Our chimney packs provide you with a suitable and coordinated system from a single source.

The upgrade for your chimney

Everything from a single source

The chimney system from ÖkoFEN is reliable, durable and economical. You only need one contact for refurbishing your whole heating and chimney system. The tedious search for the right chimney has come to an end and your contractor can order it from ÖkoFEN at the same time as your heating system.

Completely compatible

The chimney refurbishment pack is a perfect match for our pellet condensing boilers and conventional pellet boilers. Apart from the pack, other accessories and connection pipes can be ordered individually to suit your local circumstances.

Straightforward system planning with intelligent accessories

The ÖkoFEN connection pipe is the perfect, simple, reliable solution for connecting an ÖkoFEN pellet boiler to the chimney. It has been developed specifically for our boilers and is CE-certified jointly with them as part of the boilers. This makes it ideally suited and technically compatible and it is further characterised by its ease of installation.

Talk to experts

In general, all details of the planned design of the flue gas system must be agreed in advance with the responsible flue gas inspector. They will offer you comprehensive, competent, independent advice about your chimney.

Convenient heating

With a pellet condensing boiler, the chimney stays so clean that the chimney sweep does not need to clean it more than twice a year – similar to an oil boiler. So you can continue enjoying convenient yet environment-friendly heat in your home.

Clean technology

Quite naturally, the flue gas is even cleaner thanks to modern condensing technology. Fine dust particles in the flue gas bind with the condensate instead of escaping through the chimney.
Our condensing boilers boast extremely low dust levels thanks to the sophisticated combustion technology and control systems.

MD system description
Single-walled, metallic-sealing, stainless steel flue gas system

Single-walled, tapered-section, metallic-sealing, soot-fire-resistant, stainless steel flue gas system for chimney refurbishment.

The components are made of a high-alloy stainless steel resistant to intercrystalline corrosion. The smooth-walled, rigid stainless steel elements feature an outwardly tapering coupling sleeve and a bead to interrupt capillary action. The bead also helps improve stability. The tapered design means that the plug-in connections are metallically sealed. This makes the system suitable for both underpressure and overpressure operation and seals it against condensate.

The structure at a glance

for better protection against escaping flue gas and condensate and no blocking of the condensate drain:

Metallic sealing – tapered plugging
Cleaning apertures fitted with sealed high-temperature cover
Condensate shell with DN50 connection (practical connection for HT pipe)

General information for planning the flue gas system

All details of the flue gas system design must be agreed in advance with the responsible flue gas inspector.
When planning and installing the flue gas system, pay careful attention to the planning documents and installation manuals for the flue gas system and pellet boiler.
