Technical Specifications
Heart of Stainless Steel
ACV’s 80 years of experience using stainless steel in heating and hot water production
have led to the development of a new heat exchanger in stainless steel which is at the
heart of the Prestige 24-32.
Since there is no oxidation in the exchanger, the Prestige attains exceptional output
with efficiency remaining constant throughout the life of the boiler.
The Prestige is also self-cleaning – by trickling along the flue gas pipes, the
condensates constantly clean any combustion residues. The boiler continues to
function at very high output, and maintenance is limited to the routine annual visits.
