Heating: condensing technology explained in 5 easy steps
| modified: 20 May 2022
Let’s admit it: even though we hear more and more talk about condensing technology, we’re still not exactly sure how it works and above all what the benefits are in terms of efficiency and savings?
So, this little guide is exactly what we need: five questions and answers that provide a simple explanation of how condensing boilers work and why they’re the right choice for a sustainable future.
1. What’s the main difference between a traditional and a condensing boiler?
Flue gas from traditional boilers loses water vapour produced by combustion, and therefore also the latent heat produced, to the atmosphere. This “lost” heat is called “latent” because it can’t normally be used, but calculations show it to be around 11% of the energy generated by combustion.
Condensing boilers, on the other hand, recover some of this heat before the combustion fumes are vented and put the energy thus obtained back into the heating circuit.
2. Why is condensing technology efficient?
A condensing boiler recovers from flue gas a certain amount of heat that would otherwise be lost to the atmosphere and uses it to heat water for the heating system. This means lower consumption than a traditional boiler and therefore higher efficiency.
3. How much can be saved with a condensing boiler?
According to data published by ENEA (National Agency for New Technologies, Energy and Sustainable Development), condensing technology enables savings of around 20% on gas bills compared to traditional boilers. But with Ariston’s class A condensing boilers we can save even more: here, for example, we can calculate how much we can save with Ariston’s ALTEAS ONE NET.
4. Can a traditional boiler be replaced by a condensing boiler?
Condensing boilers can be installed in any type of home and replace traditional boilers without any problems. And if you decide on such a replacement, don’t forget there are tax benefits (65% or 50%) under law XXXXX ). Click here to find out how to obtain such benefits when buying an Ariston condensing boiler.
5. Why are condensing boilers more eco-sustainable than traditional ones?
Condensing boilers are considered an eco-sustainable means of heating because they guarantee reductions of up to 75% in harmful gas emissions (CO2 and NOx - nitrogen oxides).
