The all-purpose solution for domestic and commercial use

AVANT KW is Convesa’s most comprehensive and versatile modular double-wall chimney. It is designed to work with any type of fuel in small and medium-sized installations.

Its double-wall construction (AISI 316L inner wall, resistant to corrosion and acidic condensates, and AISI 304 outer wall) maintains flue gas temperature, prevents condensation, improves draught and enables safe passage through floor slabs, false ceilings and façades.

Single-family homes, small residential communities, commercial premises and hospitality establishments.
