The CSI 85 AAA (T) 780 Series is the latest edition to our current
range of reliable cost effective, high performance combi
boilers. This model is an easy to install Sedbuk Band A rated,
small economic energy saving boiler with atmospheric
combustion. A distinguishing feature is the oval shape control

panels. Dimensions: 310 (D) x 770 (H) x 450mm (W).

How does it work?
The CSI 85 AAA (T) 780 Series condensing combi
works far more efficiently 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 efficiency 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.
