Condensing boilers represent a technologically advanced and sustainable solution for home heating and the production of domestic hot water. The operation is based on a principle which, compared to traditional boilers, we can define as revolutionary, namely the recovery of the latent heat contained in the combustion fumes, usually dispersed into the environment. This system makes it possible to achieve efficiencies greater than 100% of the lower calorific value of the fuel, a case which will perform a dual action: increasing energy efficiency and significantly reducing harmful emissions.
The introduction of increasingly stringent regulations regarding energy efficiency and environmental sustainability has made condensing boilers the preferred choice for those who want to reduce energy consumption without sacrificing comfort.
Reduction of consumption
From a consumption point of view, these devices offer concrete advantages: they can reduce energy needs by up to 30% compared to traditional boilers. For an average family, this translates into annual savings that can reach 200-300 euros on the gas bill, compared to an initial investment which, thanks to the current tax deductions available until 12/31, can be amortized in 4 -5 years.
Compared to conventional models, condensing boilers are designed to work best at low temperatures, which makes them a perfect match for underfloor heating systems and new generation radiators.
Are they more sustainable?
Environmental sustainability is another key aspect. Condensing boilers significantly reduce CO2 emissions: a reduction of up to 25% is estimated compared to conventional models. A figure that is particularly relevant considering that domestic heating accounts for approximately 15% of greenhouse gas emissions in Italy.
How to choose a condensing boiler
Choosing a condensing boiler requires attention to various aspects to ensure a purchase suited to your needs. It is essential to consider the power necessary, which depends on the size of the home and the domestic hot water requirement. The most efficient boilers use technologies such as burner modulation, which optimizes consumption by adapting power to real needs. Also worth evaluating dimensions and design, especially if installation space is limited. Don’t neglect compatibility with underfloor heating systems or modern radiators, and check that the model complies with energy regulations (ErP). Finally, you should consider additional features such as connecting to smart thermostats or remote control apps, which improve efficiency and convenience.
What are the best condensing boilers
In the current market, there are many options available and include models with advanced technological features, such as digital adjustments, compatibility with mixtures of natural gas and hydrogen, and compact designs for versatile installation. Among the leading brands in the sector, Viessmann, Beretta and Riello stand out for the high quality of their products and commitment to sustainable innovation.
