Gas fired heating - how it works and what it brings

Compared to conventional gas heating, gas fired heating brings significant energy savings and is much more ecological. There are also some differences. Read more here.

The efficiency is the decisive advantage

While gas heaters in and of themselves already have a very high efficiency, this physical value is still significantly higher for a gas fired heating. Theoretically, it is even 111% in some heating systems - that is, more heat is generated than is actually stored in the gas in energy.

The difference in gas fired heating is simply that it also recovers the heat contained in the fumes, which would otherwise escape through the chimney. This not only converts the energy stored in the gas into heat, but also uses the additional energy released by the combustion process.

Therefore, gas condensing systems do not need a chimney. This advantage is sometimes even in new buildings or when retooling positive effect.

In terms of cost, gas fired heating systems are still relatively cheap - even with constantly rising gas prices - and in many cases, due to their high efficiency, they can still compete with more sustainable systems in terms of cost.

The problematic situation with fossil fuels

In view of the ever increasing scarcity of fossil fuels and above all oil, and the associated price increases, however, gas fired value heaters are not a truly sustainable and future-proof heating solution. At best, the conversion of existing systems can mean an advantage in the medium term.

Of course, such efficiency also keeps heating costs within acceptable limits - at least for now. Cost increases are easily preprogrammed for gas.

In addition, gas also has a significant CO2 problem - overall, it is lower than oil, but still available. From a purely ecological point of view, gas is therefore not necessarily optimal.

Tips & Tricks

When it comes to the conversion and renewal of the old heating system, you should not forget to consider and calculate environmentally sound alternatives. Combined heat and power plants, photovoltaics and solar technology today, as well as biomass heating systems, often offer significant cost advantages in operation, which can then pay off in the long term. Therefore always keep an eye on the variety of alternative options.
