively used to heat residential buildings of a small area. A fashionable phenomenon today is the equipment of underfloor heating in a private house. The technology is quite new, however, has already managed to prove its effectiveness. A variety of offered heat sources give you the opportunity to choose the best way to heat your home.
On a note: In the event that a warm floor is the main source of heating for residential premises for you, the power of the equipment should be 150-180 W per m2 living area. Warm floors should have an area of at least 70-80% of the total area of the building itself. Otherwise, the expected heating effect will be negligible.
When heating a private house in other ways, even higher economic indicators can be achieved. Without gas, an economical and uninterrupted source of thermal energy on your site can be obtained using a heat pump. The principle of operation of the equipment is based on the temperature difference, in the depth of the soil and on the surface. With the help of a heat pump, which really costs a lot of money, you can provide yourself with an almost eternal source of heat in a country house. The effectiveness of this system is confirmed by simple calculations. An indicator of the successful operation of a heat pump is the heat conversion coefficient (COP).
For example. When the heat pump consumes 1 kW of electricity required to ensure the operation of the entire system (Ptn), the heat conversion coefficient (COP) is 3.0, which means:
Ртн x СОР = 3 kW Рp of energy at the output. Savings and efficiency of this method of heating is more than obvious.
There is no single answer to the question of whether it is more profitable to heat a private house with gas or other types of fuel. In each individual case, the presence of a variety of factors plays a role, among which the economic and technical capabilities of the consumer occupy not the last place.
Almost any fuel can be used instead of gas for heating. Another thing is how much you can fully heat your own house in cold weather, create comfortable living conditions for yourself. Faced with this situation, the choice is yours. How to save money, make your heating costs optimal depends on you, on your attitude to the very fact of energy savings and technical capabilities.
