Gas heating boilers
There are quite a lot of positive aspects in using gas boilers for heating a home. These include the price of energy resources, the cost of equipment that is affordable to a wide range of consumers, clear and quick installation and high energy efficiency. It is also important to note the fact that using a gas boiler does not require the use of fire and the building of a very bulky firebox.
Even if the installation of a gas heating system is carried out by qualified workers, the choice of such a unit is always made by the homeowner. With a wide range of gas boilers to choose from, choosing the right option can be very difficult.

Types and advantages of gas heating boilers
On the domestic market, gas heating boilers are the most common technical equipment option. This is mainly due to the fairly low cost of natural resources and their availability on the territory.
It is also worth noting that gas boilers for heating home-made houses have a number of positive characteristics that distinguish them favorably from units operating on alternative fuels.
Advantages of gas boilers:
- The device can operate automatically, without human control.
- Compact assembly of the device and its attractive appearance.
- Acceptable cost of equipment.
- Reliability and durability of use.
- Acceptable price for energy units generated by the boiler.
As a rule, devices operating on natural gas are divided into two groups
- Classic type. The operation of such units is distinguished by the heat of combustion together with water gas, part of the energy produced is part of the combustion products.
- Condensation type. The operating principle of such boilers is based on the thermal energy released during the condensation of water vapor. This type of equipment is very economical. Compared to the classic version of heating equipment, its efficiency is approximately 10% higher.
Regardless of what type the boiler is, it can be installed both on the walls and on the floor. All heating systems running on natural gas are single-circuit and can only provide heating to the house, while double-circuit systems not only increase the temperature in the room, but also provide an uninterrupted supply of hot water.
All gas boilers for home heating have an open or closed combustion chamber, which is a classic or coaxial chimney inside the configuration.
The use of gas boilers for heating homes has become the best alternative to solid fuel or electric heating systems.
Most mini-boiler houses are suitable for construction on gas. Manufacturers offer a large number of heating device models to choose from. Their modifications depend on the energy source – natural gas or liquefied gas.
Classification by installation location
There are many types of gas appliances. Depending on the location and method of installation, the following types of floors, walls and parapets are distinguished
Floor-standing devices
This type of heating system is a classic model of gas boilers with very high power. As a rule, they are used to heat fairly large areas (industrial or public buildings). In addition to the heating function, such boilers also heat water both for human needs and for the functioning of a water bed, if necessary. For this purpose, the design of the heating unit includes a dual-circuit system. In such units, the heat exchanger is traditionally made of cast iron or steel and can weigh up to 100 kg.
Attention! In order for a floor-standing boiler to work without problems, the chimney must be installed at a height of approximately 50-60 cm above the roof ridge. This provides good traction.
Premises in which floor-standing boilers are installed must have external doors 80-90 cm wide for fire protection.
It is also very important that the installation of external gas appliances and connections to the gas main are carried out only by professionals authorized for this type of activity.
Wall-mounted gas appliances
This type of boiler appeared on the market relatively recently and quickly gained wide popularity. This popularity is due to their attractive appearance and small size, which allows the heating system to be placed in kitchens and other less spacious rooms.
Although this type of boiler is very small in size, it contains all the basic functions found in floor-standing units. The only thing that distinguishes this type of boiler is that it is not very powerful.
The compact and aesthetic appearance of the device hides behind the lid many elements that make wall-mounted gas boilers as efficient as possible, for example, a gas burner, an expansion tank and a pump for circulating coolant.
It is important to note that, despite its small size, this type of heater heats well not only the room, but also the water. The control of such boilers is automatic, which minimizes human influence on the operation of the boiler. It is enough to set the temperature parameters. The safety of the description is ensured by special sensors that turn off the device when the gas supply is interrupted and restart the boiler when the gas supply is resumed.
Parapet boilers
These heating devices are also called smokeless boilers. To install parapet-type heaters, a chimney is not required, since all combustion products are removed using a special coaxial chimney.
This type of boiler can be installed in any part of the house. As a rule, they are used for heating small country houses and apartments. Despite the low energy consumption, this device is able to provide a comfortable temperature, as well as an uninterrupted supply of hot water.
The main feature of wall-mounted chest boilers is that heating and hot water can be connected from different sides of the central gas main. This design feature of the heat exchanger allows you to connect the boiler even in very limited space.
Classification by functionality
When purchasing a heating boiler, the homeowner must clearly determine the purpose for which this equipment is needed. Presumably, in addition to hot air, the ability to heat water will be required.
Single-circuit heating systems can function normally with only one function – either heat supply or hot water supply. However, this problem can be successfully solved by installing an electric boiler for domestic use. It should be understood that choosing this system to provide your home with heat and uninterrupted hot water will cost a significant amount of money.
Choosing a double-circuit gas heating boiler solves two problems at once. It heats your home and heats water according to your personal needs. It is also worth noting that such devices take up less space, and buying one double-circuit boiler is much cheaper than purchasing a gas boiler and boiler.
Heating devices with dual-circuit systems either operate in flow-through heating mode or have an internal built-in boiler. The latter option is most suitable for large families where water consumption increases significantly.
Depending on the power, gas heating boilers can be divided into single-stage and two-stage.
Single-stage boilers operate at one power level and therefore do not use gas as efficiently. Considering the fact that private houses are heated for five months a year, the full power of the equipment is not always in demand.
In this regard, two-stage heating devices are more economical.
Their devices allow:
- Individual regulation of gas supply.
- Saving energy consumption.
- Reduce the frequency of boiler switching on, thereby extending the service life of the device and limiting the release of harmful substances into the environment.
As a rule, two-stage heating systems are equipped with smooth switching (modulation) of gas consumption. This function significantly saves energy consumption and allows the simultaneous use of separate boilers and boilers of different capacities.
Advice! Gas heating boilers with a power of no more than 30 kW must be installed in different rooms with individual chimneys and ventilation openings to the street.
Conclusion
When purchasing a gas heating boiler, it is important to take into account personal wishes, as well as professional advice, and entrust the installation of the equipment to a specialist with a work permit. You can’t joke with gas. It is important that the installed boiler has an automatic safety system that will turn off the device in the event of interruptions or damage to the gas supply. The room in which the gas boiler is installed must also be equipped with a special gas analyzer that will turn off the gas supply in the event of a leak. Once a year, the equipment should be inspected by a specialist.
