Wood-fired hot tubs offer a rustic, natural soak with crackling fire ambience. But do they need electricity to run? Below, we explain how wood-burning tubs work, when (and why) power may be required, and easy ways to get the most from an off-grid setup—plus helpful links to related guides across our blog.
Wood-Fired Hot Tubs: An Overview
Also called wood-burning hot tubs, these models are typically built from durable, high-quality timber. Unlike electric or gas spas, wood-fired tubs heat water with a real fire for a traditional, eco-minded experience. If you’re comparing stove types and layouts, see our overview of hot tub heating options.
Do Wood-Fired Hot Tubs Need Electricity?
No—wood-fired hot tubs do not require electricity to heat water. The fire provides the heat, so you can enjoy a warm soak even off-grid or during power cuts. Power is only needed if you add accessories such as a filtration system, massage jets, or LED lighting. For planning power points and safe connections, review what connections you need before owning a hot tub.
Because there’s no thermostat controlling a stove, wood-fired hot tubs are hands-on: you manage the fire and check the temperature. If you prefer greener habits while you heat, browse our eco-friendly hot tub tips.
How Do Wood-Fired Hot Tubs Work?
Wood-fired tubs use a simple, effective setup: a wood stove/burner with a chimney and a water circulation path. The stove sits outside the tub and connects via pipe/hoses. Light the fire and let it burn until the water reaches your preferred temperature; heat transfers as water circulates through the system for a soothing, natural soak.
Advantages of Wood-Fired Hot Tubs
- Environmentally friendly: Use a renewable, natural fuel source.
- Lower operating costs: Wood is generally cheaper than electricity or gas.
- Timeless aesthetics: The rustic look elevates your outdoor space.
