Why use a condensing boiler?

• New condensing boilers fulfil strict EU economic and ecological criteria on heat sources and are thus promising into the near future when the installation of classic heat sources will be forbidden even in Slovakia
• In comparison with modern versions of classic boilers, they consume less natural gas (up to 15% less), which in the long term means significant savings in heating and DHW heating.
• Condensing boilers are less of a burden on the environment with significantly lower COx and NOx emissions.
• Another big advantage of condensing boilers is the large modular output range, allowing the desired output to be set even for systems with low heat loss, operating at a low output normally, but at maximum output when heating DHW, which speeds up and increases the amount of DHW heated either with through-flow technology or in an external tank
• It is not true that condensing boilers are suited only for underfloor heating with a low temperature gradient - they are also suitable for systems with a higher temperature gradient (98% efficiency with a gradient of 80 / 60°C), making it possible to use them even in older heating systems, for example when a boiler is replaced
• In connection with climate changes and the onset of more moderate winters, the proportion of time when the boiler is functioning in full condensing mode is growing, again making condensing boilers more favorable from the standpoint of gas usage even in outdated systems designed for larger temperature gradients during harsh winters
• With the development of new technologies and the greater use of common components, the difference between the sales prices of condensing and classic boilers is gradually shrinking
