Good reasons for modernising your heating system and using efficient gas condensing technology
In Germany alone, there are still around two million heating systems in use today that are more than 25 years old. Their owners are often completely unaware of how much money they are wasting unnecessarily on energy, which is pointlessly burned up and exits the chimney as unused heat. Furthermore, these old systems have an impact on our climate through unnecessary CO2 emissions which contribute to global warming.
By promptly replacing these systems with highly efficient condensing boilers combined with solar technology, end users can shave their energy consumption by up to 35 percent. This would translate into ten percent of Germany's total energy needs, with annual CO2 emissions being reduced by 54 million tonnes at the same time.
Central heating backup with solar energy
The free energy delivered by the sun is still not used enough for central heating backup and DHW heating. When modernising, you should consider combining your new heating system or boiler with a solar thermal system.
How to save with condensing technology
With condensing technology, not only is the heat from the combustion of gas utilised, but also the heat that, with conventional heating equipment, would escape unused up the chimney.
Condensing boilers extract almost all of the heat in flue gases and convert it into additional heating energy. To do this, Viessmann condensing boilers are equipped with stainless steel Inox-Radial heat exchangers, which cool the flue gases before they are routed into the stack, to the extent that the water vapour contained within them is deliberately condensed. This frees up additional heat which is transferred into the heating system.
With this technology, condensing boilers achieve a standard seasonal efficiency [to DIN] of up to 98 percent, and so are particularly energy efficient. This function not only saves valuable energy, but also protects the environment through significantly lower CO2 emissions.
