Single-Wall Stainless Steel Chimney Systems RENOFAST

RENOFAST — Professional Chimney Systems from Manufacturer Akvilon

RENOFAST is a single-wall stainless steel chimney system designed and manufactured in Latvia. It is the primary choice for renovating existing brick chimneys and connecting boilers, stoves, and fireplaces inside the house.

The system combines manufacturing precision (laser cutting, robotic TIG welding) with high-quality materials, meeting the strictest European standards CE EN 1856-2.

Quick Check: Is RENOFAST right for you?

Before ordering, please ensure this system fits your installation conditions:

Yes, if you have a brick chimney: You want to insert a liner to protect masonry from condensate and improve draft.
Yes, if you need a connection: You need to connect a boiler or stove to a chimney indoors (e.g., in a boiler room).
No, for outdoor installation: Single-wall pipes cannot be used outside or in cold attics. For these areas, use our IZOKOMPAKT insulated double-wall chimneys.

Choose the Right Solution for Your Heater

We cover 100% of flue gas extraction needs by offering three specialized product lines:

Round Systems (Universal)

Best for: Connecting boilers, stoves, and building new internal flue runs.
The classic choice with the best aerodynamics and easy cleaning. Minimal flow resistance prevents soot buildup.

Oval Liners (For Brick Shafts)

Best for: Relining rectangular brick chimneys.
The oval shape allows you to preserve the maximum useful cross-section of a narrow brick shaft where a round pipe would be too small.

RENOFAST T200 (For Gas)

Best for: Modern gas condensing boilers.
A special series with silicone gaskets (Class P1). It guarantees 100% gastightness when working with wet steam and pressure.

Advantages of Buying from Manufacturer

Socket Geometry: We do not use manual forming. All connections are machine-calibrated, ensuring an easy "pipe-in-pipe" fit without gaps.
Stock Program: We keep in stock not only pipes but also complex fittings (tees, elbows, adapters). You can complete your project in one visit.
Honest Steel: We do not compromise on thickness. If 0.6 mm is stated, you get real 0.6 mm of certified AISI 304 or 316L steel.
Direct Price: Buying from Akvilon factory, you avoid dealer markups.
