Everything you need to know about natural gas boilers

natural gas boilers

In many homes boilers are used to heat water for use in showers or kitchens. It is important to know which boilers are more efficient if we want to save on the electricity bill and make the most of the resources we have. Today we are going to talk about natural gas boilers.

In this post you can learn everything related to this type of boiler. From what they are and how it works to which ones are the most advisable to use, going through the advantages and disadvantages of each. Do you want to know more about it?

What are natural gas boilers?

gas boilers and their calorific value

A natural gas boiler is a container that contains the water to be heated whose fuel is natural gas.

We all want to save the most out of our pocket on household issues to be able to spend it on trips, whims or whatever we want. In addition, with the use of energy we are putting in commitment to the state of the environment. Boilers, like other household equipment, are very important to our lives, since with them we heat the water we use.

Choosing a good model or not depends entirely on a practical knowledge of which boiler is best for our situation. It is important to know which boiler we are going to choose depending on the model, the maintenance it needs, the revisions and the efficiency. If we can choose the one that best suits us, we can save a lot of money at the end of the month. In addition, it must be taken into account that, the higher the efficiency and quality of the boiler, the less we are going to damage the environment with the pollution emitted.

Operation

save on the bill with the boilers

The boilers have a burner that is responsible for the initiation of gas combustion. This gas is normally natural gas, although there are also boilers whose fuel supply is propane or diesel. When the gas is heated, it turns the water contained within the tank into steam and exits through the circuits to heat the rest of the home. This water vapor can be used to connect them to radiators or even underfloor heating.

Propane boilers need another tank to store the gas, so we are occupying more space than we would like to dedicate to this type of equipment. The diesel ones are cheaper and it also allows us to cook. In addition, it requires an outlet for the gases generated during combustion, so they also need more installation.

All these needs make installing such a boiler more time consuming and ultimately more expensive. For this reason, natural gas boilers are the safest and most practical. The concept of natural gas is so widespread and so widely used that it is known as Gas city.

Types of natural gas boilers

There are different types of natural gas boilers and, as mentioned before, we must know well which of them to choose to optimize our resources well to, after all, save money.

Watertight gas boilers

sealed boiler

These boilers have a sealed combustion chamber and do not consume air from inside the home. This feature makes them safer, since the gases produced during combustion do not come into contact with the air we breathe.

Low NOx gas boilers

Nitrogen oxides are polluting compounds that are generated during the combustion process with excess oxygen. Boilers that do not have any type of emission regulation are more polluting and less efficient. This type of boiler has a design similar to the previous one but it is prepared to emit less nitrogen oxides.

Condensing gas boilers

condensation gas

They also keep the model like gas tight, but have the advantage of reusing the energy of water vapor over and over again. That is, they have a circuit that redirects used water vapor to, in turn, help heat the rest of the water in the tank. This reduces the total cost of the energy used to heat the water, since it takes advantage of the residual heat of the steam generated.

They are also safer and more efficient and we can save a lot of money on natural gas consumption.

Atmospheric gas boilers

atmospheric gas boilers

In this model of boilers, unlike in the previous ones, the combustion chamber is open and the air used to heat the water is collected from the place where the boiler is located. These boilers pollute much more and are less efficient and safe. In addition, they divert some harmful gases into our home.

Pricing

price of natural gas boilers

Talking about general prices is somewhat complicated, since there are thousands of models of each type. However, atmospheric boilers (although they are the least recommended) are the cheapest. Its price is around 300 euros. Lower quality, lower price. But not for that, we should opt for these. We will be polluting more and spending more gas in the long run as its efficiency is lower.

On the other hand, watertight boilers have a variable price between 400 and 1400 euros. They have a much more expensive initial price, but being less polluting and more efficient, in the long run, it will mean less gas consumption and, therefore, less cost.

Advantages of gas boilers

advantages of natural gas boilers

Using gas boilers has its advantages and they are the following:

  • Its price is usually cheap (from 300 euros). It can be had at home.
  • Its effect to heat water it is quite fast and comfortable. In addition, as it has a thermostat and a counter, it can be programmed to heat to the temperature we want.
  • They do not usually take up much space and have a lifespan of many years.
  • It hardly needs cleaning compared to other heating means and it does not emit noise.

Disadvantages

boiler maintenance

Finally, it is also important to name the disadvantages of this type of boiler. The only apparent disadvantage is its maintenance. They must be cleaned once a year to avoid breakdowns and jams and, above all, to prevent accidents.

With this information you can choose which type of boiler is best for you and save as much as possible on heating.
