Metaloterm UP

The Metaloterm UP system is a modular twin wall flue system, made of stainless with an air gap insulation and sealing ring. Metaloterm UP is suitable for high and low temperatures, condensing and non-condensing applications with flue gasses in positive or negative pressure and it is even chimney fire resistant. Due to the special inner wall of AISI 904 it is more corrosion resistant. There for it is suitable for biomass fuelled applictions where the fuels are not free from aggressive acids. For example pellet fired stoves or central heating devices.
