Quite often, owners of real estate for various purposes are faced with the fact that it is not possible to connect to centralized heating. If you have already gone through all the options, you should pay special attention to liquefied gas. By calculating the consumption of this fuel for heating your home and weighing whether this method of heating your home is rational, you can make a choice.
What is LPG
Liquefied gas is natural gas that has changed its state of aggregation and turned into liquid, having decreased in volume. The transition requires high pressure, normal temperature. As a result, a larger volume of fuel is placed in gas storage tanks. Cylinders are filled with a mixture of butane and propane, which is under high pressure, remaining in a liquid state. This simplifies transport and makes fuel safe.
Types of fuel for filling cylinders
Today, three fuel options are known,with which the cylinders are filled. This is:
- summer butane/propane technical blend;
- technical butane;
- winter propane/butane blend.
In order not to face the problem of the impossibility of heating due to high frosts, the boxes where the cylinders are located should also be insulated. You can additionally equip the space with a heater.
How to store cylinders
At low temperatures, the gas does not freeze, but turns into a liquid, and in this state it does not enter the heating system. This condition causes the mixture to boil when the temperature drops to -10 ˚C. The pressure drops. In order not to encounter this, in addition to heating and insulation when the cylinders are located outdoors, they should be blown from the boiler room through the air ducts.
Security Reviews
Liquefied gas is heavier than air. If it leaks from the cylinder, it collects above the floor surface, and you can feel it in the room when it reaches a critical level, which is accompanied by the risk of an explosion. For this reason, it is better to install gas on the street, placing it in a metal compartment. The balloon must be oriented vertically.
If you decide to use liquefied gas heating, then consumers are advised to equip the fixture to accommodate them with ventilation holes. It is strictly forbidden to place cylinders under the house in the basement, this also applies to the pits in the yard. Buyers warn when using liquefied gas fromsome possible scenarios. For example, it is strictly forbidden to heat a cylinder with heating elements or electrical appliances if it is frozen. In order to exclude ultraviolet radiation, the structure with the installation should be located on the outside of the dwelling, it is better if it is the north side.
Additional consumer opinions on heating safety
Cylinder filling is less than 80%, the rest of the space is given for expansion. Heating with liquefied gas, as consumers emphasize, can be dangerous. In this regard, cylinders should be periodically checked for fuel leakage. Gas pipelines must be made of strong and reliable materials.
Reviews on Key Benefits
In suburban dwellings, the presence of gas cylinders does not surprise anyone. People continue to use such fuel in the kitchen if gas is not brought to the house. But recently you can hear that dwellings are heated with liquefied hydrocarbon gas. The purchase and installation of equipment and heating systems of this kind have become available to the general population.
If people are unable to use centralized gas for heating, they install appropriate equipment to provide heating with liquefied gas. Consumers emphasize that this fuel use option has certain advantages. Firstly, you will have the opportunity to make the heating autonomous, refusing to use its centralized supply. In-secondly, gas can be used year-round. Thirdly, as consumers emphasize, the system will have high reliability and quality.
Additional benefits
Minigas tank for heating on liquefied gas can be placed underground. It will be invisible to the eye, it has a small size. You may also like the convenience of delivering raw materials, and the construction of a pipeline is not required. As the owners of houses emphasize, liquefied gas is more heat-intensive compared to natural gas. The raw material is environmentally friendly. Compared to other heating options, the cost of gas is low and not affected by natural gas price fluctuations.
Negative reviews
Heating on liquefied bottled gas, according to consumers, has its drawbacks. If the dwelling is located far from the city, then the cost of raw materials increases due to shipping costs. When it's freezing outside, using LPG can be accompanied by the risk of freezing the reducer.
Customers also don't like the fact that getting new supplies of fuel can be difficult due to weather conditions when the roads are swept up. Before you start designing the heating of a private house with liquefied gas, you should also pay attention to the fact that installation of such a system is allowed only by qualified specialists. You can only make the simplest knots on your own.
Reviews on heating features
Perhaps the most important inconvenience is that the owner will have to control the level of gas, replenishing it in time. For some, it is considered an advantage when you can enjoy the benefits of complete autonomy and independence from the central gas supply. For other consumers, this is a disadvantage. However, with responsible management of fuel levels, there will be no interruptions and problems with heating.
If you want to equip heating with liquefied gas, you must remember that a 50-liter cylinder is filled with fuel and can be used for small cottages, summer cottages and houses. Every few days you will have to change an empty cylinder to a new one, which can be inconvenient, so experts advise connecting several cylinders by looping them. Consumers emphasize that when installing a liquefied gas heating system, it is allowed to form a battery of three cylinders. If you want to combine more of them, you should prepare a draft and related documents.
Cylinders cannot be installed inside the house, they can be placed on the outside, where they will be in a metal cabinet. In frosty weather, condensation may occur or the gearbox may freeze. This will hinder the flow of gas. To avoid such inconvenience, consumers are advised to install an electric heater in the closet. Such a system can be convenient if the area of \u200b\u200bthe house is not very large and there is confidence that problems withdelivery of raw materials will not arise. When this moment is in doubt, it is better to purchase a gas tank.
It is a bunker for liquefied gas filling and storage. Such a reservoir is filled 1 or 2 times every three years. The reservoir may have a different volume. You can choose it according to your needs. This parameter varies from 3 to 10 cubic meters. You can place the gas tank at a distance of 10 m from the dwelling. If you plan to equip a private house with liquefied gas from a gas tank, you will need to provide a convenient access road to it.
Cost of gas tanks and fuel consumption
The cost of equipment is affected by the size of the tank. The larger the gas tank, the more expensive it will be. This does not mean that small volume gas tanks are more cost-effective. A small tank will need to be refilled more often. This suggests that the owner will have to pay for fuel delivery more times.
If you are still wondering whether it is worth resorting to this type of home heating, you should read the reviews. The cost of heating on liquefied gas can also affect your choice. It is possible to calculate the volume of the tank, given that approximately 25 liters of gas per year will be required per square meter of the room, which depends on the heat loss of the house and the number of people. It is important to remember that the container is 80-85% full - you should leave room for gas expansion and evaporation.
More often, owners purchase gas tanks, the volume of which varies from 4800 to 6400 liters. This is enough forneeds of a medium sized home. The manufacturer and quality affect the price of tanks. Czech companies produce gas tanks, the cost of which is 160,000 rubles. You can buy a gas tank from an Italian company for 170,000 rubles. The most popular are Russian tanks from the Medved company. Their cost is the lowest and amounts to 125,000 rubles.
The price of a gas tank for a private house will be 350,000 rubles if you purchase a Polish-made product that belongs to the premium class. It is important to remember that the installation of equipment also costs money. Typically, these works cost 50,000 rubles. The final price will depend on the length of the gas pipeline, the size of the reservoir, the presence of additional gas pipelines and other conditions. The price of a gas tank for a private house is not all that should be considered. It is important to invest in the estimate also earthworks. They will cost you about 15,000 rubles.
Fuel cost
Before you equip the described type of heating, you must calculate the cost of gas. The price of a liter of fuel is constantly changing, today it is about 15 rubles. On average, gas consumption from the tank for heating is 25 liters per square meter per year. If you are interested in the question of how much liquefied gas costs for heating, then you should consider that for a small house of 100 square meters, approximately 2,400 liters per year will be needed, which is 36,000 rubles.
Recommendations for choosing a boiler
When choosing boiler equipment that will work onliquefied gas, power should be taken into account. Looking into the device passport, you will see this value indicated in kilowatts. Quite often, manufacturers also mention the heated area, which is 9 times larger.
If we take as an example a boiler for heating on liquefied gas AOGV-11, 3, whose power is 11.3 kW, then it is designed for a building of 100 square meters. However, this is not entirely correct. The equipment will heat such an area, but with severe frosts it will be cold in the house for several weeks.
