Vaillant aroSTOR VWL 290 Twin Flue Kit | 20205775 | Single Wall Penetration Ducting
Vaillant aroSTOR VWL 290 Twin Flue Kit (Part 20205775) — Genuine Vaillant accessory for aroSTOR 200L and 270L heat pump water heaters | Routes both air intake and exhaust through a single wall penetration | Expands siting flexibility where separate duct runs are not practical | Part No. 20205775 | GTIN: 4024074750865 | Kit weight: 4.5 kg
This twin flue kit is designed specifically for the Vaillant aroSTOR VWL B 200/5 UK (article 0010024440) and VWL B 270/5 UK (article 0010028218) floor-standing integrated heat pump water heaters. It is not compatible with Vaillant aroTHERM, ecoTEC, or other Vaillant products.
The Vaillant aroSTOR VWL 290 Twin Flue Kit is an official Vaillant accessory that allows both the air intake and exhaust ducts of the aroSTOR 200L or 270L to be routed through a single wall penetration. Without this kit, two separate wall or ceiling openings are required — one for the warm air intake and one for the cooler exhaust discharge. The twin flue arrangement consolidates both into one opening, which is particularly useful where the available wall space is limited, where aesthetics require a tidy external finish, or where the aroSTOR is located close to an external wall.
When using the aroSTOR in external air mode (drawing fresh outside air rather than recycling indoor air), the twin flue kit simplifies installation considerably by replacing two individual duct runs with a single co-routed system. It is supplied as a complete Vaillant-engineered kit to ensure full compatibility with the aroSTOR's air connection apertures and maintain the unit's warranty.
