SAUNA & JACUZZI CHIMNEY SYSTEMSHeat, humidity and steam.
Heat, humidity and steam.
One dependable system.
Acid-resistant HENITOM systems safely discharge flue gases from wood-fired sauna stoves, garden hot tubs, jacuzzis and other compact solid-fuel appliances.
A complete route inside or outside the spa zone
Choose the single-wall SK system for a suitable existing shaft or the insulated SKI system for an external, standalone route. Both use compatible, precisely joined stainless-steel modules.
SK
Single-wall acid-resistant system
A modular chimney insert for installations routed through a suitable internal shaft, designed for natural draught and demanding humid conditions.
SKI
Insulated double-wall system
A self-contained external chimney with non-combustible mineral-wool insulation for sauna cabins, garden spa installations and freestanding appliances.
Safety and reliable draught in a hot, humid environment
Moisture resistance
Acid-resistant stainless steel protects the chimney against humidity, water vapour and aggressive condensate.
Thermal protection
The insulated SKI variant limits surface heating and supports fire-safe external installation.
Fast, stable draught
Low thermal inertia helps the flue warm quickly so the appliance can operate efficiently.
A finish that belongs
Clean stainless steel and optional colour finishes integrate neatly with timber cabins and garden architecture.
SYSTEM SELECTION
Start with the appliance and installation route
The safest solution is based on the complete installation, not one component. Confirm these three points before ordering:
Which appliance will the chimney serve?
Sauna stove, hot-tub heater, jacuzzi heater, pizza or bread oven, or a freestanding fireplace.
Where will the route run?
Use SK inside a suitable shaft. Choose insulated SKI for an external, facade-mounted or standalone chimney.
What are the project dimensions?
Confirm outlet diameter, appliance output, required height, offsets, clearances and the roof or wall transition.
WHERE THE SYSTEM WORKS
One modular answer for compact solid-fuel appliances
The system is intended for compatible solid-fuel appliances operating under natural draught. Final diameter, clearances and configuration must be confirmed for the appliance and local installation requirements.

Frequently asked questions
Is the same system suitable for a sauna and a wood-fired hot tub?+
Yes, subject to appliance data and correct sizing. The route, outlet diameter, operating temperature and clearances must be verified for each installation.
When should I choose insulated SKI?+
Choose SKI when the chimney runs outside the building, passes close to accessible areas or needs its own thermal protection. Its 50 mm mineral-wool layer stabilises conditions and reduces surface temperature.
Can the chimney be made in a colour matching the sauna?+
Selected powder-coated colour variants and custom elements can be prepared on request, subject to the project specification.
How is the chimney diameter selected?+
Diameter depends on the appliance outlet, output, fuel, route and effective height. Send these details and a simple sketch to the technical team.
Does the system require inspection and cleaning?+
Yes. A qualified professional should inspect and clean the chimney at intervals required for the appliance, fuel and local regulations.
