Wood-Fired Hot Tubs with External Heater
A classic choice that blends proven reliability with flexible installation. Hot tubs with external heaters deliver an authentic wood-fired experience, with the heating unit positioned separately for easier access, improved safety and practical maintenance.
Discover the Benefits of an External Heater
External heater systems are a popular option for good reason:
- Flexible installation – position the heater for safe clearances and convenient access
- Simple maintenance – external units are easier to clean and service
- Improved safety – the heater is kept separate from the bathing area
- Traditional design – a time-tested wood-fired setup trusted for generations

How the External Heating System Works
The external heater is a separate wood-burning unit connected to the tub via a circulation system. Water is drawn through the heater, warmed efficiently and returned to the tub. This setup allows you to tend the fire safely outside the bathing area while still achieving excellent heating performance. Most tubs reach optimal temperature within 2–3 hours, depending on size and conditions.
Because all heating components are external, servicing and cleaning are straightforward and placement can be adapted to suit your layout and ventilation requirements.
Wood-Firing Tips for Best Results
For efficient heating, use well-seasoned hardwoods such as:
- Oak
- Ash
- Beech
Ensure firewood has been dried for at least 12 months and has a moisture content below 20%. This improves heat output, reduces smoke and ensures a cleaner burn.
Customisation Options
External heater systems are highly adaptable, making it easy to personalise your hot tub:
- Choice of wood cladding and finishes
- Fibreglass or acrylic interior options
- Flexible heater positioning and connections
- Hydrotherapy upgrades (jets, air systems, or both)
- LED lighting and control systems
Customization Options We Offer
We can create your perfect integrated wellness experience because our combo units offer extensive personalization options that coordinate both components for seamless aesthetic and functional harmony.
- Wood finish coordination (thermo wood or spruce across both units)
- Roof colors and materials (bituminous tiles in black, red, or green)
- Sauna configurations (different sizes and window arrangements)
- Hot tub massage systems (hydrotherapy jets, air bubbles, or combination)
- LED lighting packages (coordinated lighting across both components)

When planning your layout, remember to allow space for safe and practical positioning of the external heater.
