Varieties and features of gas boilers for heating

A gas boiler for heating and hot water supply is an integral part of a private house and many city apartments. Independence from utilities and the availability of blue fuel made this equipment the most in demand in solving the issue of heating during individual and capital construction. The modern market is saturated with gas heaters of various designs, types and sizes. In order not to be mistaken in the choice, you should familiarize yourself with the assortment of goods on sale, study its features, capabilities, pros and cons, installation and operation rules.

Selection criteria for gas boilers

Varieties of gas boilers for heating and hot water supply

In order to choose the right gas boiler for heating for an apartment, it is necessary to have initial data, under which the technical and other characteristics of the product will be adjusted.

When deciding on the purchase of gas equipment, one should be guided by the following criteria:

  • Power. It is measured in kW. For efficient heating of the room, the optimal figure is 10 kW / m². The ability to heat a volume of water to the desired temperature corresponds to 15 kW / 100 l.
  • Combustion chamber type. Modern parapet ovens with a closed chamber take oxygen from the street through a coaxial pipe, thereby maintaining an optimal microclimate in the room.
  • Mounting option. Wall mounted appliances are compact and lightweight, but have limited functionality. Floor standing boilers are more powerful and reliable. They require more free space and a solid foundation.
  • The number of contours. Determines the breadth of the spectrum of equipment application.
  • Life time. Determined by the materials from which the work equipment is made. The most durable are cast iron parts, followed by stainless steel. The fastest burning out and destroyed by corrosion is black iron.
  • Additional options. The number of control and monitoring devices affects the cost of the product, but makes its operation more efficient and safe.

The price of the goods plays an important role in the choice. This indicator does not always determine the level of quality. Domestic products are not inferior to European counterparts, but they are much cheaper. It is advisable to choose a Russian boiler with imported electronic parts.

Operating costs

The main parameter for choosing gas equipment is the type of burner and the presence of a chimney

The gas boiler in the apartment is an excellent alternative to central heating and hot water supply. Modern technologies make it possible to make heating devices more and more compact, more efficient and safer. At the same time, the production of heat energy involves associated costs.

The operation of the boiler is associated with the following costs:

  • Purchase of equipment. Even budget models have a pretty high price tag.
  • Purchase, installation of piping and radiators. It is possible to reduce costs by using reinforced polypropylene pipes for construction, which are several times cheaper than their iron and brass counterparts.
  • Obtaining permits. It should be borne in mind that it is forbidden to carry the boiler on your own after its installation.
  • Gas. Raw materials are inexpensive, but a considerable amount will run up during the heating season, especially in a harsh winter.
  • Periodic checks by regulatory authorities. All gas services, including meter calibration, are paid.
  • Replacement of worn parts (burner, sensors, chimney).

The equipment pays for itself in 5-10 years, depending on the conditions of its operation and the prices for utilities in the region. The main advantage of the autonomous system is that it can be turned on, off, added and reduced temperature depending on the wishes of the owner of the property at any time of the year.

Classification and differences of gas boilers

A double-circuit boiler heats the room and at the same time heats the water

Before installing a gas hot water boiler at home, you should familiarize yourself with the designs and differences of the devices on the market.

The equipment is subdivided into the following types:

  • Single-circuit. The products have one heat exchanger designed to heat water exclusively for the heating system. The devices are used to equip small-area facilities, sometimes non-residential. The movement of fluid through the system is carried out by gravity or under the action of a pump. The price of such products is much less than that of more complex devices.
  • Double-circuit. Such boilers are installed in private mansions and apartments in multi-storey buildings. The units are distinguished by their large dimensions and high power. Designed for heating and providing facilities with hot water for domestic purposes. Moreover, both systems are independent and can equally efficiently simultaneously perform their tasks. Water supply to the taps is carried out from tanks or a flow-through heating circuit. As a minus, the increased fuel consumption and the need to allocate space can be considered, since double-circuit boilers are made in floor-standing design and have rather large dimensions.
  • With natural traction. Boilers of this type have an open combustion chamber and a separate chimney. During the operation of the burner, air is taken from the room, and the combustion products are removed due to the difference in temperature and pressure inside and outside the room. Natural draft stoves are not as effective; if the rules for installing and maintaining the chimney are violated, they pose a danger in terms of carbon monoxide poisoning.
  • Forced traction. The boilers are equipped with a closed-type firebox, which completely excludes any contact of fire and combustion products with the room. The devices are equipped with coaxial pipes through which clean air enters at the same time and toxic gases are removed. To increase safety and efficiency, the furnaces are equipped with fans. One of them injects clean air, and the second draws the combustion products into the pipe. The advantage of such a system is that ventilation continues after the boiler is turned off. This ensures that gas is removed from the furnace in the event of an emergency leak.
  • With automation. The installation of precision electronic devices makes it possible to customize many parameters. With modern models, the start and stop times, the room temperature mode throughout the day, emergency shutdown and alarm sensors are set. Remote redundant control panels can be carried throughout the house, there is no need to go to the boiler every time to set it up.

The choice of the optimal design is easy to do. It is necessary to prioritize and find a product that meets their criteria. Chasing cheapness is not worth it. The lower the price, the lower the quality of the product, the more often it will have to be repaired.
