How to choose a boiler for the home

In condensing boilers, the water is nebulized within the system in order to humidify the air that circulates through the boiler. The end result is that the suspended water particles become very fine droplets and settle on the heat exchanger tubes, where most of the heat transfer process takes place.

The gas burns at a lower temperature, with greater energy use of the heat, saving gas (up to 18%). In addition, smoke losses through the combustion gas outlet system are considerably reduced, expelling low NOx smoke. Their advantages are that they are safe and very efficient, but they have the disadvantage that they need a nearby drain to pour out the condensed water, so their installation is also more complex.

Key advantages of condensing boilers:

• Higher Efficiency – As mentioned, condensing boilers are much more efficient than older models. They are designed to get the most out of the fuel used, resulting in a much lower total cost of ownership.

• Space saving: another great advantage is that they do not require as much space as traditional boilers. Due to their compact design, they can easily fit into small places, freeing up valuable space in your home or office.

• Less Waste – Another way they help the environment is to reduce overall waste due to their high efficiency. Some people have even reported a significant drop in their household waste after installing a new condensing boiler.

• Easy maintenance: they do not require much attention or constant maintenance due to their simplified design. In fact, most homeowners report only a slight increase in their annual bill for professional services after the initial installation.

Many times we ask ourselves how to choose a boiler? What is the best brand of condensing boilers? It can hardly be said that there is a single brand of condensing boilers that is the best of all. That there is a better brand is a fairly relative issue. This must be seen in relation to the needs of the family in terms of:

• Number of inhabitants of the house.

• Number of services that the boiler will provide.

• Type of fuel with which it works.

• Availability of said fuel where you live.

• Hardness of the water in the region.

• Flow of water entering your house.

• Inter alia.

Based on all this, each house must choose which is the best boiler for itself. However, keep in mind that, according to a comparison of condensing boilers carried out by the OCU (Organization of Consumers and Users), the best condensing boilers for the 2020-2021 period in Spain were from the Cointra brand. Vaillant, Junkers, Baxi and Ferroli also obtained very good marks.

The OCU (Organization of Consumers and Users) is a Spanish organization that aims to defend the rights of consumers. The information it publishes about the products on the market is almost always of great practical use.

Now we will see the top 10 condensing boilers according to the OCU for the period 2020-2021 in Spain. These results have been taken from the comparison of condensing boilers carried out by said organization and published in its October 2020 magazine.
