The main criteria for choosing a boiler

The boiler’s economic parameters are influenced by several factors, apart from its fuel consumption characteristic. This relates to the materials, device efficiency, service life, etc.

Material

The parameter of economic efficiency of gas heating boilers has a direct correlation with their service life. Gas units with a heat exchanger made of cast iron are considered the longest in terms of operational life and reliability. These boilers are designed to last up to 50 years. But, the disadvantage of this material is its brittleness, therefore, it is necessary to be very careful when moving it. Only with careful and careful operation can achieve a long service life. In addition to the required caution, it is also important to avoid temperature fluctuations, for example, you can not get cold water on the surface of the heated heat exchanger, as this can lead to the formation of cracks.

Steel-based floor units with steel circuits are less erratic than those with cast iron circuits. However, because of their increased susceptibility to corrosion, they have a shorter service life.

Availability of components

A significant factor influencing the service life is the quality and availability of spare parts. When buying a unit, it is advised to ascertain how simple it is to locate the required parts. It follows that it makes sense that it would be simpler to find the required parts for the more well-known and well-liked brands.

Manufacturers

Regarding country of manufacture, devices made in Germany, Italy, and Slovakia are thought to be the most robust. Comparable domestically made equipment frequently has a shorter lifespan despite being more affordable and better suited to Russian operating conditions.

Routine inspections

Some gas boiler users choose to save money by either not doing routine maintenance or by not calling for help as needed. This is a major error, though, as there are a number of scenarios that can arise when the boiler is operating, such as the burner’s focus changing. Fouling will result from this, and minor malfunctions may follow. Reduced boiler performance and higher gas consumption may result from them if they are not identified and fixed in a timely manner. This is a prime illustration of the need of conducting regular inspections.

Unit efficiency

Efficiency factor is a crucial metric that needs to be prioritized when choosing affordable gas boilers for individual residences.

For instance, the efficiency range for floor gas appliances is 85–90%. Cheaper units come with lower indicators by default and have a burner that operates in one or two stages.

Continuously variable output boilers are thought to be more efficient. The heat exchanger’s heat transfer medium gets heated by the heat produced during fuel combustion. following the chimney’s release of any leftover heat to the atmosphere.

The temperature of the flue gas can be used to calculate the amount of heat lost. A device that reaches temperatures between 100 and 150°C to heat smoke is regarded as an economical unit. The device performs less economically when the temperature is higher than 200°C.

Condensing boilers, with their unique technology for extracting heat from the condensed form, are thought to be the most economically advantageous gas unit for residential use. Boilers that use condensing technology are more than 100% efficient.

Many models with the required economic quality can be identified by considering the different factors that directly impact the economic performance of gas units.

3rd place. Floor standing boilers

Gas boilers that are floor standing are distinguished by their portability and reliable performance. There are benefits specific to this kind of unit. Owing to their design, the devices have a larger capacity than their wall analog counterparts.

Energy-independent models exist that can move without the assistance of a pump and interact with the heating medium either permanently or momentarily.

Automation and additional equipment are rarely found in floor standing boilers. The devices are easier to service in this way.

Under optimal operating conditions, the boiler’s efficiency hovers around 90%. These units do have certain drawbacks, though. For instance, there are requirements that must be fulfilled in order for the boiler to be installed in a separate, specially designed room.

Examine the following three floor-standing gas boiler models, highlighting their respective attributes and features:
