Boilers are in many homes, and gas boilers are one of the most recurrent types of boilers without any doubt, so knowing how to operate these types of boilers is very important.
Before making a specific approach to gas boilers, we will make a general approach to boilers in general, so it is interesting to make a general mention to all types of existing boilers because this is what allows us to make a complete approach global and then enter into the particular reality of gas boilers.
Types of gas boilers
When we talk about a gas boiler, we are only talking about a specific boiler reality, and this is true because there are many types of boilers and many types of boilers that can be divided not into a single kind of boiler but in a large variety and sub-variety of existing boilers.
The boilers can be distinguished by the type of energy they use to operate; they can also be identified by the specific technology they use and by many more variables that can be taken into consideration, in the following lines we are going to talk about some of the main ones. Within this whole exhibition, you will see how a gas boiler works.
So, first of all, we can talk about, for example, the boilers designed to give heating uses that work through the internal circulation of hot water, it is this flow of hot water that allows the radiators to be fed and to heat the same with the hot water that passes through the tubes that transport it.
Once the hot water reaches the radiators, they heat up and act as great heat sinks that provide the comfort level to the room. The mechanism is simple: the water reaches the hot radiator, the same heat up, and the water cools, then it returns to the boiler where it returns to temperature and returns to start the flow to the radiators and thus in a constant way.
Boilers according to the type of energy they use
In the previous exhibition, it is seen how a gas boiler can work, since what is specified serves both those boilers that can be operated with diesel, as well as those that can work with propane or natural gas, among other energy sources. It is at this point that we can correctly visualize that there are different types of boilers according to the kind of energy they use and that there are even boilers that use different types of gas to work.
If we want to divide the boilers into groups we can do it basically in two groups, on the one hand, we can talk about the boilers and, on the other hand, we can be talking about the atmospheric boilers.
When we talk about these two large boiler groups, we are talking about two types of boiler that diverge significantly at one point: the way to receive the air that must allow combustion and the exit of the gases once the combustion process has been carried out.
In the first place, we will enter into the very conception of atmospheric boilers since they are the best known since they take many more years between us and have effortless operation. Currently, they are in apparent retreat because legally cannot be installed inside the home in enclosed spaces and provided that the right conditions are not given so that they can be installed since they receive an evident influence from external conditions and do not have watertight compartments are more insecure than watertight boilers.
The watertight boilers have a concentric tube that allows the gases to escape safely, they are not affected by environmental issues and by almost any other external factor, and they can be installed inside the home without any inconvenience.
Then we could talk about the binomial existing between the so-called pure boilers and boilers of a mixed character; the former has a direct orientation to serve as heating elements while the latter are suppliers of DHW, that is, hot water.
In another order of things, we could talk about the so-called accumulation boilers and those called micro-accumulation. The accumulation boilers are classic boilers that are around 50 liters and can keep the water always hot inside its storage tank.
This type of boilers can provide hot water always. With a high level of flow, on the contrary, those of micro-accumulation have the great advantage of avoiding draft changes in the water temperature in its start, avoiding roasted the dreaded cold-heat effect when the tap is turned on. A whole stream of waterfalls on it before it warms up, and the desired comfort temperature is obtained; this also applies – of course, to the gas boiler.
There are also NOX low-emission boilers; that is, they make a significant reduction in the nitrous oxides pollutant emissions of other boilers, and then there are so-called condensing boilers that allow a high-performance system to be obtained thanks to the level of recovery of heat that they incorporate.
Gas boilers for heating in concrete
Speaking of the gas boiler says explicitly that it was based on a functioning based on a burner that is responsible for promoting the combustion of gas within the system.
As we have seen before, some boilers work with different types of gases, although at present, we can say that the vast majority of gas boilers work with the aforementioned natural gas.
The gas boilers have the function of burning the fuel that feeds them, heating the water, and converting it into steam so that it makes the circuit that has been seen with previous paragraphs.
It should be noted that the boilers that work with propane gas have a slightly different operation and that those that work with diesel are not suitable for cooking at the same time as they have different gas output needs than the others.
Speaking of the prices of a gas boiler say that they are very different (because logically depend on the specific features, the brands and models that want to buy and a long list of variables that can be mentioned) but have the characteristic enough common to be a boiler of a reasonably economic nature so that the fork can be between three hundred euros and less than two thousand euros, but as we say it is very general, is an extensive range and all this is merely indicative.
So the price can be one of the advantages of a gas boiler, but it is certainly not the only advantage that gas boilers have. The gas boilers also have the advantage of being very easy to install, they occupy little space, they are very comfortable to be used, and they are very fast in their operation.
Another of the significant advantages of a gas boiler is that they tend to be very durable, the life of the gas boilers is usually quite high, and this is very important if you add the low price of these already before mentioned above implies a full amortization of its cost.
The ease of cleaning is also another feature that makes gas boilers stand out; in this case, it can be individually and referred explicitly to pots that are powered by natural gas.
But, obviously, like everything that has its face, there is also a counterpart, everything that has its advantages also has its disadvantages. Although in the case of gas boilers, the benefits greatly outweigh the disadvantages Of these, of course, they also have some problems and should not be mentioned.
The main disadvantage of a gas boiler is not a particular disadvantage of this type of furnace. Still, it can be mentioned as a relevant aspect because these boilers are suitable for this: gas boilers require Periodic maintenance, and the same cannot be every many years.
Specifically, a gas boiler should be revised (and revised means clean and “tuning”) at least once a year because it will prevent possible problems and even extend its useful life. Also, it is worth mentioning the need to purge the radiators, another reality that is not unique only of this type of boilers, but that should be said.
