CSI System AAA 780 (T) Advanced Combination Condensing Boiler
The 780 Series is a new edition to our current range of reliable, cost effective high performance system boilers.
The CSI System AAA 780 (T) Series (Band A) condensing boiler works far more effciently than traditional boilers. This boiler recovers most of its heat by condensing heat from the fumes allowing it to achieve over 90% Sedbuk efficiency. In other words it extracts more heat from a smaller quantity of fuel. The reason for this is a second aluminium heat exchanger. This increased effciency is obtained by reducing the temperature of the flue gases to the point where water vapour produced during combustion is condensed out. This releases latent heat which would otherwise escape. By extracting the heat, the nett result gives lower gas bills
