C.H.System Installations

Condensing technology not only utilises the heat generated by combustion as a measurable temperature of the hot gases (net calorific value), but also the water vapour content (gross calorific value). Condensing boilers are able to extract almost all of the heat contained in the flue gases and to convert it into heating energy.
Condensing boilers use high performance heat exchangers. These cool the flue gases before they escape through the chimney, to the extent that the water vapour contained in these gases is deliberately condensed. This releases additional heat which is transferred into the heating system.

With this technology, a gas condensing boiler achieves a standard seasonal efficiency [to DIN] of up to 98 % (relative to Hs). Condensing boilers are therefore particularly energy efficient, looking after both your wallet and the environment.

Calorific value (Hs)

The gross calorific value (Hs) defines the amount of heat released by complete combustion including the evaporation heat latent in the water vapour of the hot gases.

The MatriX gas burner

The MatriX gas burner represents a milestone in Viessmann heating technology. The use of the stainless steel MatriX gauze endows it with a long service life. The burner is resistant to high temperature loads.

Viessmann Heat Exchanger

Viessmann Heat Exchanger
In 1995 Viessmann developed the Inox-Radial stainless steel heat exchanger. At the heart of all Vitodens wall mounted condensing boilers is a corrosion-resistant, high-alloy stainless steel Inox-Radial heat exchanger. A key component to outstanding efficiency, this high performance heat exchanger also delivers proven reliability and a long service life.
