When choosing the boiler for your home, it is essential to choose among the latest generation models. This not only for an aesthetic reason or to have a highly technological boiler, but above all because modern boilers guarantee greater energy savings and greater respect for the environment. Not only that: focusing on a boiler that guarantees greater energy efficiency, allows you to enter the costs related to the purchase and installation of the same, within the relative items for the request for incentives for restructuring.

The purchase of a boiler, in fact, is usually carried out either due to a failure of the old model or due to the need for modernization of the heating systems during the renovation of the apartment in which you already live or in which you are about to move. These works are part of the incentives that the Italian State pays every year to citizens who aim for the energy improvement of their apartments. We will see later and in greater detail what are the possibilities of using what is defined Ecobonus.

To understand the reasons that can lead to the purchase of a boiler and, above all, to understand the choices that suggest to focus on one model rather than another, it is first necessary to understand some important points on the world of boilers, on the models available on the market, on the importance of the energy efficiency of the boilers themselves and, above all, on the possibility of receiving those incentives for the renovation of heating systems and, therefore, for the installation of the boilers.

The different types of boilers

When talking about the boiler, different models can be considered, which vary according to the operating modes. The older type boilers, which are less and less used today, are open chamber boilers. They are not fully compatible with the current safety and energy efficiency standards and are therefore less and less used and it can be said that, presumably, they will disappear from the market within a few years. Their operation is based on the combustion of the oxygen present in the room where the boiler is located and for this reason they cannot be used indoors, but only outdoors. The combustion of oxygen, in fact, leads to the formation of carbon monoxide, a lethal gas in closed environments and without air recirculation.

In most cases, sealed chamber boilers are now used. These can be with a standard sealed chamber or with a sealed condensation chamber. The former are certainly the most used in apartments, both for their versatility and for their size and, again, for their good energy efficiency. Combustion takes place inside a sealed chamber and this makes these boilers safer than those with an open chamber, although their installation in ventilated rooms is always recommended.

The sealed chamber condensing boilers represent the most modern solution and, above all, the most economical one, especially for those who use the boiler both to heat water and for the domestic heating system. These particular boilers allow the reuse of the condensate of the exhaust fumes ensuring a minimum dispersion of the same, guaranteeing respect for the environment and, at the same time, greater energy efficiency.

Choosing this type of boiler is essential when you intend to carry out work that points to complete energy restructuring, that is, which have the purpose not only to change the boiler, but to renew the entire heating system. Condensing boilers, in fact, guarantee greater efficiency when associated with particular types of radiators.

Overhaul of the boiler and efficiency

When we talk about the boiler and energy efficiency we cannot disregard talking about the revision. The boiler overhaul is mandatory not only for safety reasons, but also to always guarantee the maximum energy efficiency of the boiler itself.

The overhaul, regardless of the boiler model, can only be carried out by qualified personnel, that is, who has the necessary certifications to carry out all the different procedures that guarantee the verification of the fumes and the correct functioning of the circuits, filters and various mechanisms. Depending on the type of boiler, i.e. depending on the model, age and power, the overhaul must be carried out every year or every two years.revision-verification-fumes-boiler

When it comes to maintenance, overhaul and smoke inspection, care must be taken not to confuse the different procedures. Maintenance, in fact, consists of a series of procedures that allow you to clean the burner, to check the correct functioning and cleaning of the regulation exchanger and to ensure the efficiency of the flue gas discharge.

The verification of the fumes, on the other hand, is a real chemical control of the composition of the gases emitted by the boiler, focused in particular on the concentration of carbon monoxide. Furthermore, by checking the fumes, it is also possible to obtain information on the boiler efficiency and on the smoke index, a parameter that indicates the volumes and types of fumes emitted. To get the best performance from your boiler it is necessary to keep the emissions of carbon gases, i.e. carbon monoxide and carbon dioxide, below a certain value, which varies according to the type and power of the boiler. These values ​​can be requested from the maintenance technicians and are also reported in the boiler manual.

The booklet is mandatory and must be completed for each type of intervention that is carried out on the boiler, from the date of first installation to routine maintenance, from the replacement of faulty parts to the smoke check, etc. The compilation must necessarily be carried out by authorized technicians. Furthermore, the data of the appliance, in particular the serial number, and the owner's data must be reported in the booklet. Furthermore, as already mentioned, all the interventions that are carried out on the boiler must be reported, whether they are those relating to routine maintenance, to checking the fumes or to changing faulty parts.

Fume review and verification: how to choose an efficient boiler for safe savings

As already mentioned, choosing the right boiler is essential to ensure respect for the environment and energy savings. For this reason, state incentives are guaranteed every year for those who carry out work in the house aimed at improving the energy efficiency of the apartment, namely the purchase of a boiler and the renovation of the heating system.

For 2017, the tax deductions for those who carry out modernization work on the home heating system can cover up to 65% of the expenses incurred. In particular, these concessions, known as Ecobonus, are aimed precisely at improving energy efficiency, to be carried out through renovation of the apartment, for an increasingly green and conscious use of energy in all its forms. The incentives for the renovation they can be used as long as a modern boiler is chosen, even more so if it is a condensing model: in case of replacement of an old open chamber boiler with another of the same type, however, you will not be able to enjoy the Ecobonus.

It should also be emphasized that in the case of costs for heating systems and for the installation of a new boiler, the maximum deductible expense is 30 thousand euros. Furthermore, it is essential that the works are carried out by qualified companies and that all data relating to the boiler (or the new plant) are transmitted to ENEA for the control and verification of energy requirements.

But what are the boiler models that guarantee safe savings and therefore allow you to improve energy efficiency? As already mentioned, the boilers that best meet these characteristics are modern condensing boilers. Furthermore, these models also have temperature ranges that ensure further savings on gas consumption: in particular, for temperatures below 45-50 ° C, bill savings of up to 20% can be achieved compared to old systems.

To make sure you are using the most convenient temperatures, modern boilers have an indicator that lets you know which temperatures are set, so you can always select the ranges that fall within the eco settings. In this way it becomes easy to choose the most suitable values ​​to have the right water and heating temperatures and, at the same time, ensure savings on the bill and less gas emission from the boiler with consequent improvement of the external environment.

A further saving is then guaranteed by the use of modern radiators and heating panels, more compatible with condensing boilers, because they are able to guarantee high heating of the apartment even using fluids with lower temperatures.

Finally, to ensure constant savings over time, it is very important that the boilers always operate to perfection, ie regular maintenance is required. A properly maintained boiler can maintain its energy efficiency unaltered even up to 15-20 years.revision-verification-fumes-boiler-maintenance

Of course, maintenance costs are between 150 and 250 euros, depending on the boilers and companies. This figure includes both routine maintenance (between 60 and 80 euros) and control of smoke emission. These operations, as already explained, must be carried out every year or every two years depending on the type of boiler. Since this is a mandatory expense, it may be convenient to sign assistance contracts with the company you are contacting, which guarantee a series of interventions at discounted prices. These contracts allow for annual savings of 10-15% depending on the company and the contract itself.

Finally, it is essential to dwell on one point. Today, many purchases are made online because online shops and e-commerce can save money on a range of products. Among these products, there are also many latest-generation boilers, that is condensing boilers, which are sold at highly competitive and affordable prices. These are models of excellent workmanship, of well-known and less known brands.

However, even when you choose to buy a boiler online, even if you are sure that you are an expert and therefore choose a truly affordable and latest generation model, you cannot think of being able to install it yourself. To carry out the first ignition, in fact, just like for maintenance, a qualified technician is required, not only for greater safety in the installation, but also and above all to activate the guarantees, for the issue of the blue sticker (i.e. the combustion efficiency), to authenticate the boiler booklet and to record the first smoke check.
