How to choose a gas boiler: recommendations

At the moment there are different gas boilers. Which one to choose depends on a number of factors that every consumer should know about.

What are the models?

By the type of performance, there are wall and floorsolutions. Speaking about how to choose a gas boiler, it is worth noting that they are one- and two-circuit. It is also accepted to distinguish these devices by the type of material from which the heat exchanger is made (this is steel or cast iron), as well as the type of burners.

Before choosing a gas boiler, it is worthAssess the quality of water in your running water. If it is a hard substance with a considerable amount of iron, then you can recommend a device with a built-in boiler. It is important to note that in this situation we are talking about a steel container with water, in which there is a coil with a coolant passing through it. It turns out that the liquid from the heating system gives its heat to the water in the boiler. This choice of boilers is due to the fact that calcium and iron settle on the heat exchangers much longer. Over time, the coating of the coil is covered with a layer of scale, which causes the water to heat up longer, and the heat transfer and the productivity of the heating system gradually decrease. These processes are not as intense as in flow-through heat exchangers.

If we talk about how to choose a gas boiler,it is impossible not to mention the two-circuit solutions with an integrated flow-through plate heat exchanger. It can not be called a better option, since the internal surfaces of such a container quickly overgrow with a scale that clogs the flow channels, and this reduces the heat and water flow. During the use of the device, the temperature of the water becomes unstable, as well as its wave-like changes, vibration and noise appear. All this becomes the reason for the need for premature repair of the device.

Talking about how to choose a gas boiler,that in a residential house the best option would be to use the appliance with a boiler. In this case, switching from heating to hot water supply will be much less, but this factor has a strong influence on the service life of the device.

Gas boilers: how to choose?

First of all, the buyer faceschoice of manufacturer. It is better that it was some famous brand, otherwise it is difficult to count on quality. The next important point is the choice of equipment according to its characteristics. Here you can stop at an affordable device that will spend a lot of fuel, or prefer a more expensive model that pays off due to the economy in operation. The final step in the selection involves determining the appropriate power of the device. It is better to calculate it even at the stage of building a house, but for a ready home, you can also determine it. Usually ten square meters of space requires 1 kilowatt of energy. If it is necessary to heat the water, another 25% should be added to this indicator.

In conclusion, it is worth mentioning about the most popular brands of this equipment, such manufacturers as Electrolux, Ariston, and Gorenie.
