Why People Choose Wood-Fired
Simplicity
No electrical connection required.
Atmosphere
Firelight, timber, water, and fresh air.
Flexibility
Install almost anywhere without requiring a fixed electrical connection.
How wood-fired works
Pre-assembled arrival
Arrives fully built and pre-engineered to your property. No complex structural assembly required. Position it on your level foundation, fit the chimney flue on site, and your setup is ready.
Fill
Prepare the tub by filling the non-porous stainless steel core with fresh water directly from a standard garden hose.
Ignite the fire
Light the fire inside the fully submerged furnace and let the water gradually warm around it.
Step in & soak
Once the water reaches your preferred temperature, step into an authentic, deeply rewarding outdoor ritual that feels entirely removed from a powered spa system.
The Andes Furnace Difference
Why Internal Furnace Design Matters
Unlike external heating systems that rely on long pipe runs and circulation loops, the Andes furnace sits directly within the water it heats.
By surrounding the fire with water, heat transfers directly into the tub with less loss and greater efficiency.
- Faster heating
- Higher thermal efficiency
- Less heat loss
- Cleaner integrated appearance
- Fewer external components

FAQs
What's the difference between wood-fired and hybrid?
Wood-fired is heated only by the built-in firebox. Hybrid lets you switch between wood-fire and electric heating, or use both (fire to heat, electric to maintain).
What type of wood should I burn?
Use clean, dry hardwood (e.g. ironbark, spotted gum, red gum). Avoid treated timber, painted wood, or softwoods with high resin.
How long does a wood-fired hot tub take to heat?
Typically 1.5 to 3.5 hours depending on starting water temperature, weather, wood type, and tub size.
Can I use it during a fire ban?
No. Wood-fire operation is not permitted during a fire ban. Electric-only use (on hybrid models) may still be possible depending on local restrictions.
How often should I change the water?
Every 2–6 weeks depending on usage, filtration, and water care routine.
Can wood-fired hot tubs be used off-grid?
Yes. Wood-fired models can operate fully off-grid with no electricity required (aside from optional filtration or lighting if installed).
Do I need experience with wood fires?
No. It’s simple to learn. If you can safely manage a fireplace or BBQ, you can operate it. Basic guidance is provided on setup and first use.
