Gas Boilers

This article is aimed at those readers who are going to build a house or make some changes which are related to heating and water heating. Usually, such people have several options for heating the house, but many of them stop at gas boilers because it is practical and cheap.

By reading this article you will learn more about gas boilers. This will help you to make the right choice when purchasing one. So, let's start!

One of the crucial issues which you must resolve when arranging a private heating system is the right choice of a gas boiler. It is because the level of comfort of your family will directly depend on it in the future. There are a lot of boiler models with different functions and purposes of use. Therefore, if you decide to buy a gas heating boiler, it is worth exploring the main features of this equipment in detail.

What information will help to make the correct choice?

First of all, you should find out for yourself the main points that will facilitate your further choice before you go to the store or open the online store. Decide what functionality you need - high efficiency, ease of use, or maximum savings. Make a list of the main requirements. It will help you to choose the right boiler model.

Variety of boiler equipment in terms of fuel combustion efficiency

The amount of money you pay for gas consumption depends on the energy efficiency of boiler equipment. There are three boilers according to the energy efficiency parameter:

  • Condensation boiler
  • Convection
  • Parapet

In condensation devices, the heat exchanger is heated by the combustion of gas and heating steam, which goes along with the flue gases. Such heat transfer is possible due to steam condensation on the walls of the heat exchanger.

In a convection gas boiler, gas does not condense, so the energy for heating comes only from the burning of gas masses.

Parapet units on the principle of heating are similar to convection. The design allows you to operate them as a radiator.

Before choosing a gas boiler, take a look at the condensing heating devices - they are more energy efficient (up to 20%), compared to other types of models.

Working circuit

Boilers are two-circuit and with one working circuit. There is only one difference between the units: the single-circuit principle of operation heats only the room while devices with several circuits can also provide water heating.

Traction and the combustion chamber

This parameter determines how carbon dioxide (waste combustion) is removed from the system. You can find boilers with forced pitch as well as aggregates with natural pitch. The last belong to the classic version, which is installed in well-ventilated areas with the ability to connect to the chimney. Such boilers have a closed working chamber.

Forced removal of waste gas combustion occurs through the built-in ventilator which expels smoke through a special exhaust. If the ventilation in your home is good and you have a chimney, you can safely install the equipment with a natural draft. For units with a forced exhaust system, an open-type combustion chamber is required.

Heating element

The heat exchanger is responsible for heating the circulating fluid; therefore, the energy efficiency of the entire power system depends on it. All existing devices according to the heat exchange element can be divided into 5 types:

  • With a steel heat exchanger
  • With aluminum heating elements
  • With a copper heat exchanger
  • With a stainless-steel heater
  • With cast iron element

Units with steel heat exchangers are among the most popular. This is thanks to the cheapness of the material and its good ductility.

Take into account these 4 main positions and you will find an appropriate gas boiler!
