Condensing boilers: how to choose the right one for you

Have you decided to replace your old boiler and are thinking of switching to a condensing boiler? Good choice! Condensing boilers are considered among the most efficient and innovative heating solutions available on the market. In this article, we will guide you through the main aspects to consider when choosing a condensing boiler, to help you make the right decision for your needs.
Advantages of condensing boilers:
Condensing boilers are a type of boiler that uses the heat from exhaust fumes to heat water. This process allows the heat otherwise wasted to be recovered and used to increase the efficiency of the heating system. The result is significant energy savings and a reduction in CO2 emissions.
Condensing boilers offer numerous advantages compared to traditional boilers. Here are some of the main advantages:
Greater energy efficiency: Thanks to the recovery of heat from exhaust fumes, condensing boilers can achieve an energy efficiency of over 90%. This translates into significant savings on heating costs.
Reduction of CO2 emissions: Condensing boilers are more environmentally friendly than traditional boilers, as they produce fewer CO2 emissions.
Savings on heating costs: Thanks to greater energy efficiency, condensing boilers allow you to reduce heating costs. In the long term, this can represent a significant cost saving.
Greater comfort: Condensing boilers are able to provide a greater quantity of domestic hot water, ensuring greater comfort in daily life.
Longer life: Condensing boilers are usually designed to have a longer life than traditional boilers, thanks to the use of high-quality materials and better design.

How condensing boilers work

The operation of condensing boilers is quite simple. During the heating process, the boiler burns gas or fuel oil to produce heat. The exhaust fumes generated by this process still contain a significant amount of heat.
In traditional boilers, these exhaust fumes are simply expelled into the atmosphere. However, in condensing boilers, the exhaust fumes are cooled and condensed, while the heat is transferred to the water circulating in the heating system. This process of condensation of the water vapor present in the exhaust fumes contributes to the energy efficiency of condensing boilers.
The energy efficiency of condensing boilers is measured through the energy classification. Condensing boilers are rated based on their energy efficiency and receive a letter from A++ (most efficient) to G (least efficient).
Condensing boilers belonging to the A++ class are the most efficient on the market and offer significant energy savings. These boilers are able to recover up to 98% of the heat from the exhaust fumes.
It is important to note that class A condensing boilers can benefit from tax breaks, such as the 65% Ecobonus. Therefore, it is advisable to opt for a condensing boiler of at least class A to maximize energy efficiency and benefit from the tax advantages available.

Power, dimensions and position of the boiler, important data to consider:

The power of the boiler is another important aspect to consider when choosing a condensing boiler. The power of the boiler must be suitable for the size of your home and your heating and domestic hot water needs.
Boiler power is measured in kilowatts (kW) and depends on several factors, such as the surface area of the home, thermal insulation, the number of bathrooms and the number of people using hot water at the same time.
In general, for an average-sized house with only one bathroom and a standard domestic hot water requirement, a condensing boiler with a power of 24-30 kW should be sufficient. However, if your home is larger or has a greater demand for hot water, you may need a boiler with a higher output.
It is always advisable to consult a professional in the sector to determine the ideal boiler power based on the specifications of your home.
Condensing boilers can be installed both inside and outside your home. The choice between an internal or external condensing boiler depends on your needs and the characteristics of your home.
Installing an internal condensing boiler brings some advantages, such as lower energy consumption, longer life and simpler management.

And. However, you may need adequate space for installation.
On the other hand, installing an external condensing boiler can be a good option if you have a suitable outdoor space, such as a terrace or garden. This type of installation can be more convenient if you are replacing an older outdoor system.
Regardless of your choice of location, it is important to ensure that the installation is carried out by an experienced professional to ensure safe and efficient operation of the boiler.
