Variety of outdoor gas-fired boilers

The principle of operation of the device and the cost of heating It depends on the design of the floor of the gas boiler. We offer to meet with the main species and their distinctive features.

Gas equipment has different execution
Gas equipment has different execution

convective

In such devices as energy for heating coolant It uses only the energy of the combustion gas. This significantly reduces the efficiency. However, such models are:

  • easy to install;
  • They have a relatively low cost;
  • characterized by simple design execution.
Convection models have a simple design concept

condensation

Such devices are more expensive traditional convection models. for heating coolant using heat generated during the condensation of the vapor contained in Vents from the flue gas. Have a higher efficiency. Help reduce costs and operate fast enough to recoup the costs for the purchase of heating equipment.

Condensing models feature higher efficiency
Condensing models feature higher efficiency

With boiler

In contrast to the classic heating equipment such devices are used simultaneously for heating and hot water supply. They have two heat exchangers.

The temperature of the water coolant in boiler It is maintained at a predetermined level due to the coil that is inside the tank and used as a heating element. To reduce heat loss from the walls of the boiler are carried out warmth. Hot water circulated through the system from the drive to the last point of demand. As a result, immediately after the opening crane Hot water is supplied to the consumer.

performance specifications

When choosing an appropriate model Gas floor boilers should be guided by a number of characteristics that define its capabilities and ease of use. We offer to meet with the parameters that deserve special attention.

Equipment features depend on the device
Equipment features depend on the device

Power

The parameter that defines the area of ​​heated space. It depends on the structure location. When calculating the required power of the heater for the home, located in the central zone, for each square is taken 1 kW. If you plan to install dual-model, The calculated value is increased by 30%.

Attention! At floor models power is always higher than the wall

Number of circuits

Manufacturers offer:

  • single-circuit model designed exclusively for space heating;
  • combi boilers. Used to connect heating systems and hot water.

Attention! Single circuit units Due to the design are more reliable in operation.

Type combustion chamber

Depending on the principle of operation of the combustion chamber can be divided into:

  • open. For the combustion process uses natural draft. Oxygen is drawn in directly from the air inside the room. This also partly returned products. This places high demands on mounted ventilation system due to the risk of carbon monoxide poisoning;
  • closed. completed fans Forced boost. The combustion process occurs offline. Air is drawn in from outside the home. Combustion products are also output to the outside, which greatly improves the level of security outdoor gas boiler. Chimney may have a different design concept.
Closed combustion chamber is more secure in operation

exchanger Material

To manufacture heat exchangers manufacturers use:

  • cast iron. The product is not afraid of heat-shock and withstands aggressive substances. Able to serve for decades. However, cast iron heat exchangers are brittle. This creates difficulties in transportation and operation of gas boilers floor. Between the return water temperature and the difference must be maintained Me 45 ° C to prevent cracking of the coolant. Also in the cast-iron heat transfer fluids heavy, making it difficult to assembly and disassembly;
  • steel. Heat exchangers are lighter. Not deformed and do not crack. Are smaller as compared with cast-iron, by weight. However, prone to burn-in and corrosion. Able to serve 10 - 15 years. In case of violation of conditions of work service time is reduced;
  • copper. Heat exchangers have a good thermal conductivity. Have a low weight. Corrosion-resistant. Find limited use because of the high cost and rapid wear rate when installed on the floor boilers powerful.
Copper heat exchangers find limited application

Type of ignition and burner

Depending on the design performance of the burner are:

  • single stage. Allow to develop only one power level;
  • two-stage. You can choose one of two levels. Have a longer service life. Presence mode with lower power can reduce operating costs;
  • modulation. Ensure a smooth change of power. As a result, possible to optimize the costs of maintenance of the boiler.
By adjusting the power, it is easier to maintain the temperature

Depending on the design, floor gas boilers can be piezoelectric and electronic ignition. When using the last burner is ignited immediately after turning the boiler on and off after the shutdown.

How to choose the outdoor gas boiler: tips and tricks

Durability and ease of use of heating equipment depends on the performance and functionality of the heating equipment. We offer to meet with the parameters that deserve special attention.

many factors to consider when choosing a

Technical parameters and dimensions

When choosing the heating equipment should focus on:

  • power. It specifies the maximum quadrature heated space and the amount of heated water. When you select a device with plenty of power, you can significantly reduce its service life due to premature wear. When buying a bypass gas boiler to the power needed to heat the room, you should add no more than 25%;
  • exchanger material. Boilers with cast-iron elements have a long service life;
  • fuel consumption. Condensing more economical to operate than convection. Preferably, the presence of an electronic ignition, reducing fuel consumption;
  • the ability to control power consumption;
  • the maximum coolant temperature and heating of hot water. This usually 80 - 90 ° C and 65 ° C, respectively;
  • performance. Current for combi boilers. It depends on the number of people living in the house.

The size and design of heating equipment are selected based on the installation location. Manufacturers offer original design solutions and devices of different sizes.

Advanced Features and capabilities

To increase the level of security of gas heating equipment need to be concerned about the presence of a number of security systems:

  • Gas control systemAllowing disable equipment in the absence of gas flow;
  • overheat protection, Freezing. Especially true when buying equipment for a country house.

Ask a Question

«If you want to arrange hot water, you should choose a model with a dual-circuit "

Level of automation should be paid special attention. The choice will depend on the complexity and purpose of squaring the premises of personal preference. For a country house is enough to get a simple model with mechanical control. For a country house the best option will be the boiler electronically controlled.
