ECOPOOLTECH Wood-Fired Hot Tub & Pool Heater

The ECOPOOLTECH wood-fired heater offers a practical, off-grid way to warm your hot tub, jacuzzi or small outdoor pool without relying on electricity or gas. At the heart of the unit is a corrosion-resistant titanium heat exchanger, which transfers heat more efficiently than standard stainless steel alternatives and holds up well against salt water and chemically treated water alike. A compact circulation pump keeps water moving through the system, while the wood stove itself runs entirely on natural fuel, keeping running costs low.

The generously sized combustion chamber is designed to sustain a continuous burn, which means less time tending the fire and faster heat-up times overall. The whole unit is lightweight and straightforward to set up, making it a good option if you want a flexible heating solution that can move between locations or be stored away between uses. A spark arrester fitted to the chimney adds a sensible layer of safety when burning outdoors.

Beyond hot tubs, this heater is well suited to small swimming pools up to around 1,000 gallons and can even serve as a practical way to keep large livestock drinkers from freezing in winter. If you're looking for an economical, fuel-flexible heater for outdoor water without the need for mains power, this is a versatile and solidly built choice.
