How Does It Work?

Ravenheat's CSI 85b(T) condensing combi boiler works far more efficiently than traditional boilers. Conventional units lose up to 30% of their heat through the flue, whereas this model recovers most of this heat by safely condensing heat from the fumes, thereby achieving efficiencies of 96%.

Unique Heat Exchanger
After the initial fitting of the heat exchanger and fan, the boiler is equipped with Ravenheat's unique and patented, aluminum heat exchanger. This self contained unit not only ensures that the maximum heat is extracted from the outgoing flue gasses but that the fumes are safely guided away. We are the only U.K. manufacturer currently fitting a second plate heat exchanger after the exhaust fan. Up to 96% of gas used is converted into heat for hot water and heating.

A unique heat exchanger extracts heat from otherwise wasted exhaust gases

Increased Efficiency
The CSI System Condensing Boiler is designed to extract more heat from a smaller quantity of fuel. The reason is a second aluminum heat exchanger. This increase in efficiency is obtained by reducing the temperature of the flue gases to a point where water vapour produced during combustion is condensed out. This releases latent heat which would otherwise escape with the flue gases. Simply by extracting the heat from the flue gasses, the nett result gives lower gas bills.

More efficient means reduced emissions
With the depletion of the rain forests and commitments by governments worldwide to a reduction in green house gas emissions, its good to know that Ravenheat is
playing a part in cutting fuel consumption. In addition, users of Ravenheat's new CSI 85b(T) can be assured too that they will be playing a key role in saving energy and ensuring that flue emissions of nitrous oxide and carbon dioxide are kept to a minimum, which is excellent news for the environment.
