Ravenheat have been manufacturing boilers for over 20 years, and are known for producing products with high energy efficiency, combined with the introduction of new technologies.  The 780 Series is the latest edition to our current range of reliable, cost effective, high performance combi boilers. 

This product is an easy to install, Sedbuk Band A rated, small economic energy saving boiler with atmospheric combustion. Distinguishing feature is the oval shape control panel, stylish and easy to clean with integrated side panels.  Dimensions of the boiler measures only 310 (D) x 770 (H) x 450mm (W).

How does it work?

The CSI 85AAA 780 Series (Band A) 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.
