A reason to think carefully again: how profitable is a gas boiler? Pros and cons of the device
There are different types of heating systems on the market, but gas boilers are the most reliable and economical.
Natural gas is used as fuel for them. methane or propane-butane. The main share of natural gas is methane (more than 70%).

Advantages of gas boilers
Gas boilers have become widespread, because they are practical and easy to use, and are distinguished by moderate prices for equipment and for the process of further operation.
Autonomy
Autonomous or independent devices are called do not require a permanent connection to general communications.
If you drill a well and make a volumetric reservoir, then in the plan water supply the house will be considered autonomous, since it does not depend on the centralized water supply. A similar system operates for a gas boiler.
If there is no gas pipeline nearby, and heat with wood and coal if there is no desire, then installing a boiler that works on natural or liquefied gas, will significantly simplify and reduce the cost of heating your home.
Reference. Autonomy is achieved due to the fact that the gas is located in cylinders. Therefore, it can be transported anywhere. It is enough to allocate a small space for the cylinders and connect them to the system.
The downside of cylinders is that they rapid devastationIn this case, either mobile gas tank, or stationary, which holds a much larger amount of gas and is able to heat the house longer.
High efficiency
The average efficiency of a properly operating gas boiler is more than 90%. It all depends on the type of fuel, type of device, ambient temperature and other factors.
Some units have significantly higher efficiency - about 95%, for others - slightly lower. Therefore, the figure of is taken as the average indicator. 90%.
This is the meaning in any case higher, than boilers on solid fuel. What remains from the combustion of gas minimal amount of "waste", but they are released into the atmosphere as carbon.
And if we add to this factor low price of fuel, then the gas boiler becomes an economically advantageous heating device.
Long service life
Boiler service life depends on several factors:
- From prices.
It is logical to assume that cheap the unit is unlikely to last long enough, because during its production money was saved on equipment, on safety systems, on the quality of the material. The average service life of an inexpensive boiler is about 10-15 years, while qualitative the device is capable of working 20-25 years old.
- From correct operation.
If there are power outages in your apartment or house, it is better to purchase uninterruptible power supply system on-line.
It rectifies the incoming current and does not allow voltage surges, instantly switching to its own resources. This is a precautionary measure will allow you to save the most expensive part of the boiler - its electronics, the price of which can be from one third to one half of the cost the boiler itself.
- From fuel quality.
At first glance, it may seem that gas is not diluted. In fact, like diesel and gasoline, gas may also be far from the highest quality. Therefore, it is worth buy it only from trusted suppliers.
All these measures will allow you to extend the service life of the boiler as much as possible.
Compactness
Gas boiler does not require large spaces for its location. The device can be sized a little bigger than a washing machine. This makes it possible to install the unit almost anywhere: in a bathroom, toilet, hallway, storage room, boiler room (if any). Even a small apartment can accommodate a gas boiler, which will be an additional source of heating.
The lack of storage space can only be considered a positive thing if the living space connected to the main gas pipeline system.
For full operation, such a boiler requires just a connection to the gas pipe.
On the other hand, autonomous gas devices imply the need for organization places for cylinders or gas tanks.
If this causes inconvenience to the apartment owners, then in a private house you can find a place for the device or create it. In this regard, it is much more convenient to have stationary gas holder.
He burrows into the ground and formally does not require any space in the house or on the street, and thanks to its large volume it is filled once a yearWith moderate gas consumption and an insulated house, the gas tank will last for a long time.
Ease of use
It will not be difficult for an adult to understand the basic functions of the boiler, find On/Off buttons, and also valve for gas supply. The system is assembled in such a way that its owners can easily perform the necessary manipulations.
Disadvantages of boilers
Disadvantages of gas boilers A little, however they are quite significant.
Obtaining permission for installation in a house or apartment
This requires compliance several aspects:
- premises, where the gas boiler will be located, is mandatory should be fenced off from other rooms by walls and doors;
- necessary install a gas meter — this rule is not mandatory in the documentation, but without it, permission will not be issued.
Attention! Gas belongs to explosive substancesTherefore, it is quite logical that a boiler, as a potentially dangerous object, can only be installed after receiving the appropriate permission.
An application for installation is submitted to the supervisory authority., as a rule, it is either Gorgaz (in the city), or Regional gas (in the region). To obtain permission, you must:
- Develop technical specifications for connection to the gas main - is in progress from two weeks to a month, all the main connection points are taken into account. The issuance of TU actually gives permission to develop the project.
Photo 1. A similar diagram of connecting a gas boiler to the heating system will be required to obtain permission for installation.
- Entrust the gasification project to specialists from the regulatory authorities. According to the law, any licensed design office has the right to develop the project, but it is better to contact a government specialist. The production period is from two weeks to one month.
- Coordinate documents in Gorgaz and obtain permission to install a gas boiler. To do this, you must provide the TU, gas supply project and building plan, Rostekhnadzor permit and other technical documentation for the boiler being installed.
Reference. All the legal formalities may take from three months to six months.
Sensitivity to failures and risk of leakage
As well as electricity and gas networks the main supply cannot boast of stability work. You need to be prepared for this and, if possible, have the contacts of a technician on hand who can quickly fix the problem. Autonomous boilers are practically free of this drawback., since gas is supplied from the storage facility steadily. You just need to monitor its quantity and replenish the stocks in time.
Important! Subject to compliance safety rules, timely replacement hoses, isolation The mounting points are sealed from leaks using plumbing thread, making the boiler easy and safe to operate.
Leakage gas is not a common but possible occurrence. Timely diagnostics hoses and connections will help to avoid negative consequences.
Special requirements for the room with the boiler
The following requirements apply to the placement of gas boilers: increased demands:
- The gas boiler must be located in a separate room, separated by walls and a door.
- The premises must be uninhabited and preferably dry.
- The volume of the room cannot be less than 8 sq. m.
- The device must have presence of a chimney for exhaust gas removal and supply ventilation (requires a constant supply of oxygen).
The need for a chimney and automatic control unit
Gas, like any combustion product, is capable of releasing not only heat, but also residual substances. In firewood it is ash, in gas it is also gas, but of a slightly different structure. One way or another, it is harmful to health people. To avoid carbon monoxide poisoning, it is necessary to install a chimney through which the waste material will be removed into the atmosphere.
Reference. The automatic control unit of the gas boiler performs an extremely important function - it ensures that the equipment operation was clear and uninterrupted.
The control unit includes:
- gas fittings;
- valves;
- maximum and minimum pressure relays;
- thermostats;
- controllers.

Smart Choice: Weigh the Pros and Cons
Choosing a gas boiler as your main heating source - the idea is rational from almost all sides. And with autonomous use, and with main gas, gas is in any case cheaper than other sources.
With the right approach and periodic diagnostics The equipment can serve for years, providing a house or apartment with relatively cheap heat.
