Operation of gas boilers for heating of private houses has a sufficiently large number of positive aspects. These include: price of the energy resource available for a wide range of consumers the cost of equipment, intuitive and fast installation, high energy efficiency. It is also important to note the fact that using natural gas boiler, completely eliminates the need for firewood and the furnace is very time-consuming.
Even if installation of heating gas is carried out by skilled workers, the choice of this unit is always carried out by the owners of a private home. Taking into consideration a large selection of gas boilers, choose a suitable option for themselves it is hard to do.
Not to get confused and make the right purchase, you are requested to examine the main types and technical characteristics of household gas devices on the market.
Benefits of gas boilers ↑
In the domestic market of gas heating boilers are the most common technical equipment. Primarily this is due to the relatively low cost of natural resource, and its availability in territorial terms.
It is also worth noting that the boilers for heating of private houses have a number of positive characteristics that distinguish them from units operating on alternative fuels.
The advantages of gas boilers:
- The ability of the device operation in automatic mode, without human control.
- The compact Assembly of the device and its attractive appearance.
- Reasonable cost of equipment.
- The reliability and longevity of use.
- Acceptable price per unit of energy produced by the boiler.
Typically, devices operating on natural gas, are divided into two groups:
- Classic type. The operation of such units are characterized by low heat of combustion, in which part of the energy produced goes together with the water gas entering into the composition of combustion products.
- Condensing type. The principle of operation of the boilers based on the heat energy released during condensation of water vapor. This type of equipment is very economical. Its efficiency, in comparison with the classic options of heating devices is higher by about 10%.
No matter what type boiler, it can be mounted on the wall and on the floor. All heating appliances operating on natural gas, can be single circuit, ensuring only the heating and Combi, which can not only raise the temperature indoors, but also to ensure uninterrupted supply of hot water.
All gas boilers for home heating can have in its complete open or closed combustion chamber, classical or coaxial flue.
Operation of gas boilers to heat the home became the best alternative to solid fuel or electric heating devices.
A large part of the mini boiler-suited to work on gas. Manufacturers offer a choice of a large number of models of heating appliances. Their modification depends on the source of energy – gas natural or liquefied gas.
Classification at the place of installation ↑
Types of gas heating appliances in great variety. Depending on the location and method of installation are the following types: floor, wall, and parapet.
Outdoor devices ↑
Heating devices of this type is the classical model of gas boilers with a very large capacity. Typically, they are used for space heating rather large areas (industrial or public buildings). In addition to the heating function is such boilers, if necessary, heat the water and for human needs and for the functioning of the water floor. This design of the device provides for two-circuit heating system. In such units can weigh up to 100 kg, because the heat exchanger is traditionally made from cast iron or steel.
The room in which outdoor boiler will be mounted in order to fire safety shall be equipped with exterior door, width 80-90 cm. the Door should open outwards.
Also, it is very important that outdoor gas appliances must be installed and connected to the gas line only professionals who have the authorization for this activity.
Wall-mounted gas appliances ↑
This type of boiler appeared on the market recently, and very quickly acquired a wide circulation. This popularity is due to attractive appearance, small size, allowing to arrange the heating appliance in the kitchen and any other not very spacious rooms.
Despite the fact that the boiler of this type are quite small in size, it includes all the basic functions inherent in outdoor units. The only thing that distinguishes this type of boilers – they are not very large capacity.
Compact and beautiful to look at the body of the instrument hides for his cover of the gas burner, the expansion side, the pump, circulates coolant and many other elements that allow you to maximize the use of wall-mounted gas boiler.
It is important to note that, despite its small size, this heater successfully heats the room, but also heats the water. The management of these boilers is automatic, allowing to minimize the human impact on the operation of the boiler. It is sufficient to set the parameters of temperature. Safety explication provides a special sensor that will shut off the device when the interruption of gas supply, and will resume works of the boiler, when the gas goes up again.
Parapet boilers ↑
These heating devices are also called bendikovym boilers. For installation of the heater parapet type does not need a chimney because all combustion products are discharged by means of special coaxial flue.
Boilers of this type can be installed in any area of the house. Typically, they are used for heating small country houses or apartments. Despite its small capacity, this device is able to provide not only a comfortable temperature, but also continuous hot water.
The main feature of parapet boilers is that the heating and hot water can be connected with different sides of the Central gas pipeline. This design feature of the heat exchanger allows you to connect the boilers even in very confined spaces.
Classification by functionality ↑
Buying a boiler, a homeowner must clearly define the purposes for which he needed this device. Perhaps in addition to warm air will demand water heating function.
Single-loop heating devices do well with just one function, or the supply of heat or hot water. But this problem is well solved by installing an electric boiler for domestic use. By choosing this system to ensure a warm home and an uninterrupted hot water you need to understand that it will take a large cash investment.
Choosing a Combi gas boiler can simultaneously solve two problems: to heat the house and heat water for personal needs. It is also worth noting that such devices take up less space, and the acquisition of single boiler dual type, do much cheaper than buying a gas boiler and a.
The heating appliance with dual system can operate in the mode of flow of heat, or to have internal, built-in boiler. Last option is the most preferable for a large family, when significantly increases water consumption.
Depending on power, gas heating boilers are divided into single-stage and two-stage.
Single-stage type of boiler operates on a single power level, which is not very efficiently consumed gas. Given the fact that the private house is heated no more than five months in a year, not always demand full power equipment.
Two-stage heating is more economical in this respect.
Their device allows you to:
- self-adjusting brush up of gas;
- to save the consumption of energy;
- to reduce the frequency of inclusions of the boiler, which increases the operating life of the device, and restricts the entry of harmful substances into the environment.
Two-stage heating devices, usually equipped with smooth switches gas consumption modulation. This feature allows you to save the consumption of energy and simultaneously use the boiler and water heater with different capacity installed separately.
Conclusion ↑
By purchasing gas Central heating boiler, it is important to consider not only personal needs but also expert advice and equipment installation to professionals with a work permit. Gas trifled with. It is important to mount the boiler had an automatic safety system that will shut down the device in case of interruption of gas supply or damage. Also in the room where will be installed a gas boiler installed a special sensor that will stop the flow of gas in case of leakage. Once a year the equipment should be inspected professionals.
