How to Choose Best Boilers?

If you are entirely fasting on the subject, it is more than the right to deal with professionals, but, as you will find out by reading this guide, you can easily acquire some elements of evaluation and, perhaps, choose the system that is right for you directly on the Net.

What Is a Condensing Boiler?

The furnaces burn a fuel (diesel oil or, better, gas), extract heat from the gases resulting from combustion, transmit it to the water circulating in the radiators, through a “heat exchanger, to increase the temperature of our home.

However, condensing boilers can condense a more significant percentage of the steam in the combustion gases, making the whole process more efficient, economical, and, in conclusion, more environmentally friendly.

As mentioned in the introduction, since September 2015, the Erp legislation has effectively delivered the market to condensing boilers, making them an obligatory choice.

In some exceptional cases, it is still possible to install open chamber models, for example, in replacement in environments not compatible with condensing boilers. The incompatibility, however, must be certified by a qualified technician, and the chosen product must still comply with some legal parameters.

The Right Choice

To choose which condensing boiler to buy, it is necessary to make more than one evaluation. First, we need to understand how much power we need. This largely depends on the cubic meters to be heated and on the number of people who live in the house and their lifestyle. The boilers, in fact, can be used for heating the home, but also for water, or only for sanitary water, that is, that used for personal hygiene.

Usually, 24 Watt indicates a power more than adequate for about 100 square meters, for a medium-sized family. Of course, the house should be adequately insulated, with double glazed windows and proper insulation. Furthermore, even the geographical location can have its weight: it is not the same if you live more than a thousand meters above sea level or on the coasts of Sardinia.

As you will read in the reviews, many models adapt to be installed both outside and inside. Outdoor installations, in general, must have a niche that protects from the weather and, of course, we must keep an eye on the risks caused by the lower temperatures.

The costs on the market can vary, from low prices of around 500 or 600 euros to figures above one thousand euros. The differences concern both the quality of the hydraulic and mechanical material and the electronic component.

Therefore the possibility of controlling and programming, utilizing applications on a mobile phone or another mobile device, the operation, and activity of the boiler.

Made in Italy, enthusiasts can be happy: many national companies are successfully engaged in this market. Ariston, Baxi, Immergas, Beretta, are some of the best known and best selling brands in the sector.

The Economic Evaluation

To choose an excellent condensing boiler it is essential to consider its cost, which cannot be limited to the starting price. Also, for this reason, it is particularly important to evaluate where to buy and from whom. Even Amazon allows you to get in touch with companies that deal with the essential after-sales operations.

First of all, you likely need an installation, which includes the first ignition, the testing, and the first smoke control. It is not at all evident that everything is included in the purchase price. Also, you may decide to add the extended warranty and scheduled support.

The costs vary greatly depending on the company you rely on, but, in general, you can expect a price between 50 and 90 euros to be paid once, to which is added an annual fee that usually is around 100 euros.

If you multiply these figures by 4 or 5 years, i.e., the warranty extension period you have chosen, you get a number ranging from 500 to 700 euros. Should it?

Unlikely, if we consider that a boiler should not need extraordinary interventions in the first years of activity and that the smoke controls foreseen by the law should not be more than two (at most) in the period considered.

Furthermore, with the same kW produced, it would always be better to opt for a natural gas boiler than an LPG boiler. The combustion and heat recovery process is much more efficient.

Even with the new boiler are you cold at night in winter? Sometimes a good and warm quilt solves the problem!
