Individual heating of a private house with liquefied gas

Heating with diesel fuel

For heating with diesel fuel, a tank will also be required, and the cost of installing it will be comparable to the cost of autonomous gasification of a house. At the same time, unlike propane-butane, diesel fuel cannot be called cheap.

High price. Diesel fuel is the most expensive source of energy used for autonomous heating of a private house. A kilowatt-hour of diesel fuel costs . Even electricity is a little cheaper. It will probably be difficult to spend more on heating.

Bad smell. This is an inevitable property of diesel fuel.A strong smell will follow the unfortunate owner of a diesel tank everywhere. The house will smell like a garage, and the yard will smell like a working tractor, and there's nothing you can do about it.

Problems when using low-quality fuel. The use of low-quality diesel fuel can lead to serious damage to heating equipment. Those who use liquefied gas and gas tanks AvtonomGaz do not have such a problem: the quality of propane-butane does not affect its consumer properties.

Disadvantages of heating with diesel fuel

• High price.
• Sometimes you have to clean the snow for winter delivery.
• Strong smell in the house and on the site.
• Use of storage space.

We heat the country house with natural gas

Natural gas among other types of fuel is the leader. In the presence of a modern efficient boiler well insulated house heated at minimal cost. Of course, there are cheaper sources of energy, but they are not autonomous: solid fuel must be constantly supplied, electricity can be turned off, gas in cylinders and does periodically run out.

Features of using gas boilers

When choosing a boiler, you need to proceed from the area of ​​\u200b\u200bthe house and the hydraulic calculation. A wall-mounted convection boiler can cope with heating a three-hundred-meter house. You can install condensing equipment. It is suitable for houses up to 400 m 2. Such boilers use not only fuel energy, but also steam condensate. Their energy efficiency is much higher. If suddenly the performance of the equipment is not enough, you can use the "cascade connection" function.

A few years ago, the cost of a heating boiler was very high. But now that this equipment has become quite affordable, use natural gas for heating the house and organizing hot water supply is more profitable than any other fuels

Hot water can be provided by an electric boiler, but if the heating of a private house is based on the use of natural gas, it is more economical to use it for water heating. To do this, you need to purchase either a double-circuit gas boiler, or supplement the existing tank. You can choose the volume based on domestic needs. Boiler columns keep a stock of water of the necessary temperature. The flow gas boiler heats the water at the time of supply. After opening the tap, cold water will first go down, and only then hot water will go.

Diagram of the device of such a system

The scheme of the gas heating system of a private house includes a heat source, from which the coolant first diverges through the collector through pipes to the radiators, and then, cooling down, returns to the boiler. The fluid is under pressure. The circulation in this case is forced. Additionally, air vents, stopcocks, flow and temperature sensors, thermal heads can be installed. The automatic control helps to regulate the temperature.

The system can also be designed for natural circulation, then the expansion tank is included in the circuit in highest point at home. Here you can save on temperature sensors, air vents and expensive pumps.

Heating wiring can be radial or tee. The first is more expensive due to the larger footage of the pipeline, but more efficient and mobile, it is easier to repair during the heating season.The second one is cheaper due to the smaller number of pipes, but it does not provide such wide opportunities for temperature control in individual rooms as radiant wiring.

The number of radiators in the system is determined on the basis of thermal and hydraulic calculations. This is the most correct option both technically and economic point of view.

You should not rely on the advice of unskilled sellers and outsiders: the number of sections does not need to be selected based only on the area of ​​\u200b\u200bthe room.

Natural gas heating equipment requires minimal maintenance, which, by the way, can be done on your own. The fuel burns without forming a solid residue. In order not to install a chimney, you can purchase a boiler with a closed combustion system.

If there is no gas main by the end of the construction of the house, you can purchase a boiler for two types of fuel. After gasification, the transition to economical and efficient natural gas will not require significant material costs. The maximum will need to call a specialist from a service company.

Centralized or autonomous gas supply?

Without combustible fuel sense from any version of the in-house heating system in standalone execution will be zero. Gas is the first thing to think about when planning gas heating in a country house.

Not all settlements in Russia are supplied with gas. However, “blue fuel” can be obtained not only from pipe or cylinder with liquefied fuel, but also from a gas tank.

Natural gas, which consists mainly of methane, is supplied to private homes through pipes. Its liquefied counterpart is a propane-butane mixture, which is pumped into containers for transportation and storage.The pressure in such cylinders and gas holders is about 15–18 atmospheres.

When organizing heating in a private house using balloon containers of 50 liters, the latter will have to be changed every 2-3 days in winter. If a for a country cottage Since autonomous gas supply is chosen, it is best to prefer a gas tank, which can be up to 20 cubic meters in volume.

The choice of capacity by cubic capacity depends on the level of consumption liquefied hydrocarbon gases (SUG). Here it is necessary to take into account not only the boiler, but also the fireplace and gas stove, if they are used in the house.

For a cottage of 150 sq.m. it is recommended to install a gas tank with a volume of 2000-3000 liters. And for a country dwelling of 300 sq.m. you will need an option for 8000-9000 liters.

If there is no gas main in the village, you can use the option with an autonomous fuel supply from a gas tank designed for gas storage in liquefied state

In terms of connection costs, a gas pipeline is in most cases more advantageous than a reservoir in the ground. But only when the settlement is already gasified.

There are also situations in which the installation of a gas tank will cost less than connecting to the main pipeline. It all depends on the specific connection conditions in the region and the remoteness of the village from a large gas pipeline.

When using a gas tank, you do not have to worry about the presence of pressure in the pipe. It is extremely easy to operate. It is only necessary to regularly call specialists to check it for safety, and also do not forget to refuel. It will take no more than three days to install the entire system.

If an autonomous gasification option is chosen, then the gas boiler should be purchased one that is designed to run on LPG. AT there are models for saledesigned to operate exclusively on mains natural gas.

But most gas heat generators are designed to burn both types of this fuel. You only have to change the jets, as well as reconfigure the valve and electronics to a different mode.

The main disadvantage of the gas tank is that it can only be installed on a large area, the tank, according to the requirements of SNiPs, must be at least 10 m away from the house

Liquefied gas in the house: features, preparation

To organize this type of heat supply to a dwelling, special containers for fuel are used - gas holders. Located underground, the tanks feed the thermal unit, ensure the continuity and efficiency of work.

As a rule, gas tanks are installed at a distance of more than 10 meters directly from the house itself and 2 meters from all kinds of communications.

gas holder

There are a wide variety of containers on the market today. propane-butane mixture, among which you can easily choose the best option for each specific house and boiler, thereby providing housing with high-quality heat.

For heating a private house with liquefied gas, as a rule, boilers with a capacity of 18-90 kW and capacities of 3-9 cubic meters are sufficient for fuel storage. The storage is filled by 85% from a special tank truck, which delivers propane-butane as it burns in the boiler.

Heating system on liquefied gas

The main advantages of heating with liquefied gas

Currently, heating a private house with liquefied gas is a process that has many advantages over more traditional options.

Among the main advantages of this method are:

• the possibility of using liquefied gas all year round;
• convenience in delivery, operation and storage of fuel. Many photos of such heating systems show that the gas tank is compact and does not take up much space on the site, as it is buried in the ground;
• environmental friendliness - during combustion, gas does not emit such an amount of harmful substances as the same diesel fuel or gasoline;
• durability and reliability of the heating system.

Refueling the gas tank

Stages and features of the organization of heating using liquefied gas

Installation process, which requires heating the house with liquefied gas, does not forgive amateur performance. The design, installation of the gas tank and all additional equipment must be carried out by professionals who have all the permits, and their activities are licensed.

Today, the autonomous gas supply market is rich in various offers from companies that have extensive experience and are able to create the most optimal gasification system for any facility.

Nevertheless, despite all the complexity and increased requirements, do-it-yourself liquefied gas heating can still be done. To do this, it is necessary to know the main stages of work, their features and requirements.

Such an instruction will help ensure high performance, reliability and high quality of the heating system, as well as the safety of its operation.

System design

The initial event, during which the type of system, price, performance and many other parameters are determined.
At this stage, it is important to comply with all the requirements of the standards and regulations of SNiP, because without them it will be impossible to start the equipment and ensure its normal operation.

Supply of equipment. As a rule, today there are no problems with equipment for autonomous gas supply, because many companies offer a lot of options, ranging from budget ones to more expensive ones.
With all this, each consumer can view a video of the operation of the equipment, thereby making sure of its performance and functionality.

Installation and commissioning

You can, of course, do all the work yourself, but it is best to entrust them to qualified professionals - this is the only way to ensure that the autonomous heating of a country house with liquefied gas will work efficiently and without fail, and remain safe for a long time.

Liquefied gas in cylinders: compact and cheap

For those people who do not want to install gas tanks on their site, heating a country house with liquefied gas in cylinders can be an excellent alternative.

In this case, the entire heating system will operate on the same liquefied gas, but it will no longer enter the boiler from a large gas tank, but from compact but capacious cylinders.

This heating option will be an ideal choice for small cottages, summer cottages and other buildings where the size of the site does not allow the installation of even the most compact gas tanks.With all this, the cost of maintenance and the fuel itself will be more than affordable.

Design and documentation

A “personal” gas system must be as reliable and safe as a centralized main. Carelessness in these matters is unacceptable, since even a slight gas leak can cause huge problems up to and even lead to loss of life.

If the owner of the house does not have special knowledge, then the design of the gas pipeline must be entrusted to a specialist with a license.

The installation location of a ground or underground gas tank is determined not only by convenience, but also distance for individual objects on plot (+)

Rather, this is done by entire design organizations that have the right to design and carry out work on the gasification of residential facilities.

It can be either a private company or a specialized subdivision of the gas service of a district, region, etc. Private traders charge a little more for work than state specialists, but they will also take care of the design.

When working with regional gas, the owner of the house will have to deal with the design on his own, but you can save a little.

When drawing up a project, you will not only have to draw up a couple of statements, but also attach a number of documents to them:

• owner's passport;
• certificate of ownership of the land;
• site plan;
• characteristics of the heating system, etc.

First, specialists develop technical specifications for the gasification of a building, which take into account fire safety requirements. Then, field studies are carried out, and a place is selected for the installation of a gas tank, taking into account the standards.

The gas tank must is at a distance:

• at least 10 m from residential buildings;
• at least 15 m from sources of drinking water and other water bodies;
• at least 5 m from trees and outbuildings;
• at least 2 m from fences.

In addition, it is necessary to take into account the presence of power lines near the installation site of the gas tank. The minimum distance to such structures should be half the height of the support. Another important point is the availability of convenient access roads for a car with a liquefied gas tank to fill the gas tank.

At the design stage, the features of the site are also evaluated: the corrosivity of the soil, the level of stray currents, etc.

Based on these data, a decision will be made on the features of the gas tank, for example, whether it needs additional galvanic protection, which will not affect the price of the device for the better.

Ground models of gas tanks are usually used only in the summer. Such tanks are subject to higher safety requirements than for underground counterparts.

Thus, the technical conditions for the gasification of the facility are determined. With their help, specialists will draw up a project that includes a number of documents: characteristics of a gas tank, evaporator, condenser, site plan, gas pipeline system layout, recommendations for grounding, chemical protection, lightning protection, etc.

These documents must be coordinated with the fire inspectorate, gas supply services, electricians, architects, environmentalists and other specialists of local departments. The result of registration will be receiving building permits.

Installation of an autonomous gas pipeline

If the owner of the site wants to reduce the cost of installing an autonomous gas pipeline, he can dig a pit for a gas tank on his own. But this must be done in strict accordance with the project. It is better to entrust all other work to specialists so that everything is done in full compliance with safety requirements.

When installing an autonomous gas system, external pipe laying should be used; only permanent connections are used to connect individual sections

All gas pipes should only be laid openly, they should not be hidden under a screed, false panels or other decorative elements. Carefully consider the layout of pipes for liquefied gas.

It is not allowed to carry out such communications in transit through living quarters, through a kitchen or other utility rooms in which appliances that operate on liquefied gas are already installed (or will be installed).

The process of installing a gas tank in a pit includes a number of traditional steps:

Another categorical prohibition associated with the installation of gas pipes is detachable connections. Of course, connectors are needed at the beginning of the network, i.e. where the network is connected to cylinders or a gas tank. And at the end, when connecting the pipe to the boiler or column, it is also necessary to put a connector.

But along the entire length of the autonomous gas pipeline, the connections must be made only one-piece. The part of the gas pipeline that is laid outside needs to be taken care of additionally.

The entire external network should be carefully insulated using special materials that are resistant to fire. In addition, it is necessary to ensure the removal of condensate, this will reduce the likelihood of pipe corrosion.

To reduce the cost of installing an autonomous gas pipeline, you can dig a pit for an underground gas tank yourself, but you must follow the project documentation

The gas boiler must be installed in a separate room - the arrangement of the boiler room will be required. Its volume must be at least 15 cubic meters. m. In the room it is necessary to make a window, the opening area of ​​\u200b\u200bwhich is at least half a cubic meter.

Such a hole in the outer wall will create an outlet for the blast wave in the event of an accident. If the gas explodes in a room with blank walls, the entire building can be seriously damaged.

At the entrance to the boiler room, you should put a door that opens outward. Another point that should not be neglected is the ventilation of the boiler room. The supply of fresh air must be constant to ensure combustion of the gas.

Sufficiently good air exchange must be ensured so that the gas does not concentrate in a room with an open fire in case of accidental leakage.

The gas boiler should be installed in a separate room with a window and a door that opens outwards. Finishing is carried out using fire-resistant materials

Ventilation will also prevent poisoning by combustion products if there are problems with the chimney. If it is not possible to allocate a separate room for the boiler, it is allowed to install some models in the basement or on the ground floor.

But in this case, it is imperative to install a system in the room with the boiler to control the level of hazardous gases in the air.

Installation work on autonomous gasification by a gas tank usually takes two or three days. But after their completion, a number of documents should be drawn up and some coordination should be carried out. Testing the finished system for tightness should be carried out under the supervision of specialists from the regional gas organization and Rostekhnadzor.

Before backfilling the underground gas tank with sand, it is necessary to wait after its installation for about two to three weeks

After checking, the gas tank is covered with sand, after which you need to wait about three weeks before filling the tank with liquefied gas for the first time. Completion of work must be formalized by an official act of acceptance and transfer. At the same time, they usually conclude a service agreement.

Sometimes it is more convenient to invite for installation external and internal gas pipeline different contractors. In this case, experts recommend delimiting responsibility between the performers and formalizing this moment as a separate act. It also does not hurt to take care of civil liability insurance.

Is there an alternative

To date, the following methods of heating private housing are known:

• natural gas coming through the main pipeline;
• electric boiler;
• solid fuel: firewood, coal;
• pellet boiler;
• liquefied gas in cylinders.

Each option has its own advantages and disadvantages. Considering that not even all urban-type settlements have a gas pipeline, it is unlikely that it is connected to a dacha settlement. And if they promise to let her down, then not as soon as we would like.

Heating costs for a house of 200 m2.

The most banal solid fuel today is also not cheap, but the main drawback of this kind is far from price. If you heat the cottage with wood or coal, then you must definitely be there every day.

Electricity is considered one of the most expensive ways to heat a home. Therefore, many use it in addition to solid fuel, to maintain the temperature during periods of absence in the country. The electric boiler itself is much cheaper than a gas boiler, but the price of electricity is growing every year.

Wood fuel pellets (pellets) are widely distributed in Europe, Denmark, Sweden. For Russia, this is still a rare occurrence, but it also occurs in homes where the owners care about the environmental friendliness of fuel. It is convenient that the pellets are poured into a special hopper and automatically fed into the pellet boiler, without any physical effort. Compared to pipeline gas, they will cost 3 times more, unless you include in the estimate all stages of gas pipeline, starting from the project.

Liquefied gas

Many boilers are made in such a way that the same burner can be used when changing fuel. Therefore, some owners choose methane and propane-butane for heating. This is a low density material. During the heating process, energy is released and natural cooling occurs under the influence of pressure. The cost depends on the equipment. Autonomous supply includes the following elements:

• A vessel or cylinder containing a mixture of butane, methane, propane - a gas holder.
• Devices for management.
• A communication system through which fuel moves and is distributed inside a private house.
• Temperature sensors.
• Stop valve.
• Automatic adjustment devices.

The gas holder must be located at least 10 meters from the boiler room. When filling a cylinder of 10 cubic meters, to service a building of 100 m2, you will need equipment with a capacity of 20 kW.Under such conditions, it is enough to refuel no more than 2 times a year. To calculate the approximate gas consumption, you need to insert the value for the liquefied resource into the formula R \u003d V / (qHxK), while the calculations are carried out in kg, which are then converted to liters. At a calorific value of 13 kW/kg or 50 mJ/kg the following value is obtained for a house of 100 m2: 5 / (13x0.9) \u003d 0.427 kg / hour.

Since a liter of propane-butane weighs 0.55 kg, the formula comes out - 0.427 / 0.55 = 0.77 liters of liquefied fuel in 60 minutes, or 0.77x24 = 18 liters in 24 hours and 540 liters in 30 days. Given that there are about 40 liters of resource in one container, the consumption during the month will be 540/40 = 13.5 gas cylinders.

How to reduce resource consumption?

In order to reduce heating costs premises, homeowners apply various measures. First of all, it is necessary to control the quality of window and door openings. If there are gaps, heat will escape from the rooms, which will lead to more energy consumption.

Also one of the weak points is the roof. Hot air rises and mixes with cold masses, increasing the flow in winter. A rational and inexpensive option would be to provide protection from the cold on the roof with the help of rolls of mineral wool, which is laid between the rafters, without the need for additional fixation

It is important to insulate the walls inside and outside the building. For these purposes, there are a huge number of materials with excellent properties. For example, expanded polystyrene is considered one of the best insulators that lends itself well to finishing, it is also used in the manufacture of siding.

For example, expanded polystyrene is considered one of the best insulators that lends itself well to finishing, it is also used in the manufacture of siding.

When installing heating equipment in a country house it is necessary to calculate the optimal power of the boiler and systems operating on natural or forced circulation. Sensors and thermostats control the temperature, depending on the climatic conditions. Programming will ensure timely activation and deactivation if necessary. A hydraulic arrow for each device with sensors for a single room will automatically determine when it is necessary to start heating the area. The batteries are equipped with thermal heads, and the walls behind them are covered with a foil membrane so that the energy is reflected into the room and does not go to waste. With underfloor heating, the carrier temperature reaches only 50°C, which is also a determining factor in savings.

Plumbers: You will pay up to 50% LESS for water with this faucet nozzle

The use of alternative installations will help reduce gas consumption. These are solar systems and equipment powered by wind power. It is considered most effective to use several options at the same time.

The cost of heating a house with gas can be calculated using a certain formula. Calculations are best done at the design stage of a building, this will help to find out the profitability and feasibility of consumption

It is also important to take into account number of people living, boiler efficiency and the possibility of using additional alternative heating systems. These measures will save and significantly reduce costs

Heating with diesel fuel

For heating with diesel fuel, a tank will also be required, and the cost of installing it will be comparable to the cost of autonomous gasification of a house. At the same time, unlike propane-butane, diesel fuel cannot be called cheap.
