In our time, the cost of energy is constantly growing, and therefore the topic of economy is becoming increasingly important. Competent selection of equipment will constantly save money over the years, so this issue should be given very close attention. In this review, we will look at the most economical heating boilers and analyze which options are best for this or that situation.

Types of equipment

To begin with, it is necessary to consider which options are the most common and what advantages each type has:

Economical heating boilers for solid fuels This option is the most budget in terms of fuel prices. It is cheaper to heat a house with this method, but it also has its drawbacks: the need for periodic maintenance and inspection, permanent bookmarks of firewood or other materials, and cleaning the firebox from ash
Economical electric heating boilers This type is used when the installation of other types of heat generators is impossible or difficult. Due to the fact that the price of electricity is high, such equipment is advisable to use in rooms with a small area and non-constant nature of heating
Diesel heat generators The use of such facilities is limited due to the high fire risk, they require a separate, specially equipped room. At the same time, the cost of fuel increases annually and is quite noticeable.
Gas equipment Many experts are inclined to believe that this option is the most rational from the point of view of reliability and efficiency. That is what we consider in more detail in our article.
Even the most economical electric heating boilers are far less efficient than other options in their efficiency, and this is due to the high price of electricity.

The most important factors to consider when choosing

Savings consist of the following components: the correct choice of the parameters of the device, determining its type and the purchase of a product of a particular brand. Consider some of the points in more detail.

Power

In such a simple system, it is very easy to calculate power: you only need to summarize the performance of all radiators

Considering gas-fired heating boilers, it is impossible not to touch upon such an important issue as the correct calculation of the power of equipment necessary for your home.

This is due to a number of factors:

  • Maximum equipment performance is achieved only when it is operating in the normal mode, which is provided by the manufacturer.

Note! Insufficient power is fraught with constant overloads of the boiler and its operation at the limit of its capabilities, this significantly reduces equipment life. Excessive power will cause a constant overrun of energy resources, and we cannot talk about any savings.

  • The correct calculation allows you to clearly represent the parameters of the system. Usually, the boiler power is calculated by summing the capacities of all the elements included in the heating system, but there is a simpler way: for every 10 meters of a high-quality insulated house should be 1 kW. Another 20% of the reserve is added to the figure, which allows the boiler to cope with even the most severe frosts.
  • It should be noted that the quality of wall insulation and openings has a great impact on energy consumption. Good thermal insulation can save up to 30% of heat, remember this.

Types of equipment

There are three main options. The first of them - floor boilers, the most traditional layout used since the invention of such equipment.

This option can be noted the following features:

Simplicity and durability - the main trump cards of this option.
  • Both maintenance and installation are very easy.. The instructions supplied with the boiler will explain all the main features of the installation and operation.
  • Due to the fact that the heat exchanger is often made of cast iron, the resource of floor boilers is one of the most impressive among all the options.
  • This option has a high power rating., therefore, it is advisable to use it for large buildings.

The second type - wall-mounted boilers, the distribution of which in our days has become very, very wide due to the following reasons:

Compact and attractive - something that immediately catches the eye
  • Easy operation and installation - All work can be easily done by hand.
  • All the necessary elements: expansion tank, circulation pump, automation - are in one case, which allows you to save on the purchase of equipment.
  • Compact dimensions and quiet operation allow you to install the boiler even in the kitchen or in the hallway.

But still the most economical heating boilers are condensing.

Judge for yourself:

The principle of operation of condensing equipment
  • The efficiency of such a heat generator is up to 110%. How is this possible? The fact is that not only the energy of the combustible gas is used, but also the energy of steam released together with the combustion products.
  • The principle of operation of the equipment is simple: in addition to the usual heat exchanger, there is a special coaxial chimney, which causes condensate to fall out and energy is released, hence the high efficiency.
  • The use of such devices requires a very high-quality system for collecting the liquid formed during operation - it is quite aggressive, and the usual sewage system can simply be destroyed.

Note! Condensation boilers can be both floor and wall. It all depends on the required power and the availability of free space.

Conclusion

Even the most economical electric heating boiler is significantly inferior to the condensation equipment on natural gas. This option should be used for best savings. The video presented in this review will help to even better understand the topic.
