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, wall and floor solutions are singled out. 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 worth to assess the quality of water in your water supply. If we are talking about a hard substance with a considerable proportion of iron, then we 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 do not occur as intensively 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 the best option, as the internal surfaces of such a container quickly overgrow with a scale that clogs the flow channels, and this reduces heat and water flow. During the use of the device, the water temperature 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.

Speaking about how to choose a gas boiler, we note that in the residential house the best option is to use the appliance with the 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 faces a choice of the 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 stay 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 also Gorenie.
